Active versus expectant management for women in the third stage of labour

Efficacy of skin-to-skin contact between mother and newborn during the third stage of labour in reducing postpartum haemorrhage risk

OBJECTIVE

To evaluate the efficacy of skin-to-skin contact (SSC) in reducing the risk of postpartum haemorrhage and blood loss after childbirth.

BACKGROUND

Postpartum haemorrhage is a leading cause of preventable mortality, particularly in developing countries. Although various strategies exist for its prevention, the effect of SSC remains unclear.

DESIGN

Systematic review with meta-analysis.

DATA SOURCES

Searches were conducted in PubMed, Scopus, Cochrane Library, CINAHL, Google Scholar, and Web of Science up to May 2024.

REVIEW METHODS

The PRISMA guidelines were followed. Prospective clinical trials were included and assessed using the revised Cochrane RoB 2 tool for randomized controlled trials and ROBINS-I for non-randomized studies. The meta-analysis was performed using STATA 18.

RESULTS

The analysis of 18 prospective clinical trials showed that SSC during the third stage of labour was associated with a reduction in the incidence of uterine atony and a lower likelihood of blood loss greater than or equal to 500 mL. Additionally, SSC was linked to a decrease in mean blood loss during the third stage of labour, the first two hours postpartum, and at 24 h postpartum. No significant differences were found in the incidence of severe postpartum haemorrhage.

CONCLUSIONS

SSC during the third stage of labour appears to be effective in reducing the risk of uterine atony, blood loss of 500 mL or more, and mean postpartum blood loss. This suggests significant potential for improving obstetric outcomes. However, given the high risk of bias in the studies analysed, caution is required in interpreting these results. Further high-quality research is needed to confirm these benefits, particularly in caesarean sections.

IMPACT

Postpartum haemorrhage is one of the leading causes of maternal mortality, particularly in developing countries. This meta-analysis suggests that SSC during the third stage of labour could be a key intervention in reducing the risk of uterine atony, blood loss of 500 mL or more, and mean postpartum blood loss. These findings are especially relevant in countries where access to uterotonic drugs is limited, highlighting the need for cost-effective, evidence-based alternatives to improve maternal health.

The Yield of Amnioinfusion in the Prevention of Postpartum Hemorrhage

Although amnioinfusion decreases the rate of uterine atony, its effect on postpartum hemorrhage (PPH) is uncertain. This study aimed to assess whether amnioinfusion reduces the risk of PPH in laboring individuals.A retrospective study of all laboring singletons at a tertiary center between January 2013 and December 2022 at ≥34 weeks. Individuals with known major fetal anomalies, stillbirths, or missing delivery records were excluded. The primary outcome was PPH. Neonatal and secondary maternal outcomes were also explored. Adjusted odds ratios (aOR) were estimated using multivariable regression models.Out of 113,816 deliveries during the study period, 83,152 (77.1%) met inclusion criteria, and among them 4,597 (4.03%) had amnioinfusion. Laboring individuals with amnioinfusion were more commonly nulliparous, had more polyhydramnios, oligohydramnios, preeclampsia, gestational diabetes, and fetal growth restriction. Furthermore, individuals with amnioinfusion had a higher rate of labor induction (54.54 vs. 27.8%; p < 0.01) and a higher cesarean rate (36.9 vs. 9.5%; p < 0.01). Following multivariable regression, there was no significant difference in the rate of PPH among individuals who had an amnioinfusion (2.6%) versus those who did not (3.1%; aOR: 0.95, 95% confidence interval [CI]: 0.87, 1.27). The rates of endometritis (aOR: 1.4; 95% CI: 1.04-1.89) and postpartum fever (aOR: 1.70; 95% CI: 1.36-2.12) were higher in those who had amnioinfusion compared with those that did not.Among laboring individuals ≥ 34 weeks, intrapartum amnioinfusion was not associated with a reduction in the rate of PPH and was associated with a higher likelihood of infectious morbidity. · PPH stands as the foremost contributor to maternal mortality.. · There is limited information regarding the yield of amnioinfusion in the reduction of PPH.. · We evaluate whether amnioinfusion reduces the rate of PPH in laboring individuals ≥ 34 weeks..

Birth plans: Developing a shared medical decision aid tool

OBJECTIVE(S)

Birth plans appeared at the end of the twentieth century, enabling women to express their expectations towards childbirth. This reflects a rising demand for patients to take a proactive role in their medical care. This study aimed to collaboratively develop a medical decision aid with expectant mothers to prepare them better for the events surrounding their child's birth.

STUDY DESIGN

Five topics frequently addressed in birth plans were identified by both patients' associations, using semi-structured interview with representatives of women's associations, and professionals, using an online poll. Initially, work groups with perinatal care professionals drafted items designed to guide expectant mothers in developing their birth plans and actively participating in childbirth decisions. Subsequently, we used a modified Delphi-consensus in three rounds to retain the most relevant items. The first two rounds engaged a multidisciplinary team of professionals, while the third involved expectant mothers from two maternity wards in Lyon, France. Items that received a rating between 3 (good value) and 4 (excellent value) on a 4-point scale by more than 75% of participants were deemed consensual. The study assessed inter-rater agreement using the Fleiss kappa score.

RESULTS

The professional work groups proposed a total of 124 items distributed across five themes: analgesia during labour, drug administration before and during labour, events in the delivery room, initial neonatal care, and perineal protection. Ultimately, 65.3% of the initial 124 items were deemed relevant by both the experts and the expectant mothers. Notably, the most significant differences in consensus centered around analgesia and the complexity of information. Non-medicinal analgesic methods were favored by mothers-to-be but not by professionals. Conversely, detailed information on delayed cord clamping were favored by experts.

CONCLUSIONS

A modified Delphi consensus was used to create with expectant mothers a decision aid tool to help them write their birth projects, addressing five main topics that are frequently reported in the literature. We now need to test this tool in clinical practice to assess its relevance in routine obstetrics consultation.

A rapid and effective approach to building a life-saving multidisciplinary team for transferred postpartum haemorrhage patients: leveraging trauma experience-a retrospective study

BACKGROUND

Establishing an efficient multidisciplinary team for transferred postpartum haemorrhage (PPH) cases is challenging due to limited clinical exposure. We hypothesised that leveraging trauma team experience could effectively facilitate the development of such a team within a short timeframe.

METHODS

In September 2019, a multidisciplinary team was established at our tertiary care centre to provide rapid management of critical PPH cases transferred from the obstetric clinic, prioritising immediate resuscitation and haemostatic interventions. This historical cohort study (2017-2022) compared outcomes before (2017-2018, before group [BG]) and after (2019-2022, after group [AG]) team establishment. Outcomes included process-related quality indicators, clinical measures such as length of hospital stay, intensive care unit (ICU) days, presence of the lethal triad, and hysterectomy rate.

RESULTS

Of the 71 PPH patients transferred during the study period, 24 were in the BG and 47 in the AG. The AG demonstrated higher use of tranexamic acid (33.33% vs. 74.47%, P = 0.002), shorter time to the first blood transfusion (11 vs. 8 min, P = 0.029), and increased rates of arrival in the operating room within 60 min (25% vs. 80%, P = 0.014). Clinical outcomes showed reduced rates of cardiopulmonary resuscitation (16.67% vs. 0%, P = 0.011) and shorter ICU stays (4 vs. 1 day, P = 0.005) in the AG.

CONCLUSIONS

Leveraging trauma team expertise is an effective strategy for establishing a multidisciplinary PPH team, significantly improving outcomes for critically ill PPH patients transferred from obstetric clinics.

Duration of the second and third stages of labor and risk of postpartum hemorrhage: a cohort study stratified by parity

BACKGROUND

Postpartum hemorrhage (PPH) remains a leading cause of maternal morbidity and mortality worldwide. It is therefore important to improve our understanding of the risk factors for PPH according to parity, in particular, those linked to modifiable obstetric practices. The aim of this study was to assess the risk of PPH by the duration of the second and third stages of labor, stratified by parity.

METHODS

This study was based on secondary analysis of data from participants in a randomized controlled trial. A sample of women from three university hospitals in France aged at least 18 years, with a singleton pregnancy, in the first stage of labor, at 36-42 weeks of gestation, with epidural anesthesia and a vaginal delivery were included. The main outcome was PPH rates, defined by blood loss > 500 mL within 2 h after delivery. Characteristics of mothers, newborns, labor, and delivery, and their relation to PPH were explored with multivariable regression models.

RESULTS

Of 1598 women included, 864 were nulliparous and 680 parous; their respective PPH rates were 9.1% (79/864) and 7.4% (54/680) (P = 0.2), and the overall rate 8.3% (133/1598). The multivariable analysis found that PPH was associated with the durations of both oxytocin exposure (aOR 1.10, 95%CI 1.01-1.20) and the third stage of labour (aOR 1.80, 95%CI 1.37-2.38) among nulliparous women, and the PPH risk increased with both duration of the third stage (aOR 2.10, 95%CI 1.56-2.83) and history of PPH (aOR 3.02, 95%CI 1.38-6.59) among parous women.

CONCLUSIONS

The duration of oxytocin exposure was found to be a risk factor for PPH among nulliparous women as was a history of PPH among parous women. Future studies should focus on duration of third stage of labor, especially when active management of the third stage of labor (AMTSL) is routinely used.

TRIAL REGISTRATION

The trial was registered at ClinicalTrials.gov NCT01113229.

Interventional radiology for prevention and management of postpartum haemorrhage: a single centre retrospective cohort study

PURPOSE

Postpartum haemorrhage (PPH) remains a leading cause of maternal death despite current medical management. Surgical interventions are still needed for refractory bleeding. Interventional radiology (IR) can be a successful intermediary that avoids the need for hysterectomy. Nevertheless, IR outcome data in a peripartum setting are limited. The objective of this study is to document the efficacy and safety of IR.

METHODS

Retrospective study reviewed the records of consecutive patients who underwent peripartum IR from 01/01/2010 until 31/12/2020 in a tertiary academic centre. Patients were divided in a prophylactic and a therapeutic group. Information about interventions before and after IR, and IR specific complications was retrieved. Efficacy was defined by the number of transfusions and additional surgical interventions needed after IR, and safety was assessed by the incidence of IR related complications.

RESULTS

Fifty-four patients, prophylactic group (n = 24) and therapeutic group (n = 30), were identified. In both groups, IR was successful with 1.5 ± 2.9 packed cells transfused post-IR (1.0 ± 2.1 prophylactic vs 1.9 ± 3.3 therapeutic; p = 0.261). Additional surgical interventions were required in n = 5 patients (9.2%), n = 1 (4.2%) in the prophylactic vs. n = 4 (13.3%) in the therapeutic group. Complications were reported in n = 12 patients (22.2%), n = 2 (8.3%) prophylactic vs. n = 10 (33.3%) in therapeutic group. Mostly minor complications, as puncture site hematoma or bleeding, were reported in n = 4 (7.4%). Severe complications as necrosis and metabolic complications were reported in n = 2 patients (3.9%).

