摘　　要：目的探讨如何降低低出生体重儿的围产死亡率。方法对我院1990-2003年14年<2500克的低出生体重儿每两年为一组,对其发生率、围产期死亡率变化趋势及围产期死亡原因进行了分析。结果显示低出生体重儿的发生率明显上升(P<0.001);围产期死亡率明显下降(P<0.001);新生儿死亡率明显下降(P<O.001)。极低出生体重儿死亡率由428.6‰降至98.2‰(P<0.001)。胎儿死亡原因主要是畸形、母亲妊高征和宫内感染,新生儿死亡原因前3位的是畸形、宫内感染及颅内出血。结论加强产前围产保健,对降低低出生体重儿的发生及其死亡率是非常重要的。Objective To analyze the pefinatal mortality of low birth weight（LBW）infants. Methods The period between 1990 and 2003 was divided into 7 stages by two years interval, and the perinatel morfalty, its reasons and trend of change in low birth weight infants （birth weight 〈 2 500 g）were analyzed. Results The incidence of low birth weight infant was increased significantly stage by stage（ P 〈 0.001） ; the perinatal mortality and neonatal mortality decreased significantly （P 〈 0.001） ; the mortality of very low birth weight（VLBW）infant （birth weight 〈 1 500 g） decreased from 428.6%c to 98.2%e（ P 〈 0.001）. The main reasons of fetaldeath were congenital abnormality, maternal pregnancy hypertension disease and intrauterine infection. The main reasons of neonatal death were congenital abnormality, intrauterine infection and intracranial hemorrhage Conclusion Improving perinatal care, early diagnosis and treatment of maternal complications are important strategy of decreasing mortality of LBW infa-nts.
