Perineal techniques during the second stage of labour for reducing perineal trauma

SAFE PASSAGES Training Decreased the Incidence of Perineal Trauma During Childbirth

BACKGROUND

Active-duty women of childbearing potential comprise a significant portion of service members in the United States (US) Armed Forces. Obstetrical anal sphincter injuries have been associated with significant morbidity including anal incontinence, rectovaginal fistula, and pain. In the early 2000s, the US Air Force OB/GYN (obstetrics and gynecology) leadership championed the development of a novel education intervention that had the potential to standardize maternal obstetrical care across the DoD.

METHODS

This prospective cohort design focused on quality improvement of patient outcomes by implementing a regimented training program for obstetrical providers. Baseline rates of perineal trauma in spontaneous and operative vaginal deliveries for each of the Armed Services were established using delivery data from January to December 2010 (n = 272,161). While all three services were given grant funds and education materials, only the US Air Force (USAF) implemented a formal SAFE PASSAGES algorithm and training program from January to December 2012. All but one USAF hospital received on-site training. Perineal trauma rates were compared to post-implementation rates (January 2013-September 2014, with 451,446 deliveries).

RESULTS

The USAF hospitals showed a reduction in the rate of perineal trauma while the other two (Army, Navy) did not. Overall, there was a reduction in Patient Safety Indicator (PSI) 18 (lacerations after operative delivery, p < 0.01) and a statistically insignificant decrease for PSI 19 (lacerations after spontaneous delivery; 5.8%; p = 0.07) across the services. Again, USAF hospitals showed the greatest improvement (41.8%, p < 0.01). In USAF hospitals that received on-site training, PSI 18 rates decreased from 18.5/1000 to 6.0/1000, a 309% improvement (p = 0.012).

CONCLUSIONS

The USAF OB/GYN Leadership developed a training program and strategic intervention that is now well-recognized across the Department of Defense and the United States as the standard of care. Decades later, much evidence now supports the tenets of the SAFE PASSAGES training and its historic beginnings.

The Paper Perineum Model: An Accessible Three-Dimensional Model for Obstetric Laceration Simulation and Surgical Education

INTRODUCTION AND HYPOTHESIS

Existing models for obstetric laceration repair often require specialized materials and are time-consuming to construct. We created the Paper Perineum model, a paper template that can be printed, cut, and folded into a three-dimensional representation of the vagina, perineum, and anal sphincter complex. The model is designed as an accessible and low-cost educational tool specifically for nascent learners. Our objective was to assess the model's effectiveness in improving medical students' understanding of obstetric laceration repair.

METHODS

We conducted a prospective pilot study with a cohort of fourth-year medical students matriculating into obstetrics and gynecology residency training. In a workshop environment, students assembled printed model templates and simulated obstetric lacerations to learn the basic steps and surgical techniques involved in repairing lacerations. Students completed surveys to self-assess their knowledge before and after the workshop.

RESULTS

Of the 31 participants, the proportion of students who self-rated their knowledge as "moderate" or "significant" regarding the basic steps of a second-degree perineal laceration repair rose from 2/31 (6.5%) to 31/31 (P < .01); for knowledge of suture planes, the proportion increased from 1/31 (3.2%) to 31/31 (P < .01). Over 90% of students rated the model as either "very helpful" or "extremely helpful" in enhancing their understanding of vaginal and perineal anatomy, anatomical relationships, steps of a perineal laceration repair, and suture planes relevant to such repairs.

CONCLUSIONS

The Paper Perineum model is a readily accessible three-dimensional model that enables basic simulation of obstetric laceration repair and requires minimal advanced preparation from clinician educators. The model is freely available at www.paperperineum.com .

Effectiveness of Intrapartum Perineal Massage in Preventing Perineal Trauma in Nulliparous Women During the Second Stage of Labour: A Randomised Controlled Trial

Objectives: To determine the effectiveness of perineal massage during the second stage of labour in preventing perineal trauma in nulliparous women. Methods: A randomized control trial involving 104 nulliparous women undergoing vaginal delivery. The participants were randomised into two arms (intervention-group 'A' and control-group 'B') in a 1:1 ratio. The intervention group had perineal massage and routine hands-on technique according to the hospital protocol while the control group received only hands-on technique. The primary outcome measure was the incidence of perineal tears during vaginal delivery, while the secondary outcome measures were the incidence of episiotomy during vaginal delivery, the mean duration of second stage of labour, and perineal pain score. Results: The baseline socio-demographic and maternal characteristics of the participants were similar in both arms. The incidence of perineal lacerations in the intervention group (massage group) was significantly lower than in the control group (27 (54%) vs. 40 (81.6%); p=0.003). Although the incidence of episiotomy (26% vs. 44.9%; RR = 0.66; 95% CI = 0.50-0.88; p=0.060) was not significantly different, mean perineal pain score at 4 h postpartum (4.3 ± 0.3 vs. 6.1 ± 0.50; p=0.03), mean perineal pain score at 24 h postpartum (2.2 ± 0.1 vs. 4.2 ± 0.3; p=0.02), and mean duration of second stage of labour (83.1 ± 17.5 min vs. 94.2 ± 18.9 min; p=0.002) were significantly lower in the intervention-group. There was no significant difference in the neonatal outcomes (head circumference, birth weight, and Apgar scores: p > 0.05) between the two groups. Conclusion: Intrapartum perineal massage significantly decreases the risk of overall perineal trauma, perineal pain, and duration of the second stage of labour among nulliparous parturients during the second stage of labour. Nulliparous women should be counselled on the potential benefits of intrapartum perineal massage, and obstetricians are encouraged to provide the technique to consenting women.

Strategies for improving maternal care for ethnic minority women with obstetric anal sphincter injuries in the UK

BACKGROUND

Women from minority ethnic groups in the UK have the highest prevalence of obstetric anal sphincter injuries (OASI), including third- and fourth-degree perineal tears sustained during childbirth. Incorporating the voices of mothers at higher risk of OASI is crucial in developing strategies to improve care and well-being.

AIM

To identify strategies perceived as important by women with lived experience of OASI in Leicester, UK, to improve their care and well-being.

METHODOLOGY

Women at high risk of and with lived experience of OASI in Leicester, UK, were invited, through our local maternity and neonatal voices partnership, to participate in a virtual focus group discussion (FGDs). Two FGDs were conducted to accommodate participants' availability. The first session included seven women, while the second session included three women. All participants were from underrepresented groups with lived experiences of OASI within the past one to ten years. A discussion guide was used to explore participants' perceptions and experiences of OASI care, as well as their views on culturally and linguistically sensitive maternal care strategies. The discussion was recorded and transcribed. The data were analysed using the six-step thematic analysis approach by Braun and Clarke.

RESULTS

The participants identified strategies to provide culturally appropriate care for obstetric anal sphincter injuries, including linguistically accessible prenatal resources, comprehensive midwifery training, updated prenatal education, standardized postpartum care, the inclusion of fathers in prenatal education, empathetic care, building trust, and community engagement and education.

CONCLUSION

This study highlights disparities in maternal healthcare outcomes for women from diverse ethnic backgrounds who experience OASI. Addressing these inequalities requires incorporating the voices of those directly affected to inform culturally sensitive policies and practices in maternal care.

Episiotomy and severe perineal laceration among Asian American, Native Hawaiian, and Pacific Islander nulliparous individuals in California

Background

Asian American, Native Hawaiian, and Pacific Islander individuals have increased risks for episiotomy and severe perineal laceration during vaginal delivery. The Asian American, Native Hawaiian, and Pacific Islander population in the US is diverse yet few studies disaggregate results within specific ethnicity populations.

Objective

This study investigated the variability in risks for episiotomy and severe perineal laceration among 16 disaggregated Asian American, Native Hawaiian, and Pacific Islander groups, compared to Non-Hispanic White nulliparous individuals, and assessed what factors may explain the variability in risk.

Study design

Birth and fetal death certificate files linked to hospital discharge records were used to identify nulliparous, term, singleton, vertex vaginal deliveries among California births, 2007 to 2020. Poisson regression models were used to examine risks of episiotomy and severe perineal laceration among 16 Asian American, Native Hawaiian, and Pacific Islander ethnicity subgroups compared with Non-Hispanic White individuals. Sequential adjustment was utilized to assess if maternal social, health-related, and delivery-related factors may explain the variability in risk for episiotomy and severe perineal laceration.

Results

Among the 224,964 Asian American, Native Hawaiian, and Pacific Islander individuals in this study cohort, the overall prevalence of episiotomy was 18.5% (N = 41,559) and prevalence of severe perineal laceration was 8.9% (N = 20,013); the prevalence of both outcomes declined during the study period. Within subgroups, prevalence of episiotomy ranged from 9.8% among Other-Pacific Islander individuals to 24.5% among Korean individuals. Prevalence of severe perineal laceration ranged from 3.4% in Guamanian individuals to 15.2% in Indian individuals. In fully adjusted models, risk ratios were greater than 1.0 (with confidence intervals excluding 1.0) for 6 subgroups for episiotomy and 9 subgroups for severe perineal laceration, compared to Non-Hispanic White individuals. After adjustment, Korean individuals were at highest risk of episiotomy (adjusted risk ratio 1.80 [95% CI 1.75, 1.85]), and Indian individuals were at highest risk of severe perineal laceration (adjusted risk ratio 2.14 [95% CI 2.07, 2.21]). Adjustment for social factors (nativity; education; payer) tended to attenuate risk ratios; subsequent adjustment for maternal health and delivery-related factors including maternal age, height, pre-pregnancy body mass index, hypertension, diabetes, gestational weight gain, fetal stress/incomplete fetal head rotation (occiput transverse or posterior), large infant size or shoulder dystocia, and forceps/vacuum did not impact risk ratios substantially.

Conclusion

Prevalence and risks of episiotomy and severe perineal laceration varied widely among Asian American, Native Hawaiian, and Pacific Islander births in California from 2007 to 2020. The variability in risks was more influenced by differences in social rather than maternal health and delivery-related factors. This study adds to the growing understanding of disparities in health outcomes among Asian American, Native Hawaiian, and Pacific Islander subgroups.

How time influences episiotomy utilization and obstetric anal sphincter injuries (OASIS)

OBJECTIVES

Obstetric anal sphincter injuries (OASIS) pose significant challenges for young women following childbirth. The association between mediolateral episiotomy and OASIS remains a subject of debate and uncertainty. This study seeks to fill this gap.

METHODS

This retrospective cohort study was performed using electronic database of obstetrics department at a tertiary medical center. All vaginal deliveries and vacuum-assisted deliveries at term, with a singleton live fetus at cephalic presentation between 2015 and 2021, were included. A comparison of the rates of mediolateral episiotomy and OASIS was conducted between the periods 2015-2017 and 2018-2021. Subgroup analysis was carried out based on parity and the mode of delivery.

RESULTS

Overall, the study included 18,202 women. Between 2015 and 2017, episiotomy was performed in 1,272 cases (17.5 %), compared to 1,241 cases (11.4 %) between 2018 and 2021 (p<0.0001). Conversely, a significant increase in OASIS was observed, rising from 0.3 % during 2015-2017 to 0.6 % during 2018-2021 (p=0.012). Multivariable analysis unveiled two factors significantly linked to OASIS: the temporal cohort studied, indicating an increasing trend in recent years, and the utilization of epidural analgesia, which exhibited a protective effect, while episiotomy was not associated with OASIS.

