超声观察晚发型先兆子痫患者子宫动脉血流动力学参数

Ultrasonic observation on hemodynamic parameters of uterine artery of patients with late-onset preeclampsia

目的评价彩色多普勒超声观察晚发型先兆子痫(PE)患者子宫动脉血流动力学参数的应用价值。方法纳入94例晚发型PE孕妇(观察组)和106名足月妊娠健康孕妇(对照组),观察2组孕妇临床资料及子宫动脉血流动力学参数[阻力指数(RI)、搏动指数(PI)及收缩期峰值血流速度与舒张末期流速的比值(S/D)]。结果观察组孕妇年龄、体质量指数(BMI)、早产率、剖宫产率、胎儿生长受限率及子宫动脉RI、PI、S/D和舒张早期切迹出现率均高于对照组(P均<0.05),而娩出新生儿体质量小于对照组(P<0.05);观察组38例、对照组2名存在子宫动脉舒张早期切迹孕妇的子宫动脉PI均>1.2。结论采用超声监测晚发型PE患者子宫动脉血流动力学参数可为临床及时处置提供依据。

Objective To explore the application value of color Doppler ultrasonography for evaluating hemodynamic parameters of uterine artery in patients with late-onset preeclampsia(PE).Methods Ninety-forth pregnant women with late-onset PE(observation group)and 106 healthy pregnant women with full-term pregnancy(control group)were enrolled.Clinical data and hemodynamic parameters of uterine artery(resistivity index[RI],pulsatility index[PI]and the ratio of peak systolic velocity to end diastolic velocity[S/D])were measured or calculated.Results The age,body mass index(BMI),premature delivery rate,cesarean section rate,fetal growth restriction rate,RI,PI,S/D and early diastolic notch of uterine artery in observation group were all higher than those in control group(all P<0.05),while the weight of newborns in observation group was lower than that in control group(P<0.05).PI of uterine artery in 38 cases in observation group and 2 healthy pregnant women in control group with early diastolic notch were all>1.2.Conclusion Color Doppler ultrasonography monitoring hemodynamic parameters of uterine artery of late-onset PE pregnant women could provide basis for timely and effective treatment.
