The peak systolic velocity/end diastolic velocity (S/D), pulse index (PI) and resistance index (RI) of cord blood were measured by ultrasound. According to the S/D, 109 cases were divided into 62 cases in the control group (S/D 0.05). ROC curve analysis showed that cord blood flow RI of pregnant women with gestational hypertension had the highest sensitivity and AUC in predicting intrauterine fetal hypoxia and growth restriction, and PI had the highest specificity in predicting intrauterine fetal growth restriction. The specificity of S/D, PI and RI in predicting intrauterine hypoxia was consistent (all 80%).Conclusion: The different parameters of umbilical blood flow in hypertensive pregnant women during pregnancy provide a good assessment of intrauterine fetal condition and can be used as clinical indicators to predict poor prognosis of intrauterine fetal hypoxia and fetal growth restriction.Keywords: gestational hypertension, hypoxia, growth restriction, umbilical blood flow, assessment
