早产危险因素261例分析

An analysis of risk factors in 261 preterm delivery

目的探讨早产发生的危险因素和对围生期的影响。方法对我院261例早产孕妇(早产组)与同期随机抽取的261足月孕妇(对照组)进行回顾性比较,分析早产的危险因素及对围产期的影响。结果高龄与未定期产检是早产的相关危险因素。早产的病因中胎膜早破、子痫前期、产前出血、妊娠合并症均多于对照组,两组差异有统计学意义。早产使剖宫产率、新生儿窒息、低体重儿增加。结论定期产前检查、适龄妊娠、提高围产期保健意识可降低早产的发生,提高围生医学质量。

Objective To evaluate the risk factors of preterm delivery and the effects toperinatal period. Methods Ret- rospective analysis was between the preterm delivery group and the control group. 261 preterm delivery cases in our hospital from July 2009 to December 2010 was selected as the preterm delivery group, 261 term delivery cases was produced randomly in the same period and the same hospital as the control group. The risk factors of preterm delivery and the effects to perinatal period was analysised. Results Old age in pregnant woman and irregular obstetrical examination are the correlative factors of preterm deliv- ery. Premature rupture of membrances, preeclampsia, antepartum hemorrhage, pregnancy complications of the preterm delivery causes were more than those of the control group. There was statistical significance （ P 〈 0. 05 ）. Preterm delivery could increase neonatal asphyxia, perinatal mortality, low birth weight. Conclusion Regular obstetrical examination , right age in pregnant women and improving perinatal healthcare can decrease premature birth, and improve perinatal quality.
