Comparison of oral mifepristone with intracervical foleys catheterisation for induction of labour in term pregnancy: A randomized control trial

Abstract

The purpose of this study is to compare the efficacy of oral Mifepristone with the efficacy of intracervical Foley catheterisation for induction of labour in term pregnancy. The primary outcome of this study is to compare both methods of induction of labour in terms of induction to delivery interval and the secondary outcome is to compare the two methods in terms of route of delivery, indications of caesarean section and the neonatal outcomes. This study is a randomized control trial conducted from May 2022 to December 2022 in Department of Obstetrics and Gynecology, SSG Hospital, Baroda Medical College. 180 term pregnant patients were enrolled in this study based on a pre-established criteria. Patients were randomised into group A and B. Group A included patients who were given Tablet Mifepristone 200 mg PO followed by per vaginum Tablet Misoprostol and Group B included patients who underwent intracervical Foleys catheterisation followed by placement of per vaginum Tablet Misoprostol. The study concluded that there was significantly decreased induction-delivery interval in women induced with intracervical Foleys catheterisation (Group B) as compared to those given oral Tablet Mifepristone (Group A). There was no significant difference between the two groups in terms of the route of delivery, rate of C Sections and neonatal outcomes.Mifepristone is effective for inducing indicated term pregnancies, despite no decrease in induction delivery interval. Incidence of fetal distress with oral Mifepristone is comparable to intracervical foley's catheterization. Further research is needed to assess tachysystole/hyperstimulation and fetal distress caused by Mifepristone.
