Mediolateral Episiotomy: Technique, Practice, and Training

The Effect of Virtual Reality Application on Pain and Anxiety During Episiotomy Repair: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

INTRODUCTION AND HYPOTHESIS

There is a rising trend among women towards nonpharmacological approaches owing to their minimally invasive nature and limited adverse effects. Virtual reality (VR) has recently gained popularity as a new technology for reducing pain and anxiety in medical settings. Our research sought to investigate the impact of VR on pain and anxiety levels while undergoing episiotomy repair.

METHODS

A comprehensive search was carried out across PubMed, Scopus, Cochrane Library, and ISI Web of Science to find relevant randomized clinical trials (RCTs) up to January 2024. These trials investigated the use of VR as a treatment during episiotomy repair compared with a control group that did not receive VR intervention. Meta-analysis was performed using Review Manager software to analyze the data collected. Our primary outcomes were pain scores reported during and after episiotomy repair measured by a visual analog scale. Secondary outcomes analyzed included anxiety scores during and after the procedure, as well as the duration of episiotomy repair.

RESULTS

Seven RCTs, involving 578 patients, met the inclusion criteria. VR resulted in a significant reduction in pain scores both during and after episiotomy repair (p < 0.001). Additionally, anxiety levels during and after the procedure were significantly reduced in the VR group compared with the control group. Moreover, the duration of episiotomy repair was significantly shorter in the VR group.

CONCLUSION

Using VR has proven to be an effective technique in reducing pain and anxiety during and after episiotomy repair, as well as potentially speeding up the procedure.

The effect of Camellia sinensis ointment on perineal pain and episiotomy wound healing in primiparous women: A triple-blind randomized clinical trial

BACKGROUND AND OBJECTIVE

Episiotomy is one of the most commonly performed procedures in obstetrics. complications of episiotomy are pain, bleeding, infection, pain in the sitting position, and difficulty in taking care of the baby. This study aimed to investigate the effect of Camellia sinensis ointment on perineal pain and episiotomy wound healing in primiparous women.

METHODS

This triple-blinded randomized clinical trial was conducted on 60 primiparous women who were referred to the maternity ward of Al-Hadi hospital in Shoushtar and Ganjovian hospital in Dezful, Iran, from 2020 to 2021. Participants were randomly assigned into two groups of intervention (Camellia sinensis extract ointment) and control (placebo) with a follow-up of 14 days. REEDA scale (redness, edema, ecchymosis, discharge, and approximation) was used to measure wound healing and the Visual Analog Scale (VAS) was used to measure the pain intensity.

RESULTS

There was no significant difference between two groups before intervention in terms of sociodemographic characteristics, pain intensity, and episiotomy wound status. Scores of pain intensity and wound healing reduced on days 7, 10, and 14 post-intervention in the intervention group compared to placebo. There was a significant decrease between the groups of intervention and control in terms of the mean score of pain intensity (VAS scale) on day 10 (1.33 ± 0.71, 1.77 ± 0.93) and day 14 (0.73 ± 0.74, 1.13 ± 0.81) post-intervention (P < 0.05). Also, on day 14 post-intervention, there was a significant decrease between the groups of intervention and control in terms of the mean score of episiotomy wound healing (REEDA index) (0.53 ± 0.77, 1.77 ± 1.46) (P < 0.05). The GLM test was applied for repeated measures. REEDA index and VAS scale changed during different times (time-variable) (p < .001). But, the studied groups (group variable) and the studied groups (interaction effect of group * time) did not affect the changes in the REEDA index (p = .292, p = .306) and VAS scale (p = .47) during different times.

CONCLUSION

Our study showed that Camellia sinensis extract ointment has a small effect on the healing process and pain reduction of episiotomy wounds. to confirm its effect, a study with a larger sample size should be conducted.

Re-evaluation of modifiable risk factors for obstetric anal sphincter injury in a real-world setting

INTRODUCTION AND HYPOTHESIS

The objective was to identify modifiable risk factors for obstetric anal sphincter injury (OASI) in primiparous women.

