Continuous versus interrupted perineal repair with standard or rapidly absorbed sutures after spontaneous vaginal birth: a randomised controlled trial

The impact of different skin Suture methods in episiotomy repair on healing and pain: A randomized clinical trial

We conducted a randomized clinical trial at a tertiary center between March and August 2022. We enrolled primiparous women aged 18-45 years requiring an episiotomy. Skin closure of the episiotomy was performed using three suture techniques: mattress, primary interrupted, and subcutaneous. Evaluation of healing and pain was carried out using Visual Analog Scale (VAS) and Redness, Edema, Ecchymosis, Discharge, and Approximation (REEDA) scores on the first and fifteenth postpartum days. The interrupted and subcutaneous groups showed significantly lower VAS scores on the first postpartum day compared to the mattress group (p < 0.001). The duration of mattress suturing was longer than that of interrupted or subcutaneous suturing (p = 0.044). On the fifteenth postpartum day, the subcutaneous group demonstrated lower REEDA scores compared to the other groups (p = 0.013). The subcutaneous continuous suturing group exhibited superior healing compared to the primary interrupted and mattress groups on the fifteenth postpartum day.

Localized Nanoindentation Paradigm for Revealing Sutured Tissue Interface Mechanics and Integrity

This study investigates the nanoindentation technique to elucidate the quasi-static and dynamic stress response at the wounded and sutured tissue interface. In vitro modeling and wound healing analysis enable an understanding of sutured tissue interface integrity, modulus, and stability using an artificial abdominal wall model. Sutured tissues with simple interrupted suturing (SIS) demonstrated a 35-40% higher modulus than simple continuous suturing (SCS). High-density suturing with a suture space of 2.5 mm exhibited a 2-fold higher modulus than low-density suturing with a suture space of 5 mm. The elastic modulus of the sutured pad immersed in deionized water was ∼70-95% of the dry condition. The dynamic stress data indicate that long-term body motions-triggered stress instability at the wound interface was affected by suturing style and density. The pivotal factors determining wound healing are quasi-static and dynamic modulus at the sutured interface, which is intimately associated with patient pain, wound complications, healing speed, and blood flow. The proposed method and data are an original approach to addressing wound healing, contributing to patient well-being and identifying, interpreting, and breaking the drawn-out debates in the suturing field.

Continuous non-locking vs. interrupted suturing techniques for the repair of episiotomy or second-degree perineal tears: A single-blind randomized controlled trial

Objective

Perineal trauma is a serious and frequent problem after childbirth which is experienced by millions of women worldwide. The technique used for perineal repair may have an impact on pain and wound healing. The aim of the present study was to compare the continuous non-locking technique with interrupted suturing for the repair of episiotomy or second-degree perineal tears.

Methods

A single-blind randomized-controlled trial was conducted from October 2021 to August 2022 in Sina Hospital, Ahvaz, Iran. Three hundred women were selected and randomly assigned into control and intervention groups using block randomization technique. The main outcomes included pain and wound healing that were assessed using visual analog scale (VAS), as well as redness, edema, ecchymosis/bruising, discharge, and approximation scale (REEDA). The secondary outcomes were the use of analgesics, duration of perineal repair, material used for suturing, pain during urination and defecation, and resumption of sexual intercourse. The participants were followed up on the first and seventh days and in the 6th week postpartum. Mann-Whitney, Chi-square, and Generalized Estimating Equations (GEE) model were used for data analysis.

Results

Wound healing was significantly better in the continuous non-locking suture technique compared to the interrupted technique (β = -1.98; P > 0.0001). Women also experienced less pain in the continuous non-locking suture technique (β = -2.46; P > 0.0001). There was a reduction in the use of analgesics, the duration of perineal repair, and the material used for suturing in the continuous non-locking suturing technique as opposed to the interrupted method (P < 0.0001).The odds of pain during urination and defecation significantly reduced in women who underwent the continuous non-locking method (P < 0.001). Also, women in the continuous non-locking group resumed their sexual intercourse earlier (P < 0.0001).

Conclusion

The findings of this study revealed that use of continuous non-locking technique for suturing was associated with reduced perineal pain and improved wound healing. Furthermore, it was associated with a shorter duration of perineal repair, less suture material used, and less need for analgesics compared with the interrupted method. There is, however, need for more studies to confirm the results of the present study.Iranian registry for randomized controlled trials (Ref. ID: IRCT20190415043283N1).

Postpartum Dyspareunia Following Continuous Versus Interrupted Perineal Repair: A Systematic Review and Meta-Analysis

Research evaluating optimal repair techniques for the reduction of postpartum dyspareunia following obstetric laceration is severely limited. Prevailing guidelines from the American College of Obstetricians and Gynecologists (ACOG) are reliant on data from just nine clinical trials conducted from 1980 to 2012. While the literature on this topic is still limited today, this review aims to synthesize data from past and present studies to ensure that standing clinical recommendations are supported by current literature. A review was conducted per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Medical Literature Analysis and Retrieval System Online (MEDLINE), Cochrane Library, and Google Scholar were searched. Included articles (1) compared continuous with interrupted repair techniques for subjects with episiotomies and/or second-degree tears, (2) were available in full length, and (3) reported dyspareunia as an outcome variable. Excluded articles were those (1) inclusive of first-, third-, or fourth-degree tears; (2) comparing suture material rather than technique; and (3) not available in English. A meta-analysis was conducted for both acute dyspareunia (<3 months) and chronic dyspareunia (>3 months) utilizing Meta-Essentials Microsoft Excel (Microsoft Corp., Redmond, WA) workbook. Bias was evaluated via Egger regression and Begg and Mazumdar rank correlation tests. Twelve articles met inclusion and exclusion guidelines, seven for acute dyspareunia and eight for chronic dyspareunia. All publications were randomized controlled trials and were inclusive of a total of 4,081 patients. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using a random effect model. Analysis revealed no statistically significant difference between continuous and interrupted suture groups for acute dyspareunia (RR: 0.98; 95% CI: 0.89-1.08) or chronic dyspareunia (RR: 0.96; 95% CI: 0.83-1.12). Egger regression test (p-value=0.534) and Begg and Mazumdar rank correlation test (p-value=0.570) indicated minimal publication bias. Compiled data does not indicate a preferential suture technique for the reduction of postpartum dyspareunia. These findings are congruent with the ACOG guidelines; therefore, there is no supporting evidence for ACOG's recommendation of continuous suturing to be overturned.

Patient-reported outcomes and outcome measures in childbirth perineal trauma research: a systematic review

INTRODUCTION AND HYPOTHESIS

In evaluating the effectiveness of interventions in perineal trauma research, outcomes reported by patients should have a prominent focus. There is no international consensus regarding the use of either patient-reported outcomes (PROs) or tools used to determine these outcomes (patient-reported outcome measures, PROMs). The objective was to evaluate the selection, reporting and geographical variations of PROs and PROMs in randomised controlled trials (RCTs) on perineal trauma.

METHODS

We performed a systematic review of RCTs in perineal trauma research evaluating outcome and outcome measure reporting. We identified PROs and PROMs and grouped PROs into domains and themes, a classification system based on a medical outcome taxonomy.

RESULTS

Of 48 included RCTs, 47 reported PROs. In total, we identified 51 PROs. Outcome reporting consistency was low, with 27 PROs reported only once. Nine PROs were reported more than five times, the most frequent being perineal pain, with no geographical variation in reporting. Four themes encompassing 12 domains were identified. The most frequently reported theme was "Clinical", with 25 PROs grouped within four domains. "Resource use" and "Adverse events" themes were rarely reported, with only five PROs. PROMs also exhibited variation. Most common were visual analogue scale (VAS; 100 mm), Cleveland Clinic Continence Score, The Faecal Incontinence Quality of Life scale, VAS (0-10) and the McGill Pain Questionnaire.