CONCLUSION

IR for prevention and treatment of PPH was highly successful and associated with minor complications.

Assisted reproductive technology and prolonged third stage of labour: a multicentre study in Japan

RESEARCH QUESTION

What are the risk factors for a prolonged third stage of labour, closely related to postpartum haemorrhage, and what is the effect of assisted reproductive technology (ART) on the third stage of labour?

DESIGN

Clinical data of women who delivered vaginally at term at 12 primary maternity hospitals in Japan (2010-2018) (n = 25,336) were obtained; 1148 (4.5%) conceived through ART and 2246 (8.9%) through non-ART treatments. The risk of a prolonged third stage of labour (defined as ≥20 min) was evaluated by univariable and multivariable regression analyses. Adjusted odds ratios (aOR) of a prolonged third stage of labour were evaluated, stratified by the type of ART, with natural conception as a reference.

RESULTS

Multivariable analysis showed that pregnancy achieved through ART (aOR 4.38, 95% CI 3.12 to 6.15), history of spontaneous miscarriage (OR 1.40, 95% CI 1.06 to 1.84) and prolonged labour (OR 1.52, 95% CI 1.09 to 2.12) were identified as independent risk factors. Frozen embryo transfer (FET), FET in a hormone replacement cycle (HRC-FET) and blastocyst-stage embryo transfer were significantly associated with a prolonged third stage of labour (aOR 4.07, 95% CI 2.75 to 6.04, aOR 4.11, 95% CI 2.58 to 6.57 and aOR 2.13, 95% CI 1.15 to 3.95, respectively). No significant difference was observed in the duration of third stage of labour between natural conception and non-ART treatment (P = 0.61).

CONCLUSION

Pregnancy achieved through ART, particularly FET, HRC-FET and blastocyst-stage embryo transfer, was a significant risk factor for a prolonged third stage of labour.

Postpartum Hemorrhage in Humanitarian Settings: Heat-Stable Carbetocin and Tranexamic Acid Implementation Study in Uganda

Background and Objective

Postpartum hemorrhage (PPH) remains a major concern in crisis-affected settings. There is a lack of strategies for implementing heat-stable carbetocin (HSC) and tranexamic acid (TXA) in humanitarian settings. This study aims to investigate the impact of a capacity-strengthening package on the utilization of uterotonics for PPH prevention, PPH detection, and utilization of TXA for PPH treatment in basic obstetric care clinics in humanitarian settings in Uganda.

Methods

A multi-stepped implementation research study was conducted, wherein six select facilities utilized an intervention package encompassing provider training, an online community of practice, and wall-displayed PPH algorithms. Facilities were conveniently assigned to the same study sequence: T1 (routine care), a transition period for training; T2 (package without HSC and TXA); T3 (package with HSC); and T4 (package with HSC and TXA). The primary outcomes assessed trends in prophylactic uterotonic use (including HSC), visual diagnosis of hemorrhage, and HSC and TXA use for hemorrhage treatment. Analysis followed an intention-to-treat approach, adjusting for cluster effect and baseline characteristics. Pan-African Clinical Trials Registry: PACTR202302476608339.

Results

From April 10, 2022, to April 4, 2023, 2299 women were recruited (T1: 643, T2: 570, T3: 580, T4: 506). Over 99% of all women received prophylactic uterotonics across the four phases, with oxytocin alone primarily used in T1 (93%) and T2 (92%) and HSC alone in T3 (74%) and T4 (54%) (T4-T1 95% CI: 47.8-61.0). Hemorrhage diagnosis ranged from 1% to 4%. For hemorrhage treatment, universal oxytocin use in T1 and T2 decreased in T3 and T4 after HSC introduction (T4-T1: 33%-100%; 95% CI: -100.0 to -30.9), and TXA use increased in T4 (T4-T1: 33%-0%; 95% CI: -2.4 to 69.1).

Conclusion and Global Health Implications

An intervention package to reinforce providers' capacity to prevent and treat PPH can result in substantial HSC utilization and a moderate TXA adoption in cold-chain-challenged humanitarian settings. It could be scaled up with continuous capacity development and supportive supervision to mitigate confusion between existing and new medications, such as the decreased use of oxytocin for PPH treatment. Maintaining investments in cold-chain strengthening remains critical to ensure the quality of oxytocin.

An Implementation Research Study on Uterotonics Use Patterns and Heat-stable Carbetocin Acceptability and Safety for Prevention of Postpartum Hemorrhage in Nigeria

Background and Objective

The burden of maternal mortality attributable to postpartum hemorrhage (PPH) remains high in Nigeria. Currently, oxytocin, and misoprostol, which are largely of suboptimal quality, are used for PPH prevention and treatment. Heat-stable carbetocin (HSC) is a viable uterotonic option for PPH prevention in a setting like Nigeria where compromised supply and cold chain systems result in the preponderance of poor-quality oxytocin and suboptimal PPH management. It is crucial to understand how healthcare providers (HCPs) accept and use HSC for PPH prevention, and what factors encourage correct uterotonic usage in health facilities, given PPH's ongoing public health challenge. This study aims to elucidate the current prophylactic use of HSC, oxytocin, and misoprostol in secondary and tertiary public health facilities while assessing HSC acceptability to clinicians and establishing factors that enable the appropriate use of uterotonics in health facilities.

Methods

Descriptive analysis conducted on quantitative data from patient chart reviews, HCP interviews and assessment, and facility assessment using Stata 15 and Microsoft Excel are presented as counts and percentages, while qualitative data from key informant interviews and in-depth interviews are coded and analyzed using NVivo. The findings from 18 publicly owned secondary and tertiary healthcare facilities across Kano, Lagos, and Niger states in Nigeria were interpreted according to thematic areas. Health facilities selection criteria were high volume of deliveries (≥30 deliveries per month), accessible location, availability of trained HCPs (specifically doctors, nurses, and midwives), and willingness to participate in the study.

Results

HSC was administered prophylactically in 10,284 (56%) of 18,364 deliveries, with a total of 148 (0.8%) women developing PPH. Approximately 76% of HCPs preferred HSC for PPH prevention compared to other available uterotonics, with clinical guidance from senior HCPs (76%), in-service training (76%), mentoring (84%), and supportive supervision (75%) contributing significantly to the choice and practice of uterotonics use by HCPs.

Conclusion and Global Health Implications

HSC, a thermostable analog of oxytocin, holds the potential to prevent PPH without the added cost of administering additional uterotonics and interventions. The introduction of HSC requires concerted procurement and capacity-building efforts to create an enabling environment for scale-up. HSC is non-inferior to oxytocin in preventing PPH, has few side effects compared to misoprostol or oxytocin-misoprostol combination, and more cost-effective when compared with the other three uterotonics. Although the geographical scope of our study is only three states in Nigeria, the preponderance of suboptimal uterotonics across the country makes our findings applicable to the whole country and other low- and middle-income countries with similar challenges.

Postpartum Hemorrhage in Humanitarian Settings: Implementation Insights from Using Heat-Stable Carbetocin and Tranexamic Acid

Background and Objective

Maternal mortality, largely due to postpartum hemorrhage (PPH), remains high in resource-limited and crisis-affected settings, where heat-stable carbetocin (HSC) and tranexamic acid (TXA) offer promise for PPH prevention and treatment but lack evidence. This study, implemented in basic maternity facilities within humanitarian settings, explores healthcare providers' perspectives on an HSC and TXA-inclusive PPH intervention package and related operational challenges and facilitators.

Methods

Based on semi-structured interview guides and using thematic analysis, this qualitative research, through 13 focus group discussions and individual interviews, investigated the perspectives of 64 healthcare staff (mostly midwives) from eight basic emergency obstetric care facilities in South Sudanese and Ugandan settings hosting large numbers of forcibly displaced populations. The PPH intervention package comprised refresher training, an online provider community, PPH readiness kits, alarm bells, and displayed algorithms.

Results

Findings from both countries converged, highlighting providers' positive views on HSC and TXA. HSC effectiveness in preventing bleeding was acknowledged, bolstering staff's confidence in its use. TXA was perceived as effective although providers reported having less experience with it due to the limited number of PPH cases. Enabling factors included the ease of administration, practical training, endorsement by national and local authorities, and the absence of a cold chain requirement. Appreciation was given to the WhatsApp community of practice as it facilitated knowledge exchange, quality improvement projects that enhanced PPH diagnosis, and innovative tools like wall clocks to record the timing of clinical actions and bells to call for assistance. Challenges included confusion between new and existing medications and record systems that inadequately capture HSC, TXA, and other PPH indicators.

Conclusion and Global Health Implications

HSC and TXA integrated into a PPH intervention package were overall positively valued by providers in humanitarian settings. Continued education and support are crucial. Addressing challenges like medication confusion underscores the need for ongoing education and clear guidelines for the use of HSC, TXA, oxytocin, and other drugs for PPH prevention and treatment. Our findings stress the importance of a comprehensive strategy to overcome health system barriers in PPH management, potentially improving maternal health outcomes in resource-limited and fragile contexts, with broader global implications.

Knowledge and factors associated with active management of the third stage of labor in sub-Saharan Africa: A systematic review and meta-analysis

BACKGROUND

Postpartum hemorrhage (PPH) is one of the leading causes of maternal mortality in sub-Saharan Africa. Implementing active management in the third stage of labor has significantly reduced the incidence of PPH. Thus, understanding the level of healthcare providers' knowledge of active management in the third stage of labor can inform guidelines, policies, and practices for effectively preventing PPH.

OBJECTIVE

This review aimed to assess the level of healthcare providers' knowledge and associated factors of active management in the third stage of labor in sub-Saharan Africa.

SEARCH STRATEGY

We conducted a search using PubMed, Scopus, Web of Science, Google Scholar, Cochrane Library, and the African Journals online international databases.

SELECTION CRITERIA

The inclusion criteria were determined before the review of the articles and adhere to the criteria of population, intervention, comparison, and outcome.

DATA COLLECTION AND ANALYSIS

Statistical analysis was performed using STATA data analysis software version 14, while Microsoft Excel was utilized for data abstraction. We checked publication bias using a funnel plot and Egger and Begg regression tests. A P value less than 0.05 was considered statistically significant, suggesting the presence of presence publication bias. The I2 statistic was used to assess heterogeneity between studies. The study's overall effect was evaluated using the random effects model.

MAIN RESULT

The study included 20 studies to conduct a pooled prevalence analysis. The overall prevalence of healthcare providers' knowledge of active management of third-stage labor in sub-Saharan Africa was 47.975% (95% CI: 32.585, 63.365). Having pre- and in-service training (AOR: 2.25, 95% CI: 1.00, 5.08), having a higher degree (AOR: 1.98, 95% CI: 1.39, 2.82), and having good practices (AOR: 8.91, 95% CI: 4.58, 17.40) were significantly associated with healthcare provider's knowledge regarding active management third stage of labor.

