胎龄和出生体重对早产儿预后影响分析

目的:探讨胎龄及出生体重对早产儿预后的影响。方法:回顾性分析无锡市妇幼保健院2008年1月~2009年12月间分娩的217例早产儿资料。结果:早产儿并发症的发生率和死亡率分别为43.8%和2.3%。早产儿并发症和死亡主要发生于胎龄<32周或出生体重<1 500 g的极低体重儿。缺氧缺血性脑病、窒息、呼吸窘迫综合症发生率和死亡率随胎龄或出生体重增加均呈下降趋势。结论:出生前加强孕期保健,尽可能延长胎龄,促进肺成熟;出生后防止早产儿窒息和加强低出生体重儿监护,将降低早产儿并发症发生率和死亡率。

Analysis on effects of fetal age and birth weight on prognosis of premature infants

Objective:To explore the effects of fetal age and birth weight on prognosis of premature infants.Methods:The clinical data of 217 premature infants born in the hospital from January 2008 to December 2009 were analyzed retrospectively.Results:The incidence of complication and mortality of premature infants were 43.8% and 2.3%,respectively;the premature infants less than 32 gestational weeks or birth weight<1 500 g had high incidence of complication and high mortality;the incidences of complications(including hypoxic-ischemic encephalopathy,asphyxia and respiratory distress syndrome) and mortality of premature infants showed a decreasing trend with fetal age and the increase of birth weight.Conclusion:Enhancing pregnant health care before delivery,prolonging fetal age as far as possible,promoting fetal lung maturity,preventing neonatal asphyxia and strengthening the monitoring on low birth weight infants may reduce the incidence of complication and mortality of premature infants.
