目的:探讨小容量宫颈球囊扩张器用于足月妊娠促宫颈成熟和引产的效果。方法:将具有引产指征的足月妊娠孕妇120例按随机数字表法分为研究组和对照组,每组60例,研究组采用小容量宫颈球囊扩张器促宫颈成熟并引产,对照组采用欣普贝生促宫颈成熟并引产,比较两组干预前后宫颈Bishop评分、引产开始至规律性宫缩时间及产程时间,并比较两组宫缩过强发生率和剖宫产率,记录两组产程出血量、产后出血量、新生儿体重和Apgar评分,并进行组间比较。结果:两组各时间点宫颈Bishop评分差异均无统计学意义(P>0.05);第一、二产程和总产程时间差异均无统计学意义(P>0.05);研究组引产至规律性宫缩开始时间短于对照组(P<0.01),子宫过强收缩发生率、胎心异常发生率及剖宫产率均低于对照组,差异均有统计学意义(P<0.05);两组产程和产后出血量、新生儿体重及出生后Apgar评分差异无统计学意义(P>0.05)。结论:小容量宫颈球囊扩张器促宫颈成熟效果与欣普贝生相似,但其安全性更好,有临床推广应用价值。
Objective: To investigate the effect of small-capacity cervical balloon dilator for full-term pregnancy to promote cervical ripening and induction of labor. Methods: 120 full-term pregnant women with induction of labor induction were divided into study group and control group according to random number table method, 60 cases in each group. The study group used a small capacity cervical balloon dilator to promote cervical ripening and induced abortion. The control group Cervical maturation and induction of labor were induced by Enbeek. The Bishop score of cervical before and after intervention, the time of induction of labor to regular contractions and the duration of labor were compared. The incidences of uterine contractions and cesarean section were compared between the two groups Group of bleeding, postpartum hemorrhage, neonatal weight and Apgar scores, and compared between groups. Results: There was no significant difference in cervical Bishop score between the two groups at each time point (P> 0.05). There was no significant difference in the first, second stage of labor and total labor duration (P> 0.05) (P <0.01), the incidence of uterine over-contraction, abnormal fetal heart rate and cesarean section rate were lower than the control group, the difference was statistically significant (P <0.05); two groups Labor and postpartum bleeding, neonatal body weight and postnatal Apgar score was no significant difference (P> 0.05). Conclusions: Small capacity cervical balloon dilator can promote cervix maturation effect similar to that of Hinbutsone, but its safety is better and it has clinical application value.