CONCLUSIONS

Significant heterogeneity in PROs and PROMs was observed among RCTs. Despite inconsistency, PROs are the most prevalent outcome in perineal trauma research. Patient-reported adverse events are underreported. Their use in determining the effectiveness and safety of interventions makes their integration important in perineal trauma core outcome sets. Identification and grouping of outcomes will assist future core outcome consensus studies.

Language barrier as a risk factor for obstetric anal sphincter injury - A case-control study

INTRODUCTION

The incidence of grade 3-4 perineal tears, also known as obstetric anal sphincter injury (OASI), is reported to be between 0.5 and 2.5%. Beyond the medico-economic burden, the consequences of OASI on a woman's emotional, psychological, sexual, and physical wellbeing are considerable. Among the various risk factors of OASI, few data are available about the impact of a language barrier on its incidence.

MATERIAL AND METHODS

We conducted a case-control study to evaluate the effect of language barriers on the risk of OASI comparing 171 women with OASI and 163 matched controls. The matched criteria included ethnicity, age, previous vaginal delivery, delivery mode, prophylactic episiotomy and birthweight. Patients' characteristics were compared and crude ORs and 95% CIs estimated using unadjusted logistic models. Multivariate analysis was performed with recognized potential confounders.

RESULTS

All of the cases had grade 3 tears. Language barrier was a determinant factor of OASI with an OR of 3.32 [1.36-8.90], p = 0.01. Other risk factors were occipito-posterior delivery, African origin and prolonged labor duration (OR 6.33, 95% CI: 2.04-27.78, p = 0.004, OR 1.85, 95% CI: 1.08-3.19, p = 0.03 and OR 1.03, 95% CI: 1.01-1.05, p = 0.004, respectively).

CONCLUSION

Our data suggest that language barrier is an independent risk factor of OASI. Physicians and midwives should attempt to identify patients with a language barrier during prenatal visits. Education about simple terms used during delivery could decrease the incidence of this complication.

Dispareunia en mujeres después de parto vaginal. Prevalencia en dos clínicas de Armenia, Colombia, 2012-2017

Se realizó un estudio de corte transversal que tuvo como objetivo determinar la prevalencia de la dispareunia en mujeres con parto vaginal, evaluar posibles factores de riesgo y la asociación con la episiotomía. Ingresaron mujeres atendidas por parto vaginal entre 2012 y 2017 en dos clínicas de alta complejidad en Armenia (Colombia). Se utilizó el cuestionario Índice de Función Sexual Femenina (IFFS-6) para evaluar la función sexual. Los resultados reportan una prevalencia de dispareunia del 59,37%, siendo más prevalente en mujeres sometidas a episiotomía (OR: 68,17; IC95 %: 60,57-79,15). Respecto a la asociación de la episiotomía con la presencia de dispareunia se encontró asociación significativa con la episiotomía medio-lateral (OR: 8,17; IC95%: 2,15-56,32), lesión del esfínter (OR: 7,32; IC95%: 4,86-12,75) y dehiscencia de la sutura (OR: 6,48; IC95%: 4,92-14,28). Se observaron como factores de riesgo: antecedente de endometriosis (OR: 11,6; IC95 %: 9,15-17,52), dolor pélvico crónico (OR: 3,56; IC95%: 2,21–6,32) e ITS (OR: 2,67; IC95%: 1,54–5,14), p=0,003). Se concluye que la prevalencia de dispareunia en mujeres con parto vaginal, atendidas en Armenia, varía en función de la realización de episiotomía, asociándose tanto a las complicaciones de esta como a otros antecedentes.

Perineal trauma management and follow-up: Are we meeting the standard of care?

BACKGROUND

Birth-related third- and fourth-degree perineal trauma is common and associated with short- and long-term complications.

AIM

To conduct a review of clinical audits investigating management of women with perineal trauma.

MATERIALS AND METHODS

We identified all audits undertaken in eight New Zealand public hospitals between 2005 and 2014 that investigated whether women with birth-related third- and fourth-degree perineal trauma were receiving care according to clinical guidelines. We aggregated audit results and calculated the proportion of women receiving the recommended standard of care.

RESULTS

During the review period, 25 audits investigated intra-operative (n = 11), post-operative (n = 14) and outpatient care (n = 18). Baseline audits showed variation in care by site; intra-operative care (range 39-96% for repair conducted under anaesthesia, 60-96% for repair by or under supervision of a senior clinician, and 33-54% for completion of Accident Compensation Corporation forms); post-operative care (range 40-93% for prescribed antibiotics and 33-96% for stool softeners) and outpatient care (45-84% for referral to outpatient clinic and 54-78% for physiotherapy follow-up). Sustained high quality of care and improvements in adherence with recommendations were seen for most of the follow-up audits (eg 90% adherence for prescribed stool softeners over three audits; over 50% increase in prescribed antibiotics over seven years).

CONCLUSIONS

These clinical audits exemplify the need to measure patient care against standards, learn from the findings, implement changes to improve patient experience and reduce life-long sequelae from perineal trauma. This review showed some progress in some care services and highlighted where further changes are needed to close evidence-practice gaps.

Breast cancer during pregnancy: matched study of diagnostic approach, tumor characteristics, and prognostic factors

INTRODUCTION

Breast cancer is one of the most frequently occurring cancers during pregnancy and its incidence is increasing. Many studies have shown poor outcomes, the causes of which remain unclear.

OBJECTIVES

To analyze radiologic characteristics, histology, and prognosis factors of breast cancer during pregnancy.

METHODS

A total of 42 patients with breast cancer diagnosed during pregnancy (BCP) were matched with 84 patients with breast cancer of similar age who were not pregnant. Sensitivity of radiology, tumor characteristics, prognosis factors, disease-free survival, and overall survival were analyzed.

RESULTS

The sensitivity of breast ultrasound was higher than that of mammography for both groups. Ultrasound sensitivity for cancer was 95.7% in patients with BCP versus 98% in the not pregnant group, with non-statistically significant differences. Mammography sensitivity for cancer was 56.5% in patients with BCP versus 61% in the not pregnant group, with non-statistically significant differences. The stage at diagnosis according to the TNM staging system was significantly higher in patients with BCP with stage IV cancer: 16.7% in patients with BCP versus 3.7% in the not pregnant group (p = 0.03). No statistically significant differences were observed in histologic grade, Ki-67 index, or molecular subtype. Disease-free survival and overall survival were significantly lower in patients with BCP (p = 0.002 and p = 0.04). Multivariate analysis showed no difference when adjusting for stage and surrogate molecular subtype.

CONCLUSION

Breast ultrasound shows a high sensitivity to detect breast cancer during pregnancy. BCP is diagnosed at a higher stage than in nonpregnant women. In our series, patients with BCP had poorer outcomes than the not pregnant group. These results were not observed when adjusting for stage.

Maternal outcomes in subsequent delivery after previous obstetric anal sphincter injury (OASI): a multi-centre retrospective cohort study

INTRODUCTION AND HYPOTHESIS

Women with a history of obstetric anal sphincter injury (OASI) are at increased risk of recurrence (rOASI) at subsequent delivery; however, evidence regarding the factors influencing this risk is limited. Furthermore, little is known about what factors influence the decision to alternatively deliver by elective caesarean section (ELLSCS).

METHODS

Retrospective univariate and multivariate logistic regression analysis of prospectively collected data from four NHS electronic maternity databases including primiparous women sustaining OASIS during a singleton, term, cephalic, vaginal delivery between 2004 and 2015, who had a subsequent delivery.