CONCLUSIONS

The overall healthcare providers' knowledge of active management of the third stage of labor (AMTSL) was low in sub-Saharan Africa. Obstetric healthcare providers should undertake comprehensive training covering all AMTSL components through pre- and in-service diploma training programs.

Postpartum Hemorrhage in Humanitarian Settings: Heat-Stable Carbetocin and Tranexamic Acid Implementation Study in South Sudan

Background and Objective

Postpartum hemorrhage (PPH) remains a significant concern in crisis-affected contexts, where the implementation of heat-stable carbetocin (HSC) and tranexamic acid (TXA) for PPH prevention and treatment lacks evidence. This study aims to evaluate the effects of a capacity-strengthening package on the use of uterotonics for PPH prevention and detection, and the use of TXA for PPH treatment in basic maternity facilities in South Sudan.

Methods

In this implementation study, the six chosen facilities followed a stepwise sequence of PPH management: T1 (routine care), a transition period for package design; T2 (package without HSC and TXA); T3 (package and HSC); and T4 (package with HSC and TXA). The intervention comprised refresher training, an online provider community, PPH readiness kits, alarm bells, and displayed algorithms. The main outcomes were trends in prophylactic uterotonic use, including HSC, visual diagnosis of bleeding, and oxytocin and TXA use for PPH treatment. Analyses were adjusted for cluster effect and baseline characteristics. The study was registered in the Pan-African Clinical Trials Registry (PACTR202302476608339).

Results

From February 1, 2022, to February 17, 2023, 3142 women were recruited. Nearly all women received prophylactic uterotonics across all four phases, with a significant increase after T3 (T4-T1: 100%-98%; 95% CI: 4.4-0.4). Oxytocin alone was the most used in T1 (98%) and T2 (94%) and HSC alone in T3 (87%) and T4 (82%) (T4-T1: 95% CI: 75.5-83.3). PPH diagnosis tripled from 1.2% of all births to 3.6% (T2-T1: 95% CI: 0.4-5.2) and stayed roughly at 3% in T3 and T4. For treatment, universal oxytocin use in T1 and T2 decreased in T3 upon HSC initiation (T3-T2: 27%-100%; 95% CI: 95.5-49.9), whereas TXA use increased in T4 (T4-T1: 95%-0%; 95% CI: 54.6-99.0).

Conclusion and Global Health Implications

An intervention package to improve the quality of PPH prevention and treatment can effectively increase HSC and TXA use in crisis settings. It could be scaled up in similar contexts with ongoing supervision to mitigate confusion between the existing and new medications, such as the reduced use of oxytocin for PPH treatment. Sustaining cold chain investments remain vital to ensure oxytocin quality.

Roles and challenges encountered by midwives in the management of postpartum haemorrhage following normal vaginal delivery: A scoping review

AIMS

To establish a comprehensive understanding of the roles of midwives and the challenges they encounter in the prevention, diagnosis and management of postpartum haemorrhage (PPH) following normal vaginal delivery.

DESIGN

We conducted a scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Scoping Reviews (PRISMA-ScR) recommendations.

METHODS

We considered studies related to the roles of midwives and the challenges they encounter in the prevention, diagnosis and management of PPH during vaginal delivery. We excluded guidelines, consensuses, abstracts of meetings and non-English language studies. Databases, including the Cochrane Library, PubMed, Web of Science, Ovid, Medline, Embase, JBI EBP and BIOSIS Previews, were searched on January 1, 2023, with no time limitations.

RESULTS

We included 28 publications. Midwives play important roles in the prevention, diagnosis and management of postpartum haemorrhage during vaginal delivery. In the prevention of PPH, midwives' roles include identifying and managing high-risk factors, managing labour and implementing skin-to-skin contact. In the diagnosis of PPH, midwives' roles include early recognition and blood loss estimation. In the management of PPH, midwives are involved in mobilizing other professional team members, emergency management, investigating causes, enhancing uterine contractions, the repair of perineal tears, arranging transfers and preparation for surgical intervention. However, midwives face substantial challenges, including insufficient knowledge and skills, poor teamwork skills, insufficient resources and the need to deal with their negative emotions. Midwives must improve their knowledge, skills and teamwork abilities. Health care system managers and the government should give full support to midwives. Future research should focus on developing clinical practice guidelines for midwives for preventing, diagnosing and managing postpartum haemorrhage.

Third-Stage Complications Among In Vitro Fertilization Pregnancies: An Observational Study

OBJECTIVE

This study aimed to determine the third-stage complications and their risk factors in in vitro fertilization (IVF) pregnancies.

METHODS

This prospective observational study was conducted from March 2022 to November 2023 at a tertiary care university hospital in South India. We included a total of 217 women following IVF conception, and details of the third-stage labor complications were documented and expressed as the frequency with percentage. The risk factors were analyzed using a logistic regression model.

RESULTS

Among 217 participants, 51 (23.5%) had third-stage complications. Postpartum hemorrhage (PPH) was the most common, complicating 20% of the deliveries. Multiple gestations (adjusted odds ratio (aOR) 2.7, 95% confidence interval (CI) 1.03-7.46, p = 0.04), operative vaginal delivery (aOR 57, 95% CI 4.2-770, p = 0.002), and emergency cesarean section (aOR 14.8, 95% CI 1.3-160.5, p = 0.026) were the risk factors for PPH. Intrapartum infection was found to be associated with a risk for the retained placenta (aOR 8, 95% CI 1.37-46.4, p = 0.02) and adherent placenta (aOR 6.06, 95% CI 1.07-34.3, p = 0.04). Assisted reproductive technology (ART)-related factors were not found to be significantly associated with third-stage complications.

CONCLUSION

There is a risk of third-stage complications, especially postpartum hemorrhage, among IVF pregnancies. The type of embryo transfer was not associated with third-stage complications.

Obesity at term: What to consider? How to deliver?

Obesity presents significant challenges during pregnancy, increasing the risk of complications and adverse outcomes for both mother and baby. With the rising prevalence of obesity among pregnant women, questions arise regarding optimal management, including timing of delivery and choice of delivery mode. Labour induction in obese women may require a combination of mechanical and pharmacological methods due to increased risk of failed induction. Caesarean section in obese women presents unique challenges, requiring comprehensive perioperative planning and specialized care to optimize outcomes. However, specific guidelines tailored to obese patients undergoing caesarean sections are lacking. Postpartum care should include vigilant monitoring for complications. Addressing obesity in pregnancy necessitates a multidisciplinary approach and specialized care to ensure the best outcomes.

Effects of timing of umbilical cord clamping for mother and newborn: a narrative review

OBJECTIVE

This narrative review was performed to evaluate the correct timing of umbilical cord clamping for term infants. It was intended to determine any advantages or disadvantages from early or delayed cord clamping for newborns, infants or mothers.

METHODS

A systematic search on two databases was conducted using the PICO pattern to define a wide search. Out of 43 trials, 12 were included in this review. Three of the included studies are meta-analyses, nine are randomized controlled trials.

RESULTS

Early or delayed cord clamping was defined differently in all the included trials. However, there are many advantages from delayed cord clamping of at least > 60 s for newborns and infants up to 12 months of age. The trials showed no disadvantages for newborns or mothers from delayed cord clamping, except for a lightly increased risk of jaundice or the need for phototherapy.

CONCLUSION

Delayed umbilical cord clamping for term infants should be performed. Further research is needed to improve knowledge on physiological timing of umbilical cord clamping in term infants, which also leads to the same advantages as delayed cord clamping.

How midwives facilitate informed decisions in the third stage of labour - an exploration through portraiture

PROBLEM

Midwifery philosophy promotes informed decision-making. Despite this, midwives report a lack of informed decision-making in standard maternity care systems.

BACKGROUND

Previous research has shown a woman's ability to make informed decisions within her maternity care significantly impacts her childbearing experience. When informed decision-making is facilitated, women report positive experiences, whereas when lacking, there is an increased potential for birth trauma.

AIM

To explore midwives' experiences of facilitating informed decision-making, using third-stage management as context.

METHODS

Five midwives from Victoria, Australia, were interviewed about their experiences with informed decision-making. These interviews were guided by portraiture methodology whereby individual narrative portraits were created. This paper explores the shared themes among these five portraits.

FINDINGS

Five individual narrative portraits tell the stories of each midwife, providing rich insight into their philosophies, practices, barriers and enablers of informed decision-making. These are then examined as a whole dataset to explore shared themes, and include; 'informed decision-making is fundamental to midwifery practice' 'the system', and 'navigating the system'. The system contained the sub-themes; hierarchy in hospitals, the medicalisation of birth, and the impact on midwifery practice, and 'navigating the system' - contained; safety of the woman and safety of the midwife, and the gold-standard of midwifery.

DISCUSSION AND CONCLUSION

Midwives in this study valued informed decision-making as fundamental to their philosophy but also faced barriers in their ability to facilitate it. Barriers to informed decision-making included: power-imbalances; de-skilling in physiological birth; fear of blame, and interdisciplinary disparities. Conversely enablers included continuity models of midwifery care, quality antenatal education, respectful interdisciplinary collaboration and an aim toward a resurgence of fundamental midwifery skills.

[Postpartum Hemorrhage]

Postpartum hemorrhage (PPH) affects about 4% of all deliveries in high-income countries and continues to rise, a trend attributable to the increase in caesarean section rates and maternal morbidity. Preventive measures such as the precautionary administration of uterotonics effectively reduce the risk of severe bleeding irrespective of birth mode. As a time-critical condition and a significant contributor to adverse maternal outcomes, PPH needs to be diagnosed early by measuring, not estimating, blood losses. Institutional treatment algorithms should be available to guide stage-based interdisciplinary management without delay. The main therapy goals are to identify the etiology and stop the bleeding by using uterotonics and mechanical and surgical interventions, to restore hemodynamic stability by volume and transfusion therapy and to optimize hemostasis by laboratory- and viscoelastic assay-guided factor replacement. This review highlights current recommendations for prevention, diagnosis and treatment of PPH.

Active management of the third stage of labor and associated factors among maternity care providers in public health facilities in Eastern Ethiopia: a multi-center study

INTRODUCTION

The third stage of labor is the shortest, most critical, and hazardous stage as it is linked with postpartum hemorrhage, the leading cause of maternal mortality and morbidity. Postpartum hemorrhage can be prevented by 60% with active management of the third stage of labor (AMTSL). Few studies have been conducted in different parts of Ethiopia showing rates of AMTSL ranging from 16.7% to 43.3%. Limited information, however, exists about its practice in our study area. Thus, we aimed to assess the practice of AMTSL and associated factors among maternity care providers in public health facilities in eastern Ethiopia.

