STUDY TO COMPARE THE EFFICACY OF PROSTAGLANDINS AND EXTRA AMNIOTIC BALLOON CATHETER METHODS FOR INDUCTION OF LABOUR.

Abstract

Induction of labour is probably the most used obstetrical intervention, first described by the ancient Greek physician Hippocrates. Induction implies stimulation of contractions before the spontaneous onset of labour, with or without ruptured membranes. The purpose of induction of labour as compared to continuation is to end the pregnancy through vaginal delivery, in situations where pregnancy termination is expected to reduce risks to the mother or her baby. There are several different methods for cervical ripening, that can be categorized in mechanical (Foleycatheter) & pharmacological (prostaglandins). The aim of this study is to compare the efficacy of prostaglandins and extra amniotic balloon catheter for successful induction of labour. The comparative study was conducted in labour room of Patna Medical College Hospital, Dept of Obs & Gynae. All 100 pregnant women after 28 completed weeks of gestation were randomly allocated in two groups: Group A & Group B. GROUP A: induction with prostaglandins (PGE2 gel & misoprostol) GROUP B: induction with extra amniotic balloon of Foley’s catheter. The data was presented as mean standard deviation (SD) or percentage. Student’s unpaired t test and Chi square test were used to compare data between the two groups. In the present study, it was observed that the induction-labour interval and induction-delivery interval are less in extra amniotic balloon catheter group as compared to prostaglandins. There is no difference in caesarean section rate, neonatal mortality and morbidity when compared to prostaglandins.  It can be a safe alternative to prostaglandins Also it can safely be used in patients where prostaglandins are contraindicated (previous caesarean section).

Key words: Prostaglandins, Balloon catheter, Induction of labour.
