268例早产临床分析

A clinical analysis on 268 cases with premature birth

目的探讨早产的相关因素及高危因素。方法回顾性分析268例早产产妇(早产组)临床资料,并随机抽样等量足月产妇资料(对照组),比较两组孕产史、产前检查以及孕妇的产科合并症等危险因素。结果早产组有人工流产史者124例(46.2%),人工流产≥2次者60例(22.4%),均明显多于对照组的99例(36.9%)和30例(11.2%)(P<0.05)。早产组规则产前检查者148例(55.2%),明显低于对照组的196例(73.1%)(P<0.05)。胎膜早破、子痫前期、多胎、胎位不正等为导致早产的高危因素。结论早产是多因素作用的结果;应注重产前检查,加强围生期保健,降低早产的发生率。

Objective To investigate the factors and high risk factors for premature birth. Methods Data of 268 patients（group A） with premature birth were analyzed. Another 268 fullterm parturients（group B） in the same period were randomly selected as the controls. The risk factors such as gestation and birth, antenatal care and complications of pregnancy were compared between two groups. Results The number of induced abortion and without regular routine prenatal tests were the premature birth-related factors. There were 124 cases（46. 2~） with a histry of induced abortion, of whom 60 cases（22. 4~） underwent induced abortion for ≥ twice in group A. There were 99 eases （36.9%） with a histry of induced abortion, of whom 30 cases（11.2%） underwent induced abortion for ≥ twice in group B. The differences were significant between two groups（P〈0. 05）. The high risk factors for premature birth were preterm premature rupture of membrane, preeclampsia, multiple pregnancy and abnormal position of fetus. Conclusion Premature birth is caused by many factors. Attention should be paid to the prepartal examination and perinatal care for reducing the rate of premature birth.
