目的：预测胎儿宫内缺氧。方法：应用彩色多普勒超声对147例孕妇进行详细观察。结果：胎儿的大脑中动脉（MCA）血流S／D值＜4、PI＜1.4、RI值＜0.6（S／D、PI、RI值简称阻力指标）；脐动脉（UMA）血流S／D值＞3、PI值＞1.7、RI值＞0.8；PI、RIMCA／PI、RIUMA＜1时，提示胎儿宫内缺氧.妊高征组和伴IUGR的妊高征组缺氧发生率与正常组缺氧发生率比较差异有显著性（P＜0.001）。结论：产前直接监测胎儿脑、脐血流阻力指标，可以了解胎儿颅脑血循环及胎儿胎盘循环状态，预测胎儿宫内缺氧。
Objective: To predict fetal hypoxia. Methods: 147 cases of pregnant women were observed in detail by color Doppler ultrasound. Results: The blood flow of fetal middle cerebral artery (MCA) S / D <4, PI <1.4, RI value <0.6 (S / D, PI, RI value referred to as resistance index); umbilical artery (UMA) D value> 3, PI value> 1.7, RI value> 0.8; PI, RIMCA / PI, RIUMA <1, suggesting fetal hypoxia. PIH group and PIH with IUGR group, the incidence of hypoxia and The incidence of hypoxia in the normal group was significantly different (P <0.001). Conclusion: Prenatal direct monitoring of fetal brain, umbilical blood flow resistance index can understand fetal brain blood circulation and fetal placental circulation status, predict fetal hypoxia.