RESULTS

Two thousand two hundred seventy-two women met the criteria; 10.2% delivering vaginally had a repeat OASI and 59.4% had a second-degree tear. Women having an ELLSCS were more likely to be Caucasian, older, have previously had an operative vaginal delivery (OVD) and have a more severe degree of OASI. Positive predictors for rOASI were increased birth weight and maternal age at both index and subsequent deliveries, a more severe degree of initial OASI and Asian ethnicity. The overall mediolateral episiotomy (MLE) rate was 15.6%; 77.2% of those who had an episiotomy sustained no spontaneous perineal trauma. Only 4.4% of women with a rOASI had an MLE, whilst the MLE rate was 16.9% in those without a recurrence (p < 0.001). MLE decreased the risk of rOASI by 80%. Birth weight > 4 kg increased the risk 2.5 fold.

CONCLUSIONS

Women with previous OASIS are at an increased risk of recurrence. A more liberal use of MLE during subsequent vaginal delivery could significantly reduce the risk of recurrence.

Perineal suture practices. Are they up to date with the evidence based medicine data: A local experience into a university maternity?

OBJECTIVES

To investigate the prevalence of perineal suture techniques then to identify the factors influencing suturing technique choices.

METHODS

Prospective, observational, monocentric study over 20 weeks in a university hospital. A personal questionnaire was completed by medical practitioners performing perineal sutures: years of experience, training attendance, suturing techniques usually used for degrees 1 and 2 tears/episiotomies. For each delivery with perineal tear/episiotomy, the professional answered on the type of suture performed and the reasons for choosing this technique. We distinguished discontinuous sutures (several stitches/continuous locking stitch) from continuous sutures (single thread, single continuous locking stitch). We evaluated the prevalence of the techniques used in our center as well as the factors associated with the choice of technique, then we described the characteristics of the professionals who responded to the survey and their suturing habits.

RESULTS

Among the 401 perineal sutures, 45.4% of them were continuous (n = 182), discontinuous sutures were more performed. Discontinuous sutures were more common in 1st and 2nd degree tears. Residents/obstetricians performed significantly more continuous sutures than midwives. Whatever the type of suture technique used (continuous or discontinuous), professionals sutured in the way they felt most suitable to the degree of tearing/episiotomy. Fifty-one percent of midwives are trained in continuous technique, compared with 81% of residents/obstetricians. Midwives required training in 70% of cases and 64% of residents.

CONCLUSIONS

It appears necessary to disseminate continuous suture techniques and to promote their training in order to improve our practices.

Incidence of perineal pain and dyspareunia following spontaneous vaginal birth: a systematic review and meta-analysis

INTRODUCTION AND HYPOTHESIS

Perineal pain and dyspareunia are experienced by women undergoing a vaginal birth that can have short and longer term physical and psychological morbidities. This review aimed to determine the incidence of perineal pain and dyspareunia following spontaneous vaginal birth (SVB) with intact perineum, first and second-degree perineal trauma or episiotomy.

METHODS

Searches of MEDLINE, EMBASE, CINAHL, AMED and MIDIRS (inception - December 2017) were undertaken with selection criteria of any study evaluating the effect of intact perineum, first- or second-degree perineal trauma on perineal pain or dyspareunia in women with SVB.

RESULTS

Eighteen studies (8 RCTs and 10 NRSs) were included. Fourteen and 12 studies were undertaken to assess perineal pain and dyspareunia after SVB, respectively. Meta-analysis of 16 studies (3133 women) demonstrated that women at 2 days postpartum experienced nearly the same incidence of perineal pain whether perineal trauma existed or not. At 4-10 days postpartum there was a significant reduction in the incidence of perineal pain for both presence and absence of any perineal trauma. Episiotomy was associated with the highest rate of perineal pain. The incidence of dyspareunia was high at resumption of sexual intercourse following SVB with an intact perineum. At 12 months, women still experienced dyspareunia whether perineal trauma existed or not.

CONCLUSIONS

Women experience perineal pain and dyspareunia regardless of the presence or absence of perineal trauma after SVB; nonetheless, the reported incidence is higher if perineal trauma occurred.

Do we need a core outcome set for childbirth perineal trauma research? A systematic review of outcome reporting in randomised trials evaluating the management of childbirth trauma

BACKGROUND

Selecting appropriate outcomes to reflect both beneficial and harmful effects is a critical step in designing childbirth trauma trials.

OBJECTIVE

To evaluate the outcomes and outcome measures reported in randomised controlled trials evaluating interventions for childbirth trauma.

SEARCH STRATEGY

Randomised trials were identified by searching bibliographical databases including the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and EMBASE.

SELECTION CRITERIA

Randomised trials evaluating the efficacy and safety of different techniques in the management of perineal lacerations.

DATA COLLECTION AND ANALYSIS

Two researchers independently assessed studies for inclusion, evaluated methodological quality, and extracted the relevant data. Spearman's ρ correlation and multivariate linear regression analysis using the backward stepwise model were used for analysis.

MAIN RESULTS

Forty-eight randomised trials, reporting data from 20 308 women, were included. Seventeen different interventions were evaluated. Included trials reported 77 different outcomes and 50 different outcome measures. Commonly reported outcomes included pain (34 trials; 70%), wound healing (20 trials; 42%), and anorectal dysfunction (16 trials, 33%). In the multivariate analysis, no relationship was demonstrated between the quality of outcome reporting and year of publication (P = 0.31), journal impact factor (P = 0.49), and methodological quality (P = 0.13).

CONCLUSION

Outcome reporting in childbirth trauma research is heterogeneous. Developing, disseminating, and implementing a core outcome set in future childbirth trauma research could help address these issues.

TWEETABLE ABSTRACT

Developing @coreoutcomes for childbirth trauma research could help to reduce #research waste.

The MOVE-trial: Monocryl® vs. Vicryl Rapide™ for skin repair in mediolateral episiotomies: a randomized controlled trial

BACKGROUND

Previous studies have shown that complaints after episiotomy repair depend on the method and material used for repair. The objective of our study was to determine which of two frequently used suture materials, Monocryl® (poliglecaprone 25) and Vicryl Rapide™ (polyglactin 910), is superior for intracutaneous closure of the skin in mediolateral episiotomies.

METHODS

In a randomized controlled trial performed in a teaching hospital in the Netherlands between 2010 and 2013 250 primiparous women with uncomplicated mediolateral episiotomies were randomly allocated to intracutaneous skin closure with either Monocryl® or Vicryl Rapide™. All other layers were sutured with Vicryl 2-0 and Vicryl 0 in both groups. Pain scores and complications were documented using questionnaires during the first three months post partum. The primary outcome was pain 10 days after delivery in sitting position established by Visual Analogous Scale (VAS). Secondary outcomes were pain scores at different time points and reported complications such as infections, dehiscence and dyspareunia one day, 10 days, six weeks and three months after delivery.

RESULTS

Of 250 allocated women 54% returned questionnaires. No statistical difference was found between both groups for the primary outcome (VAS 2,8 (95% CI 2,18-3,44) vs. VAS 2,5 (95% CI 2,00-2,98), p = 0,43). With regard to secondary outcomes only self-reported dehiscence was significantly different, favouring Monocryl® (10% vs. 25%, p = 0.016).

CONCLUSIONS

Use of Monocryl® 3-0 and Vicryl Rapide™ 3-0 for intracutaneous closure of the skin after mediolateral episiotomy leads to equal pain scores ten days after delivery and therefore both materials may be considered for this use. Monocryl® 3-0 might be favourable over Vicryl Rapide™ 3-0 due to less self-reported dehiscence after intracutaneous closure of the skin in mediolateral episiotomies.

TRIAL REGISTRATION

The trial was retrospectively registered under trial nr. ISRCTN29869308 on 20-04-2016.

