[摘要] 目的探究孕期子宮动脉血流多普勒超声监测在高危妊娠中的临床价值。方法便利选取该院于2016年7月—2018年10月收治的58例高危妊娠患者为试验组，同期58名正常孕妇患者列为对照组，均给予孕早、中、晚多次子宫动脉多普勒超声监测。对比两组患者超声监测参数值、观察记录两组患者舒张末早期切迹发生情况与所有患者S/D比值正常、异常比例;比较试验组早、中、晚子宫动脉多普勒超声监测值对高危妊娠有无预测价值。结果试验组子宫动脉血流S/D比值、RI、PI参数值均高于对照组，差异有统计学意义（P<0.05），试验组舒张末早期切迹发生为46.5%，对照组舒张末早期切迹发生为6.9%，差异有统计学意义（χ2=23.288，P<0.05）。所有患者中，S/D比值正常比例值为67.2%，S/D比值异常比例值为32.8%。试验组有舒张早期切迹母婴不良结局高于试验组无舒张早期切迹，差异有统计学意义（P<0.05），S/D正常值患者母婴不良结局低于 S/D比值异常患者，差异有统计学意义（P<0.05），试验组有舒张期早期切迹的新生儿体重低于无舒张期早期切迹患者，差异有统计学意义（P<0.05），S/D比值正常患者新生儿体重高于S/D比值异常患者，差异有统计学意义（P<0.05）。结论孕早、中、晚多次对子宫动脉多普勒超声监测的各项参数变化对高危妊娠有明显的预测价值，其中 S /D 比值及舒张早期切迹在高危妊娠中有重要的临床意义。

[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.