METHODS

An institution-based cross-sectional study design was used among 270 maternity care providers in public health facilities in eastern Ethiopia. They were recruited using cluster sampling techniques in their health facilities from July 15-October 30/2021. Pretested self-administered questionnaires and an observational checklist were used to collect data. Descriptive, binary, and multivariable logistic regression analyses were performed. Adjusted odds ratios with 95% confidence intervals were used for statistically significant associations.

RESULTS

Good practice of AMTSL occurred in 40.3% (95% CI: 34.5%-46.1%) of births. Being trained (aOR 3.02; 95% CI 1.60-5.70); presence of birth assistance (aOR 2.9; 95% CI 1.42-6.04); having the highest educational level (aOR 4.21; 95% CI 1.08-16.40); and having good knowledge (aOR 3.00; 95% CI 1.45-6.20) were factors statistically associated with maternity care providers' good practice of AMTSL.

CONCLUSION

Active management of the third stage of labor was practiced with low rates in the study area. Therefore, we suggest that the stakeholders could enhance the presence of birth assistance during all births and provide education to attain higher educational levels and continuously update the maternity care providers' level of knowledge through comprehensive and on-the-job training to increase the good practice of the third stage of labor.

The effect of date fruit consumption on early postpartum hemorrhage: a randomized clinical trial

BACKGROUND

Postpartum hemorrhage, anemia, and iron deficiency are important health problems. Using safe, cheap, and available methods to reduce the amount of hemorrhage after childbirth can be effective for the mother's health during this period. Therefore, this study was conducted to determine the effect of date fruit consumption on the amount of hemorrhage after natural childbirth.

METHODS

This randomized clinical trial was conducted on 98 women referred to the maternity ward of Al-Zahra Hospital in Rasht using the available sampling method. The primary outcome was postpartum hemorrhage, measured using the Pictorial Blood Loss Assessment Chart (PBLAC). Two hours after delivery, 100 g of date fruits were given to the intervention group, and the amount of hemorrhage was recorded during the first 24 h. Comparison between the two groups was done with the Mann-Whitney test with the Hodges-Lehmann estimator and corresponding exact conditional nonparametric confidence interval (CI) as effect estimate. A P < 0.05 was considered significant.

RESULTS

The median of postpartum hemorrhage after normal delivery in the date and control groups was 35.0 [interquartile range (IQR): 22.0 to 39.8] and 39.0 [IQR: 27.5 to 64.5], respectively. Using the Hodges-Lehmann estimator, on average, the median postpartum hemorrhage in the date group was 9.0 (95% CI: 2.00-18.0) units lower than the control group (P = 0.009).

CONCLUSION

Consumption of dates effectively reduces the amount of hemorrhage after natural childbirth; thus, consuming this fruit during postpartum period is recommended. Also to confirm the findings, it is recommended to conduct similar studies in this field.

Practices and factors associated with active management of the third stage of labor in East Africa: systematic review and meta-analysis

BACKGROUND

Active management of the third stage of labor involves prophylactic uterotonics, early cord clamping, and controlled cord traction to deliver the placenta. It is designed to facilitate the delivery of the placenta by increasing uterine contractions during the third stage of labor. It is also used to prevent postpartum hemorrhage by averting uterine atony.This systematic review and meta-analysis's emphasis was on the practice and factors associated with active management of the third stage of labor in East Africa.

METHODS

PubMed, Web of Science, Science Direct (Scopus), Google Scholar, African Journals Online, and the Cochrane Library electronic databases were used. Data were extracted using Microsoft Excel, and STATA version 14 was used for analysis. A p-value of 0.05 is regarded to indicate potential publication bias: the funnel plot, Begg, and Egger's regression test were used to examine publication bias. Using I² statistics, the heterogeneity of the studies was evaluated. Pooled analysis was carried out. By country, a subgroup analysis was conducted.

RESULTS

Thirteen studies were included in this systematic review and meta-analysis. The pooled prevalence of the practice of active management of the third stage of labor in East Africa was 34.42%. Received training (OR = 6.25, 95%CI = 3.69, 10.58), years of experience (OR = 3.66, 95%CI = 2.35, 5.71), and good knowledge (OR = 3.66, 95%CI = 2.35, 5.71) were statically associated with the practice of active management of third stage of labor.

CONCLUSION

The pooled prevalence of practice for active management of the third stage of labor in East Africa was low. Factors that were statistically associated with the practice were received training, years of experience, and good knowledge. Obstetric care providers should continue to receive training in all components of active management of the third stage of labor through training and education programs.

Skin-to-Skin Contact in the Third Stage of Labor and Postpartum Hemorrhage Prevention: A Scoping Review

INTRODUCTION

Literature supports numerous benefits of skin-to-skin contact for neonatal adaptation to extrauterine life and bonding/attachment, but few studies explore the effects of skin-to-skin contact on maternal outcomes. This review aims to map the evidence on skin-to-skin contact in the third stage of labor for postpartum hemorrhage prevention.

METHODS

Scoping review, which covered stages recommended by the Institute Joanna Briggs, including studies from the PubMed, EMBASE, CINAHL, LILACS, Web of Science, and Scopus databases, using the descriptors "Postpartum hemorrhage", "Labor stages, third", "Prevention" and "Kangaroo care/Skin-to-skin".

RESULTS

100 publications on the subject found, 13 articles met the inclusion criteria, with 10,169 dyads were assessed in all studies. Publications from 2008 to 2021 were mostly written in English and designed as a randomized controlled trial. Skin-to-skin contact was effective and significant in: reducing the duration of the third stage of labor; placenta delivery; uterine contractility and physiological involution; absence of atony, decreasing blood loss with lower rates of erythrocyte and hemoglobin drop; reducing the need for synthetic oxytocin and/or ergometrine to control bleeding; and reducing changing pads per period and length of stay.

DISCUSSION

Skin-to-skin contact was considered an effective, low-cost, and safe strategy, with positive effects already established in the literature for infants and extremely favorable results in postpartum hemorrhage prevention cases, being highly recommended in assistance for the dyad.

Effect of delayed versus immediate umbilical cord clamping in vaginal delivery at term: A randomized clinical trial

OBJECTIVE

To compare maternal blood loss with immediate cord clamping versus delayed cord clamping in women undergoing spontaneous vaginal delivery at term.

METHODS

Parallel group non-blinded randomized trial conducted at a single center in Italy. Women with singleton gestations who underwent spontaneous vaginal delivery at term were eligible and were randomized in a 1:1 ratio to either immediate or delayed cord clamping. In the immediate cord clamping group, cord clamping was within 15 s after birth. In the delayed cord clamping group, cord clamping was after more than 60 s, or when the cord had stopped pulsing. The primary outcome was change in maternal hemoglobin level from the day of delivery to day one after delivery.

RESULTS

A total of 122 participants were enrolled in the trial. There were no significant differences in maternal blood loss as assessed by comparing the decrease in maternal hemoglobin level (mean difference - 0.10 g/dl, 95% confidence interval - 0.28 to 0.08) between the two groups. The mean hemoglobin level at postdelivery day 1 was 11.0 ± 1.5 g/dl in the delayed group and 11.3 ± 1.6 g/dl in the immediate group.

CONCLUSIONS

Delayed umbilical cord clamping, compared with immediate umbilical cord clamping, resulted in no significant change in maternal hemoglobin level 1 day after delivery.

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.

Physiological-based cord clamping in very preterm infants: the Aeration, Breathing, Clamping 3 (ABC3) trial-study protocol for a multicentre randomised controlled trial

BACKGROUND

International guidelines recommend delayed umbilical cord clamping (DCC) up to 1 min in preterm infants, unless the condition of the infant requires immediate resuscitation. However, clamping the cord prior to lung aeration may severely limit circulatory adaptation resulting in a reduction in cardiac output and hypoxia. Delaying cord clamping until lung aeration and ventilation have been established (physiological-based cord clamping, PBCC) allows for an adequately established pulmonary circulation and results in a more stable circulatory transition. The decline in cardiac output following time-based delayed cord clamping (TBCC) may thus be avoided. We hypothesise that PBCC, compared to TBCC, results in a more stable transition in very preterm infants, leading to improved clinical outcomes. The primary objective is to compare the effect of PBCC on intact survival with TBCC.

METHODS

The Aeriation, Breathing, Clamping 3 (ABC3) trial is a multicentre randomised controlled clinical trial. In the interventional PBCC group, the umbilical cord is clamped after the infant is stabilised, defined as reaching heart rate > 100 bpm and SpO₂ > 85% while using supplemental oxygen < 40%. In the control TBCC group, cord clamping is time based at 30-60 s. The primary outcome is survival without major cerebral and/or intestinal injury. Preterm infants born before 30 weeks of gestation are included after prenatal parental informed consent. The required sample size is 660 infants.

DISCUSSION

The findings of this trial will provide evidence for future clinical guidelines on optimal cord clamping management in very preterm infants at birth.

Systematic review and meta-analysis to examine intrapartum interventions, and maternal and neonatal outcomes following immersion in water during labour and waterbirth

OBJECTIVES

Water immersion during labour using a birth pool to achieve relaxation and pain relief during the first and possibly part of the second stage of labour is an increasingly popular care option in several countries. It is used particularly by healthy women who experience a straightforward pregnancy, labour spontaneously at term gestation and plan to give birth in a midwifery led care setting. More women are also choosing to give birth in water. There is debate about the safety of intrapartum water immersion, particularly waterbirth. We synthesised the evidence that compared the effect of water immersion during labour or waterbirth on intrapartum interventions and outcomes to standard care with no water immersion. A secondary objective was to synthesise data relating to clinical care practices and birth settings that women experience who immerse in water and women who do not.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

A search was conducted using CINAHL, Medline, Embase, BioMed Central and PsycINFO during March 2020 and was replicated in May 2021.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Primary quantitative studies published in 2000 or later, examining maternal or neonatal interventions and outcomes using the birthing pool for labour and/or birth.

DATA EXTRACTION AND SYNTHESIS

Full-text screening was undertaken independently against inclusion/exclusion criteria in two pairs. Risk of bias assessment included review of seven domains based on the Robbins-I Risk of Bias Tool. All outcomes were summarised using an OR and 95% CI. All calculations were conducted in Comprehensive Meta-Analysis V.3, using the inverse variance method. Results of individual studies were converted to log OR and SE for synthesis. Fixed effects models were used when I2 was less than 50%, otherwise random effects models were used. The fail-safe N estimates were calculated to determine the number of studies necessary to change the estimates. Begg's test and Egger's regression risk assessed risk of bias across studies. Trim-and-fill analysis was used to estimate the magnitude of effect of the bias. Meta-regression was completed when at least 10 studies provided data for an outcome.