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

BACKGROUND

Most vaginal births are associated with trauma to the genital tract. The morbidity associated with perineal trauma can be significant, especially when it comes to third- and fourth-degree tears. Different interventions including perineal massage, warm or cold compresses, and perineal management techniques have been used to prevent trauma. This is an update of a Cochrane review that was first published in 2011.

OBJECTIVES

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

SEARCH METHODS

We searched Cochrane Pregnancy and Childbirth's Trials Register (26 September 2016) and reference lists of retrieved studies.

SELECTION CRITERIA

Published and unpublished randomised and quasi-randomised controlled trials evaluating perineal techniques during the second stage of labour. Cross-over trials were not eligible for inclusion.

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed trials for inclusion, extracted data and evaluated methodological quality. We checked data for accuracy.

MAIN RESULTS

Twenty-two trials were eligible for inclusion (with 20 trials involving 15,181 women providing data). Overall, trials were at moderate to high risk of bias; none had adequate blinding, and most were unclear for both allocation concealment and incomplete outcome data. Interventions compared included the use of perineal massage, warm and cold compresses, and other perineal management techniques.Most studies did not report data on our secondary outcomes. We downgraded evidence for risk of bias, inconsistency, and imprecision for all comparisons. Hands off (or poised) compared to hands onHands on or hands off the perineum made no clear difference in incidence of intact perineum (average risk ratio (RR) 1.03, 95% confidence interval (CI) 0.95 to 1.12, two studies, Tau² 0.00, I² 37%, 6547 women; moderate-quality evidence), first-degree perineal tears (average RR 1.32, 95% CI 0.99 to 1.77, two studies, 700 women; low-quality evidence), second-degree tears (average RR 0.77, 95% CI 0.47 to 1.28, two studies, 700 women; low-quality evidence), or third- or fourth-degree tears (average RR 0.68, 95% CI 0.21 to 2.26, five studies, Tau² 0.92, I² 72%, 7317 women; very low-quality evidence). Substantial heterogeneity for third- or fourth-degree tears means these data should be interpreted with caution. Episiotomy was more frequent in the hands-on group (average RR 0.58, 95% CI 0.43 to 0.79, Tau² 0.07, I² 74%, four studies, 7247 women; low-quality evidence), but there was considerable heterogeneity between the four included studies.There were no data for perineal trauma requiring suturing. Warm compresses versus control (hands off or no warm compress)A warm compress did not have any clear effect on the incidence of intact perineum (average RR 1.02, 95% CI 0.85 to 1.21; 1799 women; four studies; moderate-quality evidence), perineal trauma requiring suturing (average RR 1.14, 95% CI 0.79 to 1.66; 76 women; one study; very low-quality evidence), second-degree tears (average RR 0.95, 95% CI 0.58 to 1.56; 274 women; two studies; very low-quality evidence), or episiotomy (average RR 0.86, 95% CI 0.60 to 1.23; 1799 women; four studies; low-quality evidence). It is uncertain whether warm compress increases or reduces the incidence of first-degree tears (average RR 1.19, 95% CI 0.38 to 3.79; 274 women; two studies; I² 88%; very low-quality evidence).Fewer third- or fourth-degree perineal tears were reported in the warm-compress group (average RR 0.46, 95% CI 0.27 to 0.79; 1799 women; four studies; moderate-quality evidence). Massage versus control (hands off or routine care)The incidence of intact perineum was increased in the perineal-massage group (average RR 1.74, 95% CI 1.11 to 2.73, six studies, 2618 women; I² 83% low-quality evidence) but there was substantial heterogeneity between studies). This group experienced fewer third- or fourth-degree tears (average RR 0.49, 95% CI 0.25 to 0.94, five studies, 2477 women; moderate-quality evidence).There were no clear differences between groups for perineal trauma requiring suturing (average RR 1.10, 95% CI 0.75 to 1.61, one study, 76 women; very low-quality evidence), first-degree tears (average RR 1.55, 95% CI 0.79 to 3.05, five studies, Tau² 0.47, I² 85%, 537 women; very low-quality evidence), or second-degree tears (average RR 1.08, 95% CI 0.55 to 2.12, five studies, Tau² 0.32, I² 62%, 537 women; very low-quality evidence). Perineal massage may reduce episiotomy although there was considerable uncertainty around the effect estimate (average RR 0.55, 95% CI 0.29 to 1.03, seven studies, Tau² 0.43, I² 92%, 2684 women; very low-quality evidence). Heterogeneity was high for first-degree tear, second-degree tear and for episiotomy - these data should be interpreted with caution. Ritgen's manoeuvre versus standard careOne study (66 women) found that women receiving Ritgen's manoeuvre were less likely to have a first-degree tear (RR 0.32, 95% CI 0.14 to 0.69; very low-quality evidence), more likely to have a second-degree tear (RR 3.25, 95% CI 1.73 to 6.09; very low-quality evidence), and neither more nor less likely to have an intact perineum (RR 0.17, 95% CI 0.02 to 1.31; very low-quality evidence). One larger study reported that Ritgen's manoeuvre did not have an effect on incidence of third- or fourth-degree tears (RR 1.24, 95% CI 0.78 to 1.96,1423 women; low-quality evidence). Episiotomy was not clearly different between groups (RR 0.81, 95% CI 0.63 to 1.03, two studies, 1489 women; low-quality evidence). Other comparisonsThe delivery of posterior versus anterior shoulder first, use of a perineal protection device, different oils/wax, and cold compresses did not show any effects on perineal outcomes. Only one study contributed to each of these comparisons, so data were insufficient to draw conclusions.

AUTHORS' CONCLUSIONS

Moderate-quality evidence suggests that warm compresses, and massage, may reduce third- and fourth-degree tears but the impact of these techniques on other outcomes was unclear or inconsistent. Poor-quality evidence suggests hands-off techniques may reduce episiotomy, but this technique had no clear impact on other outcomes. There were insufficient data to show whether other perineal techniques result in improved outcomes.Further research could be performed evaluating perineal techniques, warm compresses and massage, and how different types of oil used during massage affect women and their babies. It is important for any future research to collect information on women's views.

Perineal resuturing versus expectant management following vaginal delivery complicated by a dehisced wound (PREVIEW): a pilot and feasibility randomised controlled trial

OBJECTIVE

To establish the feasibility of conducting a definitive randomised controlled trial (RCT) comparing the effectiveness of resuturing versus expectant management for dehisced perineal wounds.

DESIGN

A multicentre pilot and feasibility RCT.

SETTING

Ten UK maternity units from July 2011 to July 2013.

POPULATION

Eligible women with a dehisced perineal wound within 2 weeks of childbirth.

METHODS

The interventions were resuturing or expectancy. Randomisation was via web or telephone, stratified by participating centre. Blinding was not possible due to the nature of the interventions. Analysis was by intention-to-treat.

OUTCOME

The primary outcome measure was wound healing at 6-8 weeks.

RESULTS

The study revealed a number of feasibility issues, particularly strong patient and clinician preference for treatment options at recruiting centres and the timing of the primary outcome measure. Thirty-four women were randomised (17 in each arm). Data from 33 women were analysed on an intention-to-treat analysis to obtain preliminary estimates of effect size. There was a difference in wound healing at 2 weeks favouring resuturing (OR 20.00, 95% CI 2.04 to 196.37, p=0.004). However, by 6-8 weeks all but one wound in both groups had healed.

CONCLUSIONS

PREVIEW revealed a number of feasibility issues, which impacted on recruitment rate. These will have to be taken into account in the design of any future definitive study. In this feasibility study, resuturing was associated with quicker wound healing and women reported higher satisfaction rates with the outcome at 3 months.

