ABSTRACT
BACKGROUND:
The aim is to investigate the risk of short-term maternal morbidity caused by the selective clinical use of episiotomy (rate < 0.02), and to compare the risk of severe perineal tears with the statewide risk.METHODS:
In this retrospective cohort study, we investigated the effect of selective episiotomy on the risk of severe perineal tears and blood loss in singleton term deliveries, using propensity scores with inverse probability weighting.RESULTS:
This study included 10992 women who delivered vaginally between 2008-2018. Episiotomy was performed in 171 patients (1.55%), three of whom (1.75%) experienced severe perineal tears compared to 156 (1.44%) in the control cohort. The adjusted odds ratio of severe perineal tears was 2.06 (95% confidence interval [CI] 0.51, 8.19 with 0.3 p value). Multivariate linear regression showed that episiotomy increased blood loss by 96.3 ml (95% CI 6.4, 186.2 with 0.03 p value). Episiotomy was performed in 23% (95% CI 0.228, 0.23) of vaginal deliveries in the state of Hessen, with a risk of severe perineal tears of 0.0143 (95% CI 0.0139, 0.0147) compared to 0.0145 (95% CI 0.0123, 0.0168) in our entire cohort.CONCLUSIONS:
Selective use of episiotomy does not increase the risk of higher-grade perineal tears. However, it may be associated with maternal morbidity in terms of increased blood loss.
An episiotomy is a cut between the vagina and the anus that may be performed by an obstetrician during childbirth and can result in increased blood loss or severe birth tears. In this study, we investigated the risks of both bleeding and severe tears caused by a highly selective local practice of episiotomies below 2% and compared the results with statewide data. The study included 10992 women who delivered between 20082018, 171 of whom underwent episiotomies according to the hospital's protocols. Having an episiotomy did not increase the likelihood of severe birthing tears but was associated with an increase in estimated blood loss. Therefore, although highly selective use of episiotomy is unlikely to cause more severe tears, it has the potential to worsen the mother's health by increasing blood loss.
