彩色超声多普勒检查预测胎儿宫内缺氧

Predicting Fetal Intrauterine Hypoxia by Examination of Clour Doppler Ultrasonography

目的 运用彩色多普勒超声监测胎儿脐动脉血流动力学指标 ,预测宫内缺氧的临床价值。方法 应用彩色多普勒超声检测 12 8例孕妇胎儿脐动脉血流动力学指标 ,并进行相关分析。结果 胎儿的脐动脉 (UMA)S/D值>3、PI值 >1 7、RI值 >0 8时 ,提示宫内缺氧。高危组缺氧发生率与正常组缺氧发生率比较差异有显著性 (P <0 0 0 1)。结论 产前直接监测胎儿脐血流动力学指标 ,可以预测胎儿宫内缺氧 ,及早发现异常 ,及时治疗 ,对于降低围产儿死亡率具有临床实用价值。

Objective To evaluate the clinic value of predicting fetal intrauterine hypoxia by measuring fatal blood flow velocity kinetic indices of fetal umbilical artery (UmA) with clour Doppler ultrasonography.Methods UmA kinetic indices of 128 fetal mothers were examined with clour Doppler ultrasonography and their correlation analysis was made.Results When the S/D value of UmA was more than 3,PI more than 1.7,and RI more than 0.8,fetal intrauterine hypoxia was suggested.There were significant differences between the hypoxia incidences of the high risk group and the normal (P<0.001).Conclusion The anteratal direct monitoring of blood flow velocity kinetic indices of fetal UmA can predict fetal intrauterine hypoxia,find abnormal conditions early and treat them promptly,and has a clinic practicaal value in decreasing the perinatal mortality.
