Abstract
AbstractAimsTo compare the efficacy of the controlled‐release dinoprostone delivery system (PROPESS) and Cook's double balloon catheter (DBC) plus oxytocin as induction treatment.MethodsA total of 197 term pregnant women with unfavorable cervix were admitted for scheduled induction and enrolled retrospectively (PROPESS, 113; Cook's DBC plus oxytocin, 84). The main birth outcomes were cervical ripening at the treatment‐end and 24 h after the treatment‐start, and rate of vaginal birth. Logistic regression and propensity score matching analyses were performed to evaluate the association between the outcomes and clinical characteristics including which treatment was selected.ResultsThe choice of PROPESS was associated with the success of cervical ripening at 24 h after (adjusted odds ratio (OR) 2.17, 95% confidence interval (CI) 1.11–4.26, p = 0.024) and increased the rate of vaginal birth (adjusted OR 2.03, 95% CI 1.04–3.98, p = 0.039). Similar trends in the association between PROPESS and birth outcomes were maintained after adjusting for propensity scores (p = 0.072 and p = 0.163, respectively). However, some of the women with gestational age of early 39 weeks and low Bishop scores could achieve cervical ripening at 24 h after using Cook's DBC plus oxytocin, and none by PROPESS.ConclusionOur findings suggest the possibility of slight advantages of PROPESS for scheduled induction of labor. In women with early term and extremely low Bishop scores, Cook's DBC plus oxytocin may be a superior or alternative treatment to PROPESS. Therefore, the optimal choice of induction treatment should be managed on an individual basis.
