目的探讨双球囊导管在足月妊娠促宫颈成熟和引产中的应用效果。方法选取215例足月妊娠孕妇作为研究对象,其中应用双球囊导管促宫颈成熟和引产的135例孕妇为观察组,直接应用缩宫素静滴引产的80例孕妇为对照组。比较两组的促宫颈成熟率（宫颈Bishop评分）、诱发临产时间、总产程时间,以及分娩方式和分娩结局。结果两组干预前宫颈Bishop评分无统计学差异（P〉0.05）,干预后观察组的宫颈Bishop评分显著高于对照组（P〈0.05）。观察组的阴道分娩率显著高于对照组（P〈0.05）,剖宫产率显著低于对照组（P〈0.05）,两组的产钳助产率无统计学差异（P〉0.05）;观察组的催产素使用率显著低于对照组（P〈0.05）。观察组子宫强直收缩率及新生儿窒息率均显著低于对照组（P〈0.05）,两组产后尿潴留的发生率、产后2 h出血量及新生儿体重均无统计学差异（P〉0.05）。结论应用双球囊导管在足月妊娠促宫颈成熟及引产方面具有良好的临床效果,可显著改善宫颈条件,提高阴道分娩率,缩短产程,减少新生儿并发症的发生。

英文摘要：

Objective To explore the application effect of double balloon catheter in cervical maturity promotion and induced labor of full-term pregnancy. Methods A total of 21 5 cases of pregnant women with full-term pregnancy were selected as research objects. 1 35 cases of pregnant women in the observation group were given double balloon catheter for cervical maturity promotion and induced labor,while 80 cases of pregnant women in the control group were given intravenous infusion with pitocin. The cervical maturity promotion rate（cervical B ishop score）, induced labor time, total labor time, delivery mode and birth outcomes of both groups were compared. Results B efore intervention, there was no statistical difference in cervical Bishop score between two groups（P〉0.05）; after intervention, the B ishop score of observation group was significantly higher than that of control group（P〈0.05）. The vaginal birth rate of observation group was significantly higher than that of control group, and the cesarean section rate was significantly lower than that of control group（P〈0.05）; No statistical difference was found between two groups in the forceps midwifery rate（P〈0.05）; The pitocin usage rate of observation group was significantly lower than that of control group（P〈0.05）. The incidences of stiffness reduction of the uterus and newborn asphyxia of observation group were significantly lower than those of control group（P〈0.05）, while no statistical difference was found between two groups in the incidence of postpartum urinary retention, 2-hour postpartum hemorrhage and neonatal weight（P〉0.05）. Conclusions The application effect of double balloon catheter in cervical maturity promotion and induced labor of full-term pregnancy is significant, with significantly improving cervical condition, developing vaginal childbirth, shortening labor time and reducing neonatal complications.
