Pre-Induction and Intrapartum Correlates of Successful Induction Of Labour Using Oxytocin and Misoprostol in Abakaliki, Nigeria

Abstract

Context: Induction of labour (IOL) is a therapeutic challenge and an alternative to Caesarean section. Objectives: To evaluate the success rate of IOL and its determinants at the Ebonyi State University Teaching Hospital (EBSUTH), Abakaliki. Methods: A retrospective study involving 251 parturients who had induction of labour over a five-year period. Results: IOL accounted for 2.9% of the 8,676 deliveries during the study period.

IOL using Misoprostol had a success rate of 83.1% and Oxytocin titration with synchronous fore water amniotomy 83.1%.

Factors influencing outcome included parity, booking status, gestational age, pre-induction cervical status and latent period interval. Conclusion: Induction of labour EBSUTH had a high success rate of 83.1%.
