应用多谱勒超声预测胎儿宫内窘迫的临床意义

The clinical value of Doppler ultrasound for the Predication of Fetus Hypoxia

目的:探讨晚孕期联合检测胎儿大脑中动脉(MCA)与子宫螺旋动脉(UtSA)的血流参数预测胎儿宫内窘迫的临床意义。方法:应用彩色多普勒超声检测100例正常妊娠和36例宫内窘迫胎儿MCA、UtSA阻力指数(RI)、搏动指数(PI)及S/D值,计算UtSA与MCA各指标比值。结果:窘迫组胎儿UtSA-PI、UtSA-RI、UtSA-S/D测值均高于正常组(P<0.01),MCA-PI、MCA-RI、MCA-S/D测值均低于正常组(P<0.05),UtSA与MCA血流参数的比值均高于正常组(P<0.01)。结论:联合检测大脑中动脉与子宫螺旋动脉可以预测胎儿宫内缺氧。

Objective： To study the clinical value of combined detect MCA and UtSA Doppler parameters for the predication of fetus hypoxia.Methods： Color Doppler was used to examine fetal MCA and UtSA blood flow waveforms in two groups：normal pregnancy （100 cases）and pregnancy with fetal distress （36 cases）.The resistant index （RI）,Pulsatility index （PI）, and peak systolic to end diastolic ratio （S/D）were evaluated and the resistant parameter ratios of MCA to UtSA were calculated and analysed.Results ：In high risk group,UtSA-PI,UtSA-RI and UtSA-S/D were all higher than that in control group（all P〈0.01）, MCA-PI is lower than that in control group （all P〈0.05）, and the ratio of UtSA to MCA was higher than that in control group （all P〈0.01）. Conclusion：The ratio of UtSA to MCA could predict fetus hypoxia.
