摘要
目的探讨妊娠晚期死胎发生的相关危险因素,以期减少死胎发生,降低围生儿死亡率,提高围生医疗质量。方法回顾性分析2005年1月至2007年6月在本院住院分娩的9733例孕妇中,发生妊娠晚期死胎的孕妇。结果9733例住院分娩孕妇中,发生妊娠晚期(≥28孕周)死胎170例,死胎发生率为17.47‰(170/9733)。剔除因胎儿畸形所致死胎后,校正后死胎发生率为12.24‰(118/9733)。发生妊娠晚期死胎孕妇中16.47%(28/170)年龄≥35岁,64.12%(109/170)孕妇职业为农民及待业者,42.94%(73/170)孕妇孕期未进行产前检查或仅行不定期产前检查,35.88%(61/170)孕妇在死胎发生前自觉胎动异常。妊娠晚期死胎发生原因中,母体因素占第1位,发生率为70.59%(120/170),依次为合并妊娠期高血压疾病(30/170,17.65%)、妊娠期肝内胆汁淤积症(18/170,10.59%)、胎膜早破(17/170,10.00%)、妊娠期糖尿病(16/170,9.41%)、梅毒(2.94%);其余因素依次为胎儿因素(88/170,51.76%)、脐带因素(35/170,20.59%)、胎盘因素(23/17,13.53%)。结论加强围生期宣教及孕期保健,提高孕妇保健意识,积极治疗母体合并症及并发症,可有效降低妊娠晚期死胎发生率,提高围生医疗质量。
Objective To study the relative risk factors of fetal death in the third trimester. Methods Between January 2005 to June 2007, fetal death in the third trimester among 9733 pregnant women who delivered in West China Second University Hospital, Sichuan University were analyzed retrospectively. Results Among 9733 deliveries, 170 cases （17.47%） had fetal death during third trimester（pregnant week ≥28 weeks）. Except for the cases of fetal congenital malformation, the correct fetal death incidence was 12. 14% （118/9733）. Among 170 cases with fetal death, 16.47%（28/170） were at or over 35 years oid, 64. 12% were in low socioeconomic status, 42.94%（73/170） had no or irregular prenatal care, and 35.88% felt abnormal fetal movement before fetal death occurred. Maternal factor （70.59%,120/170） was the most important factor among causes of fetal death. The maternal complications were hypertensive disorders in pregnancy（ 30/170, 17.65%）, intrahepatic cholestasis of pregnancy（ 18/170, 10.59%）, premature rupture of membrane（17/170, 10.00%）, gestational diabetes mellitus（16/170, 9.41%）, and syphilis（2. 94%） in turn. The other factors were fetal factors（88/170, 51.76%）, cord factors（35/170, 20.59%） and placenta factors（23/17, 13. 53%） in turn. Conclusion It is suggested that to intensify the surveillance by both doctors and pregnant women during the pregnancy and to deal with maternal and fetal complications in time which would reduce the fetal death incidence in the late pregnancy and improve the prenatal mortality.