RESULTS

We included 36 studies in the review, (N=157 546 participants). Thirty-one studies were conducted in an obstetric unit setting (n=70 393), four studies were conducted in midwife led settings (n=61 385) and one study was a mixed setting (OU and homebirth) (n=25 768). Midwife led settings included planned home and freestanding midwifery unit (k=1), alongside midwifery units (k=1), planned homebirth (k=1), a freestanding midwifery unit and an alongside midwifery unit (k=1) and an alongside midwifery unit (k=1). For water immersion, 25 studies involved women who planned to have/had a waterbirth (n=151 742), seven involved water immersion for labour only (1901), three studies reported on water immersion during labour and waterbirth (n=3688) and one study was unclear about the timing of water immersion (n=215).Water immersion significantly reduced use of epidural (k=7, n=10 993; OR 0.17 95% CI 0.05 to 0.56), injected opioids (k=8, n=27 391; OR 0.22 95% CI 0.13 to 0.38), episiotomy (k=15, n=36 558; OR 0.16; 95% CI 0.10 to 0.27), maternal pain (k=8, n=1200; OR 0.24 95% CI 0.12 to 0.51) and postpartum haemorrhage (k=15, n=63 891; OR 0.69 95% CI 0.51 to 0.95). There was an increase in maternal satisfaction (k=6, n=4144; OR 1.95 95% CI 1.28 to 2.96) and odds of an intact perineum (k=17, n=59 070; OR 1.48; 95% CI 1.21 to 1.79) with water immersion. Waterbirth was associated with increased odds of cord avulsion (OR 1.94 95% CI 1.30 to 2.88), although the absolute risk remained low (4.3 per 1000 vs 1.3 per 1000). There were no differences in any other identified neonatal outcomes.

CONCLUSIONS

This review endorses previous reviews showing clear benefits resulting from intrapartum water immersion for healthy women and their newborns. While most included studies were conducted in obstetric units, to enable the identification of best practice regarding water immersion, future birthing pool research should integrate factors that are known to influence intrapartum interventions and outcomes. These include maternal parity, the care model, care practices and birth setting.

Risk factors for postpartum hemorrhage in patients with retained placenta: building a predict model

OBJECTIVES

Among patients with placenta retention, the risk factors of massive blood loss remain unclear. In this study, a secondary data analysis was conducted to construct a predictive risk model for postpartum hemorrhage (PPH) in this particular population.

METHODS

A prediction model based on the data of 13 hospitals in the UK, Uganda, and Pakistan, from December 2004, to May 2008 was built. A total of 516 patients and 14 potential risk factors were analyzed. The least absolute shrinkage and selection operator regression (LASSO) model was used to optimize feature selection for the PPH risk model. Multivariable logistic regression analysis was applied to build a prediction model incorporating the LASSO model. Discrimination and calibration were assessed using C-index and calibration plot.

RESULTS

Among patients with placenta retention, the incidence of PPH was 62.98% (325/526). Risk factors in the model were country, number of past deliveries, previous manual removal of placenta, place of placenta delivery, and how the placenta was delivered. In these factors, patients in the low-income country (i.e., Uganda) (OR: 1.753, 95% CI=1.055-2.915), retained placentas delivered in the theater (OR: 2.028, 95% CI=1.016-4.050), and having placentas partially removed by controlled cord traction (cct), completely removed manually (OR: 4.722, 95% CI=1.280-17.417) were independent risk factors. The C-statistics was 0.702.

CONCLUSIONS

By secondary data analysis, our study constructed a prediction model for PPH in patients with placenta retention, and identified the independent risk factors.

Implementing Heat-Stable Carbetocin for Postpartum Haemorrhage Prevention in Low-Resource Settings: A Rapid Scoping Review

Heat-stable carbetocin (HSC), a long-acting oxytocin analogue that does not require cold-chain transportation and storage, is effective in preventing postpartum haemorrhage (PPH) in vaginal and caesarean deliveries in tertiary-care settings. We aimed to identify literature documenting how it is implemented in resource-limited and lower-level maternity care settings to inform policies and practices that enable its introduction in these contexts. A rapid scoping review was conducted with an 8-week timeframe by two reviewers. MEDLINE, EMBASE, Emcare, the Joanna Briggs Institute Evidence-Based Practice Database, the Maternity and Infant Care Database, and the Cochrane Library were searched for publications in English, French, and Spanish from January 2011 to September 2021. Randomized and non-randomized studies examining the feasibility, acceptability, and health system considerations in low-income and lower-middle-income countries were included. Relevant data were extracted using pretested forms, and results were synthesized descriptively. The search identified 62 citations, of which 12 met the eligibility criteria. The review did not retrieve studies focusing on acceptability and health system considerations to inform HSC implementation in low-resource settings. There were no studies located in rural or lower-level maternity settings. Two economic evaluations concluded that HSC is not feasible in terms of cost-effectiveness in lower-middle-income economies with private sector pricing, and a third one found superior care costs in births with PPH than without. The other nine studies focused on demonstrating HSC effectiveness for PPH prevention in tertiary hospital settings. There is a lack of evidence on the feasibility (beyond cost-effectiveness), acceptability, and health system considerations related to implementing HSC in resource-constrained and lower-level maternity facilities. Further implementation research is needed to help decision-makers and practitioners offer an HSC-inclusive intervention package to prevent excessive bleeding among pregnant women living in settings where oxytocin is not available or of dubious quality.

Umbilical cord clamping and management of the third stage of labor: A telephone-survey describing Swedish midwives’ clinical practice

INTRODUCTION

The timing of cord clamping impacts children’s short- and long-term well-being. When making clinical decisions, midwives incorporate their tacit and professional knowledge, experience and current evidence. There appears to be a lack of knowledge regarding Swedish midwives’ management of the third stage of labor and cord clamping practice. The aim of this study was to explore Swedish midwives’ clinical practice concerning umbilical cord clamping and the third stage of labor in spontaneous vaginal births.

METHODS

The study was designed as a cross-sectional telephone survey including 13 questions. Midwives were randomly selected from 48 births units in Sweden. Two midwives from each unit were interviewed. The primary outcome was timing of umbilical cord clamping practice in full-term infants. Secondary outcomes were the management of the third stage of labor including prophylactic use of synthetic oxytocin, the timing of cord clamping in preterm infants, controlled cord traction, uterine massage, and cord milking.

RESULTS

Altogether, 95 midwives were interviewed. In full-term infants, all midwives preferred late cord clamping. Considerable heterogeneity was seen regarding the practices of synthetic oxytocin administration postpartum, controlled cord traction, uterine massage or cord milking, and cord clamping in preterm infants.

CONCLUSIONS

Midwives in Sweden modify recommendations regarding delayed cord clamping in a way they might perceive as more natural and practical in their daily, clinical work. The study revealed a reluctance toward the administration of prophylactic oxytocin due to fear that the drug could pass to the infant. An overall large variation of the management of the third stage of labor was seen.

Pregnancy in special populations: challenges and solutions practical aspects of managing von Willebrand disease in pregnancy

Pregnancy and childbirth pose an important hemostatic challenge for women with von Willebrand disease (VWD) and can be associated with an increased risk of maternal and neonatal bleeding complications. VWD is a genetically and clinically heterogeneous bleeding disorder caused by a deficiency or an abnormality in the function of von Willebrand factor. Understanding inheritance pattern, hemostatic response to pregnancy, and response to treatment is essential for provision of individualized obstetric care and optimal outcome. A multidisciplinary approach to management with a close liaison between the obstetric team and the hemophilia treatment center is required for continuity of care from preconception counseling through to antenatal, peripartum, and postpartum care. Delivery plan must be coordinated by the multidisciplinary team and include decisions on place and mode of delivery, implementation of safe analgesia/anesthesia, and peripartum hemostasis. In this clinical case-based review, we aim to deliver evidence-based practical guidance for challenges encountered during pregnancy and management of childbirth and puerperium.

A study of the healthcare resource use for the management of postpartum haemorrhage in France, Italy, the Netherlands, and the UK

OBJECTIVE

Postpartum haemorrhage (PPH) complicates approximately 5% of births worldwide and is a leading direct cause of maternal death. Rates of PPH are increasing in many developed countries, particularly PPH related to uterine atony. There is a lack of published up-to-date information about healthcare resource use associated with management of PPH following vaginal birth. The objective of this study was to describe healthcare resource use for the management of minor PPH (blood loss 500-1,000 ml) and major PPH (blood loss > 1,000 ml) compared to uncomplicated birth (no PPH) following hospital vaginal birth in France, Italy, the Netherlands, and the UK.

STUDY DESIGN

In-depth interviews with two midwives from each participating country were conducted to establish differences in resource use for the management of minor PPH, major PPH, and uncomplicated birth. A web-survey was then developed and one obstetrician per participating country reviewed the survey. In total, 100 midwives (25 per country) completed the survey. Results were discussed at a multi-professional consensus meeting of midwives and obstetricians/gynaecologists (n = 6).

RESULTS AND CONCLUSIONS

Midwives participating in the survey estimated that 80% of women receive Active Management of the Third Stage of Labour (AMTSL) and 93% of participants specified that uterotonics would routinely be used during AMTSL. Most participants (84%) reported that blood loss is routinely measured in their hospital, using a combination of methods. PPH is associated with increased healthcare resource use, including administration of additional uterotonics and use of additional medical interventions, such as urinary catheter, intravenous fluids, and possible requirement for surgery. The number of nurses, obstetricians/gynaecologists, and anaesthetists involved in the management of PPH increases with the occurrence and severity of PPH, as well as the proportion of healthcare personnel providing continuous care. Women may spend an additional 24 h in hospital following major PPH compared to uncomplicated birth. The results of this study highlight the burden of PPH management on healthcare resources. To reduce costs associated with PPH, prevention is the most effective strategy and can be enhanced with the use of an effective uterotonic as part of the active management of the third stage of labour.

Sociodemographic and Clinical Factors Associated with Postpartum Hemorrhage in a Maternity Ward

Objective: Checking the sociodemographic and clinical factors associated with the prevalence of postpartum hemorrhage (PPH) in a maternity school. Materials and methods: A quantitative cross-sectional study in a maternity hospital in Salvador, Bahia, Brazil. In data collection, we used a standardized form that contained sociodemographic and clinical data from the medical records of 83 women for the period of 2018. Stata version 14 software was used in the analyses. Bivariate analysis was conducted using Pearson’s or Fisher’s exact tests. Poisson regression was performed with robust variation in multivariate analysis. Prevalence ratios (PR) and respective 95 % confidence intervals were estimated. The significance level of the tests was 5 %. Results: The prevalence of PPH was 38.6 % and 25.6 % for atony as the cause. In the bivariate analysis, there was an association between PPH and non-breastfeeding in the first hour of life (p = 0.039). In the multivariate analysis, it was identified that multiparous women had an increase in the prevalence of PPH by almost twice (PR = 1.97). Not breastfeeding in the first hour of life increased this prevalence more than four times (PR = 4.16). Conclusions: Monitoring multiparous women during birth care and encouraging breastfeeding in the first hour of life may decrease the prevalence of PPH.