CONCLUSIONS

Our findings indicate a marked decline in the utilization of episiotomy over the study period, accompanied by an increase in OASIS incidence. Nevertheless, our analysis found no statistically significant link between episiotomy use and OASIS incidence.

Improving apgar scores and reducing perineal injuries through midwife-led quality improvements: an observational study in Uganda

BACKGROUND

Globally, the quality of maternal and newborn care remains inadequate, as seen through indicators like perineal injuries and low Apgar scores. While midwifery practices have the potential to improve care quality and health outcomes, there is a lack of evidence on how midwife-led initiatives, particularly those aimed at improving the use of dynamic birth positions, intrapartum support, and perineal protection, affect these outcomes.

OBJECTIVE

To explore how the use of dynamic birth positions, intrapartum support, and perineal protection impact the incidence of perineal injuries and the 5-min Apgar score within the context of a midwife-led quality improvement intervention.

METHODS

A cohort of 630 women with uncomplicated full-term pregnancies was recruited from a hospital in Uganda. Observations and questionnaires assessed birth positions, intrapartum support, perineal protection, health outcomes and maternal characteristics. Primary outcomes included perineal injuries and the 5-min Apgar scores. The primary outcomes were analysed using descriptive data, with trends visualised through a run chart to assess changes during the midwife-led Quality Improvement intervention. Secondary outcomes included postpartum haemorrhage, admission to neonatal intensive care, newborn resuscitation, skin-to-skin care, and breastfeeding initiation.

RESULT

A statistically significant association was found between women having intact perineum (i.e., no perineal injuries) and giving birth in a dynamic birth position [AOR; 0.6 (95% CI 0.4 - 0.90)], receiving intrapartum support [AOR; 0.9 (95% CI 0.9 - 1.0)], and using perineal protection measures [AOR; 0.3 (95% CI 0.2 - 0.5)]. Newborns with an Apgar score below seven at five minutes were significantly associated with intrapartum support [AOR; 0.8 (95% CI 0.7 - 1.0)] and perineal protection [AOR; 0.3 (95% CI 0.1 - 0.8)]. However, after adjustment, no significant association was found between Apgar score and birth positions [AOR; 0.5 (95% CI 0.2 - 1.5)]. Perineal injuries and low Apgar scores significantly decreased (p < 0.001) during the Midwife-led Quality Improvement intervention period.

CONCLUSION

This study demonstrates that low 5-min Apgar scores and perineal injuries decreased during a midwife-led Quality Improvement intervention focusing on dynamic birth positions, intrapartum support, and perineal protection strategies.

CLINICAL TRIAL

This study is registered on ClinicalTrials.gov as of 14th February 2022, under registration number NCT05237375.

Does combining warm perineal compresses with perineal massage during the second stage of labor reduce perineal trauma? A randomized controlled trial

BACKGROUND

Various interventions have been applied to reduce perineal trauma and obstetric anal sphincter injuries (OASIS). The efficacy of warm compresses during the second stage of labor for reducing the occurrence of perineal tears is controversial.

OBJECTIVE

We aimed to compare rates of spontaneous perineal tears requiring suturing, between women who received warm compresses plus perineal massage vs perineal massage alone.

STUDY DESIGN

Women admitted to a single tertiary university-affiliated hospital between June 2023 and January 2024 were randomized to receive warm compresses and perineal massage (n=206) or perineal message only (n=206) during the second stage of labor. Excluded were women with a history of third-degree perineal tear, nut allergy, fetal death, Crohn's disease with perineal involvement, or delivery number >5. Participant allocation was concealed until the second stage of labor. The allocated perineal management was implemented at the time of active fetal descent and when the participant felt the need to push. During active maternal pushing, gentle perineal massage with almond oil was performed in both study groups. In 1 group, warm compresses were applied between contractions, for a minimum of 10 minutes and a maximum of 30. The temperature of the warm compresses was kept in the range of 45°C to 59°C. The perineum was protected during delivery with a hands-on technique. After delivery, the perineum was assessed by an intervention-blinded senior midwife and rectal examination was performed for ruling out OASIS. The primary outcome was the rate of perineal tears requiring suturing. Secondary outcomes included the rates of OASIS and episiotomies. A sub-analysis according to parity and an intention-to-treat analysis were performed.

RESULTS

Similar proportions of women treated and not treated with warm compresses had spontaneous perineal tears requiring suturing: 43.7% vs 45.1%, P value=.766. The groups did not differ in the proportions with first-degree tears, 22.8% vs 21.4%, P value=.722; second-degree tears, 21.4% vs 23.8%, P value=.566; and OASIS rates, 0.5% in each. In a sub-analysis according to parity, the proportion with perineal tears did not differ between the 2 groups.

CONCLUSION

For women treated during the second stage of labor with warm compresses and perineal massage, compared to perineal massage alone, the rate of spontaneous perineal tears requiring suturing was similar. El resumen está disponible en Español al final del artículo.

Hyaluronidase for reducing perineal trauma

BACKGROUND

Perineal trauma after vaginal birth is common and can be associated with short- and long-term health problems. Perineal hyaluronidase (HAase) injection has been widely used to reduce perineal trauma, perineal pain and the need for episiotomy since the 1950s. The administration of HAase is considered to be a simple, low risk, low cost and effective way to decrease perineal trauma without causing adverse effects.

OBJECTIVES

To assess the effectiveness and safety of perineal HAase injection for reducing perineal trauma, episiotomy and perineal pain during vaginal delivery.

SEARCH METHODS

To identify studies for inclusion in this review, we searched the Cochrane Central Register of Controlled Trials, Ovid MEDLINE, Embase, CINAHL (EBSCOhost), ClinicalTrials.gov and WHO International Clinical Trials Registry Platform (ICTRP) in November 2023.

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials comparing women giving birth to their first baby receiving perineal HAase injection compared to placebo injection or no intervention during vaginal delivery of a single foetus with vertex foetal presentation (foetus with head engaging the maternal pelvis).

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Two review authors independently assessed trials for inclusion, extracted and checked data, and evaluated the risk of bias in the studies. Our primary outcomes were perineal trauma (tears or episiotomy, or both), episiotomy and perineal pain. Our secondary outcomes were first and second degree perineal lacerations, third and fourth degree perineal lacerations, perineal oedema 1 hour after vaginal delivery, perineal oedema 24 hours after vaginal delivery and neonatal Apgar scores of less than 7 at five minutes after birth (Apgar score is a measure of the health status of a newborn). We assessed the certainty of the evidence using the GRADE approach.

MAIN RESULTS

We included five randomised controlled trials involving a total of 747 women (data were available for 743 women). The dosage of HAase used in the perineal injection varied from 750 turbidity-reducing units to 5000 international units. The certainty of the evidence was largely low (ranging from very low to moderate). Perineal HAase injection versus placebo injection Data from three trials involving 426 women provided low-certainty evidence that there may be no difference between the HAase and placebo groups in the incidence of perineal trauma (tears or episiotomy, or both) (RR 0.94, 95% CI 0.87 to 1.03; 426 participants, 3 studies), episiotomy (RR 0.91, 95% CI 0.71 to 1.15; 427 participants, 3 studies), first and second degree perineal lacerations (RR 1.02, 95% CI 0.87 to 1.18; 341 participants, 3 studies), third and fourth degree perineal lacerations (RR 0.46, 95% CI 0.11 to 2.05; 426 participants, 3 studies), and perineal oedema one hour after vaginal delivery (RR 0.99, 95% CI 0.78 to 1.25; 303 participants, 2 studies). Moreover, perineal HAase injection during the second stage of labour likely resulted in a reduction in incidence of perineal oedema 24 hours after vaginal delivery compared with placebo injection (RR 0.42, 95% CI 0.26 to 0.70; 303 participants, 2 studies; moderate-certainty evidence). There may be no difference between groups in Apgar scores less than 7 at five minutes (RR 5.00, 95% CI 0.24 to 105.95; 148 participants, 1 study; low-certainty evidence). Perineal HAase injection versus no intervention Data from three trials involving 373 women suggested that perineal HAase injection during the second stage of labour may result in a lower incidence of perineal trauma (tears or episiotomy, or both) (RR 0.61, 95% CI 0.42 to 0.88; 373 participants, 3 studies; low-certainty evidence) compared with no intervention. The evidence is very uncertain for episiotomy (RR 0.79, 95% CI 0.44 to 1.42; 373 participants, 3 studies), first and second degree perineal lacerations (RR 0.59, 95% CI 0.30 to 1.18; 373 participants, 3 studies) and perineal oedema one hour after vaginal delivery (RR 0.32, 95% CI 0.01 to 7.71; 139 participants, 1 study), all very low certainty evidence. No third and fourth degree perineal lacerations, perineal oedema 24 hours after vaginal delivery or Apgar scores less than 7 at five minutes were reported in these three trials. No side effects were reported in the included trials.

AUTHORS' CONCLUSIONS

Perineal HAase injection during the second stage of labour may result in a lower incidence of perineal trauma (tears or episiotomy, or both) compared with no intervention, but not compared with placebo injection, in women having a vaginal delivery. Meanwhile, perineal HAase injection likely reduces the incidence of perineal oedema 24 hours after vaginal delivery compared with placebo injection. The potential use of perineal HAase injection as a method to reduce perineal trauma and perineal oedema remains to be determined as the number of high-quality trials and outcomes reported was too limited to draw conclusions on its effectiveness and safety. Further rigorous randomised controlled trials are required to evaluate the role of perineal HAase injection in vaginal deliveries, including evaluating whether there is any differential effect based on the dose, frequency and positioning of HAase injection.

Patient awareness, knowledge, and acceptability of antenatal perineal massage: A single-center cross-sectional study from Saudi Arabia

INTRODUCTION

This study assessed the knowledge, awareness, and acceptability of antenatal perineal massage (APM) among pregnant women in Saudi Arabia.

METHODS

This cross-sectional study included 240 pregnant women who met the predefined inclusion criteria and attended the Department of Obstetrics and Gynecology, King Faisal Specialist Hospital and Research Center, Jeddah, Saudi Arabia, from 1 October to 31 December 2023. Participants answered seven knowledge questions, classified as having good knowledge if they answered ≥4 correctly and poor knowledge if <4 were correct.

RESULTS

Most women (46.25%) reported it was their first encounter with APM. Common sources of information included the internet (39.58%), physicians/midwives (7.92%), and friends/family (3.75%). Nearly half (47.5%) had heard of APM, but only 8.75% had practiced it, and 3.75% attended related classes. Only 17.5% knew that APM could be performed by the woman or her partner, while 25.83% knew it should start at 34 weeks, and 17.92% recognized the recommended duration of 5 to 10 minutes daily. Additionally, 22.5%, 15.83%, and 35.42% acknowledged APM's benefits for labor duration, anal sphincter dysfunction, and perineal injuries, respectively. The average knowledge score was 1.39±1.84, with 84.17% classified as having poor knowledge. No significant differences were found between knowledge levels (p>0.05). Low acceptability was noted, with only 58% of patients and 37% of their partners willing to engage in APM. No significant differences in acceptability were found between poor and good knowledge groups (p>0.05).

