Objective: To explore the effect of cervical dilatation balloon on the outcome of induction of labor in term pregnant women with immature cervix. Methods: The data of 207 full-term pregnant women with cervical immaturity treated in the Department of Gynecology and Obstetrics at the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from February 2019 to October 2021 was analyzed retrospectively. Among them, 103 cases received oxytocin to promote cervical maturity (oxytocin group), and 104 cases received cervical dilation balloon to promote cervical maturity (balloon group). The perinatal related outcome indicators between the 2 groups were sorted out and compared. Results: The total effective rate and Bishop score of promoting cervical maturation in the balloon group were significantly higher than those in the oxytocin group (92.31% vs 82.52%, 7.17±1.05 vs 6.86±0.92, both P<0.05). The labor time (21.40±3.57) h and labor process time (9.26±2.28) h in the balloon group were significantly shorter than those in the oxytocin group [(26.58±3.91) h and (11.43±2.71) h]. The success rate of induced labor was 88.46%, which was significantly higher than 77.67% in the oxytocin group (P<0.05). There was no significant difference in the incidence of adverse outcomes between the 2 groups (P>0.05). Conclusion: Cervical dilatation balloon is better than oxytocin in promoting cervical maturity in full-term pregnant women with immature cervix. It can accelerate the process of labor, improve the success rate of induced labor, and reduce unnecessary cesarean section.