METHODS

This was a retrospective cohort study of primiparous women with a singleton vaginal delivery. Main outcome measures were incidence of OASI and odds ratios for possible risk factors: maternal age, body mass index and height, fetal birthweight and head circumference, gestational age, epidural analgesia, mediolateral episiotomy, and instrumental deliveries. Univariate and multivariate logistic regressions were performed using forward methods for variable selection.

RESULTS

Of 19,786 primiparous women with a singleton vaginal delivery, 369 sustained an OASI (1.9%). Risk factors were identified: vacuum extraction (adjusted OR 2.06, 95% CI, 1.59-2.65, p < 0.001), increased fetal weight (aOR 1.06, 95% CI, 1.02-1.11, p = 0.002, per 100-g increments); head circumference (aOR 1.24, 95% CI, 1.13-1.35, p < 0.001, per 1-cm increments); gestational week (aOR 1.11, 95% CI, 1.02-1.2, p = 0.012, per week). Protective factors: mediolateral episiotomy (aOR 0.75, 95% CI, 0.59-0.94, p = 0.013) particularly in vacuum deliveries (aOR 0.50, 95% CI, 0.29-0.97, p = 0.040); epidural analgesia (aOR 0.64, 95% CI, 0.48-0.84, p = 0.001); maternal height ≥157 cm (aOR 0.97, 95% CI, 0.96-0.98, p = 0.006, risk decreases by 2.6% per 1 cm increase in height).

CONCLUSIONS

Mediolateral episiotomy was protective against OASI in both spontaneous and instrumental deliveries of primiparae. Increased fetal weight and large fetal head circumference, particularly in short women, were significant risk factors. These findings support the performance of ultrasound to acquire updated fetal measures before admission to the labor ward.

Patterns in Second Stage Labor Care Practices Associated With Genital Tract Injury and Postpartum Hemorrhage During Physiologic Birth: A Latent Mixture Model Analysis

INTRODUCTION

Genital tract injury during childbirth contributes to short and long-term problems, including postpartum hemorrhage, incontinence, and pelvic organ prolapse. The purpose of this study was to examine which sets of second stage management techniques employed by midwives attending births in the community setting are associated with genital tract injury and subsequent postpartum hemorrhage.

METHODS

Data from primiparous individuals within the Midwives Alliance of North America (MANA) Stats 2.0 (2004–2009) database were used for this analysis. Latent mixture modeling identified classes (groups) within the sample that are most similar based on 11 different characteristics of second stage management as noted by midwives in their birth notes, including hands-on management techniques during birth, maternal positioning at birth, and water birth.

RESULTS

Three classes of second stage management techniques best fit this complex dataset. The patterns of techniques used by midwives were only marginally associated with better or worse genital tract outcomes independent of other factors. Two covariables, however, advanced maternal age (OR1.60, 95% CI 1.09–2.34) and births with low fetal heart rate during second stage (OR2.82, 95% CI 1.93–4.10)—were associated with severe genital tract injury. Postpartum hemorrhage was more likely for the two classes where midwives used more hands-on management during second stage, even when considering presence of genital tract injury (OR1.33, 95% CI 1.09–1.63). This study highlights the complex second stage circumstances that interact with management techniques, which together shape or contribute to both genital tissue and hemorrhage outcomes.

Attitudes and knowledge regarding episiotomy use and technique in vacuum extraction: A web-based survey among doctors in Sweden

OBJECTIVES

Correct episiotomy use and technique may prevent obstetric anal sphincter injuries. We aimed to explore the attitudes, use, and technique regarding episiotomy among doctors in Sweden, and their willingness to contribute to a randomized controlled trial of lateral episiotomy or no episiotomy in vacuum extraction in nulliparous women.

STUDY DESIGN

A web-based survey was sent to members of the Swedish Society of Obstetrics and Gynecology (n = 2140). The survey included 31 questions addressing personal characteristics, use of episiotomy, a two-dimensional picture on which the respondents drew an episiotomy, and questions regarding attitudes towards episiotomy and participation in a randomized controlled trial. We calculated the proportion of supposedly protective episiotomies (fulfilling criteria of a lateral or mediolateral episiotomy and a length ≥ 30 mm). We compared the results between obstetricians, gynecologists, and residents using Chi-square and Kruskal-Wallis tests for differences between groups, and logistic regression to estimate the odds ratio (OR) of drawing a protective episiotomy.

