Abstract


Background: The aim of induction of labour is to achieve vaginal delivery in advance of the normal timing of parturition and to avoid operative delivery. The objective was to study the incidence of instrumental delivery and cesarean section in nulliparous women with unfavourable bishops score at term.

Methods: This study was conducted on 200 patients in nulliparous women with unfavourable bishop score, cephalic presentation and no previous history of abortion.

Results: The most frequent cause of induction of labour was postdatism (47.5%) followed by PIH (25.5%) and PROM (13%). 143 (71.5%) women had normal vaginal delivery whereas in 54 women (27%) cesarean section was done. 2 women (1%) had forceps application for delivery and remaining 1 women (0.5%) had ventouse delivery. Out of 200 patients 9 had maternal complication of induction of labour.

Conclusions: In present study 71.5% women had normal vaginal delivery, 27% had cesarean section. Mean bishop score at induction was 3.31 which improved to 4.0 after 12 hours of gel instillation. The mean induction to delivery interval was 13.38 hrs in present study, 54.5% patients were delivered within 12 hours of gel instillation in this study. Most common indication of cesarean section was failed progress followed by fetal distress.