CONCLUSIONS

The study revealed low awareness, poor knowledge, and weak acceptability of APM among pregnant patients. Targeted education for patients and healthcare providers could enhance knowledge and improve maternal-fetal health outcomes.

Ritgen's maneuver in childbirth care: A case-control study in a Central Italian setting

INTRODUCTION

Vaginal delivery can cause genital tract trauma and lacerations of different severity. This study aims to establish if routinary use of Ritgen's maneuver decreases the prevalence and severity of perineal lacerations compared to the traditional manual perineal protection (MPP).

METHODS

This prospective case-control study was conducted in the labor ward of Fondazione Policlinico A. Gemelli, Rome, Italy. One hundred sixteen women who met inclusion criteria were included. The study group (n=58) consisted of women who were assisted using the Ritgen maneuver, whereas the women who gave birth immediately afterward were selected as the control group (n=58). All information was retrieved through electronic medical records.

RESULTS

In all, 22% women of the study group reported no perineal lacerations compared with 5% of the control group (p=0.007). Regarding the degree of lacerations, the study group exhibited more first-degree lacerations and fewer second-degree lacerations, while the control group exhibited the opposite trend. Among women who received epidural analgesia, 24% of the study group did not experience perineal lacerations, compared to 4.5% of the control (OR=0.15; 95% CI: 0.03-0.72; p=0.008). Similarly, 23.4% of cases in the study group with oxytocin-enhanced labor, experienced no perineal trauma while none in the control group had no perineal trauma in cases of oxytocin augmentation (p=0.005).

CONCLUSIONS

Our results suggest that using Ritgen's maneuver in childbirth care may reduce the incidence and severity of perineal lacerations, even in the presence of known risk factors for perineal lacerations such as oxytocin augmentation and epidural analgesia.

Perineal techniques during the second stage of labour for reducing perineal trauma and postpartum complications

RATIONALE

Postpartum haemorrhage (PPH) is responsible for around 27% of global maternal deaths. Perineal tears are common in vaginal births and a significant contributor to excessive blood loss. A diversity of perineal techniques are utilised to prevent perineal trauma and reduce the incidence of PPH; however, they lack evidence-based comparisons to understand their effects.

OBJECTIVES

To assess the effect of perineal techniques during the second stage of labour on the incidence of and morbidity associated with perineal trauma to prevent postpartum complications.

SEARCH METHODS

We searched four databases and two trial registers up to 16 April 2024. We checked references, searched citations and contacted study authors to identify additional studies.

ELIGIBILITY CRITERIA

We included randomised controlled trials (RCTs) of women in the second stage of labour who intended to give birth vaginally, comparing any perineal techniques with control or another perineal technique. We excluded studies that performed perineal techniques outside the second stage of labour.

OUTCOMES

Our critical outcomes were second-, third- and fourth-degree tears measured immediately after birth, and PPH ≥ 500 mL measured within 24 hours after birth.

RISK OF BIAS

We used the Cochrane risk of bias 2 tool to assess bias in the included RCTs.

SYNTHESIS METHODS

We synthesised results for each outcome within each comparison using meta-analysis where possible. Where this was not possible due to the nature of the data, we synthesised results narratively. We used GRADE to assess the certainty of evidence for each outcome.

INCLUDED STUDIES

We included a total of 17 studies with 13,695 participants.

SYNTHESIS OF RESULTS

Hands off (or poised) versus hands on Hands off (poised) may result in little to no difference in second-degree tears (risk ratio (RR) 0.73, 95% confidence interval (CI) 0.32 to 1.64; 2 studies; low-certainty evidence) and third- or fourth-degree tears when data are combined (RR 1.27, 95% CI 0.81 to 1.99; 2 studies; low-certainty evidence). The evidence is very uncertain about the effect of hands off (poised) on third-degree tears and fourth-degree tears when reported separately (RR 0.50, 95% CI 0.05 to 5.27; 1 study; very low-certainty evidence and RR 3.00, 95% CI 0.13 to 71.22; 1 study; very low-certainty evidence). Hands off (poised) may result in little to no difference in PPH ≥ 500 mL (RR 1.16, 95% CI 0.92 to 1.47; 1 study; low-certainty evidence). Hands off (poised) probably results in little to no difference in breastfeeding two days after birth (RR 1.02, 95% CI 0.99 to 1.06; 1 study; moderate-certainty evidence) and perineal pain (RR 0.98, 95% CI 0.94 to 1.01; 1 study; moderate-certainty evidence). Vocalisation versus control Vocalisation may result in a reduction in second-degree tears (RR 0.56, 95% CI 0.23 to 1.38; 1 study; low-certainty evidence) and third-degree tears (RR 0.13, 95% CI 0.01 to 2.32; 1 study; low-certainty evidence), but the CIs are wide and include the possibility of no effect. No events were reported for fourth-degree tears (low-certainty evidence). Vocalisation may increase maternal satisfaction (RR 1.19, 95% CI 0.93 to 1.51; 1 study; low-certainty evidence). The evidence is very uncertain about the effect of vocalisation on perineal pain (RR 1.44, 95% CI 0.81 to 2.58; 1 study; very low-certainty evidence). Warm compress on the perineum versus control (hands off or no warm compress) Warm compress on the perineum may result in little to no difference in second-degree tears (RR 0.94, 95% CI 0.72 to 1.21; 2 studies; low-certainty evidence), but likely results in a reduction in third- or fourth-degree tears (RR 0.46, 95% CI 0.27 to 0.79; 3 studies; moderate-certainty evidence). Evidence from two smaller studies is very uncertain about the effect of warm compress on the perineum on third-degree tears (RR 0.51, 95% CI 0.04 to 7.05; 2 studies; very low-certainty evidence) or fourth-degree tears (RR 0.11, 95% CI 0.01 to 2.06; 2 studies; very low-certainty evidence) when reported separately. Warm compress likely results in a large reduction in perineal pain (mean difference (MD) -0.81, 95% CI -1.18 to -0.44; 1 study; moderate-certainty evidence). The evidence is very uncertain about the effect of warm compress on the perineum on maternal satisfaction and PPH ≥ 500 mL. Massage of the perineum versus control (hands off or no usual care) Massage of the perineum may have little to no effect on second-degree tears (RR 1.04, 95% CI 0.89 to 1.21; 4 studies; low-certainty evidence). The evidence is very uncertain about the effect of massage of the perineum on third-degree tears (RR 0.57, 95% CI 0.16 to 2.02; 4 studies; very low-certainty evidence). Massage of the perineum may reduce fourth-degree tears but the CIs are wide and include the possibility of no effect (RR 0.26, 95% CI 0.04 to 1.61; 4 studies; low-certainty evidence). The evidence suggests that massage likely results in little to no difference in perineal pain (RR 0.97, 95% CI 0.90, 1.05; 1 study; moderate-certainty evidence). One study reported 10 participants with postpartum haemorrhage across three interventions (warm compress, massage, control). Combined warm compress and massage of the perineum versus control Combined warm compress and massage of the perineum likely results in a reduction in second-degree tears when compared to a control (RR 0.63, 95% CI 0.46 to 0.86; 1 study; moderate-certainty evidence), but the evidence is very uncertain about the effect on third-degree tears (RR 2.92, 95% CI 0.12 to 70.72; 1 study; very low-certainty evidence). The intervention may result in a reduction in PPH ≥ 500 mL but the CIs are wide and include the possibility of no effect (RR 0.43, 95% CI 0.14 to 1.35; 1 study; low-certainty evidence). Combined warm compress and massage likely results in an increase in maternal satisfaction (MD 0.4, 95% CI -0.01 to 0.81; 1 study; moderate-certainty evidence). Combined warm compress and massage of the perineum versus massage alone Combined warm compress and massage of the perineum may result in little to no difference in second-degree tears (RR 0.95, 95% CI 0.86 to 1.06; 1 study; low-certainty evidence) when compared to massage alone, but the evidence is very uncertain about the effect on third- or fourth-degree tears (RR 0.98, 95% CI 0.06 to 15.49; 1 study; very low-certainty evidence). It may also result in little to no difference in PPH ≥ 500 mL (RR 1.10, 95% CI 0.59 to 2.07; 1 study; low-certainty evidence). The evidence suggests that combined warm compress and massage may result in little to no difference in maternal satisfaction (1 study; low-certainty evidence). Other perineal techniques We also assessed evidence on the following comparisons, but since they are used less frequently in global clinical practice to optimise birth outcomes, we have not presented the results summary here: Ritgen's manoeuvre versus standard care; primary delivery of posterior versus anterior shoulder; massage with enriched oil on the perineum versus massage with liquid wax; petroleum jelly on the perineum versus control; and perineal protection device versus control.

AUTHORS' CONCLUSIONS

Overall, the evidence for the effectiveness of perineal techniques to reduce perineal trauma and postpartum haemorrhage is very uncertain. Very few studies reported rates of postpartum haemorrhage, adverse events, women's or health workers' experience or other important outcomes that allow us to understand the effectiveness and acceptability of perineal techniques to reduce perineal trauma. Prior to any further large trials, research is needed to clarify the types of interventions, including a clear description of the process of development and involvement of relevant stakeholders. There is a need to clarify how the intervention is proposed to achieve its effects. Trials would benefit from process evaluation alongside, to explore context, mechanisms and effects.

Could a simple manual technique performed by a midwife reduce the incidence of episiotomy and perineal lacerations? A non-randomized pilot study

INTRODUCTION

Women experience medical interventions, episiotomy, and perineal lacerations during childbirth, impacting their physical, psychological, and sexual well-being. This study compares the perineal status of prospective women who had the midwifery intervention of perineal myofascial release during childbirth, to a matched retrospective control sample of women who received standard care during childbirth.

METHODS

A non-randomized pilot study with prospective data collected for 50 women after informed verbal consent was obtained to having the midwifery intervention of perineal myofascial release during childbirth, and the matched retrospective data for the control group of 49 women were collected from a random sample generated from the medical records. Quantitative analyses included descriptive statistics, independent t-tests, regression, and chi-squared analyses. Retrospective trial registration was granted with The Australian New Zealand Clinical Trials Registry ANZTR.

RESULTS

Women were six times (OR=0.15; 95% CI: 0.0-0.37) less likely to have a non-intact perineum and twice (OR=0.44; 95% CI: 0.35-0.56) less likely to have an episiotomy if they were in the intervention group. Chi-squared analysis found no statistically significant differences between groups for normal vaginal birth and instrumental births, excluding cesareans and waterbirth [χ2(1)= -0.37, p=0.542].

CONCLUSIONS

This study found perineal myofascial release benefits women by reducing perineal trauma and episiotomy. However, there were no significant differences in the duration of the active pushing stage of labor or mode of birth. This study has shown some promise in obtaining data for a larger, definitive, randomized controlled trial.