Pan[dem]ic! Rational Risk Avoidance During a Health Pandemic

During a health pandemic health workers have to balance two competing objectives: their own welfare vs. that of their patients. Intuitively, attending to sick patients during a pandemic poses risks to health workers because some of these patients could be infected. One way to reduce risk is by reducing contact with patients. These changes could be on the extensive margin, e.g., seeing fewer patients; or, more insidiously, on the intensive margin, by reducing the duration/intensity of contact. This paper studies risk avoidance behavior during the Covid-19 pandemic and examines implications for patient welfare. Using primary data on thousands of patient-provider interactions between January 2019 and October 2020 in Nigeria, I present evidence of risk compensation by health workers along the intensive margin. For example, the probability that a patient receives a physical examination has dropped by about a third. I find suggestive evidence of negative effects on health outcomes.

Implementation of Delayed Cord Clamping for 3 Min During Term Cesarean Sections Does Not Influence Maternal Blood Loss

Background: To assess maternal safety outcomes after a local protocol adjustment to change the interval of cord clamping to 3 min after term cesarean section. Design, Setting, and Patients: A retrospective cohort study in a tertiary referral hospital (Erasmus MC, Rotterdam). We included pregnant women who gave birth at term after cesarean section. A cohort (Nov 2016-Oct 2017) prior to the protocol implementation was compared to a cohort after its implementation (Nov 2017-Nov 2018). The study population covered 789 women (n = 376 pre-cohort; n = 413 post-cohort). Interventions: Implementation of a local protocol changing the interval of cord clamping to 3 min in all term births. Main outcome measures: Primary outcomes were the estimated maternal blood loss and the occurrence of postpartum hemorrhage (blood loss >1,000 ml). Secondary outcomes included both maternal as well as neonatal outcomes. Results: Estimated maternal blood loss was not significantly different between the pre-cohort and post-cohort (400 mL [300-600] vs. 400 mL [300-600], p = 0.52). The incidence of postpartum hemorrhage (26 [6.9%] vs. 35 (8.5%), OR 1.24, 95% CI 0.73-2.11) and maternal blood transfusion (9 [2%] vs. 13 (3%), OR 1.33, 95% CI 0.56-3.14) were not different. Hemoglobin change was significantly higher in the post-cohort (-0.8 mmol/L [-1.3 to -0.5] vs. -0.9 mmol/L [-1.4 to -0.6], p = 0.01). In the post-cohort, neonatal hematocrit levels were higher (51 vs. 55%, p = 0.004) and need for phototherapy was increased (OR 1.95, 95% CI 0.99-3.84). Conclusion: Implementation of delayed cord clamping for 3 min in term cesarean sections was not associated with increased maternal bleeding complications.

Does Delayed Cord Clamping Improve Long-Term (≥4 Months) Neurodevelopment in Term Babies? A Systematic Review and a Meta-Analysis of Randomized Clinical Trials

Background: Recently, the literature suggested that placental transfusion facilitated by delayed cord clamping (DCC), besides having benefits on hematological parameters, might improve the infants' brain development. Objective: The present review primarily evaluates the Ages and Stages Questionnaire (ASQ) total score mean difference (MD) at long-term follow-up (≥4 months) comparing DCC (>90 or >180 s) to early cord clamping (ECC). Secondary aims consisted of evaluating the ASQ domains' MD and the results obtained from other methods adopted to evaluate the infants' neurodevelopment. Methods: MEDLINE, Scopus, Cochrane, and ClinicalTrials.gov databases were searched (up to 2nd November 2020) for systematic review and meta-analysis. All randomized controlled trials (RCTs) of term singleton gestations received DCC or ECC. Multiple pregnancies, pre-term delivery, non-randomized studies, and articles in languages other than English were excluded. The included studies were assessed for bias and quality. ASQ data were pooled stratified by time to follow up. Results: This meta-analysis of 4 articles from 3 RCTs includes 765 infants with four-month follow-up and 672 with 12 months follow-up. Primary aim (ASQ total score) pooled analysis was possible only for 12 months follow-up, and no differences were found between DCC and ECC (MD 1.1; CI 95: -5.1; 7.3). DCC approach significantly improves infants' communication domains (MD 0.6; CI 95: 0.1; 1.1) and personal-social assessed (MD 1.0; CI 95: 0.3; 1.6) through ASQ at 12 months follow-up. Surprisingly, the four-month ASQ personal social domain (MD -1.6; CI 95: -2.8; -0.4) seems to be significantly lower in the DCC group than in the ECC group. Conclusions: DCC, a simple, non-interventional, and cost-effective approach, might improve the long-term infants' neurological outcome. Single-blinding and limited studies number were the main limitations. Further research should be performed to confirm these observations, ideally with RCTs adopting standard methods to assess infants' neurodevelopment.

Prospective cohort study of water immersion for labour and birth compared with standard care in an Irish maternity setting

OBJECTIVE

To examine the birth outcomes for women and babies following water immersion for labour only, or for labour and birth.

DESIGN

Prospective cohort study.

SETTING

Maternity hospital, Ireland, 2016-2019.

PARTICIPANTS

A cohort of 190 low-risk women who used water immersion; 100 gave birth in water and 90 laboured only in water. A control group of 190 low-risk women who received standard care.

METHODS

Logistic regression analyses examined associations between water immersion and birth outcomes adjusting for confounders. A validated Childbirth Experience Questionnaire was completed.

MAIN OUTCOME MEASURES

Perineal tears, obstetric anal sphincter injuries (OASI), postpartum haemorrhage (PPH), neonatal unit admissions (NNU), breastfeeding and birth experiences.

RESULTS

Compared with standard care, women who chose water immersion had no significant difference in perineal tears (71.4% vs 71.4%, adj OR 0.83; 95% CI 0.49 to 1.39) or in OASI (3.3% vs 3.8%, adj OR 0.91; 0.26-2.97). Women who chose water immersion were more likely to have a PPH ≥500 mL (10.5% vs 3.7%, adj OR 2.60; 95% CI 1.03 to 6.57), and to exclusively breastfeed at discharge (71.1% vs 45.8%, adj OR 2.59; 95% CI 1.66 to 4.05). There was no significant difference in NNU admissions (3.7% vs 3.2%, adj OR 1.06; 95% CI 0.33 to 3.42). Women who gave birth in water were no more likely than women who used water for labour only to require perineal suturing (64% vs 80.5%, adj OR 0.63; 95% CI 0.30 to 1.33), to experience OASI (3.0% vs 3.7%, adj OR 1.41; 95% CI 0.23 to 8.79) or PPH (8.0% vs 13.3%, adj OR 0.73; 95% CI 0.26 to 2.09). Women using water immersion reported more positive memories than women receiving standard care (p<0.01).

CONCLUSIONS

Women choosing water immersion for labour or birth were no more likely to experience adverse birth outcomes than women receiving standard care and rated their birth experiences more highly.

Using a mobile nurse mentoring and training program to address a health workforce capacity crisis in Bihar, India: Impact on essential intrapartum and newborn care practices

BACKGROUND

To address a health workforce capacity crisis, in coordination with the Government of Bihar, CARE India implemented an on-the-job, on-site nurse mentoring and training intervention named - Apatkalin Matritva evam Navjat Tatparta (AMANAT, translated Emergency Maternal and Neonatal Care Preparedness) - in public facilities in Bihar. AMANAT was rolled-out in a phased manner to provide hands-on training and mentoring for nurses and doctors offering emergency obstetric and newborn care (EmONC) services. This study examines the impact of the AMANAT intervention on nurse-mentees' competency to provide such services in Bihar, India during 2015-2017.

METHODS

We used data from three AMANAT implementation phases, each covering 80 public facilities offering basic EmONC services. Before and after the intervention, CARE India administered knowledge assessments to nurse-mentees; ascertained infection control practices at the facility level; and used direct observation of deliveries to assess nurse-mentees' practices. We examined changes in nurse-mentees' knowledge scores using χ2 tests for proportions and t tests for means; and estimated proportions and corresponding 95% confidence intervals for routine performance of infection control measures, essential intrapartum and newborn services. We fitted linear regression models to explore the impact of the intervention on nurse-mentees' knowledge and practices after adjusting for potential confounders.

RESULTS

On average, nurse-mentees answered correctly 38% of questions at baseline and 68% of questions at endline (P < 0.001). All nine infection control measures assessed were significantly more prevalent at endline (range 28.8%-86.8%) than baseline. We documented statistically significant improvements in 18 of 22 intrapartum and 9 of 13 newborn care practices (P < 0.05). After controlling for potential confounders, we found that the AMANAT intervention led to significant improvements in nurse-mentees' knowledge (30.1%), facility-level infection control (30.8%), intrapartum (29.4%) and newborn management (24.2%) practices (all P < 0.05). Endline scores ranged between 56.8% and 72.8% of maximum scores for all outcomes.

CONCLUSION

The AMANAT intervention had significant results in a health workforce capacity crisis situation, when a large number of auxiliary nurse-midwives were expected to provide services for which they lacked the necessary skills. Gaps in intrapartum and newborn care knowledge and practice still exist in Bihar and should be addressed through future mentoring and training interventions.

Intravenous versus intramuscular prophylactic oxytocin for the third stage of labour

BACKGROUND

There is general agreement that oxytocin given either through the intravenous or intramuscular route is effective in reducing postpartum blood loss. However, it is unclear whether the subtle differences between the mode of action of these routes have any effect on maternal and infant outcomes. This review was first published in 2012 and last updated in 2018.

OBJECTIVES

To determine the comparative effectiveness and safety of oxytocin administered intravenously or intramuscularly for prophylactic management of the third stage of labour after vaginal birth.

SEARCH METHODS

We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (19 December 2019), and reference lists of retrieved studies.

SELECTION CRITERIA

Eligible studies were randomised trials comparing intravenous with intramuscular oxytocin for prophylactic management of the third stage of labour after vaginal birth. We excluded quasi-randomised trials.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion and risk of bias, extracted data and checked them for accuracy. We assessed the certainty of the evidence with the GRADE approach.

