      [Abstract] Objective To explore the clinical value of Doppler ultrasound monitoring of uterine artery blood flow during pregnancy in high-risk pregnancy. Methods A total of 58 high-risk pregnancy patients admitted to the hospital from July 2016 to October 2018 were selected, and 58 normal pregnant women were included in the study during the same period. They were all given multiple uterine artery Doppler ultrasound monitoring in the early, middle and late pregnancy. Compare the ultrasonic monitoring parameter values of the two groups of patients, observe and record the occurrence of early end-diastolic notches in the two groups and the normal and abnormal ratios of S/D in all patients; compare the early, mid and late uterine artery Doppler ultrasound monitoring values in the test group Whether there is predictive value for high-risk pregnancy. Results The uterine artery blood flow S/D ratio, RI and PI parameter values of the experimental group were higher than those of the control group,the difference was statistically significant(P<0.05). The occurrence of early end-diastolic notches in the experimental group was 46.5%, and the occurrence of early end-diastolic notches in the control group was 6.9%, the difference was statistically significant(χ2=23.288, P<0.05). In all patients, the normal S/D ratio was 67.2%, and the abnormal S/D ratio was 32.8%. The adverse maternal and infant outcome of the test group with early diastolic notch was higher than that of the test group without early diastolic notch,the difference was statistically significant(P<0.05). The adverse maternal and infant outcome of patients with normal S/D was lower than those with abnormal S/D ratio,the difference was statistically significant(P<0.05). The weight of newborns with early diastolic notch in the experimental group was lower than that of patients without early diastolic notch,the difference was statistically significant(P<0.05), and the weight of newborns with normal S/D ratio was higher than that of patients with abnormal S/D ratio,the difference was statistically significant(P<0.05). Conclusion The changes in various parameters of uterine artery Doppler ultrasound monitoring in the early, middle and late pregnancy have obvious predictive value for high-risk pregnancy. Among them, S/D ratio and early diastolic notch have important clinical significance in high-risk pregnancy.
