AI Article Synopsis
- This study investigated the impact of episiotomy on maternal and neonatal complications during instrumental vaginal deliveries in Dundee, Scotland, involving over 2,100 women.
- Results showed that while vacuum delivery had a lower episiotomy rate, the use of episiotomy significantly increased the likelihood of extensive perineal tears and neonatal trauma compared to deliveries without episiotomy.
- The study concluded that episiotomy does not reduce the risk of shoulder dystocia and raises the risk of severe perineal injuries, questioning its routine use in this context.
Article Abstract
Objective: The aim of this study was to investigate the maternal and neonatal morbidity related to use of episiotomy for vacuum and forceps deliveries.
Design: Retrospective population-based cohort study.
Setting: Dundee, Scotland.
Population: Two thousand one hundred and fifty three women who experienced an instrumental vaginal delivery between January 1998 and December 2002.
Methods: Univariate and multivariate logistic regression analyses were performed comparing deliveries with and without the use of episiotomy.
Main Outcome Measures: Extensive perineal tears (third and fourth degree) and shoulder dystocia.
Results: Two hundred and forty-one (11%) of the 2153 women who underwent instrumental vaginal deliveries did not receive an episiotomy. Vacuum delivery was associated with less use of episiotomy compared with forceps (odds ratio 0.10, 95% CI 0.07-0.14). Extensive perineal tears were more likely with use of episiotomy (7.5%vs 2.5%, adjusted OR 2.92, 95% CI 1.27-6.72) as was neonatal trauma (6.0%vs 1.7%, adjusted OR 2.62, 95% CI 1.05-6.54). Use of episiotomy did not reduce the risk of shoulder dystocia (6.9%vs 4.6%, adjusted OR 1.43, 95% CI 0.74-2.76). The findings were similar for delivery by vacuum and forceps.
Conclusion: The use of episiotomy increased the risk of extensive perineal tears without a reduction in the risk of shoulder dystocia.

Background: Induction of labour (IOL) is a common obstetric intervention in the UK, affecting up to 33% of deliveries. IOL aims to achieve a vaginal delivery prior to spontaneous onset of labour to prevent harm from ongoing pregnancy complications and is known to prevent stillbirths and reduce neonatal intensive care unit admissions. However, IOL doesn't come without risk and overall, 20% of mothers having an induction will still require a caesarean section birth and in primiparous mothers this rate is even higher.

Background: The French guidelines have recommended a restrictive policy of episiotomy since 2005. We aimed to assess variations in the prevalence of both episiotomy and obstetric anal sphincter injury (OASI) from the 2010, 2016, and 2021 National Perinatal Surveys.
Methods And Findings: A total of 29,750 women who had given birth to a live infant by vaginal delivery were included.

Background: Although consent has long been accepted as necessary in maternity care, the concept of informed consent for planned vaginal birth has polarised maternity politics. The publication of the NSW Consent Manual outlines new standards of informed consent, signalling the need for examination of current maternity consent practices.
Aims: To examine informed consent and disclosure of material risks in birth in a prospective qualitative study of midwives and obstetricians.
