Perineal Outcome after Restrictive use of Episiotomy in Primi-gravidas

Abstract

Introduction: Episiotomy is a common obstetrical practice that is believed to prevent severe lacerations.
Principles of evidence based medicine raises questions on the utility of routine episiotomy.

Methods: A prospective observational study was conducted in primi gravidas coming to Tansen Mission Hospital for delivery who were not offered episiotomy sticking to the protocol of restrictive use of episiotomy and the subsequent perineal tear was evaluated in terms of its length, degree and complications. Risk factors associated with significant degrees of perineal tear was investigated.

Results: The episiotomy rate during the time of study was only 22%. Among those included in the study, 16.2% of women had intact perineum and majority of women (43.2%) had first degree of tear. Only one (1.4%) had third degree tear without any long term complications. Having a baby weighing 2.5 kg increases the mean tear length significantly (P=0.019) and increases the risk of having second or third degree of tear by almost two times (Relative Risk=1.95). No clinically significant complications were observed in any of the women after the delivery.

Conclusions: This study provides some evidence that the principle of restrictive use of episiotomy with a total episiotomy rate being around 20% can be carried out successfully even in an under¬resourced setting of our country.
