Mean Induction to Delivery Interval with Concurrent Oxytocin in females While requiring second dose of Dinoprostone in Labour

Abstract

Objective: To assess the mean induction to delivery interval with concurrent oxytocin in females, while requiring a second dose of dinoprostone in labour.

Methodology: Descriptive case series study was conducted in Unit 4, Department of Obstetrics & Gynecology, Lady Aitchison Hospital, Lahore from July 2018 to Dec 2018. Female of age 18–35 years, primigravida, presenting at gestational age >37weeks on LMP, in labour (cervical os > 3cm). Then, females were given oxytocin infusions, at 1mu per minute (or 3 ml per hour) as starting dose, which was doubled each 30 minutes until up to maximum 32 mu per minute for achieving effective uterine contraction without foetal cardiac rate abnormalities. The time of the administration of oxytocin and dinoprostone was noted. Then females were followed up till delivery. At the time of delivery of the placenta, time was again noted. The induction delivery interval was calculated. All information was collected via study proforma.

Results: The mean induction delivery interval was 8.83±3.38 hours. Stratification of age and gestational age of women did not show a significant difference for mean induction delivery interval time. However, patients in the elderly age group (27-35 years) and higher gestational age (40–41 weeks) had short mean induction to delivery interval. Women with higher BMI had higher delivery interval as compared to women with lower BMI values.

Conclusion: Labour induction with concurrent oxytocin infusion and second dose of dinoprostone reduce/shorten the mean induction to delivery interval time. It will also help reduce the burden of obstetricians and early completion of delivery process.
