Abstract: Background: Induction of labour involves the artificial initiation of uterine contractions before their spontaneous onset. In recent decades, Induction of Labour (IOL) has been on a rise due to various indications. This study was conducted to access the rising rates of induction of labour at our hospital and the corresponding increase in caesarean section (CS) rates.
Methodology: This was a retrospective observational study involving 200 consecutive consenting women who delivered after induction of labour at a tertiary care centre.
Results:Premature Rupture of Membranes was the commonest indication (47%) of induction followed by post datism (20.50%) and oligohydramnios (18%). Successful induction will be defined as patients who went into “active labour (cervical dilataion of ≥ 4cm)” following an attempt of induction. 67% had successful outcome of the induction and went into active labour, 25% had incomplete attempt of induction and were delivered by CS due to various indications and 8% had failed induction despite three attempts of induction. Overall, 58.5% underwent a vaginal delivery, 39.5% underwent an emergency CS and 2% underwent an operative vaginal delivery. Among the 134 successful inductions, 87.31% of them underwent vaginal delivery, 2.99% underwent operative vaginal delivery for poor maternal bear down and 9.7% underwent emergency CS for various indications. Vaginal delivery rate is 87.31% in successful induction and 58.5% in total induction of labour. There was a significant association between hypertension and PROM as an indication of induction and the outcome of induction with hypertension showing a trend toward poorer outcomes and PROM showing better outcomes. There was a significant association between hypertension as an indication of induction and the mode of delivery especially with predominance towards CS.
Conclusion: Complications or failure of induction of labour, contributing to higher CS rates can be significantly mitigated through careful patient selection, meticulous monitoring, and comprehensive fetal assessment, optimizing outcomes for both mother and child.
