双球囊引产时阴道球囊位置对引产结局的影响

目的:探讨双球囊引产时阴道球囊位于宫颈口外和宫颈口内对引产结局的影响。方法:选取在河南省人民医院产科引产的60例足月初产妇,随机将阴道球囊置于产妇宫颈口内(A组,30例)和宫颈口外(B组,30例),比较2组产妇的引产效果及母婴结局。结果:取出水囊后,A组的宫颈Bishop评分、宫颈管展平率、宫口扩张率、24 h内阴道分娩率高于B组,差异有统计学意义(均P<0.05)。A组第一产程时间和总产程时间均短于B组,差异有统计学意义(均P<0.05)。2组的剖宫产率、新生儿体质量、孕妇留置水囊疼痛评分及新生儿窒息率比较,差异均无统计学意义(P>0.05)。结论:子宫颈双球囊引产时,将阴道球囊置入宫颈口内能够缩短第一产程和总产程。

Investigation the Effects of Inducing Labor by Different Positions of Vaginal Balloon with Cervical Dilatation Double-Balloon

Objective：To investigate the effects of inducing labor by different position of vaginal balloon with cervical dilatation double-balloon. Methods: Sixty full-term primiparous woman who delivered in department of obstetrics of Henan People′s Hospital were selected as the observation objects. 30 patients of observation group were induced with vaginal balloon inside the cervix（group A）, and the other 30 patients were induced by outside the cervix（group B）randomly. Then the induced outcome and the fetal outcomes of the two groups were compared. Results: The cervical Bishop scores，the cervical flatness，cervical opening rate and the 24-hour birth rate of group A were higher than group B，and the differences were statistically significant （all P＜0.05）. The first labor time and the total delivery process of group A were shorter than group B, the differences were statistically significant （both P＜0.05）. There was no significant difference in cesarean section rate, newborn weight, discomfort score and neonatal asphyxia rate（P＞0.05）. Conclusions: When induced with cervical dilatation double-balloon, placing the vaginal balloon inside the cervix can shorten the first and total delivery process.
