子宫动脉超声在妊娠期高血压病的应用价值

The Application Value of Uterine Artery Ultrasound in Hypertension during Pregnancy

目的探究子宫动脉超声技术在妊娠期高血压病的临床效果和应用价值。方法随机选取2017年2月—2020年1月于该院就医治疗的66例晚期妊娠期患有高血压的孕妇与68名正常妊娠期孕妇作为观察对象,其中正常孕妇作为对照组,而患有高血压的晚期妊娠期孕妇为观察组。采用超声多普勒技术对所有134例研究对象进行检测记录,观察比较患有高血压孕妇和正常孕妇的子宫动脉血流动力学状态。在134例孕妇妊娠结束后,对所有观察对象的收缩-舒张流速比值(S/D)、阻力指数(RI)和搏动指数(PI)等多普勒血流监测参数进行处理分析;并对观察组和对照组孕妇的妊娠结果进行比较分析。结果 (1)观察组孕妇的S/D(2.47±0.60)、RI(0.57±0.08)、PI(0.99±0.28)和舒张早期切迹发生率54.55%均显著高于对照组孕妇,差异有统计学意义(t=4.010、6.530、7.470,χ^(2)=25.625,P<0.05)。(2)观察组孕妇的平均孕周数(34.36±4.77)周和新生儿体质量(2 644.81±718.29)g显著低于对照组,差异有统计学意义(t=5.030、6.770,P<0.05),而观察组孕妇的剖宫产率63.64%、早产率24.24%、胎儿窘迫的发生率18.18%和体质量指数(29.47±3.85)kg/m2都显著高于对照组孕妇,差异有统计学意义(χ^(2)=31.554、10.824、6.388,t=9.090,P<0.05)。结论子宫动脉超声技术可以对妊娠期孕妇在高血压围生期的并发症进行预测,具有一定的应用价值。

Objective To explore the clinical effect and application value of uterine artery ultrasound technology in hypertension during pregnancy.Methods 66 pregnant women with hypertension in late pregnancy and 68 pregnant women with normal pregnancy who were treated in the hospital from February 2017 to January 2020 were randomly selected as observation objects.Among them,normal pregnant women served as the control group,and pregnant women in late pregnancy with hypertension were the observation group.Ultrasound Doppler technology was used to test and record all 134 study subjects,to observe and compare the uterine artery hemodynamic status of pregnant women with hypertension and normal pregnant women.After the pregnancy of 134 pregnant women,the Doppler blood flow monitoring parameters such as the systolic-diastolic velocity ratio(S/D),resistance index(RI)and pulsatility index(PI)of all subjects were processed and analyzed.The pregnancy results of pregnant women in the observation group and the control group were compared and analyzed.Results 1.The S/D(2.47±0.60),RI(0.57±0.08),PI(0.99±0.28)and the incidence of early diastolic notch 54.55%in the observation group were significantly higher than those in the control group,the difference was statistically significant(t=4.010,6.530,7.470,χ^(2)=25.625,P<0.05).2.The average gestational weeks of pregnant women in the observation group was(34.36±4.77)weeks and the weight of their newborns was(2644.81±718.29)g were significantly lower than those of the control group,the difference was statistically significant(t=5.030,6.770,P<0.05),while the cesarean section rate of pregnant women in the observation group was 63.64%,the preterm birth rate of 24.24%,the incidence of fetal distress 18.18%and the body mass index of(29.47±3.85)kg/m2 were significantly higher than those of the control group,the difference was statistically significant(χ^(2)=31.554,10.824,6.388,t=9.090,P<0.05).Conclusion Uterine artery ultrasound technology can predict the complications of pregnant women in the perinatal period of hypertension,with certain application value.
