目的探讨脐动脉、大脑中动脉、静脉导管预测高危胎儿结局的临床价值。方法选取我院门诊81例高危孕妇,依据新生儿不同出生结局分为正常组、轻度异常组、严重异常组,比较脐动脉、大脑中动脉、静脉导管血流参数的变化。结果动静脉血流参数与严重不良出生结局具有密切相关性,其中DV-PVIV最大,依次为AEDF、DV-S/A。它们的值越大,出生结局越差。结论动静脉血流参数与严重不良出生结局具有密切相关性,其中DV-PVIV、AEDF相关性较高。
Objective To investigate the clinical value of umbilical artery, middle cerebral artery and venous catheter in predicting high-risk fetus outcome. Methods Eighty-one high-risk pregnant women in our hospital were selected and divided into normal group, mild abnormal group and severe abnormal group according to their different neonatal outcomes. The changes of blood flow parameters in umbilical artery, middle cerebral artery and venous catheter were compared. Results The parameters of arteriovenous flow were closely related to the outcome of severe adverse birth. DV-PVIV was the largest, followed by AEDF and DV-S / A. The greater their value, the worse their birth outcomes. Conclusions Arterial and venous blood flow parameters are closely related to the outcome of severe adverse births, of which DV-PVIV and AEDF are highly correlated.
