为预测胎儿宫内缺氧 ,应用彩色多普勒超声仪对 15 0例孕妇的胎儿进行血流测定。结果 :胎儿大脑中动脉 (MCA)血流 S/ D<4、PI<1.4、RI<0 .6 ;脐动脉 (UMA)血流 S/ D>3、PI>1.7、RI>0 .8、PI RI MCA/ PI RIUMA<1时 ,提示胎儿宫内缺氧 ;高危妊娠组胎儿缺氧发生率与正常组比较有明显差异性 (P<0 .0 0 1) ;两组围产儿不良结局 ,如低体重儿、胎儿窘迫、新生儿窒息、围产儿死亡率均有显著差异。产前监测胎儿大脑中动脉、脐动脉血流指标 ,可以了解胎儿颅脑循环及胎儿胎盘循环状态 ,预测胎儿宫内缺氧
To predict intrauterine hypoxia, color Doppler ultrasound was used to measure the blood flow of fetus in 150 pregnant women. Results: The blood flow of fetal middle cerebral artery (MCA) was S / D <4, PI <1.4, RI <0.6. The blood flow of umbilical artery was S / D> 3, PI> 1.7, RI> PI RI MCA / PI RIUMA <1, prompted intrauterine hypoxia; high risk pregnancy group fetal hypoxia incidence compared with the normal group there was significant difference (P <0 01); two groups of adverse outcomes of perinatal children, Such as low birth weight children, fetal distress, neonatal asphyxia, perinatal mortality rates were significantly different. Prenatal monitoring fetal artery in the middle cerebral artery, umbilical artery blood flow indicators, can understand the fetal brain circulation and fetal placental circulation state, predict intrauterine hypoxia
