多普勒超声检测妊高征胎儿脐动脉及大脑中动脉血流

目的 研究妊高征胎儿血液动力学变化规律,探讨预测胎儿宫内缺氧的临床价值。方法 对正常胎儿和妊高征儿应用彩色多普勒检测脐动脉、大脑中动脉血流并进行相关分析。结果 妊高征胎儿脐动脉血流阻力指标不同程度增高;大脑中动脉血流阻力指标不同程度降低;出生后Apgar分值不同程度降低,以上增高和降低幅度均与妊高征程度有关,即轻度低于中度,中度低于重度。结论 妊高征胎儿血流动力学指标有明显改变,产前多普勒超声检测对预测胎儿宫内缺氧,及时预防和治疗胎儿宫内窘迫,具有一定实用价值。

Doppler Ultrasonography Used for Checking PIH Fetal Umbiliacl Artery and Cerebri Media Artery

Objective To study the law of the pregnancy-induced hypertension syndrome(PIH) fetal bloodstream's dynamic change and inquire the clinical value of predicting fetal intrauterine hypoxia.Methods Using collor Doppler ultrasonograph to check the bloodstream of the normal and the PIH fetal umbilical artery and cerebri media artery,and then analyse it.Results The index of the PIH fetal umbilical arterial bloodstream's asistance increases more or less.The index of the cerebri media arterial bloodstream's resistance reduces more or less. The postpartum infant Apgar score recuces more or less.The extent of the increase or reduce relates to the PIH grade.The low-grade changes less than the moderate-grade.The moderate-grade changes less than the high-grade.Conclusion The PIH fetal blood stream's dynamic index changes obviously.The antenatal exam by Doppler Utrasongraphy is of some practical value to predicting the fetal intrauterine hypoxia and to preventing and curing the fetal intrauterine distress in time.
