1495例早产儿早产原因及预后临床分析

The Analysis of Cause and Prognosis in 1495 Case with Premature Infants

目的探讨不同胎龄早产儿早产原因、并发症及近期预后。方法对2007年1月至2008年6月在我院出生的1495例存活早产儿进行回顾性分析，按不同孕周分为35～37周组、32～35周组以及〈32周组，对3组早产儿的早产原因，合并症以及近期预后进行分析。结果胎膜早破是引起早产最主要的原因，其他依次为妊娠期高血压疾病、多胎、胎盘因素及胎儿宫内窘迫。胎龄〈32周组出现各种合并症的概率〉35～37周组和32～35周组，差异有统计学意义。近期预后〈32周组正常出院率为78%，低于另2组，差异有统计学意义。结论产科、儿科医师应当掌握引起早产的原因，积极防治早产高危因素，提高早产儿的救治水平。

Objective To discuss the causes of premature, the incidence of complications and shortterm prognosis in different gestational age of preterm premature infants. Methods The 1495 case of sur- vival of premature infants born in our hospital＇ s January 2007 to June 2008 were divided into three groups. Which are 35 -37week group,32 -35week group,as well as 〈 32week groups. We analyzed the causes of premature infants the incidence of complications, as well as short-term prognosis for analysis. Results Premature rupture of membranes is the main reason causing premature, followed by other hypertensive disorders in pregnancy, multiple births, placental factors and fetal distresses. And a variety of complications in less than 32 weeks gestational age were greater than the probability of other two groups, the differences were significant. Short-term prognosises on normal discharge rate in less than 32 weeks group were 78 percent, lower than the other two groups. Conclusion Obstetricians and neonatal physicians should grap the causes of premature birth, active prevent and control of the risk factors for premature birth and try our best to improve the rate of survival and the quality of life.
