Outcome of Induction and Associated Factors among Term and Post- Term Mothers Managed at Jimma University Specialized Hospital A Two Years’ Retrospective Analysis

Abstract

BACKGROUND: Induction of labor using oxytocin is a routine procedure in obstetrics used for vaginaldelivery of gravid uterus. The purpose of this study was to analyze outcome of induction with oxytocinand associated factors among mothers who delivered at term and post-term in Jimma UniversitySpecialized Hospital, Southwest Ethiopia.METHODS: A facility based cross-sectional study was conducted on records of 280 laboring motherswho delivered at term and post-term after induction with oxytocin from September 1 st , 2009 to August31 st , 2011. The data were extracted using checklist and analyzed using SPSS windows version 16.0. Thelevel of significance to declare relationship between the dependent and independent variables was set atp< 0.05.RESULTS: Mean maximum oxytocin levels used until vaginal delivery and at time of diagnosis of failedinduction were 55.0 ± 29.8 and 89.7± 11.6 miu/min respectively. Mean time elapsed from initiation ofinduction with oxytocin to vaginal delivery and till diagnosis of failed induction were 6:10 ± 3:09 and9:57± 2:01 hours respectively. Failed induction was diagnosed in 21.4% of the mothers. Primigravidity,unfavorable and intermediate Bishop Scores determined at admission were found to be predictors offailed induction.CONCLUSION: High rate of failed induction and high level of oxytocin use were found. Preparation ofthe cervix before commencing induction in primigravid women is recommended to improve success ofinduction with the current protocol.