Effect of an Intrapartum Pelvic Dilator Device on Levator Ani Muscle Avulsion During Primiparous Vaginal Delivery: A Pilot Randomized Controlled Trial

INTRODUCTION AND HYPOTHESIS

The objective was to evaluate the safety and effectiveness of an intrapartum electromechanical pelvic floor dilator designed to reduce the risk of levator ani muscle (LAM) avulsion during vaginal delivery.

METHODS

A multicenter, randomized controlled trial enrolled nulliparous participants planning vaginal delivery. During the first stage of labor, participants were randomized to receive the intravaginal device or standard-of-care labor management. The primary effectiveness endpoint was the presence of full LAM avulsion on transperineal pelvic-floor ultrasound at 3 months. Three urogynecologists performed blinded interpretation of ultrasound images. The primary safety endpoint was adverse events (AEs) through 3 months.

RESULTS

A total of 214 women were randomized to Device (n = 113) or Control (n = 101) arms. Of 113 Device assignees, 82 had a device placed, of whom 68 delivered vaginally. Of 101 Control participants, 85 delivered vaginally. At 3 months, 110 participants, 46 Device subjects who received full device treatment, and 64 Controls underwent ultrasound for the per-protocol analysis. No full LAM avulsions (0.0%) occurred in the Device group versus 7 out of 64 (10.9%) in the Control group (p = 0.040; two-tailed Fisher's test). A single maternal serious AE (laceration) was device related; no neonate serious AEs were device related.

CONCLUSIONS

The pelvic floor dilator device significantly reduced the incidence of complete LAM avulsion in nulliparous individuals undergoing first vaginal childbirth. The dilator demonstrated an acceptable safety profile and was well received by recipients. Use of the intrapartum electromechanical pelvic floor dilator in laboring nulliparous individuals may reduce the rate of LAM avulsion, an injury associated with serious sequelae including pelvic organ prolapse.

Repercussions of perineal repair using surgical glue or suture thread on postpartum outcomes: A controlled randomized clinical trial in São Paulo, Brazil

INTRODUCTION

The type of perineal repair can have significant long-term effects on various functions in a woman's postpartum life. The aim was to compare urinary incontinence (UI), women's satisfaction, pelvic floor muscle strength (PFMS), and sexual function according to the type of perineal repair (surgical glue or suture thread) during the first eight months after normal childbirth.

METHODS

A controlled randomized clinical trial of 133 primiparous women undergoing perineal repair during birth with surgical glue or sutures, evaluated during labor and monitored up to 8 months postpartum, from March 2017 to September 2018, in the city in São Paulo, Bazil. Descriptive and inferential analyses were carried out.

RESULTS

A total of 133 women were included in the study, 111 (83.5%) were assessed between 10 to 20 days postpartum, 121 (91.0%) between 50 to 70 days, and 54 (40.6%) between 6 to 8 months. There were no significant differences for UI concerning the type of repair; however, there was a significant difference concerning the postpartum period (p=0.031), with a higher prevalence at two months. Most women reported satisfaction, with the highest levels reported two months after birth (p=0.019). For PFMS, the mean of the glue and suture groups were 32.4 cmH2O and 27.4 cmH2O, but not significant. Women in the glue group showed higher mean values in all sexual function domains but without significance.

CONCLUSIONS

Surgical glue showed good aesthetic and functional results in the perineum at eight months postpartum.

Antenatal Perineal Training for Injuries Prevention: Follow Up after Puerperium

Background and Objectives: This retrospective analysis investigated the impact of preparation of the pelvic floor for childbirth with stretching balloons and perineal massage on the risk of pelvic floor injuries. Materials and Methods: We analyzed 150 primiparous women who accessed private clinics in Padua (Italy) in the period 2019-2023 regarding the rate of perineal trauma and postpartum dysfunction across three groups: the balloon stretching group (BSG, N = 50, 33.3%), the perineal massage group (PMG, N = 39, 26.0%), and the control group (CG, 61, 40.7%). Results: Prenatal perineal training had a significant impact on reducing the rate of perineal injury and episiotomy (27.5% in BSG vs. 48.7% in PMG and 68.3% in CG, p = 0.008, respectively, 9.8% vs. 26% and 40%, p = 0.046) and the duration of the second stage of labor (BSG and PMG had a shorter duration compared to CG with a mean difference of -0.97892 h, p < 0.001, respectively, -0.63372 h, p = 0.002). Patients who carry out the preparation with the stretching balloon are less likely to develop urinary and anal incontinence and pain during intercourse. Specifically, the rate of urinary incontinence in BSG stands at around 23.5% compared to 43.6% in PMG (p = 0.345) and 55% in CG (p = 0.034). Dyspareunia in BSG was detected in 11.8% of cases compared to 35.5% in PMG (p = 0.035) and 61.7% in CG (p < 0.01). Symptomatology inherent to the posterior compartment was reported in 9.8% of cases in BSG vs. 23.11% in PMG (p = 0.085) and 33.3% in CG (p = 0.03%). Conclusions: Stretching balloons and perineal massage can be chosen as tools to prevent and reduce the rates of obstetric trauma during childbirth and to reduce the use of episiotomies as well as protect against the development of dysfunctions of the pelvic floor.

Prevalence and associated factors of maternal birth trauma following vaginal delivery at University of Gondar Comprehensive Specialized Hospital, North-West Ethiopia, 2022

BACKGROUND

Maternal injury with any form of perineal trauma following vaginal delivery is very common which ranges globally from 16.2 to 90.4%. The frequency of Obstetric anal sphincter Injuries and the incidence of cervical laceration increases rapidly. However, in Ethiopia, there is limited evidence on the prevalence of maternal birth trauma and its determinant factors after vaginal delivery.

OBJECTIVE

To assess the magnitude and associated factors of Maternal Birth Trauma after vaginal delivery at University of Gondar Comprehensive Specialized Hospital, Gondar, North-West Ethiopia, 2022.

METHODS

An Institution based cross-sectional study was conducted among mothers with singleton vaginal delivery at University of Gondar Comprehensive Specialized Hospital from 9th May to 9th August 2022 among 424 study participants. Pre-tested semi-structured questioner was utilized. Epi-Data version 4.6 was used for data entry and exported to SPSS version 25 for data management and analysis. To identify the determinant factors, binary logistic regression model was fitted and variables with p-value < 0.2 were considered for the multivariable binary logistic regression analysis. In the multivariable binary logistic regression analysis, Variables with P-value < 0.05 were considered to have statistical significant association with the outcome variable. The Adjusted Odds Ratio (AOR) with 95% CI was reported to declare the statistical significance and strength of association between Maternal Birth Trauma and independent variables.

RESULTS

A total of 424 mothers who delivered vaginally were included. The mean age of participants was 26.83 years (± 5.220 years). The proportion of birth trauma among mothers after vaginal delivery was47.4% (95%CI: 43.1, 51.7). Of different forms of perineal trauma, First degree tear in 42.8%, OASIs in 1.5% and Cervical laceration in 2.5% study participants. In the multivariable binary logistic regression analysis being primiparous (AOR = 3.00; 95%CI: 1.68, 5.38), Gestational age ≥ 39 weeks at delivery (AOR = 2.96; 95%CI: 1.57, 5.57), heavier birth weight (AOR = 12.3; 95%CI: 7.21, 40.1), bigger head circumference (AOR = 5.45; 95%CI: 2.62, 11.31), operative vaginal delivery (AOR = 6.59; 95%CI: 1.44, 30.03) and delivery without perineum and/or fetal head support (AOR = 6.30; 95%CI: 2.21, 17.94) were significantly associated with the presence of maternal birth trauma.

CONCLUSION AND RECOMMENDATION

Maternal birth trauma following vaginal delivery was relatively high in this study. Prim parity, gestational age beyond 39 weeks at delivery, heavier birth weight, bigger head circumference, operative vaginal delivery and delivery without perineum and/or fetal head supported were factors affecting perineal outcome. The Ministry of Health of Ethiopia should provide regular interventional training as to reduce maternal birth trauma.

Lidocaine spray vs mepivacaine local infiltration for suturing 1st/2nd grade perineal lacerations: a randomised controlled non-inferiority trial

BACKGROUND

Perineal lacerations are a very common complication of post-partum. Usually, the repair of 1st and 2nd-grade lacerations is performed after the administration of local anesthesia. Despite the great relevance of the problem, there are only a few studies about the best choice of local anesthetic to use during suturing. We performed a randomised controlled trial to evaluate the efficacy and safety of the use of a local anesthetic spray during the suturing of perineal lacerations in the post-partum.

METHODS

We compared the spray with the standard technique, which involves the infiltration of lacerated tissues, using the NRS scale. 136 eligible women who had given birth at University Hospital of Udine were enrolled and randomly assigned to receive nebulization of Lidocaine hydrochloride 10% spray (experimental group) or subcutaneous/submucosal infiltration of mepivacaine hydrochloride (control group) during suturing of perineal laceration.

RESULTS

The lacerations included 84 1st-grade perineal traumas (61.7%) and 52 2nd-grade perineal traumas (38.2%). All the procedures were successfully completed without severe complications or serious adverse reactions. There were no statistically significant differences between the two groups in terms of blood losses or total procedure time. Moreover, there were no statistically significant differences in terms of NRS to none of the intervals considered. Regarding the application of the spray in the B group, in 36 cases (52.9%) it was necessary to improve the number of puffs previously supposed to be sufficient (5 puffs). Just in 3 cases, an additional injection was necessary (4.4%).

CONCLUSIONS

Our study demonstrates that lidocaine spray alone can be used as a first line of local anesthetic during the closure of I-II-grade perineal lacerations, as it has comparable efficacy to mepivacaine infiltration.

TRIAL REGISTRATION

Care bundles for women during pregnancy, labour/birth, and postpartum: a scoping review

Background

Care bundles, introduced in 2001, are described as a set of at least three evidence-based healthcare interventions delivered together in a clinical care episode by all healthcare providers. Although widely implemented in some healthcare areas, care bundle use in maternity care appears relatively recent. To identify the types of care bundles that have been developed, evaluated, or implemented for women during the perinatal period, we undertook a scoping review.

Methods

Joanna Briggs Institute methodological guidance for scoping reviews was used. MEDLINE, CINAHL, Embase, Maternity and Infant Care, and Epistemonikos were searched from January 2000 to October 2023. Records that reported on women during pregnancy and up to six-weeks postpartum as the intended or actual recipients of a care bundle, were included. The concept of interest was development, evaluation, or implementation of a care bundle. The context was maternity care provision, in any setting or geographical location.

Results

The search yielded 147 eligible records of which 69 originated in the USA. Most records were concerned with care bundle evaluation (n=74), and most were published in the last five-years (n=95). Eleven categories of clinical conditions were identified. These were surgical site infection, obstetric haemorrhage, perineal trauma, sepsis, stillbirth, hypertension, safe reduction of caesarean section, enhanced recovery after caesarean, placenta accrete, perinatal anxiety/depression, and 'other' which contained 21 records reporting on care bundles for one clinical condition. Few clinical conditions had good overlap of care bundle elements. Systematic reviews based on data from non-randomised studies may be feasible for some clinical conditions.

Conclusions

This scoping review provides comprehensive insight on care bundles in maternity care. Few studies were found that evaluated the effectiveness of these bundles, and many bundles for similar clinical conditions contained diverse elements. A more global approach to care bundle development, evaluation, and implementation in maternity care is recommended.

