Abstract:

The death of a fetus before delivery is called stillbirth in China，which is after 20 weeks of gestation.The incidence of stillbirth directly affects the perinatal mortality，which is a sensitive indicator of medical quality in a region and a country.There are usually some traces before stillbirth occurs.The key to prevent stillbirth and improve the quality of obstetrics is to correctly identify high-risk factors，strengthen the management of pregnancy，and effectively use the means of detection.

Key words: stillbirth, management of pregnancy, risk factor

摘要：

我国界定死胎为妊娠20周后临产前的胎儿死亡称为死胎。死胎发生率的高低直接影响围产儿死亡率，而后者是评估一个国家和地区医疗质量的敏感指标。临床上死胎发生前后常有迹可循。正确识别高危因素，加强孕期管理，有效利用检测手段是预防死胎发生，提高产科质量的关键。