MAIN RESULTS

Seven trials, involving 7817 women, met the inclusion criteria for this review. The trials compared intravenous versus intramuscular administration of oxytocin just after the birth of the anterior shoulder or soon after the birth of the baby. All trials were conducted in hospital settings and included women with term pregnancies, undergoing a vaginal birth. Overall, the included studies were at moderate or low risk of bias, with two trials providing clear information on allocation concealment and blinding. For GRADE outcomes, the certainty of the evidence was generally moderate to high, except from two cases where the certainty of the evidence was either low or very low. High-certainty evidence suggests that intravenous administration of oxytocin in the third stage of labour compared with intramuscular administration carries a lower risk for postpartum haemorrhage (PPH) ≥ 500 mL (average risk ratio (RR) 0.78, 95% confidence interval (CI) 0.66 to 0.92; six trials; 7731 women) and blood transfusion (average RR 0.44, 95% CI 0.26 to 0.77; four trials; 6684 women). Intravenous administration of oxytocin probably reduces the risk of PPH ≥ 1000 mL, although the 95% CI crosses the line of no-effect (average RR 0.65, 95% CI 0.39 to 1.08; four trials; 6681 women; moderate-certainty evidence). In all studies but one, there was a reduction in the risk of PPH ≥ 1000 mL with intravenous oxytocin. The study that found a large increase with intravenous administration was small (256 women), and contributed only 3% of total events. Once this small study was removed from the meta-analysis, heterogeneity was eliminated and the treatment effect favoured intravenous oxytocin (average RR 0.61, 95% CI 0.42 to 0.88; three trials; 6425 women; high-certainty evidence). Additionally, a sensitivity analysis, exploring the effect of risk of bias by restricting analysis to those studies rated as 'low risk of bias' for random sequence generation and allocation concealment, found that the prophylactic administration of intravenous oxytocin reduces the risk for PPH ≥ 1000 mL, compared with intramuscular oxytocin (average RR 0.64, 95% CI 0.43 to 0.94; two trials; 1512 women). The two routes of oxytocin administration may be comparable in terms of additional uterotonic use (average RR 0.78, 95% CI 0.49 to 1.25; six trials; 7327 women; low-certainty evidence). Although intravenous compared with intramuscular administration of oxytocin probably results in a lower risk for serious maternal morbidity (e.g. hysterectomy, organ failure, coma, intensive care unit admissions), the confidence interval suggests a substantial reduction, but also touches the line of no-effect. This suggests that there may be no reduction in serious maternal morbidity (average RR 0.47, 95% CI 0.22 to 1.00; four trials; 7028 women; moderate-certainty evidence). Most events occurred in one study from Ireland reporting high dependency unit admissions, whereas in the remaining three studies there was only one case of uvular oedema. There were no maternal deaths reported in any of the included studies (very low-certainty evidence). There is probably little or no difference in the risk of hypotension between intravenous and intramuscular administration of oxytocin (RR 1.01, 95% CI 0.88 to 1.15; four trials; 6468 women; moderate-certainty evidence). Subgroup analyses based on the mode of administration of intravenous oxytocin (bolus injection or infusion) versus intramuscular oxytocin did not show any substantial differences on the primary outcomes. Similarly, additional subgroup analyses based on whether oxytocin was used alone or as part of active management of the third stage of labour (AMTSL) did not show any substantial differences between the two routes of administration.

AUTHORS' CONCLUSIONS

Intravenous administration of oxytocin is more effective than its intramuscular administration in preventing PPH during vaginal birth. Intravenous oxytocin administration presents no additional safety concerns and has a comparable side effects profile with its intramuscular administration. Future studies should consider the acceptability, feasibility and resource use for the intervention, especially in low-resource settings.

Perspective of the comparative effectiveness of non-pharmacologic managements on postpartum hemorrhage using a network meta-analysis

OBJECTIVE

Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide and is both unpredictable and inevitable. While uterotonic drugs are routinely recommended, there is ongoing debate on the ideal intervention to control uterine bleeding. This review aims to compare the use of non-pharmacologic treatments with peripartum hysterectomy in cases of life-threatening uncontrolled obstetric hemorrhage. The review's objective is to use a network meta-analysis to help prevent maternal deaths and rank the treatments according to success rates.

METHODS

We searched MEDLINE (PubMed), Embase, and the Cochrane Library, from January 2014 until December 2018. A second search was carried out in April 2019 before the final data analysis. Network meta-analysis allows for the calculation of the effect size between treatment groups through indirect treatment comparison.

RESULTS

We confirmed that balloon-assisted management is the best intervention for uncontrolled postpartum bleeding with pharmacologic treatment. This is followed by uterine artery embolization and surgical procedures, which can help avoid the need for a hysterectomy. The balloon tamponade demonstrated lower failure rate than the surgical procedure with odds ratio (OR) of 0.44 and 95% confidence intervals (CIs) 0.50-30.54. Uterine artery embolization had a lower risk for hysterectomy than the surgical procedure group (OR, 0.74; 95% CI, 0.22-2.50).

CONCLUSION

For the quick treatment of postpartum bleeding, balloon tamponade is the best method for uncontrolled postpartum bleeding with pharmacologic treatment, followed by uterine artery embolization and surgical procedures.

How do midwives facilitate women to give birth during physiological second stage of labour? A systematic review

Both nationally and internationally, midwives' practices during the second stage of labour vary. A midwife's practice can be influenced by education and cultural practices but ultimately it should be informed by up-to-date scientific evidence. We conducted a systematic review of the literature to retrieve evidence that supports high quality intrapartum care during the second stage of labour. A systematic literature search was performed to September 2019 in collaboration with a medical information specialist. Bibliographic databases searched included: PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, Maternity and Infant Care Database and The Cochrane Library, resulting in 6,382 references to be screened after duplicates were removed. Articles were then assessed for quality by two independent researchers and data extracted. 17 studies focusing on midwives' practices during physiological second stage of labour were included. Two studies surveyed midwives regarding their practice and one study utilising focus groups explored how midwives facilitate women's birthing positions, while another focus group study explored expert midwives' views of their practice of preserving an intact perineum during physiological birth. The remainder of the included studies were primarily intervention studies, highlighting aspects of midwifery practice during the second stage of labour. The empirical findings were synthesised into four main themes namely: birthing positions, non-pharmacological pain relief, pushing techniques and optimising perineal outcomes; the results were outlined and discussed. By implementing this evidence midwives may enable women during the second stage of labour to optimise physiological processes to give birth. There is, however, a dearth of evidence relating to midwives' practice, which provides a positive experience for women during the second stage of labour. Perhaps this is because not all midwives' practices during the second stage of labour are researched and documented. This systematic review provides a valuable insight of the empirical evidence relating to midwifery practice during the physiological second stage of labour, which can also inform education and future research. The majority of the authors were members of the EU COST Action IS1405: Building Intrapartum Research Through Health (BIRTH). The study protocol is registered in the International Prospective Register of Systematic Reviews (PROSPERO; Registration CRD42018088300) and is published (Verhoeven, Spence, Nyman, Otten, Healy, 2019).

Epidemiology of Oxytocin Administration in Out-of-Hospital Births Attended by Paramedics

AIM

Primary postpartum hemorrhage (PPH) is a life-threatening obstetric emergency that can be mitigated through the administration of a uterotonic to actively manage the third stage of labor. This study describes the prehospital administration of oxytocin by paramedics following attendance of out-of-hospital (OOH) births.

METHODS

A retrospective analysis was undertaken of all OOH births between the 1^st January 2018 and 31^st December 2018 attended by the Queensland Ambulance Service. The demographic and epidemiological characteristics of patients that were administered oxytocin and the occurrence of adverse side effects were described.

RESULTS

In total, 350 OOH births were included in this study with the majority involving multigravidas women (94.3%) and all but two involving singleton pregnancies. Oxytocin was administered following 222 births (63.4%), while 67 patients (19.1%) declined administration preferring a physiological third stage of labor, and in 61 cases (17.4%) oxytocin was withheld by the attending paramedic. There were no documented adverse events or side effects following administration. Oxytocin administration occurred on average 14 minutes (interquartile range 9-25) following the time of birth. The median time from oxytocin administration to placenta delivery was 10 minutes (interquartile range 5-22).

CONCLUSION

Oxytocin is well accepted and safe treatment adjunct for the management of the third stage of labor in OOH births and should be considered for routine practice by other emergency medical services.

Mechanical and surgical interventions for treating primary postpartum haemorrhage

BACKGROUND

Primary postpartum haemorrhage (PPH) is commonly defined as bleeding from the genital tract of 500 mL or more within 24 hours of birth. It is one of the most common causes of maternal mortality worldwide and causes significant physical and psychological morbidity. An earlier Cochrane Review considering any treatments for the management of primary PPH, has been split into separate reviews. This review considers treatment with mechanical and surgical interventions.

OBJECTIVES

To determine the effectiveness and safety of mechanical and surgical interventions used for the treatment of primary PPH.

SEARCH METHODS

We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (26 July 2019) and reference lists of retrieved studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of mechanical/surgical methods for the treatment of primary PPH compared with standard care or another mechanical/surgical method. Interventions could include uterine packing, intrauterine balloon insertion, artery ligation/embolism, or uterine compression (either with sutures or manually). We included studies reported in abstract form if there was sufficient information to permit risk of bias assessment. Trials using a cluster-RCT design were eligible for inclusion, but quasi-RCTs or cross-over studies were not.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion and risk of bias, independently extracted data and checked data for accuracy. We used GRADE to assess the certainty of the evidence.