Single-knot versus multiple-knot technique of perineal repair: a randomised controlled trial

PURPOSE

An important factor influencing the outcome of perineal repair is the repair technique. This study was done to determine if there is a difference in post perineal repair pain scores following the use of the standard multiple-knot technique (MKT) of perineal repair and a single-knot technique (SKT).

METHODS

We randomised 260 women who sustained a second-degree perineal tear at the University of Benin Teaching Hospital, Benin City, Nigeria and had perineal repair using either a SKT or a MKT between 1 July 2014 and 28 February 2015. Primary outcome measure was pain assessed with a numerical rating scale (0 = no pain, 10 = worst imaginable pain) on day two, day 10 and at 3 months. Secondary outcome measures were pain scores during basic activities of daily living, analgesia use, dyspareunia and patient satisfaction.

RESULTS

Mean pain scores were significantly lower in the SKT group on day two (2.8 versus 5.6; P < 0.001) and day 10 (1.8 versus 3.3; P < 0.001). Significantly fewer women in the SKT group reported pain on day two (90/126, 71.4 % versus 122/128, 95.3 %; Relative Risk [RR] 0.6, 95 % Confidence Interval [CI] 0.6-0.8; P < 0.001), and day 10 (69/126, 54.8 % versus 107/128, 83.6 %; RR 0.7, 95 % CI 0.5-0.7; P < 0.001)]. Women in the SKT group were more likely to be satisfied with outcome of repair at three months (RR 1.4, 95 % CI 1.2-1.5; P < 0.001). No difference in pain scores and dyspareunia at 3 months.

CONCLUSIONS

SKT of perineal repair is associated with significantly less pain in the first 10 days postdelivery and a higher patient satisfaction rate at 3 months.

Mediolateral versus lateral episiotomy and their effect on postpartum coital activity and dyspareunia rate 3 and 6 months postpartum

OBJECTIVES

Comparison of the effects of two episiotomy types on sexual activity, dyspareunia and overall satisfaction after childbirth.

STUDY DESIGN

A prospective follow-up study of a randomized comparative trial evaluating peripartum outcome of a vaginal delivery after mediolateral (MLE) or lateral (LE) episiotomy.

MAIN OUTCOME MEASURES

The participants completed questionnaires regarding sexual activity, dyspareunia, perineal pain, aesthetic appearance and overall satisfaction 3 (3M) and 6 months (6M) postpartum.

RESULTS

A total of 648 women were available for the analyses (306 MLE, 342 LE). The groups showed no difference regarding resumption and regularity of sex, timing of resumption, frequency and intensity of dyspareunia, perineal pain, aesthetic appearance or overall satisfaction 3M or 6M postpartum. 98.0% of women after MLE and 97.7% after LE resumed sexual intercourse within 6M after delivery (p = 0.74). In the same period 15.6% of women after MLE and 16.1% after LE suffered from considerable dyspareunia (p = 0.86).

CONCLUSIONS

Quality of sexual life and perception of perineal pain after MLE is equivalent to LE.

Perineal Body and Genital Hiatus in the Third Trimester and Risk of Perineal Laceration

OBJECTIVE

We aimed to determine whether pelvic organ prolapse quantification measurements of genital hiatus (gh) or perineal body (pb) obtained in the late third trimester are predictors of obstetric perineal laceration in nulliparous women.

METHODS

Nulliparous women with singleton gestation were prospectively recruited after 35-week gestation, and gh and pb measurements were obtained. After delivery, determination of the presence and degree of perineal laceration were recorded. Correlation of gh and pb measurements with risk of perineal laceration (defined as second, third, or fourth degree) was assessed using the Wilcoxon rank sum test.

RESULTS

We recruited 224 patients and 133 met inclusion criteria after delivery. The mean (SD) age was 27.2 (4.0) years and mean (SD) prepregnancy body mass index was 24.1 (4.6) kg/m. Seventy patients (52.6%) had either a second-degree (n = 64) or third-degree (n = 6) laceration. No fourth-degree lacerations were recorded. We found no significant difference in the median gh (3.5 vs 3.0 cm, P = 0.34) and pb (3.5 vs 3.5 cm, P = 0.54) measurements among women with and without perineal lacerations.

CONCLUSIONS

Our data suggest that antenatal measurement of gh and pb does not correlate with the risk of obstetric perineal laceration in nulliparous patients undergoing spontaneous vaginal delivery.

[Impact of pelvic floor muscle training on prevention of perineal pain and dyspareunia in postpartum]

OBJECTIVE

Assessing the impact of perineal rehabilitation and massage on perineal pain and dyspareunia in the postpartum period, between 15days and 12months after delivery.

METHODS

We conducted an exhaustive review of the literature concerning pelvic floor rehabilitation in the postpartum between 1987 and May 2015, grading data by levels of evidence (LOE) according to the methodology recommendations for clinical guidelines.

RESULTS

Pelvic floor rehabilitation in the postpartum is not associated with a decreased prevalence of perineal pain and dyspareunia at 1year (LOE3). The practice of digital perineal massage during the third trimester of pregnancy is not associated with decreased prevalence at 3-month postpartum of perineal pain or dyspareunia (RR=0.64; 95% CI [0.39-1.08] and RR=0.96; 95% CI [0.84-1.08], respectively), except for women who have delivered vaginally (RR=0.45; 95% CI [0,24-0.87]) (LOE2). The practice of digital perineal massage or application of warm packs in the second stage of labor does not reduce perineal pain (RR=0.93; 95% CI [0.66-1.32]) or dyspareunia (RR=0.99; 95% CI [0.74-1.34]) at 3-month postpartum (LOE2).

CONCLUSION

There is no evidence of long-term benefit of perineal rehabilitation and perineal massage on perineal pain and dyspareunia in the year following childbirth. Further studies are needed to accurately assess the impact of therapeutic strategies proposed in France.

Continuous versus interrupted sutures for facial surgery repair: a randomized prospective study

BACKGROUND

The cosmetic appearance of a facial scar is a concern for patients undergoing Mohs micrographic surgery (MMS). Although suturing technique may influence scar cosmesis, few studies have been published comparing suturing methods for MMS repair.

OBJECTIVE

To compare the cosmetic appearance of facial MMS scars sutured with either continuous or interrupted percutaneous nylon sutures.

MATERIALS AND METHODS

Patients with facial MMS defects were randomized to have half their scar sutured with interrupted 5-0 nylon stitches, whereas the other half of the scar was closed with running 5-0 nylon stitches. The appearance of each half of the scar was assessed at 1 week, 8 weeks, and 6 months by the principal investigator. Blinded photographic evaluation at 1 week and 6 months was completed by a plastic surgeon and general dermatologist.

RESULTS

A total of 105 patients were entered into the trial, and 101 completed all time point assessments. There was no statistically significant difference in scar outcome using each of the 3 scar assessment scales, at any time point, for any assessor (blinded and nonblinded).

CONCLUSION

Interrupted and continuous 5-0 nylon sutures result in an equivalent final cosmetic appearance of facial MMS scars. Given its advantages, running sutures may be the preferred closure technique for facial repair.

The knowledge, practice and opinion of midwives' in the UK on their training in obstetric perineal repair

PURPOSE

To investigate the knowledge and practice of perineal repair by midwives' in the UK, as well as their perception of the adequacy of their training.

METHODS

An anonymous structured questionnaire survey was conducted. Standard statistical comparative analysis was performed between groups. Significant differences were quantified by calculating odds ratios and 95% confidence intervals. P < 0.05 was considered significant.