RESULTS

We received 432 responses. Doctors without a vacuum delivery in the past year were excluded, leaving 384 respondents for further analyses. In all, 222 (57.8%) doctors reported use of episiotomy in<50% of vacuum extractions. We obtained 308 illustrated episiotomies with a median angle of 53°, incision point distance from the midline of 21 mm, and length of 36 mm, corresponding to a lateral episiotomy. Few doctors combined these parameters correctly resulting in 167 (54.2%) incorrectly drawn episiotomies. Residents drew shorter episiotomies than obstetricians and gynecologists. Doctors ranked episiotomy the least important intervention to prevent obstetric anal sphincter injuries in vacuum extraction. Doctors contributing to an ongoing randomized controlled trial of lateral episiotomy or no episiotomy in vacuum extraction were more able to draw a protective episiotomy (OR 3.69, 95% confidence interval 1.94-7.02).

CONCLUSIONS

Doctors in Sweden reported restrictive use of episiotomy in vacuum extraction and depicted lateral type episiotomies, although the majority were incorrectly drawn. Preventive episiotomy was ranked of low importance. Our results imply a need for education, training, and guidelines to increase uptake of correct episiotomy technique, which could result in improved prevention of obstetric anal sphincter injuries.

Trend and Inequality in Episiotomy in Southern Brazil, 2007-2016: Evidence of Reduced Abusive Practice

OBJECTIVES

This study aimed to measure the prevalence, to describe the trend over time, and to evaluate socioeconomic inequalities in the occurrence of episiotomies in 2007, 2010, 2013, and 2016 in the municipality of Rio Grande, in Southern Brazil.

METHODS

We included all women who had vaginal delivery in each of the studied years. All the information was obtained through a questionnaire applied at maternity wards within 48 h after delivery. The outcome consisted of episiotomy. A chi-square test was used to evaluate the linear trend. Absolute and relative inequalities were assessed from household income and schooling of the women through the Slope Index of Inequality and Relative Index of Inequality, respectively.

RESULTS

This study included 4,521 parturients. The episiotomy rate in the period fell from 71.0% (95%CI: 68.4-73.5) in 2007 to 40.1% (95%CI: 37.3-42.8) in 2016, and it was more frequent among women with higher income and higher schooling. We observed a reduction in the rate of episiotomy in all income and schooling levels, and this was more evident among women in the lowest socioeconomic levels. Absolute inequality declined, while relative inequality remained unchanged.

CONCLUSIONS FOR PRACTICE

Despite the significant reduction in the rate of episiotomy, its occurrence remains high. Women with higher income and education, therefore with lower risk for complications during childbirth, were the most frequently submitted to this procedure. Routine use of episiotomy must be reevaluated, especially among pregnant women with better socioeconomic status.

Evaluation of midwifery pelvic floor education and Training across the UK and Spain

OBJECTIVES

The aim of this study was to evaluate current education and training of student and registered midwives across the UK and Spain; analysing both pelvic floor teaching and practical experience.

STUDY DESIGN

A cross-sectional survey was carried out by 711 student and 384 registered midwives across different universities and regions in the UK and Spain.

RESULTS

The vast majority (91.5 % n = 382) of UK students complete training without ever cutting or repairing an episiotomy. This compares to 39.4 % (n = 85) of registered midwives who did not cut an episiotomy during training. Only 20 % (n = 9) of Spanish and 10 % (n = 45) of UK registered midwives felt confident undertaking these techniques. In Spain just 15 % (n = 6) of students, compared to 54.8 % (n = 80) of registered midwives had received teaching on longer-term pelvic floor complications.

CONCLUSION

There is a considerable deficit in the current training practices for midwives regarding episiotomies. This lack of practice and confidence may be impacting on the increased rates of perineal tears and pelvic dysfunction in post-partum women. Across registered midwives there are gaps in education regarding longer-term pelvic floor complications. Our study was limited by a smaller sample size from Spain compared to the UK. Our results show practical assessment of skills during training is desirable and could improve both the confidence and competence of midwives upon registration.
