运用彩色多普勒监测正常妊娠、妊高征、妊高征合并ＩＵＧＲ３组胎儿腹主动脉血流的Ｓ／Ｄ值、ＰＩ值、ＲＩ值。结果表明，妊高征组（合并或不合并ＩＵＧＲ）胎儿腹主动脉血流Ｓ／Ｄ值大于４、ＰＩ值大于１．８、ＲＩ值大于０．８时，围产儿结局异常占５０％。当血流阻力指标异常升高时，应考虑有ＩＵＧＲ或胎儿窘迫发生。当异常波形出现时，表明血流阻力指标升高，血流量减少，胎儿缺氧严重，宫内状况差，新生儿预后不良的发生率高。此监测方法可及早发现胎儿异常，及时处理以降低围产儿病死率。
Color Doppler was used to monitor S / D, PI and RI of fetal abdominal aorta blood flow in normal pregnancy, PIH and PIH. The results showed that fetus abdominal aorta blood flow S / D value greater than 4 and PI value greater than 1.8 in PIH group (with or without IUGR), and abnormal perinatal outcome was 50% when RI value was greater than 0.8. When the flow resistance index abnormal increase, should consider IUGR or fetal distress occurs. When the abnormal waveform appears, indicating increased blood flow resistance index, decreased blood flow, fetal hypoxia, poor intrauterine conditions, poor prognosis of neonatal high incidence. This monitoring method can be early detection of fetal abnormalities, timely treatment to reduce perinatal mortality.
