Abstract

Objective The objective was to determine whether discontinuation of oxytocin infusion after established active phase of induced labor gives good obstetric outcome without any adverse maternal and neonatal effect. Background Oxytocin is one of the most widely drugs used in induction of labor. Continuous infusion of oxytocin after establishment of the active phase of labor may lead to uterine atony and postpartum hemorrhage. Therefore, we should stop oxytocin infusion once the active phase has started. Patients and methods A total of 90 pregnant women who required labor induction and fulfilled the criteria of the study population were enlisted in this prospective controlled randomized clinical trial and then were assigned to either group A or B. In group A cases, infusion of oxytocin was started in incremental doses until 5 cm of cervical dilatation and to be maintained at that level throughout the labor, whereas in group B cases, infusion of oxytocin was started incrementally but discontinued when cervical dilatation reached 5 cm. Results This study showed that there was a statistically significant difference between group A and group B regarding the first stage of labor, uterine hyperstimulation, maximal and total doses of oxytocin, neonatal outcome, and incidence of postpartum hemorrhage. There was statistically insignificant difference between group A and group B regarding age, BMI, mean gestational age, parity, indications for induction of labor, detection of meconium upon rupture of membranes, and mode of delivery. Conclusion There is no need to continue oxytocin infusion after the establishment of active phase of labor.
