目的:探讨应用人工破膜对初产妇产程及分娩结局的影响。方法:采用随机抽样与分组的方法,将2007年10月至2008年11月在本院分娩的初产妇分成人工破膜组与自然破膜组,初产妇平均年龄26岁,孕周均为38~42周,胎方位均为头先露,无妊娠合并症,对两组之间的产程及分娩结局情况进行比较。结果:人工破膜组总产程平均为8.76 h,自然破膜组总产程平均为12.78 h,两组之间比较差异具有统计学意义(P<0.05);人工破膜组新生儿窒息发生率为0.6%,明显低于自然破膜组的5.4%,差异具有统计学意义(P<0.05),表明宫口开大3 cm左右行人工破膜,能缩短产程,对新生儿预后极为有利。结论:人工破膜对促进产程进展及降低不良妊娠结局具有重要作用。
Objective: To investigate the effects of artificial rupture of membranes on labor and delivery outcomes of primipara. Methods: By random sampling and grouping method, primipara of childbirth in our hospital from October 2007 to November 2008 were divided into artificial rupture group and spontaneous rupture group. The average age of primipara was 26 years and the gestational age was 38 ~ 42 weeks, the fetal position are the first forerunner, no pregnancy complications, between the two groups of labor and childbirth outcomes were compared. Results: The average duration of labor was 8.76 h in artificial rupture and 12.78 h in spontaneous rupture. The difference was statistically significant (P <0.05). The incidence of neonatal asphyxia in artificial rupture was 0.6%, significantly lower than the natural rupture of the group of 5.4%, the difference was statistically significant (P <0.05), that the cervix open about 3 cm artificial rupture, can shorten the labor process, the prognosis of newborns is extremely beneficial. Conclusion: Artificial rupture plays an important role in promoting the progress of labor and reducing the incidence of adverse pregnancy.
