Pak J Surg Jan ;37(3):212-5.

Objectives: To determine the factors responsible for failed induction of labour. Study design: Retrospective cross-sectional Study Study Setting: Obstetric and Gyne Department of Al-Aleem Medical College, Gulab Devi Educational Complex. Duration of study: One year from 1st October 2019 to 30th October 2020. Material and Methods: During this period total 690 births were carried out. A total of 301 pregnant women fulfilling inclusion criteria were included in this study who were induced. Data like age, parity, BMI, gestational age, ruptured membranes, amniotic fluid volume on US, Bishop`s score and fetal weight were recorded on pre-designed proforma. Results: A total of 301 women met the inclusion criteria, failed induction occurred in 123 women (40.86%). The mean age of the women was 28.3 +- 1.9 years. Factors responsible for failed induction of labour in the study were observed as women > 30 years 64.22%, primigravida 69.91%, BMI more than 24 k.g/m2 78.86%, gestational age > 41 weeks 40.65%, ruptured membranes > 12 hours 66.66%, Bishop score < 5 cm 69.91%, AFI on USG 56.09% and fetal weight > 3 kg 60.97%. The P-value was extremely statistically significant (< 0.0001) was observed in two factors ruptured membranes more than 12 hours and poor Bishop`s score. Conclusions: In our study induction of labour failed in 40.86%. Poor Bishop`s score < 5cm and ruptured membranes more than 12 hours at admission were observed extremely statistically significant factors.
