【摘要】：死胎是指妊娠大于23+6周、无生命迹象的胎儿,是围产儿死亡的主要原因之一,产前有效预测死胎,对降低围产儿死亡率具有重大意义。利用彩色多普勒超声监测不同孕期母体子宫动脉血流参数,特别是妊娠中期子宫动脉搏动指数(PI)对与子痫前期、胎盘早剥、小于胎龄儿(SGA)相关的死胎预测有重要意义;监测胎儿各项多普勒血流参数,如脐动脉、大脑中动脉、静脉导管、腹内脐静脉等,能够反映胎儿宫内缺氧状况,提高胎儿窘迫的诊断率;联合监测母体及胎儿各项血流参数,全面评估胎儿宫内缺氧程度并及时干预,可避免死胎的发生。
[Abstract]:Stillbirth is one of the main causes of perinatal death, which is more than 236 weeks gestation and has no sign of life. Prenatal effective prediction of stillbirth is one of the main causes of perinatal death. It is of great significance to reduce perinatal mortality. Using color Doppler ultrasound to monitor maternal uterine artery blood flow parameters, especially the uterine artery pulsatile index (PII) in the second trimester of pregnancy and pre-eclampsia. Placental abruption, smaller than gestational age (SGA) is of great significance in prediction of stillbirth. Monitoring fetal Doppler blood flow parameters, such as umbilical artery, middle cerebral artery, venous catheter, intraabdominal umbilical vein and so on, can reflect fetal intrauterine hypoxia and improve the diagnosis rate of fetal distress. Combined monitoring of maternal and fetal blood flow parameters, comprehensive evaluation of fetal intrauterine hypoxia and timely intervention can avoid the occurrence of stillbirth.
