摘要: 本文对头颅超声检测脑血流动力学筛查新生儿缺血缺氧性脑病(HIE)的效果进行了研究。选取新生儿1364例为研究对象,所有新生儿均给予头颅超声检测脑血流动力学,包括大脑中动脉(MCA)的舒张末期峰值流速(VD)、收缩期峰值流速(VS)、阻力指数(RI),以临床诊断为参照,分析MCA的VD、VS、RI对HIE的筛查价值及其关系。结果显示,HIE患儿有50例(3.67%);HIE新生儿的VD低于非HIE新生儿,HIE新生儿的VS、RI高于非HIE新生儿(P<0.05);VD、VS、RI联合筛查HIE的敏感度、特异度、准确度均高于三者单独诊断(P<0.05)。本文证实了头颅超声检测脑血流动力学对HIE的筛查价值良好,且VD、VS、RI联合检测MCA的筛查价值更高。

Abstract: The screening value of cerebral hemodynamics by head ultrasound for the hypoxic ischemic encephalopathy (HIE) is analyzed in this study. 1364 newborns were enrolled. The cerebral hemodynamics of middle cerebral artery (MCA) of all newborns was detected by the head ultrasound, including the end diastolic velocity (VD), peak systolic velocity (VS) and resistance index (RI). With the clinical diagnosis to be control, the screening value of VD, VS, RI of MCA for HIE was analyzed. The result showed that there were 50 newborns (3.67%) suffering from HIE. The VD in the HIE newborns was significantly lower than that in the non-HIE newborns, while the VS and RI in the HIE newborns were significantly higher than those in the non-HIE newborns (P<0.05). The sensitivity, specificity and accuracy of screening with the combination of the VD, VS, RI was significantly higher than single of them (P<0.05). From above results, it can be concluded that the cerebral hemodynamics has the good screening value for the HIE, and the combined detection is superior to a separate one.
