Induction of labour in live singleton pregnancy: A comparative study between dinoprostone and oxytocin at a tertiary care hospital in Bihar

Abstract

Introduction: Post-term pregnancy is defined as gestation beyond 42 weeks from the first day of the last menstrual period. Previous studies have shown that as the gestational age advances beyond the expected delivery date, the risk of adverse maternal and fetal outcomes increases, including deterioration in coexisting maternal medical conditions, fetal distress, and fetal death. Materials and methods: An interventional study was planned by the Department of Obstetrics and Gynaecology, Darbhanga Medical College and Hospital, Laheriasri, Bihar. The study duration comprised of 6 months that is from January 2021 to June 2021. Women with viable singleton pregnanciesin late term gestation (41st week that was confirmed by crown-rump length measurement) who visited the hospital during the duration of data collection were recruited in the study after obtaining duly signed informed consent forms. Results: A total of 92 women with late-term pregnancy (LTP) were recruited into the study. They were divided randomly in group A and B, thus, each group comprised of 46 women. Based on bishop’s score, both groups were divided in subgroups A1, A2 and B1, B2. However, for women with a Bishop’s score between 4–6, there was no significant difference in the rate of cesarean delivery between subgroup B2 and A2 (P>0.05). Conclusion: Based on the study findings, the researcher conclude that in set up where dinoprostone is unavailable, oxytocin may be considered, rather than a cesarean section, for women with a Bishop’s score of 4–6.