Midwives' practices on perineal protection and episiotomy decision-making: A qualitative and descriptive study

INTRODUCTION

Perineal trauma is associated with both short- and long-term morbidity which in turn relates to the degree of trauma. The objective of this study was to understand midwives' practices regarding perineal protection during the second phase of labor, emphasizing decision-making to perform an episiotomy.

METHODS

A descriptive and explanatory study was conducted with an intentional sample of twenty-two midwives working in the labor ward of a tertiary hospital in a metropolitan location and in the public service, in Portugal. A semi-open interview was applied to collect the data from 5 to 15 January 2019. The computer software package, NVivo version 10, was used to perform the thematic analysis.

RESULTS

Four main themes arose from the midwives' data: 1) Factors affecting the application of perineal protection techniques', 2) Birth position, 3) Techniques for perineal protection, and 4) Episiotomy. The reasons for performing an episiotomy were the presence of tense perineum, large weight baby, previous obstetric anal sphincter injury, and Kristeller maneuver.

CONCLUSIONS

Midwives' practices regarding perineal protection techniques and reasons for performing an episiotomy were not all in line with the evidence. Perineal massage was not mentioned as a perineal protection technique.

Development of aids to relieve vulvodynia during the postpartum period

Postpartum women live with a low quality of life due to pain caused by episiotomy and perineal laceration. In particular, they endure pain when sitting for long periods of time to breastfeed. The purpose of this study is to develop a sitting aid to alleviate postpartum vulvodynia. This study was conducted in the following four phases from July 2017 to May 2019. They are: material selection and molding, cleaning and disinfection testing, pressure distribution measurement testing, and trial testing by postpartum women. The main material was a 100% polypropylene object with a three-dimensional reticular fiber spring structure and fiber density of 3.8 kg/m2. As a result, a sitting aid that withstands washing and disinfection well in the medical field and is breathable. It had moderate resilience and elasticity and reduced pressure on the seating surface for women weighing approximately 45 kg and 55 kg, but we were skeptical about its use for women weighing more than that. The completed sitting aid is noninvasively effective in improving the quality of life of many postpartum women, but the density and thickness of the main material should be reexamined to meet the needs of women in a wider weight range. In addition, a self-administered questionnaire survey of trial users revealed that some women did not experience relief from vulvodynia even after using the sitting aid. Such women also had physical problems such as discomfort in the lower back, difficulty breastfeeding, and difficulty standing up. For women with multiple physical problems, individual causes should be addressed.

Midwives' approach to the prevention and repair of obstetric perineal trauma in Spain

AIM

Different clinical practice guidelines include recommendations on how to prevent and repair obstetric perineal trauma, as well as the use of episiotomy. To evaluate the variability in midwives' professional practices for preventing and repairing perineal trauma, as well as the professional factors that may be associated with the restrictive use of episiotomy.

DESIGN

Observational cross-sectional study.

METHODS

Three hundred five midwives completed an anonymous questionnaire developed by the authors and distributed across various midwifery scientific societies. The main outcomes measured were the frequencies of adopting specific practices related to perineal injury prevention and repair, episiotomy technique and restrictive episiotomy use (<10%). Odds ratios (OR) and adjusted odds ratios (aOR) with 95% confidence intervals were estimated.

RESULTS

Intrapartum perineal massage was not normally used by 253 (83%) of midwives, and 186 (61%) applied compresses soaked in warm water to the perineum. Regarding episiotomy, there was a great deal of variability, noting that 129 (42.3%) adopted a restrictive use of this procedure, 125 (41%) performed it between 10% and 20%, while 51 midwives (16.7%) performed it in more than 20% of cases. In addition, 165 (54.1%) midwives followed an incision angle of 60º. Concerning tears, 155 (50.8%) usually sutured first-degree tears and 273 (89.5%) always sutured second-degree tears. Midwives attending home births (aOR = 6.5; 95% CI: 2.69-15.69), working at a teaching hospital (aOR = 3.69; 95% CI: 1.39-9.84), and the ones who recently completed their professional training (aOR = 3.58; 95% CI: 1.46-8.79) were significantly more likely to adopt a restrictive use of episiotomy.

CONCLUSIONS

There is a significant variability in Spanish midwives' practices for preventing and repairing perineal tears. Moreover, the restrictive use of episiotomy is associated with midwives attending home births, working in teaching hospitals and having recent professional training.

Effect of Perineal Massage and Warm Compresses Technique in Postpartum Pelvic Floor Dysfunction. A Secondary Analysis from a Randomised Controlled Trial

Pelvic floor dysfunction (PFD) is common to be associated with pregnancy and birth. To date, no research has been done to understand whether the perineal massage and warm compresses technique has an impact on pelvic floor dysfunction. To assess the impact of perineal massage and warm compresses technique during the second stage of labor in pelvic floor dysfunction at 3 and 6 months postpartum. Of the 800 women recruited to randomised controlled trial to prevent perineal trauma, 496 were included in the study, with 242 (48.8%) assigned to the Perineal Massage and Warm Compresses (PeMWaC) group and 254 (51.2%) to the control group (hands-on). Used the Pelvic Floor Distress Inventory-20 (PFDI-20). The questionnaire is divided into three subscales: Urinary (UDI), Colorectal-Anal (CRADI), and Pelvic Organ Prolapse Distress Inventory (POPDI). The PeMWaC group had a significantly higher frequency of intact perineum (p < 0.001) and low-severity vaginal tears (tears without any other degree of perineal trauma) (p = 0.031) compared to the control group, while the control group had significantly more patients who suffered high-severity vaginal/perineal trauma (second degree perineal tears) (p = 0.031) and patients without spontaneous perineal trauma or vaginal tears who underwent episiotomy (p < 0.001). In addition, at 3 months postpartum, women in the control group had a higher Urinary Distress Inventory (UDI) score and global score, compared to the PeMWaC group, and after controlling for confounding variables, the perineal massage and warm compresses technique was associated with lower UDI scores at 3 months postpartum compared to control group. At 6 months postpartum, there were no differences in the UDI or global scores, indicating general recovery from perineal trauma. In addition to reducing perineal trauma during birth, the perineal massage and warm compresses technique was associated with a lower prevalence of early PFD symptoms, mainly urinary distress, at 3 months.Trial registration http://www.ClinicalTrials.gov NCT05854888, retrospectively registered.

Obstetric outcomes and uptake of care among 149 non-Swedish speaking migrant women attending a birth preparation visit during pregnancy - An observational study from Sweden

Introduction

In Sweden almost one third of the population is born in another country and a large number of the women who do not speak Swedish are of reproductive age. Women migrating from low-income countries have higher risks for poor obstetric outcomes than receiving country-born citizens. INFOR (a Swedish word for "before" or "ahead of") is an intervention offering language-assisted, individual birth preparation for non-Swedish speaking pregnant women unfamiliar with the maternity care system. The aim of this study was to describe the uptake of care and obstetric outcomes among non-Swedish speaking migrant women attending INFOR.

Methods

A descriptive study of the obstetric outcomes and uptake of care was conducted of the 149 non-Swedish speaking pregnant women who participated in INFOR between 2016 and 2020. The data were accessed retrospectively from the medical record system Obstetrix and the population-based Swedish Pregnancy Registry and analysed descriptively.

Results

Women participating in INFOR originated from 44 countries and spoke 35 different languages. During late pregnancy, 20 percent of the women sought care for decreased fetal movements and 80 percent of the women attended the postpartum visit. While the majority of the participants were offered professional language support during pregnancy, almost none had a professional interpreter present during labour and birth. After birth, 80 percent of the primiparous women were asked to rate their birth experience, but only half of the multiparous women were asked. Further, only half of the primiparous women attending the postpartum visit were asked about their self-rated health.

Conclusion

INFOR may increase uptake of some important aspects of care during pregnancy, birth and postpartum among migrants of diverse backgrounds. The findings raise concerns however about communication support for migrant women, especially during labour and birth. The offer of professional interpreting as part of standard maternity care for women who need it is essential and must be improved in order to provide equitable care for all.

Variability of clinical practice in the care of the second stage of labor among midwives in Spain

BACKGROUND

There are recommendations based on scientific evidence on care in the second stage of labor, but it is not known to what degree the professionals comply with these recommendations.

OBJECTIVE

The aim of this study is to examine the variability in clinical practices among midwives during the second stage of labor, including positions, mobility, practices, and the maximum time allowed before initiating active pushing, and to assess their adherence to clinical practice guidelines.

METHODS

A cross-sectional observational study. A self-designed questionnaire was developed and distributed online through scientific societies. The main variables studied were professional and work environment characteristics, maternal positions and mobility, practices during this stage, maximum time to start active pushing and duration of the second stage of labor. Descriptive statistics were calculated using SPSS 24.0.

RESULTS

Regarding the woman's position during childbirth, 80.3% (245) of midwives frequently or always allow the woman to choose her birthing position. Furthermore, 44.6% (136) of professionals prefer using side-lying positions for the mother. Regarding drinking fluids during childbirth, 51.1% (156) of midwives allowed the woman to drink the amount of liquids she wanted, whereas 11.1% (34) said that they would allow them to do so however, this was against the protocol of their hospital. When inquiring about the Kristeller maneuver, it was reported to be excessively performed in 35.1% (107) of cases for fetal bradycardia, 33.1% (101) for maternal exhaustion, and 38.4% (117) to avoid instrumental birth. Finally, a great variability was observed in the time criteria used for the initiation of active pushing and the maximum duration of the second stage of labor.

CONCLUSIONS

Certain practices, such as the Kristeller maneuver, are overused among midwives, with great variability in the use of certain procedures, the waiting times to initiate pushing and completion of the second stage of labor. Further training and awareness campaigns are needed for professionals to apply evidence-based care.

Effects of Perineal Warm Compresses during the Second Stage of Labor on Reducing Perineal Trauma and Relieving Postpartum Perineal Pain in Primiparous Women: A Systematic Review and Meta-Analyses

Non-pharmaceutical midwifery techniques, including perineal warm compresses, to improve maternal outcomes remain controversial. The aims of this study are to assess the effects of perineal warm compresses on reducing perineal trauma and postpartum perineal pain relief. This systematic review included randomized controlled trials (RCTs). We searched seven bibliographic databases, three RCT register websites, and two dissertation databases for publications from inception to 15 March 2023. Chinese and English publications were included. Two independent reviewers conducted the risk of bias assessment, data extraction, and the evaluation of the certainty of the evidence utilizing the Cochrane risk of bias 2.0 assessment criteria, the Review Manager 5.4, and the online GRADEpro tool, respectively. Seven RCTs involving 1362 primiparous women were included. The combined results demonstrated a statistically significant reduction in the second-, third- and/or fourth- degree perineal lacerations, the incidence of episiotomy, and the relief of the short-term perineal pain postpartum (within two days). There was a potential favorable effect on improving the integrity of the perineum. However, the results did not show a statistically significant supportive effect on reducing first-degree perineal lacerations and the rate of perineal lacerations requiring sutures. In summary, perineal warm compresses effectively reduced the second-, third-/or fourth-degree perineal trauma and decreased the short-term perineal pain after birth.

