目的：探讨妊高征患者胎儿脐动脉血流速度比值（Ｓ／Ｄ）与围产儿预后的关系。方法：应用彩色超声波对９８例妊高征患者胎儿脐动脉血流速度指数进行测量并与新生儿体重、新生儿 Ａｐｇａｒ评分、羊水性质和围产期结局的关系进行分析。结果：９８例妊高征中有３４例围产儿预后良好，６４例围产儿预后不良。围产儿预后不良发生率，中、重度妊高征明显高于轻度妊高征（Ｐ＜０．０１）。 Ｓ／Ｄ比值与围产儿预后的程度有明显的相关性。结论：产前监测脐动脉血流速度指数可间接了解妊高征患者胎儿宫内情况，及时判定胎儿宫内安危状态及围产期预后的结局。
Objective: To investigate the relationship between fetal umbilical artery blood flow velocity ratio (S / D) and perinatal outcome in patients with pregnancy induced hypertension. Methods: Fetal umbilical artery blood flow velocity index was measured in 98 patients with PIH using color ultrasound. The relationship between neonatal weight, neonatal Apgar score, amniotic fluid properties and perinatal outcome was analyzed. Results: In 98 PIH cases, 34 cases of perinatal children had a good prognosis and 64 cases of perinatal poor prognosis. The poor prognosis of perinatal fetus, moderate and severe pregnancy-induced hypertension was significantly higher than that of mild pregnancy-induced hypertension (P <0.01). S / D ratio and the degree of prognosis of perinatal obvious correlation. Conclusion: Prenatal monitoring of umbilical artery blood flow velocity index can be indirect understanding of intrauterine pregnancy in patients with PIH, timely determination of fetal status and prognosis of perinatal outcome.