RESULTS

Analysis of 592 responses revealed that midwives who believed that they had adequate training were ten times more likely to report that they have an adequate knowledge of pelvic floor anatomy (OR 9.8, 95% CI 6.4-14.9, P < 0.001), six times more likely to be aware of recommended techniques of perineal repair (OR 6.1, 95% CI 3.8-9.7, P < 0.001) and 16 times more likely to feel competent to perform a repair (OR 16.1, 95% CI 9.3-27.2, P < 0.001). Midwives who had formal hands-on perineal repair training were four times more likely to report that they have an adequate knowledge of pelvic floor anatomy (OR 4.1, 95% CI 2.8-5.8, P < 0.001) and four times more likely to feel competent enough to perform a repair (OR 3.6 95% CI 2.4-4.9, P < 0.001).

CONCLUSION

The majority of midwives in the study sample report that they were unable to identify key perineal anatomy and believed that their pre-qualification training on perineal repair was inadequate. They also believed that midwives should routinely repair simple second-degree perineal tears.

Evaluation of in vivo properties of Velosorb™ fast versus Vicryl™ rapide in a functional rabbit model of intradermic suture and episiotomy

OBJECTIVE

Fast-absorbing polyglactin 910 is commonly used to suture skin and vaginal incisions. In vitro studies have shown similar tensile strength properties between Velosorb™ Fast and Vicryl™ Rapide (Al-Qattan MM. J Hand Surg Br Eur. 2005;30(1):90-91). This randomized study compared Velosorb™ Fast (Covidien) with Vicryl™ Rapide (Ethicon) in a rabbit model of intradermic suture and episiotomy.

MATERIALS AND METHODS

This randomized prospective study was performed on 20 New Zealand rabbits, in which we realized a mediolateral perineo-vaginal incision and two vertical skin incisions of about 8 cm on the abdominal wall. The sutures were randomized between Velosorb™ Fast (Covidien) and Vicryl™ Rapide (Ethicon), and each rabbit was treated with the same suture on both vaginal incision and left abdominal incision, while the right abdominal incision was closed with an alternate suture. A macroscopic examination was performed on days 5 and 11. On day 11, animals were sacrificed for histological (Badylak quantitative score) and electron microscopic examinations. Differences were considered significant at p < .05.

RESULTS

All of the rabbits survived and were included in the final results. Fifty-one sutures were visible by histologic analysis (27 in the Velosorb™ Fast group and 24 in the Vicryl™ Rapide group). The power of the study was ≥80%. There was no significant difference between the two groups based on the total histologic Badylak score analysis or the Badylak sub-score analysis.

CONCLUSIONS

Velosorb™ Fast seems to be as efficient as Vicryl™ Rapide for use in perineal and skin closure.

Clinical evaluation of early postpartum pain and healing outcomes after mediolateral versus lateral episiotomy

OBJECTIVE

To evaluate short-term perineal pain among primiparous women after mediolateral episiotomy (MLE) and lateral episiotomy (LE).

METHODS

The prospective randomized study was conducted in the Czech Republic during 2010-2012. Consecutive primiparous women who gave birth at or after 37 weeks of pregnancy and had indications for an episiotomy were enrolled and randomly assigned to undergo MLE or LE. Patients were unaware of the episiotomy type performed. The primary outcomes were pain at 24 hours, 72 hours, and 10 days post partum, measured by a visual analog scale, verbal rating scale, interference with activities of daily living, and amount of analgesic use.

RESULTS

The analysis included 266 women who underwent MLE and 297 women who underwent LE. Complete relief of pain was observed in 6 (2.3%) of 266 women after 24 hours, 21 (8.0%) of 264 after 72 hours, and 77 (29.1%) of 265 after 10 days in the MLE group, and in 11 (3.9%) of 285, 23 (7.7%) of 297, and 78 (26.4%) of 295 in the LE group, respectively (P=0.36). There were no significant differences in overall pain scores from any rating system or in the amount of analgesics used.

CONCLUSION

Incidence and extent of pain in the first 10 days after LE correspond to those after adequately performed MLE.

Episiotomy and obstetric perineal wound dehiscence: beyond soreness

Postpartum episiotomy dehiscence is a rare complication of vaginal delivery. Infection rates in episiotomy wounds are surprisingly low; however, it remains the most common cause of wound dehiscence, which may lead to major physical, psychological and social problems if left untreated. Most dehisced perineal wounds are left to heal naturally by secondary intention. This approach often results in a protracted period of significant morbidity for women. There is emerging evidence that early re-suturing closure of broken-down perineal wounds may have a better outcome, but randomised controlled trials are needed to yield evidence-based guidance for this management approach.

Secondary suturing compared to non-suturing for broken down perineal wounds following childbirth

BACKGROUND

Each year approximately 350,000 women in the United Kingdom and millions more worldwide, experience perineal suturing following childbirth. The postpartum management of perineal trauma is a core component of routine maternity care. However, for those women whose perineal wound dehisces (breaks down), the management varies depending on individual practitioners preferences as there is limited scientific evidence and no clear guidelines to inform best practice. For most women the wound will be managed expectantly whereas, others may be offered secondary suturing.

OBJECTIVES

To evaluate the therapeutic effectiveness of secondary suturing of dehisced perineal wounds compared to non-suturing (healing by secondary intention, expectancy).

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 July 2013) and reference lists of retrieved studies.

SELECTION CRITERIA

Randomised controlled trials of secondary suturing of dehisced perineal wounds (second-, third- or fourth-degree tear or episiotomy), following wound debridement and the removal of any remaining suture material within the first six weeks following childbirth compared with non-suturing.

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed trials for inclusion. Two review authors independently assessed trial quality and extracted data. Data were checked for accuracy.

MAIN RESULTS

Two small studies of poor methodological quality including 52 women with a dehisced and/or infected episiotomy wound at point of entry have been included.Only one small study presented data in relation to wound healing at less than four weeks, (the primary outcome measure for this review), although no reference was made to demonstrate how healing was measured. There was a trend to favour this outcome in the resuturing group, however, this difference was not statistically significant (risk ratio (RR) 1.69, 95% confidence interval (CI) 0.73 to 3.88, one study, 17 women).Similarly, only one trial reported on rates of dyspareunia (a secondary outcome measure for this review) at two months and six months with no statistically significant difference between both groups; two months, (RR 0.44, 95% CI 0.18 to 1.11, one study, 26 women) and six months, (RR 0.39, 95% CI 0.04 to 3.87, one study 32 women). This trial also included data on the numbers of women who resumed sexual intercourse by two months and six months. Significantly more women in the secondary suturing group had resumed intercourse by two months (RR 1.78, 95% CI 1.10 to 2.89, one study, 35 women), although by six months there was no significant difference between the two groups (RR 1.08, 95% CI, 0.91 to 1.28).Neither of the trials included data in relation to the following prespecified secondary outcome measures: pain at any time interval; the woman's satisfaction with the aesthetic results of the perineal wound; exclusive breastfeeding; maternal anxiety or depression.

AUTHORS' CONCLUSIONS

Based on this review, there is currently insufficient evidence available to either support or refute secondary suturing for the management of broken down perineal wounds following childbirth. There is an urgent need for a robust randomised controlled trial to evaluate fully the comparative effects of both treatment options.

Perineal Assessment and Repair Longitudinal Study (PEARLS): a matched-pair cluster randomized trial

BACKGROUND

Perineal trauma during childbirth affects millions of women worldwide every year. The aim of the Perineal Assessment and Repair Longitudinal Study (PEARLS) was to improve maternal clinical outcomes following childbirth through an enhanced cascaded multiprofessional training program to support implementation of evidence-based perineal management.

