Effectiveness of Dinoprostone and Cook’s Balloon for Labor Induction in Primipara Women at Term

Summary Labor induction is commonly used for achieving successful vaginal delivery. This study aimed to compare the effectiveness of dinoprostone and Cook’s balloon as labor-inducing agents in primipara women at term. A retrospective cohort study among primipara women was conducted in Hubei Maternity and Child Health Hospital. Basic clinical characteristics were collected. The main outcomes were vaginal delivery rate, cesarean section rate and forceps delivery rate. Obstetric and perinatal outcomes were also compared. Univariate and multivariate analyses were further performed to evaluate the predictors for vaginal delivery within 24 h. A total of 845 eligible primipara women undergoing labor induction were recruited. Of them, 141 women were induced with dinoprostone (dinoprostone group, DG), and 704 with Cook’s balloon (Cook’s balloon group, CG). Groups were homogeneous except more women with premature rupture of membranes in DG, with gestational hypertension in CG ( P
