Influence of Maternal Factors on Labour Induction Outcomes

Abstract

Background and Aim: Induction of labour (IOL) plays a crucial role in minimising negative outcomes for both mothers and newborns. Improved pregnancy outcomes are particularly notable in resource-limited countries, where the rates of maternal and perinatal mortality remain unacceptably high. This research aimed to pinpoint the elements influencing both the success and failure of labour induction, with the goal of enhancing the quality of the procedure and reducing unwarranted indications for its use.

Materials and Methods: The research focused on expectant mothers and their newborns. A total of 160 participants were involved in the study. The study examined various maternal parameters, including age, parity, gestational age, BMI, Bishop score, reasons for induction, induction methods, delivery modes, and maternal complications. Additionally, neonatal parameters such as Apgar score, birth weight, and NICU admissions were also analysed.

Results: The findings indicate that the vaginal delivery rate was 47.27% for those delivering between 37 and 40 weeks, compared to a significantly higher rate of 76% for deliveries occurring beyond 40 to 42 weeks. The rate of vaginal delivery among women with premature rupture of membranes and those who are postdates was notably high, recorded at 68.42%. A Bishop score of less than 5 was linked to a notably elevated rate of caesarean sections, while a score of 5 or higher correlated with a high rate of vaginal deliveries, reaching 93.75%.

Conclusion: The study revealed that the success rate of inducing labour to achieve vaginal delivery stood at 56.25%. Women under 30 years of age, Multigravidas, gestational age between 40 and 42 weeks gestation, Bishop Score above 5 showed a significant correlation with successful labour induction.
