双球囊足月妊娠引产中催产素应用时机的研究

Study on the application timing of oxytocin during induction of labor by double-balloon of primiparas with full-term pregnancy

目的:探究足月妊娠妇女采用双球囊联合催产素引产时催产素的应用时机。方法:取2019年6月-2020年6月于本院定期产检并分娩的60例无合并症及并发症的初产妇,按随机数字表法分为双球囊后12小时给予催产素组(A组)、双球囊后1小时给予同时催产素组(B组)。分析比较两组产妇的Bishop评分变化及相关分娩结局。结果:两组引产前Bishop评分无差异,引产后Bishop评分B组高于A组(P<0.05);A组30例初产妇中7例转为剖宫产,B组3例,其余两组产妇比较,B组第一产程及总产程较A组短(P<0.05),且两组分娩相关并发症发生率并无差异。结论:双球囊同时加入催产素用于足月初产妇的引产更有效。

Objective: To explore the application timing of oxytocin during induction of labor by double-balloon of primiparas with full-term pregnancy. Methods: A total of 60 primiparas without comorbidities and complications who underwent regular obstetric examination and delivery in hospital were selected and were divided into group A(primiparas were given double balloon followed by oxytocin) and group B(primiparas were given double balloon and oxytocin in the same time) according to the random number table method from June 2019 to June 2020. The change of Bishop score and related delivery outcomes of the primiparas were analyzed and compared between the two groups. Results: There was no significant difference in Bishop score of the primiparas before induction of labor between the two groups. After induction of labor, the Bishop score of the primiparas in group B was significantly higher than that of the primiparas in group A(P<0.05). Among the 30 primiparas in group A, 7 cases were converted to cesarean section, and among the 30 primiparas in group B, 3 cases were converted to cesarean section. The first and the total stages of labor of the primiparas without converted to cesarean section in group B were significantly shorter than those of the primiparas in group A(P<0.05), and there was no significant differences in the incidences of labor-related complications of the primiparas between the two groups. Conclusion: The double balloons and oxytocin used in the same time for induction of labor of the primiparas with full-term pregnancy has better effectiveness.