The effects of warm perineal compress on perineal trauma and postpartum pain: a systematic review with meta-analysis and trial sequential analysis

BACKGROUND

In order to reduce the complications of perineal damage and the pain caused by it for the mother, this study was conducted to determine the effect of warm perineal compress on perineal trauma (1st-, 2nd-, 3rd-, and 4th-degree perineal tears), postpartum pain, intact perineum (primary outcomes), episiotomy, length of the second stage, and APGAR score at 1 and 5 min after childbirth (secondary outcome).

METHODS

PubMed, Scopus, Cochrane Central Register of Controlled Trials, Google Scholar, Web of Science, SID, Magiran, and ClinicalTrials.gov were searched to identify the relevant articles from inception to November 1, 2022, with language restriction (only English and Persian). A manual search was also performed. Risk of bias 2 (RoB2) and ROBIN-I were employed to evaluate the quality of the included papers. Meta-analysis was conducted using RevMan 5.3. Heterogeneity was assessed using I2. In cases with high heterogeneity, subgroup analysis was utilized based on the parity and ethnicity, and time of pain measurement after delivery also a random-effects model was used instead of a fixed-effects model. Trial sequential analysis (TSA) was performed for the primary outcomes. The certainty of evidence was assessed using the GRADE approach.

RESULTS

A total number of 228 articles were found in databases. Of these articles, eighty-six were screened by title, 27 by abstract, and 21 by full text. Finally, 14 articles were included, of which ten were RCT and four were non-RCT. Meta-analysis results revealed that warm perineal compress significantly reduced perineal pain (RR 0.23, 95% CI 0.08-0.66; P = 0.0006), average pain (SMD - 0.73, 95% CI 1.23 to - 0.23; P = 0.004), second-degree perineal tear (RR 0.65, 95% CI 0.54-0.79; P˂0.00001), third-degree perineal tear (RR 0.32, 95% CI 0.15-0.67; P = 0.003), fourth-degree perineal tear (RR 0.11, 95% CI 0.01-0.87; P = 0.04), episiotomy (RR 0.63, 95% CI 0.46-0.86; P = 0.004), and intact perineum significantly increased (RR 3.06, 95% CI 1.79-5.22; P < 0.0001) compared to the control group. However, there was no statistically significant difference in terms of first-degree tear (RR 1.04, 95% CI 0.86-1.25; P = 0.72), length of the second stage of labor (MD - 0.60, 95% CI - 2.43 to 1.22; P = 0.52), the first minute (MD - 0.03, 95% CI - 0.07 to 0.02; P = 0.24) and the fifth minute Apgar score (MD - 0.02, 95% CI - 0.07 to 0.03; P = 0.46) between the two groups.

CONCLUSION

Warm perineal compress administered during the second stage of labor reduce postpartum pain, second and third-degree perineal tears, and episiotomy rate while it increases the incidence of intact perineum compared to the control group.

Is water delivery a good idea to prevent obstetric anal sphincter injuries in low risk primiparae? An exploratory study in a Swiss public teaching hospital

OBJECTIVE

Obstetric anal sphincter injuries are feared perineal injuries that are associated with increased pelvic floor disorders. The knowledge of influencing factors as the mode of delivery is therefore important. The aim of this study is to compare the rate of obstetric anal sphincter injuries in primiparae after water and bed deliveries.

STUDY DESIGN

In this retrospective cohort study 3907 primiparae gave birth in water or on a bed in a Swiss teaching hospital. The diagnosis of obstetric anal sphincter injuries was confirmed by a consultant of obstetrics and gynecology and treated by them. The rates of these injuries after water and bed births were compared. Subgroup analysis was performed to detect possible associative factors, such as birth weight, episiotomy, use of oxytocin in first and second stage of labor.

RESULTS

1844 (47.2 %) of the primiparae had a water delivery and 2063 (52.8 %) a bed delivery. 193 (4.94 %) were diagnosed with obstetric anal sphincter injuries, of which 68 (3.7 %) had a water delivery and 125 (6.1 %) a bed delivery, p < 0.001. Subgroup analysis revealed that, in the first and second stage of labor, the rate of obstetric anal sphincter injuries with oxytocin was significantly lower in water than in bed deliveries; p = 0.025, p < 0.017, respectively. The rate of obstetric anal sphincter injuries in the birth weight or episiotomy subgroups did not reach significance.

CONCLUSIONS

In a teaching hospital setting with standardized labor management, primiparae with a water delivery have the lowest risk for obstetric anal sphincter injuries.

Factors associated with perineal pain on the first postnatal day after vaginal delivery: a cross-sectional study of primiparous women

Many women report postpartum perineal pain due to perineal trauma after vaginal delivery. Perineal pain after giving birth declines over time; however, perineal trauma and pain negatively impact on the women's quality of life and their ability to care for their children. The degree of perineal trauma and instrument delivery with episiotomy are associated with perineal pain. Nevertheless, no studies have examined factors related to postpartum perineal pain, including weight changes during pregnancy as well as the course of delivery so far. We aimed to elucidate obstetric factors associated with perineal pain after vaginal delivery on the first postnatal day in Japanese primiparous women. A cross-sectional study conducted in five maternity hospitals in Japan included 142 primiparous women who vaginally delivered full-term and singleton infants. Perineal pain on the first postnatal day was evaluated using a visual analog scale. The final analysis included 92 participants with a mean age of 30.3 ± 4.6 years. The median visual analog scale score was 54.0 mm. Multiple linear regression analysis demonstrated that gestational weight gain above the recommended Japanese range was positively and significantly associated with perineal pain on the first postnatal day, independent of maternal age, episiotomy, painkiller use, and neonatal birth weight. This finding may provide additional evidence regarding gestational weight gain within the recommended range based on the pre-pregnancy body mass index to reduce perineal pain on the first postnatal day.

Pregnancy, parturition and postpartum considerations among patients with vulvar lichen sclerosus: A retrospective cross-sectional online survey

OBJECTIVE

Characterise VLS and obstetric considerations among women during pregnancy, parturition and postpartum.

DESIGN

Retrospective cross-sectional online survey, 2022.

SETTING

International, English-speakers.

POPULATION

Self-identified individuals aged 18-50 diagnosed with VLS with symptom onset prior to pregnancy.

METHODS

Participants recruited from social media support groups and accounts, completed a 47-question survey including yes/no, multiple answer, and free-text responses. Data were analysed with frequency, means and the Chi-square test.

MAIN OUTCOME MEASURES

VLS symptom severity, mode of delivery, perineal laceration, source and sufficiency of information provided about VLS and obstetrics, anxiety about delivery, and postpartum depression.

RESULTS

Of 204 responses, 134 met inclusion criteria, encompassing 206 pregnancies. Mean respondent age was 35 years (SD 6) and mean age of VLS symptom onset, diagnosis and birth, was 22 (SD 8), 29 (SD 7) and 31 (SD 4) years, respectively. Symptoms decreased in 44% (n = 91) of pregnancies and increased during the postpartum period in 60% (n = 123). In all, 67% (n = 137) of pregnancies resulted in vaginal birth and 33% (n = 69) in caesarean birth. Anxiety for delivery due to VLS symptoms was reported by 50% (n = 103); 31% (n = 63) experienced postpartum depression. Of respondents previously diagnosed with VLS, 60% (n = 69) used topical steroids prior to pregnancy, 40% (n = 45) were treated during pregnancy and 65% (n = 75) postpartum. In all, 94% (n = 116) reported receiving an insufficient amount of information on the topic.

CONCLUSION

In this online survey, we found reported symptom severity remained unchanged or decreased during pregnancy, but increased postpartum. Use of topical corticosteroids decreased during pregnancy compared with before and after pregnancy. Half of the respondents reported anxiety regarding VLS and delivery.

Shifting Trends in Obstetrics: An 18-year Analysis of Low-risk Births at a German University Hospital

BACKGROUND/AIM

At the beginning of the 21st century, obstetric medicine took a turn from interventional to restrictive in low-risk birth. The present study examined the changes in peripartum management over the past 20 years at the Women's University Hospital Cologne. The attitudes of the becoming mother and physicians towards anesthesia, episiotomy, and vaginal-operative deliveries were compared and the factors influencing the duration of birth over the past 20 years were examined.

PATIENTS AND METHODS

In this retrospective study, the low-risk singleton birth of 955 in 2000/2001 and 944 births in 2018 at the Women's University Hospital Cologne were analyzed.

RESULTS

The age of women who tended to give birth has significantly increased at present compared to 20 years ago. In 2018, labor was induced significantly more often than in 2000/2001. The rate of vaginal operative deliveries has fluctuated between 15% and 20% in the last 20 years. Forceps are no longer used. The use of episiotomy has taken a fundamental turn in the last 20 years. Prophylactic episiotomy is not performed anymore, most vaginal operative deliveries take place without the episiotomy. The birth duration has been significantly shortened at present compared to 20 years ago.

CONCLUSION

Pregnancy and childbirth over the last years are not considered as a disease, but as a natural course, and the trend of minimizing interventions in low-risk delivery has a positive effect on childbirth.

Primary midwives' experiences of collegial midwifery assistance during the active second stage of labor: Data from the Oneplus trial

BACKGROUND

Collegial midwifery assistance during the active second stage of labor that involves a second midwife being present has been shown to reduce severe perineal trauma (SPT) by 30%. The aim of this study was to investigate primary midwives' experiences of collegial midwifery assistance with the purpose of preventing SPT during the active second stage of labor.

METHODS

This study uses an observational design with data from a multicenter randomized controlled trial (Oneplus). Data consist of clinical registration forms completed by the midwives after birth. Descriptive statistics as well as univariable and multivariable logistic regression were used to analyze the data.

RESULTS

The majority of the primary midwives felt confident (61%) and were positive (56%) toward the practice. Midwives with less than 2 years' work experience were more likely to completely agree they felt confident (aOR 9.18, 95% CI: 6.28-13.41) and experience the intervention as positive (aOR 4.04, 95% CI: 2.83-5.78) than those with over 20 years' work experience. Factors such as duration of time spent in the birthing room by the second midwife, opportunity for planning and if the second midwife provided support were further associated with the primary midwife's experience of the practice as being positive.

CONCLUSIONS

Our findings indicate that having a second midwife present during the active second stage of labor was an accepted practice, with the majority of primary midwives feeling confident and positive toward the intervention. This was especially pronounced among midwives with less than 2 years' work experience.

Incidence of obstetric anal sphincter injuries following breech compared to cephalic vaginal births

INTRODUCTION

Obstetric anal sphincter injuries (OASIs) at the time of childbirth can lead to serious consequences including anal incontinence, dyspareunia, pain and rectovaginal fistula. These types of lesions and their incidence have been well studied after cephalic presentation deliveries, but no publications have specifically addressed this issue in the context of vaginal breech delivery. The goal of our study was to evaluate the incidence of OASIs following breech deliveries and compare it with cephalic presentation births.

