Outcome of induction of labour with dinoprostone at a teaching hospital in Nepal

Abstract

Background: Induction of labour has now become a common practice; this study was conducted to find the outcome of induction of labour in pregnant women in relation to: induction delivery interval, mode of delivery, maternal complications and fetal outcome.Methods: It was a hospital based prospective study conducted from April 2012 to March 2013. Singleton pregnancy of gestational age ≥37 weeks, with vertex presentation and Bishops Score <6 were the cases included for induction. Dinoprostone (0.5mg) intracervically was used for induction. The different outcome parameters were analyzed.Results: Of 100 cases enrolled, majority 93% were below 30 years, mean gestational age of induction was 40.7± 0.7weeks and 58% were primi gravida. Ante natal care visit of ≥3 was present only in 66%. At induction 55% had bishop score of (0-3) and rest had score of (4-5). Postdated pregnancy (67%) followed by hypertension (13%) were the two most common causes for induction. 58% required second dose of dinoprostone, and the induction delivery interval was 24.3±9.6 hrs. 63% of the induced labour progress for vaginal delivery. Fetal distress (56.4%) was the commonest indication for caesarean section (CS). 6% of the cases had postpartum hemorrhage. 13% of the delivered neonate required NICU care, of which 53.8% was moderately asphyxiated. There was no maternal or neonatal death.Conclusions: In pregnancy undergoing induction of labour, CS is not uncommon, and there are few chances of maternal and neonatal morbidities. Therefore, obstetrician should be vigilant to avoid any untoward events.
