Episiotomy is associated with a reduced risk of obstetric anal sphincter injury in nulliparous vacuum‐assisted deliveries, particularly in high‐risk cases

Key Points

• To examine the impact of mediolateral episiotomy on the occurrence of obstetric anal sphincter injury during vacuum-assisted deliveries in nulliparous women.
• Analyzed nulliparous women undergoing vacuum-assisted deliveries
• Compared outcomes between those with and without episiotomy
• Evaluated intra-partum risk factors present during deliveries
• Mediolateral episiotomy associated with a 50% reduction in obstetric anal sphincter injury
• Greater preventive effect observed with multiple intrapartum risk factors