METHODS

This was a retrospective cohort study involving 670 women. Of these, 224 and 446 had a vaginal birth of a fetus in the breech (breech group) and cephalic (cephalic group) presentations respectively. Both groups were matched for birthweight (± 200 g), date of delivery (± 2 years) and vaginal parity. Main outcome of interest was to evaluate the incidence of OASIs following breech vaginal birth compared to cephalic vaginal births. Secondary endpoints were the incidence of intact perineum or first-degree tear, second-degree perineal tear and rates of episiotomies in each group.

RESULTS

There was no statistically significant difference in OASIs incidence between the breech and cephalic groups (0.9% vs. 1.1%; RR 0.802 (0.157; 4.101); p = 0.31). There were more episiotomies in the breech group (12.5% vs. 5.4%, p = 0.0012) and the rate of intact or first-degree perineum was similar in both groups (74.1% vs. 75.3%, p = 0.7291). A sub-analysis excluding patients with episiotomy and history of OASIs did not show any statistically significant difference either.

CONCLUSION

We did not demonstrate a significant difference in the incidence of obstetric anal sphincter injuries between women who had a breech vaginal birth compared to cephalic.

Term breech presentation vaginal births in Tibet: A retrospective analysis of 451 cases

Background

In high altitude areas, like Tibet, most fetuses in breech presentation at term are delivered vaginally owing to a variety of reasons, but this has not been published.

Objective

This study aimed to provide references and evidence for the delivery of breach presentation term fetuses in high altitude areas, through comparing and analyzing the data of full-term singleton fetuses with breech or cephalic presentation in Naqu People's Hospital, Tibet.

Study design

We retrospectively analyzed the clinical data of 451 breech presentation fetuses mentioned above over a period of 5  years (2016-2020). A total of 526 cephalic presentation fetuses' data within 3  months (1 June to 1 September 2020) of the same period were collected too. Statistics were compared and assembled on fetal mortality, Apgar scores, and severe neonatal complications for both planned cesarean section (CS) and vaginal delivery. In addition, we also analyzed the types of breech presentation, the second stage of labor, and damage to the maternal perineum during vaginal delivery.

Results

Among the 451 cases of breech presentation fetuses, 22 cases (4.9%) elected for CS and 429 cases (95.1%) elected for vaginal delivery. Of the women who chose vaginal trial labor, 17 cases underwent emergency CSs. The perinatal and neonatal mortality rate was 4.2% in the planned vaginal delivery group and the incidence of severe neonatal complications was 11.7% in the transvaginal group, no deaths were detected in the CS group. Among the 526 cephalic control groups with planned vaginal delivery, the perinatal and neonatal mortality was 1.5% (p = 0.012), and the incidence of severe neonatal complications was 1.9%. Among vaginal breech deliveries, most of them were complete breech presentation (61.17%). Among the 364 cases, the proportion of intact perinea was 45.1%, and first degree lacerations accounted for 40.7%.

Conclusion

In the Tibetan Plateau region, vaginal delivery was less safe than cephalic presentation fetuses for full-term breech presentation fetuses delivered in the lithotomy position. However, if dystocia or fetal distress can be identified in time and then encouraged to convert to cesarean, its safety will be greatly improved.

"Dispatcher, Can You Help Me? A Woman Is Giving Birth". A Pilot Study of Remote Video Assistance with Smart Glasses

Smart glasses (SG) could be a breakthrough in emergency situations, so the aim of this work was to assess the potential benefits of teleassistance with smart glasses (SG) from a midwife to a lifeguard in a simulated, unplanned, out-of-hospital birth (OHB). Thirty-eight lifeguards were randomized into SG and control (CG) groups. All participants were required to act in a simulated imminent childbirth with a maternal−fetal simulator (PROMPT Flex, Laerdal, Norway). The CG acted autonomously, while the SG group was video-assisted by a midwife through SG (Vuzix Blade, New York, NY, USA). The video assistance was based on the OHB protocol, speaking and receiving images on the SG. The performance time, compliance with the protocol steps, and perceived performance with the SG were evaluated. The midwife’s video assistance with SG allowed 35% of the SG participants to perform the complete OHB protocol. No CG participant was able to perform it (p = 0.005). All OHB protocol variables were significantly better in the SG group than in the CG (p < 0.05). Telemedicine through video assistance with SG is feasible so that a lifeguard with no knowledge of childbirth care can act according to the recommendations in a simulated, unplanned, uncomplicated OHB. Communication with the midwife by speaking and sending images to the SG is perceived as an important benefit to the performance.

Time trends in episiotomy and severe perineal tears in Portugal: a nationwide register-based study

INTRODUCTION

Rates of episiotomy and severe perineal tears (SPT) are indicators of the quality of obstetric care. Time-trends in the reported occurrence of episiotomy and SPT can contribute to understand both, changes in care and in the frequency of risk factors. Therefore, we aimed to estimate time trends in the frequency of SPT in Portugal and its relationship with episiotomy.

METHODS

We conducted a nationwide register-based study using data from the national inpatient database of all Portuguese public hospitals between 2000 and 2015. Time-trend analysis using joinpoint regression models was performed to identify trends (joinpoints) and compare time changes in the prevalence of SPT and risk factors expressed as annual percentage changes (APC) with 95% Confidence Intervals (95% CI). Poisson regression models were fitted to estimate whether time-trends in SPT rates were explained by changes in risk factors and to assess the association between episiotomy and SPT. Adjusted relative risk (aRR) and their respective 95% CI were obtained.

RESULTS

From 908,999 singleton vaginal deliveries, 20.6% were instrumental deliveries, 76.7% with episiotomy and 0.56% were complicated by SPT. Among women with non-instrumental deliveries and no episiotomy SPT decreased from 2009 onwards (1.3% to 0.7%), whereas SPT kept increasing in women with episiotomy for both non-instrumental (0.1% in 2000 to 0.4% in 2015) and instrumental deliveries (0.7% in 2005 to 2.3% in 2015). Time-trends in potential risk factors did not explain the observed increase in SPT. Episiotomy was associated with a decrease in SPT with adjusted RR varying between 2000 and 2015 from 0.18 (95%CI:0.13-0.25) to 0.59 (95%CI:0.44-0.79) for non-instrumental deliveries and from 0.45 (95%CI:0.25-0.81) to 0.50 (95%CI:0.40-0.72) for instrumental deliveries.

CONCLUSIONS

Our findings suggest that episiotomy rate could safely further decrease as the main factor driving SPT rates seems to be an increase in awareness and reporting of SPT particularly among women who underwent an episiotomy.

Vaginal Birth at Term - Part 2. Guideline of the DGGG, OEGGG and SGGG (S3-Level, AWMF Registry No. 015/083, December 2020)

Purpose This guideline aims to summarize the current state of knowledge about vaginal birth at term. The guideline focuses on definitions of the physiological stages of labor as well as differentiating between various pathological developments and conditions. It also assesses the need for intervention and the options to avoid interventions. The second part of this guideline presents recommendations and statements on care during the dilation and expulsion stages as well as during the placental/postnatal stage. Methods The German recommendations largely reproduce the recommendations of the National Institute for Health and Care Excellence (NICE) CG190 guideline "Intrapartum care for healthy women and babies". Other international guidelines were also consulted in individual cases when compiling this guideline. In addition, a systematic search and analysis of the literature was carried out using PICO questions where necessary, and other systematic reviews and individual studies were taken into account. For easier comprehension, the assessment tools of the Scottish Intercollegiate Guidelines Network (SIGN) were used to evaluate the quality of additionally consulted studies. Otherwise, the GRADE system was used for the NICE guideline, and the evidence reports of the IQWiG were used to evaluate the quality of the evidence. Recommendations Recommendations and statements were formulated based on identified evidence and/or a structured consensus.

Quality aspects relating to giving birth in Switzerland: An analysis of quality indicators in inpatient obstetrics from 2013 to 2017

Quality transparency supports the reduction of information asymmetries in the health care system and enables the targeted regulation of health care. This study examines quality variation in inpatient obstetric care using the official Federal Office of Public Health Inpatient Quality Indicators (CH-IQI; vaginal births with 3rd- and 4th-degree perineal tears, vaginal births with episiotomy, and Caesarean section for low-risk births). It includes 101 maternity hospitals and 425,810 births between 2013 and 2017. For births with perineal laceration of 3rd and 4th degree, Switzerland performs 0.9% poorer in comparison to Germany (D-IQI) and Austria (A-IQI). For births with episiotomy, Switzerland is 1.1% above Germany. The Caesarean section rate for low-risk births was 26.8% in Switzerland in 2017 (Germany: 25.9%). When comparing Swiss clinics, private clinic locations in particular stand out. One possible reason for this may be the density of care, patient demands or the system of affiliated physicians at these clinics.

Magnitude of episiotomy practice and associated factors among women who gave birth at Hiwot Fana Specialized University Hospital, Eastern Ethiopia

BACKGROUND

Episiotomy is an intentional surgical incision made on the perineum with the aim of enlarging the introits during the second stage of labor or just before delivery of the baby. It sometimes also interferes with the mother's comfort during the postpartum period and has associated complications especially when it is done without indication. However, there is limited information regarding episiotomy practice in the study area.

OBJECTIVE

This study aimed to determine the magnitude of episiotomy practice and associated factors among women who gave birth at the Hiwot Fana Specialized University Hospital, Eastern Ethiopia, 2021.

METHODS

A facility-based cross-sectional study was conducted among 408 systematically selected mothers who gave birth at the Hiwot Fana Specialized University Hospital, from 1 January to 30 December 2021. Datas were collected from delivery medical records using a pretested checklist. The extracted data were checked, coded, and entered into the Epi-data version 3.1 and exported to the STATA version 16 software for analysis. Binary logistic regression was fitted to identify factors associated with episiotomy practice. P-values < 0.05 were considered to declare the presence of statistical significance.

RESULTS

The overall prevalence of episiotomy practice was found to be 43.4 % (95% CI: 38.7, 48.9), and mediolateral was the most commonly practiced episiotomy type (41.4%). Parity [AOR: 6.2; 95% CI (3.8-17.6)], 1st min Apgar score [AOR: 1.6; 95% CI (1.04-2.67)], presence of maternal medical disease [AOR: 3.3; 95% CI (1.09-6.9)], and induced labor [AOR: 1.6; 95%CI (1.12, 4.13)] were significantly associated with the episiotomy practice.

CONCLUSION

The prevalence of episiotomy practice in the study area was high. Parity, presence of maternal medical disease, induction of labor, and 1st min APGAR score were significant factors associated with episiotomy practice. Considering the presence of appropriate indications or preventing unjustifiable indications, can help to reduce the current high practice rates.