METHODS

This was a pragmatic matched-pair cluster randomized controlled trial (RCT) that enrolled women (n = 3681) sustaining a second-degree perineal tear in one of 22 UK maternity units (clusters), organized in 11 matched pairs. Units in each matched pair were randomized to receive the training intervention either early (group A) or late (group B). Outcomes within each cluster were assessed prior to any training intervention (phase 1), and then after the training intervention was given to group A (phase 2) and group B (phase 3). Focusing on phase 2, the primary outcome was the percentage of women who had pain on sitting or walking at 10 to 12 days post-natal. Secondary outcomes included use of pain relief at 10 to 12 days post-natal, need for suture removal, uptake and duration of exclusive breastfeeding, and perineal wound infection. Practice-based measures included implementation of evidence into practice to promote effective clinical management of perineal trauma. Cluster-level paired t-tests were used to compare groups A and B.

RESULTS

There was no significant difference between the clusters in phase 2 of the study in the average percentage of women reporting perineal pain on sitting and walking at 10 to 12 days (mean difference 0.7%; 95% CI -10.1% to 11.4%; P = 0.89). The intervention significantly improved overall use of evidence-based practice in the clinical management of perineal trauma. Following the training intervention, group A clusters had a significant reduction in mean percentages of women reporting perineal wound infections and of women needing sutures removed.

CONCLUSION

PEARLS is the first RCT to assess the effects of a 'training package on implementation of evidence-based perineal trauma management. The intervention did not significantly improve the primary outcome but did significantly improve evidence-based practice and some of the relevant secondary clinical outcomes for women.

Continuous and interrupted suturing techniques for repair of episiotomy or second-degree tears

BACKGROUND

Millions of women worldwide undergo perineal suturing after childbirth and the type of repair may have an impact on pain and healing. For more than 70 years, researchers have been suggesting that continuous non-locking suture techniques for repair of the vagina, perineal muscles and skin are associated with less perineal pain than traditional interrupted methods.

OBJECTIVES

To assess the effects of continuous versus interrupted absorbable sutures for repair of episiotomy and second-degree perineal tears following childbirth.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (20 January 2012).

SELECTION CRITERIA

Randomised trials examining continuous and interrupted suturing techniques for repair of episiotomy and second-degree tears after vaginal delivery.

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed trial quality. Two of the three authors independently extracted data and a third review author checked them. We contacted study authors for additional information.

MAIN RESULTS

Sixteen studies, involving 8184 women at point of entry, from eight countries, were included. The trials were heterogeneous in respect of operator skill and training. Meta-analysis showed that continuous suture techniques compared with interrupted sutures for perineal closure (all layers or perineal skin only) are associated with less pain for up to 10 days' postpartum (risk ratio (RR) 0.76; 95% confidence interval (CI) 0.66 to 0.88, nine trials). There was an overall reduction in analgesia use associated with the continuous subcutaneous technique versus interrupted stitches for repair of perineal skin (RR 0.70; 95% CI 0.59 to 0.84). There was also a reduction in suture removal in the continuous suturing groups versus interrupted (RR 0.56; 95% CI 0.32 to 0.98), but no significant differences were seen in the need for re-suturing of wounds or long-term pain.

AUTHORS' CONCLUSIONS

The continuous suturing techniques for perineal closure, compared with interrupted methods, are associated with less short-term pain, need for analgesia and suture removal. Furthermore, there is also some evidence that the continuous techniques used less suture material as compared with the interrupted methods (one packet compared to two or three packets, respectively).

How good are we at implementing evidence to support the management of birth related perineal trauma? A UK wide survey of midwifery practice

BACKGROUND

The accurate assessment and appropriate repair of birth related perineal trauma require high levels of skill and competency, with evidence based guideline recommendations available to inform UK midwifery practice. Implementation of guideline recommendations could reduce maternal morbidity associated with perineal trauma, which is commonly reported and persistent, with potential to deter women from a future vaginal birth. Despite evidence, limited attention is paid to this important aspect of midwifery practice. We wished to identify how midwives in the UK assessed and repaired perineal trauma and the extent to which practice reflected evidence based guidance. Findings would be used to inform the content of a large intervention study.

METHODS

A descriptive cross sectional study was completed. One thousand randomly selected midwives were accessed via the Royal College of Midwives (RCM) and sent a questionnaire. Study inclusion criteria included that the midwives were in clinical practice and undertook perineal assessment and management within their current role. Quantitative and qualitative data were collated. Associations between midwife characteristics and implementation of evidence based recommendations for perineal assessment and management were examined using chi-square tests of association.

RESULTS

405 midwives (40.5%) returned a questionnaire, 338 (83.5%) of whom met inclusion criteria. The majority worked in a consultant led unit (235, 69.5%) and over a third had been qualified for 20 years or longer (129, 38.2%). Compliance with evidence was poor. Few (6%) midwives used evidence based suturing methods to repair all layers of perineal trauma and only 58 (17.3%) performed rectal examination as part of routine perineal trauma assessment. Over half (192, 58.0%) did not suture all second degree tears. Feeling confident to assess perineal trauma all of the time was only reported by 116 (34.3%) midwives, with even fewer (73, 21.6%) feeling confident to perform perineal repair all of the time. Two thirds of midwives (63.5%) felt confident to perform an episiotomy. Midwives qualified for 20 years or longer and those on more senior clinical grades were most likely to implement evidence based recommendations and feel confident about perineal management.

CONCLUSIONS

There are considerable gaps with implementation of evidence to support management of perineal trauma.

Perineal resuturing versus expectant management following vaginal delivery complicated by a dehisced wound (PREVIEW): protocol for a pilot and feasibility randomised controlled trial

BACKGROUND

Each year, approximately 350 000 women in the UK experience perineal suturing following childbirth. For those women whose perineal wound dehisces, the management will vary according to individual practitioner's preferences. For most women, the wound will be managed expectantly (healing by secondary intention), whereas others may be offered resuturing. However, there is limited scientific evidence and no clear guidelines to inform best practice. PREVIEW is a two-part study aiming to identify the best management strategy for dehisced perineal wounds, in terms of clinical effectiveness and women's preferences.

METHODS/DESIGN

The main part of this study is a pilot and feasibility randomised controlled trial designed to provide preliminary evidence of the effectiveness of resuturing versus expectant management for dehisced perineal wounds following childbirth and to feed into the design and feasibility of a larger definitive trial. 144 participants will be randomly allocated to either intervention. The primary outcome is the proportion of women with a healed perineal wound at 6-8 weeks from the trial entry. Secondary outcomes include perineal pain, breast feeding rates, dyspareunia and women's satisfaction with the aesthetic results of the wound healing at 6 weeks, 3 months and 6 months post randomisation. Information will be collected using validated questionnaires. The second part of this study will be to conduct semistructured interviews with 12 study participants, aiming to capture information relating to their physical and psychological experiences following perineal wound dehiscence, assess the acceptability of the research plan and ensure that all outcomes relevant to women are included in the definitive trial.

DISSEMINATION

The results of this study will inform a definitive randomised controlled trial that will provide conclusive evidence of what is the best management of perineal wound dehiscence. This will potentially lead to significant improvements in perineal care and will help to reduce the short- and long-term morbidity experienced by women.

CLINICAL TRIALS REGISTRATION

PREVIEW is registered with the International Standard Research for Clinical Trials (no: ISRCTN05754020) and adopted as a National Institute for Health Research (NIHR) Reproductive Health and Childbirth specialty group portfolio study UKCRN ID 9098.

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

BACKGROUND

Most vaginal births are associated with some form of trauma to the genital tract. The morbidity associated with perineal trauma is significant, especially when it comes to third- and fourth-degree tears. Different perineal techniques and interventions are being used to prevent perineal trauma. These interventions include perineal massage, warm compresses and perineal management techniques.

OBJECTIVES

The objective of this review was to assess the effect of perineal techniques during the second stage of labour on the incidence of perineal trauma.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (20 May 2011), the Cochrane Central Register of ControlledTrials (The Cochrane Library 2011, Issue 2 of 4), MEDLINE (January 1966 to 20 May 2011) and CINAHL (January 1983 to 20 May 2011).

