Abstract：Objective To explore the changes of ultrasound parameters of uterine artery and fetal umbilical artery in patients with pregnancy induced hypertension and the outcome of pregnancy.Methods A total of 60 cases of parturients who were admitted to our hospital from January 2019 to January 2020 were selected as the research objects.According to their pregnancy conditions, they were divided into the pregnancy hypertension group (30 cases) and the normal pregnancy group (30 cases).Ultrasound examination of uterine artery and fetal umbilical artery was used in the two groups.The pregnancy outcome of the two groups was compared.Results The results of uterine artery blood flow parameters such as arterial pulsatility index (PI), systolic blood pressure maximum blood flow velocity/end diastolic blood flow velocity (S/D) in the pregnancy hypertension group were higher than those in the normal pregnancy group (P＜0.05).The results of PI, S/D and other fetal umbilical artery blood flow parameters in the pregnancy hypertension group were higher than those in the normal pregnancy group (P＜0.05).But there was no significant difference in resistance index(RI) between the two groups (P＞0.05).The incidence rates of fetal distress, neonatal growth restriction, neonatal asphyxia, cesarean section and premature delivery in the pregnancy hypertension group were higher than those in the normal pregnant group, and the neonatal weight and Apgar score in the pregnancy hypertension group was lower than that in the normal pregnancy group (P＜0.05).Conclusion Compared with the healthy pregnant women, the uterine artery blood perfusion of the patients with pregnancy induced hypertension is significantly higher, and the fetal umbilical artery blood flow resistance is higher, which affects the growth and development of the fetus, so the diagnosis and treatment should be strengthened.
