死胎病因及管理

死胎的主要原因包括妊娠前母体疾病，如糖尿病，以及妊娠期并发症，如产前出血、妊娠期肝内胆汁淤积症、胎儿生长受限、单绒毛膜双胎、感染等。脐动脉彩色超声多普勒有助于预测死胎病因。小剂量阿司匹林（60～80 mg）有助于预防高危妊娠孕妇发生子痫前期及其他不良围生期结局。死胎尸检、胎盘病理检查和胎母出血检测等是死胎病因检查的基本手段。

The maternal and fetal risk factors and management for stillbirth.

Abstract：The most prominent maternal risk factors for stillbirth are pre-existing maternal disorders such as diabetes, and pregnancy complications such as antepartum haemorrhage,intrahepatic cholestasis of pregnancy，fetal growth restriction, monochorionic twins, and infections.Fetal and umbilical Doppler and ultrasound imaging may predict the causes of stillbirth.The administration of low-dose aspirin (60 80 mg) may prevent preeclampsia and adverse perinatal outcomes in high-risk pregnancy. Autopsy, placental examination, and testing for fetal maternal hemorrhage are basic tests for workup after fetal death.
