Objectives: To determine the common indications and obstetric outcome of induction of labour at the MCH Center. Design: A retrospective audit of all pregnant women undergoing induction of labour from 1st January 1999 to 31st December 1999. Setting: The study was conducted at the labour ward at the MCH Center, PIMS, Islamabad. 615 pregnant women requiring induction of labour in 2nd and 3rd trimesters. Outcome measures: Frequency of various indications for induction of labour, the induction agents used as well as the parity, gestational age and the mode of delivery in the women with induced labour. Results: Of 3071 deliveries, 615 (20%) required induction of labour. The commonest indication for induction of labour was post dates 217 (35.3%) followed by pre-labor rupture of membranes 129 (21%), hypertension 87 (14%) and intrauterine death (IUD) 61(10%). Prostaglandin E2 vaginal pessary was the most commonly used induction agent in 375 (61%) women while 122 (20%) had mechanical method of induction. Artificial rupture of membranes along with syntocinon infusion was used in 45 (7%) and extra-amniotic Prostaglandin F2a in 29 (5%). In 90 (15%) patients the data for mode of delivery was incomplete. Among the rest of the 525 patients the mode of delivery was spontaneous vaginal delivery in 428 (82%), instrumental vaginal delivery in 34 (6%), vaginal breech delivery in 10 (2%) and cesarean section for 53 (10%) patients. Conclusions: The commonest indication for labour induction was postdates. As 10% of patients requiring labour induction had IUD and 14% had gestation less than 34 weeks the overall LSCS rate remained low (10%) in this high risk group.
