Comparative study of induction of labour with dinoprostone gel versus mechanical dilatation in unfavorable cervix (low Bishops Score)

Background Induction of labour is a common procedure in obstetrics, occurring in upto 30% of pregnancies. Objective of present study was to compare the efficacy of double balloon transcervical catheter to that of a PG vaginal insert among women undergoing labour induction in terms of singleton pregnancies of both nulliparous and multiparous women with an unfavorable cervix.

Methods Patient admitted for induction of labour were randomized to receive intravaginal dinoprostone or intracervical Foley’s catheter. Patient not entering active labour and having rupture membranes or arrest of dilatation received IV oxytocin.

Results 150 patients received dinoprostone gel (group A) and 150 patients received Foleys catheter no.18 (group B). The mean time until cervix ripening was less in group A group (0.0001-p value). The mean time until vaginal delivery was less in the Group A group (p value-0.010) among vaginal deliveries more patients in the Group A group delivered within 24 hours (0.0001-P value.). There was significant differences in cesarean delivery rates (8% vs 20.66%, P value-0.0001, sig). Oxytocins is required in both groups (73.33% vs. 78.66%).

Conclusions Group A was associated with more rapid cervical ripening, shorten induction to vaginal delivery interval and greater no. of vaginal deliveries within 24 hours.
