A randomized control trial evaluating the prevalence of obstetrical anal sphincter injuries in primigravida in routine versus selective mediolateral episiotomy.

Abstract

Routine mediolateral episiotomy in primigravida is associated with a higher prevalence of obstetrical anal sphincter injuries. As anal sphincter injuries are known to have morbidities, selective mediolateral episiotomy in primigravida is therefore recommended in the implementation of new delivery practice, and in an attempt to reduce our high episiotomy rate.