SELECTION CRITERIA

Published and unpublished randomised and quasi-randomised controlled trials evaluating any described perineal techniques during the second stage.

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed trails for inclusion, extracted data and evaluated methodological quality. Data were checked for accuracy.

MAIN RESULTS

We included eight trials involving 11,651 randomised women. There was a significant effect of warm compresses on reduction of third- and fourth-degree tears (risk ratio (RR) 0.48, 95% confidence interval (CI) 0.28 to 0.84 (two studies, 1525 women)). There was also a significant effect towards favouring massage versus hands off to reduce third- and fourth-degree tears (RR 0.52, 95% CI 0.29 to 0.94 (two studies, 2147 women)). Hands off (or poised) versus hand on showed no effect on third- and fourth-degree tears, but we observed a significant effect of hands off on reduced rate of episiotomy (RR 0.69, 95% CI 0.50 to 0.96 (two studies, 6547 women)).

AUTHORS' CONCLUSIONS

The use of warm compresses on the perineum is associated with a decreased occurrence of perineal trauma. The procedure has shown to be acceptable to women and midwives. This procedure may therefore be offered to women.

Effectiveness of an educational programme in perineal repair for midwives

OBJECTIVE

to evaluate the effectiveness of a work-based module and in-service educational programme in perineal repair for midwives on their perceived level of competency undertaking this skill in clinical practice.

DESIGN

a quasi-experimental pre-post intervention case study combining a non-equivalent comparison group and evaluation action research.

SETTING

six NHS consultant/midwifery led Trusts in South East England between December 2002 and 2006.

PARTICIPANTS

145 midwives from six NHS Trusts.

INTERVENTIONS

a post-registration work-based module in perineal repair for midwives and alternative two hour in-service perineal repair workshops across five intervention Trusts.

MAIN OUTCOME MEASURES

midwives' perceived level of competency and confidence undertaking perineal repair.

MAIN FINDINGS

significantly greater numbers of midwives were able to practice perineal repair at higher levels of competency following an educational intervention in five intervention Trusts (P<.006). There was a non-significant difference in the comparison Trust (P<.535). In addition, an educational programme for midwives increased the numbers of senior student midwives who were able to participate in perineal repair confidently under the direct supervision of their mentor when they perceived that their mentor was confident and competent undertaking the procedure.

KEY CONCLUSIONS

an educational programme in perineal repair can make a significant difference to the midwives' perceived level of competency and confidence when assessing and managing perineal trauma and repair.

IMPLICATIONS FOR PRACTICE

competency and expertise are complex phenomena and the data has provided greater insight into the complex nature of workplace learning alongside the multiple factors influencing clinical decision-making such as staff shortage, time constraints and inadequate numbers of midwives who are able to instruct, supervise and assess competency in perineal repair. Funding for training is fundamental for the sustainability of future practice development.

Evaluation of the incision angle of mediolateral episiotomy at 60 degrees

OBJECTIVE

To study the angle of mediolateral episiotomy at the time of cut, after primary repair, and 6 months postpartum; and the incidence and severity of perineal pain and anal incontinence 6 months after delivery.

METHODS

The study group comprised 60 consecutively recruited primiparous women who required episiotomy during delivery assisted by 2 obstetricians. The incision angle of episiotomy (defined as 60°) was measured before cutting, after primary repair, and after 6 months. At follow-up, perineal pain was evaluated by a verbal rating score; anal incontinence was assessed by St Mark's score.

RESULTS

The angles differed significantly among the incision (60°), repair (45°), and 6-month (48°) measurements (P < 0.001). There was a poor correlation between the suture angle and the angle measured at 6 months postpartum. No severe perineal tear was diagnosed in the cohort. At 6 months postpartum, only 1 woman reported mild symptoms of de novo anal incontinence, whereas 7 women reported perineal pain related to episiotomy.

CONCLUSION

An incision angle of mediolateral episiotomy of 60° resulted in a low incidence of anal sphincter tearing, anal incontinence and perineal pain. A randomized controlled trial is needed to assess the outcome when different angles of episiotomy are used.

Continuous versus interrupted episiotomy repair with monofilament or multifilament absorbed suture materials: a randomised controlled trial

PURPOSE

To compare different repair techniques and different suture materials for episiotomy.

METHODS

160 women having vertex delivery with right-mediolateral episiotomy were randomly allocated to four groups. In the groups where continuos technique was performed, vaginal mucosa, perineal muscles and the skin were sutured continuously. In the groups of interrupted technique, vaginal mucosa was sutured with continuous sutures, then muscle layers and skin were closed by interrupted sutures. Two different types of synthetic absorbed suture material were used: monofilament type is in form of polyglycolide-co-caprolactone and multifilament one is polyglactin 910-Rapide. Perineal pain during different activities on the first and tenth day postpartum and also during sexual intercourse 6 weeks after the delivery was questioned by visual analogous scale (VAS). Furthermore, repair time, amount of suture and episiotomy complications were investigated in each groups.

RESULTS

On the first day after delivery, the perineal pain scores, the repair time, the amount of suture were statistically less in the continuous technique groups. The differences between the pain at tenth day and during sexual intercourse 6 weeks after the delivery were statistically same.

CONCLUSIONS

The continuous suturing techniques for episiotomy closure, compared to interrupted methods, are associated with less short-term pain, are quicker and also need less suture material.

Absorbable suture materials for primary repair of episiotomy and second degree tears

BACKGROUND

Approximately 70% of women will experience perineal trauma following vaginal delivery and will require stitches. This may result in pain, suture removal and superficial dyspareunia.

OBJECTIVES

To assess the effects of different suture materials on short- and long-term morbidity following perineal repair.

SEARCH STRATEGY

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (February 2010).

SELECTION CRITERIA

Randomised trials comparing different suture materials for perineal repair after vaginal delivery.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data.

MAIN RESULTS

We included 18 trials with 10,171 women; comparisons included: catgut with standard synthetic (nine trials), rapidly absorbing synthetic (two trials), and glycerol impregnated catgut sutures (two trials); and standard synthetic sutures with rapidly absorbing synthetic (five trials) and monofilament sutures (one trial).Compared with catgut, standard synthetic sutures were associated with less pain up to three days after delivery (risk ratio (RR) 0.83, 95% confidence interval (CI) 0.76 to 0.90); and less analgesia up to ten days postpartum (RR 0.71, 95% CI 0.59 to 0.87). More women with catgut sutures required resuturing (15/1201) compared with synthetic sutures (3/1201) (RR 0.25, 95% CI 0.08 to 0.74); while more women with standard synthetic sutures required the removal of unabsorbed suture material (RR 1.81, 95% CI 1.46 to 2.24). Comparing standard synthetic with rapidly absorbing sutures, short- and long-term pain were similar; in one trial fewer women with rapidly absorbing sutures reported using analgesics at 10 days (RR 0.57, 95% CI 0.43 to 0.77). More women in the standard synthetic suture group required suture removal compared with those in the rapidly absorbed group (RR 0.24, 95% CI 0.15 to 0.36). There was no evidence of significant differences between groups for long-term pain (three months after delivery) or for dyspareunia at three, or at six to 12 months. When catgut and glycerol impregnated catgut were compared, results were similar for most outcomes, although the latter was associated with more short-term pain. One trial examining monofilament versus standard polyglycolic sutures found no differences for most outcomes.

AUTHORS' CONCLUSIONS

Catgut may increase short-term pain compared with synthetic sutures. There were few differences between standard and rapidly absorbing synthetic sutures but more women needed standard sutures removing. For other materials, there was insufficient evidence to draw conclusions. Findings should be interpreted in the context of the related Cochrane review on suturing techniques.
