未足月胎膜早破患者易发因素及妊娠结局探讨

目的：探讨未足月胎膜早破（PPROM）的易发因素和妊娠结局。方法入选我院2008年1月-2012年12月PPROM孕妇180例，统计分析易发因素和妊娠结局。结果多元逐步回归分析发现，与PPROM显著相关的易发因素有：双胎，人流史≥2次和臀位，差异有统计学意义（P 〈0.05）；所有分娩方式中，剖宫产率最高，差异有统计学意义（P 〈0.05）；新生儿死亡率为5.0%（3/60）。结论 PPROM的易发因素包括双胎、人流史≥2次和臀位，应尽量避免上述因素，以提高顺产率和降低新生儿死亡率。

Study on inducing factors and pregnancy outcome in patients with preterm premature rupture of the membrane

Objective To investigate inducing factors and pregnancy outcome in patients with preterm premature rupture of the membrane（PPROM）. Methods 180 pregnant women with PPROM from January 2008 to December 2012 in our hospital were selected, statistical analyzed PPROM risk factors and pregnancy outcome. Results By multiple stepwise regression analysis, PPROM was associated with the susceptibility factors： twin pregnancy, induced abortion history≥2 and breech presentation, the difference were statistically significant（P 〈0.05）; all the mode of delivery, cesarean section rate was the highest, the difference was statistically significant（P 〈0.05）; neonatal mortality rate was 5.0%（3/60）. Conclusion The risk factors of PPROM include twin pregnancy, induced abortion history ≥2 and breech, should try to avoid the above factors to increase the rate of vaginal delivery and reduce the neonatal mortality rate.