MAIN RESULTS

We included nine small trials (944 women) conducted in Pakistan, Turkey, Thailand, Egypt (four trials), Saudi Arabia, Benin and Mali. Overall, included trials were at an unclear risk of bias. Due to substantial differences between the studies, it was not possible to combine any trials in meta-analysis. Many of this review's important outcomes were not reported. GRADE assessments ranged from very low to low, with the majority of outcome results rated as very low certainty. Downgrading decisions were mainly based on study design limitations and imprecision; one study was also downgraded for indirectness. External uterine compression versus normal care (1 trial, 64 women) Very low-certainty evidence means that we are unclear about the effect on blood transfusion (risk ratio (RR) 2.33, 95% confidence interval (CI) 0.66 to 8.23). Uterine arterial embolisation versus surgical devascularisation plus B-Lynch (1 trial, 23 women) The available evidence for hysterectomy to control bleeding (RR 0.73, 95% CI 0.15 to 3.57) is unclear due to very low-certainty evidence. The available evidence for intervention side effects is also unclear because the evidence was very low certainty (RR 1.09; 95% CI 0.08 to 15.41). Intrauterine Tamponade Studies included various methods of intrauterine tamponade: the commercial Bakri balloon, a fluid-filled condom-loaded latex catheter ('condom catheter'), an air-filled latex balloon-loaded catheter ('latex balloon catheter'), or traditional packing with gauze. Balloon tamponade versus normal care (2 trials, 356 women) One study(116 women) used the condom catheter. This study found that it may increase blood loss of 1000 mL or more (RR 1.52, 95% CI 1.15 to 2.00; 113 women), very low-certainty evidence. For other outcomes the results are unclear and graded as very low-certainty evidence: mortality due to bleeding (RR 6.21, 95% CI 0.77 to 49.98); hysterectomy to control bleeding (RR 4.14, 95% CI 0.48 to 35.93); total blood transfusion (RR 1.49, 95% CI 0.88 to 2.51); and side effects. A second study of 240 women used the latex balloon catheter together with cervical cerclage. Very low-certainty evidence means we are unclear about the effect on hysterectomy (RR 0.14, 95% CI 0.01 to 2.74) and additional surgical interventions to control bleeding (RR 0.20, 95% CI 0.01 to 4.12). Bakri balloon tamponade versus haemostatic square suturing of the uterus (1 trial, 13 women) In this small trial there was no mortality due to bleeding, serious maternal morbidity or side effects of the intervention, and the results are unclear for blood transfusion (RR 0.57, 95% CI 0.14 to 2.36; very low certainty). Bakri balloon tamponade may reduce mean 'intraoperative' blood loss (mean difference (MD) -426 mL, 95% CI -631.28 to -220.72), very low-certainty evidence. Comparison of intrauterine tamponade methods (3 trials, 328 women) One study (66 women) compared the Bakri balloon and the condom catheter, but it was uncertain whether the Bakri balloon reduces the risk of hysterectomy to control bleeding due to very low-certainty evidence (RR 0.50, 95% CI 0.05 to 5.25). Very low-certainty evidence also means we are unclear about the results for the risk of blood transfusion (RR 0.97, 95% CI 0.88 to 1.06). A second study (50 women) compared Bakri balloon, with and without a traction stitch. Very low-certainty evidence means we are unclear about the results for hysterectomy to control bleeding (RR 0.20, 95% CI 0.01 to 3.97). A third study (212 women) compared the condom catheter to gauze packing and found that it may reduce fever (RR 0.47, 95% CI 0.38 to 0.59), but again the evidence was very low certainty. Modified B-Lynch compression suture versus standard B-Lynch compression suture (1 trial, 160 women) Low-certainty evidence suggests that a modified B-Lynch compression suture may reduce the risk of hysterectomy to control bleeding (RR 0.33, 95% CI 0.11 to 0.99) and postoperative blood loss (MD -244.00 mL, 95% CI -295.25 to -192.75).

AUTHORS' CONCLUSIONS

There is currently insufficient evidence from RCTs to determine the relative effectiveness and safety of mechanical and surgical interventions for treating primary PPH. High-quality randomised trials are urgently needed, and new emergency consent pathways should facilitate recruitment. The finding that intrauterine tamponade may increase total blood loss > 1000 mL suggests that introducing condom-balloon tamponade into low-resource settings on its own without multi-system quality improvement does not reduce PPH deaths or morbidity. The suggestion that modified B-Lynch suture may be superior to the original requires further research before the revised technique is adopted. In high-resource settings, uterine artery embolisation has become popular as the equipment and skills become more widely available. However, there is little randomised trial evidence regarding efficacy and this requires further research. We urge new trial authors to adopt PPH core outcomes to facilitate consistency between primary studies and subsequent meta-analysis.

Implementation of a Postpartum Hemorrhage Safety Bundle at an Urban Safety-Net Hospital

Background  Postpartum hemorrhage (PPH) is a leading cause of preventable maternal morbidity and mortality. Standardized response to obstetric hemorrhage is associated with significant improvement in maternal outcomes, yet implementation can be challenging. Objective  The primary objective is to describe the methodology for program implementation of the Alliance for Innovation on Maternal Health Safety Bundle on PPH at an urban safety-net hospital. Methods  Over an 18-month period, interventions geared toward (1) risk assessment and stratification, (2) hemorrhage identification and management, (3) team communication and simulation, and (4) debriefs and case review were implemented. Hemorrhage risk assessment stratification rates were tracked overtime as an early measure of bundle compliance. Results  Hemorrhage risk assessment stratification rates improved to >90% during bundle implementation. Conclusion  Keys to implementation included multidisciplinary stakeholder commitment, stepwise and iterative approach, and parallel systems for monitoring and evaluation Implementation of a PPH safety bundle is feasible in a resource-constrained setting.

Carbetocin versus oxytocin for prevention of postpartum hemorrhage in hypertensive women undergoing elective cesarean section

OBJECTIVE

Assess the efficacy and safety of carbetocin, versus oxytocin in the prevention of postpartum hemorrhage in hypertensive women.

STUDY DESIGN

A randomized clinical trial.

SETTING

Obstetrics and Gynecology Department of Suez Canal University Hospital.

PATIENTS

One hundred and sixty hypertensive pregnant women who underwent CS.

INTERVENTIONS

Patients were randomized to receive either 10 IU oxytocin or 100 μg carbetocin. Primary outcomes included estimated blood loss, blood transfusion, hemoglobin (HB), and hematocrit changes pre- and post-delivery and the use of additional uterotonics.

RESULTS

The postoperative HB was not different from preoperative HB in the carbetocin group (11.8 ± 1.2 vs. 11.2 ± 1.2 g/dL) while it decreased significantly in the oxytocin group (12.1 ± 3.8 vs. 10.4 ± 1.1 g/dL, p < 0.001). Blood loss was significantly more among the oxytocin group (679.5 ± 200.25 vs. 424.75 ± 182.59 ml) in the carbetocin group (p < 0.001). Nausea, vomiting, and sweating were reported more significantly in oxytocin group patients.

CONCLUSION

Carbetocin was more effective than oxytocin in reducing intraoperative and postoperative blood loss.

Effect of timing of umbilical cord clamping and other strategies to influence placental transfusion at preterm birth on maternal and infant outcomes

BACKGROUND

Infants born preterm (before 37 weeks' gestation) have poorer outcomes than infants at term, particularly if born before 32 weeks. Early cord clamping has been standard practice over many years, and enables quick transfer of the infant to neonatal care. Delayed clamping allows blood flow between the placenta, umbilical cord and baby to continue, and may aid transition. Keeping baby at the mother's side enables neonatal care with the cord intact and this, along with delayed clamping, may improve outcomes. Umbilical cord milking (UCM) is proposed for increasing placental transfusion when immediate care for the preterm baby is needed. This Cochrane Review is a further update of a review first published in 2004 and updated in 2012.

OBJECTIVES

To assess the effects on infants born at less than 37 weeks' gestation, and their mothers of: 1) delayed cord clamping (DCC) compared with early cord clamping (ECC) both with immediate neonatal care after cord clamping; 2) DCC with immediate neonatal care with cord intact compared with ECC with immediate neonatal care after cord clamping; 3) DCC with immediate neonatal care after cord clamping compared with UCM; 4) UCM compared with ECC with immediate neonatal care after cord clamping.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (10 November 2017), and reference lists of retrieved studies. We updated the search in November 2018 and added nine new trial reports to the awaiting classification section to be assessed at the next update.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing delayed with early clamping of the umbilical cord (with immediate neonatal care after cord clamping or with cord intact) and UCM for births before 37 weeks' gestation. Quasi-RCTs were excluded.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Random-effects are used in all meta-analyses. Review authors assessed the certainty of the evidence using the GRADE approach.

MAIN RESULTS

This update includes forty-eight studies, involving 5721 babies and their mothers, with data available from 40 studies involving 4884 babies and their mothers. Babies were between 24 and 36+6 weeks' gestation at birth and multiple births were included. The data are mostly from high-income countries. Delayed clamping ranged between 30 to 180 seconds, with most studies delaying for 30 to 60 seconds. Early clamping was less than 30 seconds and often immediate. UCM was mostly before cord clamping but some were milked after cord clamping. We undertook subgroup analysis by gestation and type of intervention, and sensitivity analyses by low risk of selection and attrition bias.All studies were high risk for performance bias and many were unclear for other aspects of risk of bias. Certainty of the evidence using GRADE was mostly low, mainly due to imprecision and unclear risk of bias.Delayed cord clamping (DCC) versus early cord clamping (ECC) both with immediate neonatal care after cord clamping (25 studies, 3100 babies and their mothers)DCC probably reduces the number of babies who die before discharge compared with ECC (average risk ratio (aRR) 0.73, 95% confidence interval (CI) 0.54 to 0.98, 20 studies, 2680 babies (moderate certainty)).No studies reported on 'Death or neurodevelopmental impairment' in the early years'.DCC may make little or no difference to the number of babies with severe intraventricular haemorrhage (IVH grades 3 and 4) (aRR 0.94, 95% CI 0.63 to 1.39, 10 studies, 2058 babies, low certainty) but slightly reduces the number of babies with any grade IVH (aRR 0.83, 95% CI 0.70 to 0.99, 15 studies, 2333 babies, high certainty).DCC has little or no effect on chronic lung disease (CLD) (aRR 1.04, 95% CI 0.94 to 1.14, 6 studies, 1644 babies, high certainty).Due to insufficient data, we were unable to form conclusions regarding periventricular leukomalacia (PVL) (aRR 0.58, 95% CI 0.26 to 1.30, 4 studies, 1544 babies, low certainty) or maternal blood loss of 500 mL or greater (aRR 1.14, 95% CI 0.07 to 17.63, 2 studies, 180 women, very low certainty).We identified no important heterogeneity in subgroup or sensitivity analyses.Delayed cord clamping (DCC) with immediate neonatal care with cord intact versus early cord clamping (ECC) (one study, 276 babies and their mothers)There are insufficient data to be confident in our findings, but DCC with immediate neonatal care with cord intact may reduce the number of babies who die before discharge, although the data are also compatible with a slight increase in mortality, compared with ECC (aRR 0.47, 95% CI 0.20 to 1.11, 1 study, 270 babies, low certainty). DCC may also reduce the number of babies who die or have neurodevelopmental impairment in early years (aRR 0.61, 95% CI 0.39 to 0.96, 1 study, 218 babies, low certainty). There may be little or no difference in: severe IVH; all grades IVH; PVL; CLD; maternal blood loss ≥ 500 mL, assessed as low certainty mainly due to serious imprecision.Delayed cord clamping (DCC) with immediate neonatal care after cord clamping versus umbilical cord milking (UCM) (three studies, 322 babies and their mothers) and UCM versus early cord clamping (ECC) (11 studies, 1183 babies and their mothers)There are insufficient data for reliable conclusions about the comparative effects of UCM compared with delayed or early clamping (mostly low or very low certainty).

AUTHORS' CONCLUSIONS

Delayed, rather than early, cord clamping may reduce the risk of death before discharge for babies born preterm. There is insufficient evidence to show what duration of delay is best, one or several minutes, and therefore the optimum time to clamp the umbilical cord remains unclear. Whilst the current evidence supports not clamping the cord before 30 seconds at preterm births, future trials could compare different lengths of delay. Immediate neonatal care with the cord intact requires further study, and there are insufficient data on UCM.The nine new reports awaiting further classification may alter the conclusions of the review once assessed.
