摘　　要：目的探讨分析腹部超声检测子宫动脉血流参数对胎儿生长受限及先兆流产的预测价值。方法选择2022年1月至2023年12月在开封市第二中医院接收的30例胎儿生长受限孕妇、30例先兆流产孕妇及30例正常妊娠孕妇进行对照研究,分别纳入胎儿生长受限组、先兆流产组及对照组,所有孕妇均接受腹部超声检查,测量子宫动脉血流参数,分析各参数预测胎儿生长受限、先兆流产的价值。结果与对照组子宫动脉血流参数相比,胎儿生长受限组收缩期峰值/舒张末期流速(S/D)、搏动指数(PI)、阻力指数(RI)明显更高(P<0.05);与对照组子宫动脉血流参数相比,先兆流产组S/D、PI、RI明显更高(P<0.05);S/D、PI、RI预测胎儿生长受限的灵敏度为81.62%、86.34%、82.00%,特异度为85.73%、91.50%、93.48%;S/D、PI、RI预测先兆流产的灵敏度为85.79%、84.60%、78.63%,特异度为87.92%、88.65%、85.30%。结论胎儿生长受限、先兆流产孕妇的子宫动脉血流参数与正常妊娠孕妇存在明显差异,腹部超声监测子宫动脉血流参数预测胎儿生长受限、先兆流产的效能较高,值得推广。【Objective】To explore and analyze the predictive value of abdominal ultrasound detection of uterine artery blood flow parameters for fetal growth restriction and threatened miscarriage.【Methods】From February 2022 to December 2023,30 pregnant women with fetal growth restriction,30 pregnant women with threatened miscarriage,and 30 pregnant women with normal pregnancy who were admitted to Kaifeng Second Traditional Chinese Medicine Hospital were selected for a control study.They were respectively included in the fetal growth restriction group,threatened miscarriage group,and control group.All pregnant women underwent abdominal ultrasound examination to measure uterine artery blood flow parameters and analyze the value of each parameter in predicting fetal growth restriction and threatened miscarriage.【Results】Compared with the control group,the fetal growth restriction group had significantly higher peak systolic/diastolic flow velocity(S/D),pulsatile index(PI),and resistance index(RI)in the uterine artery blood flow parameters(P<0.05).Compared with the control group,the S/D,PI,and RI of the threatened abortion group were significantly higher(P<0.05).The sensitivity of S/D,PI,and RI in predicting fetal growth restriction was 81.62%,86.34%,and 82.00%,with specificity of 85.73%,91.50%,and 93.48%.The sensitivity of S/D,PI,and RI in predicting threatened miscarriage was 85.79%,84.60%,and 78.63%,while the specificity was 87.92%,88.65%,and 85.30%.【Conclusion】There are significant differences in uterine artery blood flow parameters between pregnant women with fetal growth restriction or threatened miscarriage and normal pregnant women.Abdominal ultrasound monitoring of uterine artery blood flow parameters has a high efficiency in predicting fetal growth restriction and threatened miscarriage,and is worth promoting.