Perineal Massage for Prevention of Perineal Trauma and Episiotomy During Labor: A Systematic Review and Meta-Analysis

Objective: Vaginal births are associated with a certain degree of trauma to the genital tract, with significant short-term and long-term morbidity. Awareness of morbidity following perineal trauma has led to application of different interventions during the late first stage and second stage of labour to prevent severe perineal trauma. This includes techniques such as perineal massage, warm and cold compresses, and perineal management techniques. Objective of this meta-analysis is to evaluate the effect of perineal massage during the late first stage and second stage of labour on the rate of episiotomy and risk of perineal trauma. Materials and methods: Electronic databases (PubMed, Scopus, Cochrane Library and Science Direct) were searched from inception until August 2021. We included randomized controlled trials (RCTs) which compares perineal massage during labor (i.e., intervention group) with a control group in women with singleton gestation and cephalic presentation at ≥36 weeks. The primary outcome was severe perineal trauma and the rate of episiotomy. Meta-analysis was performed using the random-effects model of DerSimonian and Laird to produce summary treatment effects in terms of relative risk (RR) with 95% confidence interval (CI). Results: Ten trials including 4,088 women were analyzed. Women with perineal massage during labor had a significantly lower incidence of severe perineal trauma (RR: 0.52, 95% CI 0.29- 0.94) compared to the control group. The incidence of episiotomy was lower in the perineal massage group (RR: 0.71, 95% CI 0.52-0.98 p < 0.01) but was statistically insignificant (P>0.05). Conclusion: The finding of meta-analysis showed that perineal massage during labor could be effective in reducing the risk of severe perineal trauma, such as third- and fourth-degree spontaneous lacerations during labor.

Obstetric anal sphincter injuries (OASIS): using transperineal ultrasound (TPUS) for detecting, visualizing and monitoring the healing process

Purpose

The aim of this study was to examine whether OASIS, and its extent, can be confirmed or excluded using transperineal ultrasound (TPUS). A further objective of this study was to monitor the healing process over a period of 6 months and to establish a connection between the sonographic appearance of obstetric anal sphincter injury (OASIS) and anal incontinence.

Materials and methods

In this retrospective clinical study, women with OASIS who gave birth between March 2014 and August 2019 were enrolled. All the patients underwent TPUS 3 days and 6 months after delivery. A GE E8 Voluson ultrasound system with a 3.5–5 MHz ultrasound probe was used. The ultrasound images showed a third-degree injury, with the measurement of the width of the tear and its extent (superficial, partial, complete, EAS and IAS involvement). A positive contraction effect, a sign of sufficient contraction, was documented. Six months after delivery, a sonographic assessment of the healing (healed, scar or still fully present) was performed. A Wexner score was obtained from each patient. The patients’ medical histories, including age, parity, episiotomy and child’s weight, were added.

Results

Thirty-one of the 55 recruited patients were included in the statistical evaluation. Three patients were excluded from the statistical evaluation because OASIS was excluded on TPUS 3 days after delivery. One patient underwent revision surgery for anal incontinence and an inadequately repaired anal sphincter injury, as shown sonographic assessment, 9 days after delivery. Twenty patients were excluded for other reasons. The results suggest that a tear that appears smaller (in mm) after 3 days implies better healing after 6 months. This effect was statistically significant, with a significance level of alpha = 5% (p = 0.0328). Regarding anal incontinence, women who received an episiotomy had fewer anal incontinence symptoms after 6 months. The effect of episiotomy was statistically significant, with a significance level of alpha = 5% (p = 0.0367).

Conclusion

TPUS is an accessible, non-invasive method for detecting, quantifying, following-up and monitoring OASIS in patients with third-degree perineal tears. The width, as obtained by sonography, is important with regard to the healing of OASIS. A mediolateral episiotomy seems to prevent anal incontinence after 6 months.

Effect of Prenatal Perineal Massage on Postpartum Perineal Injury and Postpartum Complications: A Meta-Analysis

Background

The efficacy of perineal massage is controversial. The study was aimed at comparing the effects of perineal massage on perineal injury and complications.

Methods

PubMed, Embase, the Cochrane Library, and ISI Web of Science were searched for literature on the relationship between prenatal perineal massage and postpartum perineal injury and complications until April 2022. Indicators included postpartum perineal tears, perineotomy, postpartum perineal pain, natural labour, and postpartum incontinence. Finally, RevMan5.4 software was used to analyze the extracted data.

Results

A total of 6487 subjects in 16 studies were included, with 3211 who received perineal massage and 3276 did not. There was no significant difference in 1-2 degree perineal tearing between the intervention group and the control group (RR = 0.96, 95% CI [0.90, 1.03], P = 0.30), and there was no heterogeneity between studies (P = 0.62, I² = 0%), indicating publication bias. Compared with the control group, prenatal perineal massage significantly reduced the incidence of 3-4 degree perineal tears (RR = 0.56, 95% CI [0.47, 0.67], P < 0.00001), and there was no heterogeneity between studies (P = 0.16, I² = 30%), indicating publication bias. Compared with the control group, prenatal perineal massage reduced the risk of lateral perineal resection (RR = 0.87, 95% CI [0.80, 0.95], P = 0.001), and there was no heterogeneity between studies (P = 0.14, I² = 31%), and there was no publication bias. Compared with the control group, prenatal perineal massage reduced the risk of postpartum pain at 3 months (RR = 0.64, 95% CI [0.51, 0.81], P = 0.0002). There was no significant heterogeneity among studies (P = 0.23, I² = 31%).

Conclusion

Compared with no prenatal perineal massage, prenatal perineal massage can reduce the risk of perineal injury, the incidence of lateral perineal resection, and the incidence of long-term pain.

Aspects of Pelvic Floor Protection in Spontaneous Delivery - a Review

The necessity of increasingly addressing aspects of pelvic floor protection, i.e., prevention of the most frequent female pelvic floor disorders, such as urinary incontinence, faecal incontinence and pelvic organ prolapse, is the result of the steadily improving understanding of the association of pregnancy and delivery with the prevalence of these disorders. About a quarter of all women experience one or more such symptoms during their life. Apart from age and weight, pregnancies and births play an important part. While initial discussion of pelvic floor protection often focused very rapidly on the mode of delivery and elective caesarean section as a possible protective intervention, it has become apparent in the last few decades how varied and wide-ranging the options are that can be used to protect against pelvic floor disorders. The mode of delivery as such is "only" one element among numerous other considerations and has diminished markedly in importance. Interprofessionality and interdisciplinarity undoubtedly represent an important development as resulting recommendations must always be incorporated in an overall context that considers mother and child at the same time. Considering the pelvic floor only certainly does not make sense. This review article will analyze in greater detail important pre-, intra- and postpartum aspects that in their entirety can provide insight into the various aspects of pelvic floor protection. The authors regard the following article as an additional basis for discussion on achieving a sustained reduction in the incidence and prevalence of female pelvic floor disorders.

Association between second stage of labour length and risk of obstetrical anal sphincter injury in nulliparous women: a population-based retrospective cohort study

INTRODUCTION AND HYPOTHESIS

Obstetrical anal sphincter injury (OASIS) is a common consequence of vaginal delivery in nulliparas and carries the risk of short- and long-term morbidity. The objective of this study was to estimate the association between the duration of the second stage of labour and OASIS risk.

METHODS

A population-based, retrospective cohort of nulliparas delivering singleton, vertex, non-anomalous fetuses at term in Nova Scotia, Canada, from 2005 to 2019, were identified using the Nova Scotia Atlee Perinatal Database. Poisson regression models were used to estimate risk ratios (RR) with robust 95% confidence intervals (CI) adjusting for confounding variables to investigate the association between the length of the second stage and OASIS in the entire cohort and in operative vaginal deliveries.

RESULTS

Of 36,662 participants, 7.6% sustained an OASIS (6.8% third-degree, 0.8% fourth-degree tear). The proportion of participants who sustained an OASIS increased over the study period. For each 30-min increase in the length of second stage, the OASIS risk increased by 11% (RR 1.11, 95% CI 1.10-1.12). When stratified by mode of delivery, second stage length ≥ 90 min was associated with an increased OASIS risk in spontaneous (RR 1.35, 95% CI 1.15-1.58) and vacuum-assisted vaginal deliveries (RR 1.42, 95% CI 1.11-1.81). In forceps-assisted vaginal deliveries, OASIS risk was increased, with shorter and longer durations of the second stage.

CONCLUSION

Increasing length of the second stage of labour was associated with increasing risk of OASIS overall, but the association was heterogeneous between modes of delivery. Length of the second stage should be considered in counseling about OASIS risk.

A core outcome set for clinical trials of first- and second-degree perineal tears prevention and treatment: a study protocol for a systematic review and a Delphi survey

BACKGROUND

Perineal tear is a common consequence of vaginal births affecting females globally. Even mild perineal tears could cause short- and long-term complications for females. Though many studies of interventions to prevent or treat perineal tears to minimize the consequences have been conducted, there is a significant heterogeneity in the outcomes measured and reported in existing studies, which makes meaningful comparison difficult and makes the generalizability to clinical practice challenging. Developing a core outcome set (COS) could solve these methodological concerns. In this paper, we report a protocol to develop a COS for clinical trials of mild perineal tears, which shall assist in establishing the evidence base and implementation of effective measures to reduce the incidence and minimize the consequences of mild perineal tears.

METHODS/DESIGN

The development of this COS will be guided by a study advisory group composed of obstetricians, midwives, nursing managers, service users, and methodologists. This study will include four stages: (1) a systematic research of the literature to identify outcomes reported in prior studies, (2) a semi-structured interview with key stakeholders to collect their opinions on important outcomes, (3) a panel of experts will be invited to conduct a three-round Delphi survey to prioritize these outcomes, and (4) a consensus meeting with key stakeholders to determine the list of outcomes included in the final COS.

DISCUSSION

The development of this COS will provide international standards for the outcomes to be collected and reported in all clinical trials and audits of practice, which involve prevention and treatment of first- and second-degree perineal tears for women with vaginal delivery. This will facilitate comparing and contrasting of studies and allow for combining of appropriate studies with the ultimate goal of improved perineal care for women choosing vaginal delivery.

Which elements were significant in reducing obstetric anal sphincter injury? A prospective follow-up study

Background

To examine which elements of an obstetric anal sphincter injury (OASI) care bundle were protective for OASI. Several interventional trials showed that application of a care bundle involving a hands-on approach to perineal protection may reduce the risk of OASI. Previously, we found that only the element “hand on the fetal head” in itself was protective, although the risk of a type 2 error was calculated to be 50%.

Methods

A prospective follow-up study in an obstetric department in Denmark with 3200 deliveries per year. We included a cohort of 10,383 women giving birth vaginally from gestational week 22 + 0 from 2016 through 2019. We documented on a person-level the five elements of the care bundle together with maternal and obstetrical characteristics. The elements were 1) communication, 2) visible perineum, 3) hand on fetal head, 4) perineal support and 5) certification. Regression analysis was used for analysis of associations. The primary outcome measure was OASI.

Results

The total rate of OASI in vaginally delivering women was 1.9%. The incidence was 3.2% in nulliparous women giving birth vaginally. The rate of cesarean section was 16.5% and for episiotomy 2.4%. The reduction in the incidence of OASI was sustained since 2013. Hand on the fetal head and perineal support both were protective factors for OASI. In case of a nulliparous woman with a neonate weighing 3500 g giving birth spontaneously, the relative risk (RR) for OASI was 0.50 (95% CI 0.49- 0.51) with use of hand on the fetal head together with perineal support against no use. Similarly, with a nulliparous woman giving birth to a neonate of 3500 g by vacuum extraction, the RR for OASI was 0.65 (95% CI 0.62-0.68) against no use.

Conclusions

Both hand on the fetal head and perineal support were associated with a reduced risk of OASI.
