宫颈扩张单球囊与双球囊在改善子宫颈条件中的作用

The role of cervical dilatation with single balloon and double balloon in improving cervical conditions

目的比较宫颈扩张单球囊与双球囊在促宫颈成熟中的作用。方法将本院406例具备引产指征的足月单胎产妇作为研究对象,随机分为观察组(给予宫颈扩张单球囊)和对照组(给予宫颈扩张双球囊),两组各203例。比较两组产妇宫颈改善及并发症的发生情况。结果两组宫颈改善有效率的比较,并无明显差异(χ^2=0.11,P>0.05);观察组自然临产率较对照组明显升高(χ^2=5.89,P<0.05);两组球囊放置至活跃期时间、分娩时间的比较,均无明显差异(t=0.09、0.14,均P>0.05);两组产后出血量的比较,并无明显差异(t=0.23,P>0.05);观察组剖宫产率较对照组明显降低(χ^2=4.04,P<0.05);两组宫内感染、脐带脱垂及新生儿窒息发生率的比较,均无明显差异(χ^2=0.68、0.32、0.19,均P>0.05)。结论宫颈扩张单球囊与双球囊在改善产妇子宫颈条件中均具有一定的作用,但相比宫颈扩张双球囊,应用宫颈扩张单球囊后能够明显提高产妇自然临产率,有效减轻剖宫产率,同时并不会增加不良反应的发生率,因此其对促宫颈成熟具有较高的作用。

Objective To compare the effects of single and double balloon dilatation in cervical ripening.Methods A total of 406 singleton pregnant women with indications of labor induction were selected in this hospital.406 cases were randomly divided into the observation group for single balloon of cervical dilatation and the control group received double balloon dilatation of cervical dilatation,with 203 cases in each group.The cervical improvement and complications were compared between the two groups.Results There was no significant difference in the efficient rate of cervical improvement betwenn the two groups(χ^2=0.11,P >0.05);natural labor rate of observation group was significantly higher than that of the control group (χ^2=5.89,P <0.05);the balloon placed to the active period of time and delivery time showed no significant difference between the two groups( t=0.09,0.14,both P >0.05);there was no significant difference in postpartum hemorrhage between the two groups( t=0.23,P >0.05);cesarean section rate of the observation group was significantly lower than that of the control group(χ^2=4.04,P <0.05);the intrauterine infection,umbilical cord prolapse and neonatal asphyxia rate of showed no significant difference between the two groups(χ^2=0.68,0.32,0.19,all P >0.05).Conclusion Single and double balloon dilatation have a certain role in improving maternal cervical conditions,but compared with double balloon of cervical dilatation,using single balloon for cervical dilatation can significantly improve maternal natural labor rate,reduce the cesarean section rate,and won't increase the incidence rate of adverse reactions,so it has higher effects in the cervical ripening.
