脑电图在新生儿缺氧缺血性脑病的临床意义并与CT结果比较

The elinnieal significance of electroencephalogram of neonatal hypoxic-ischemicencephalophthy and its comparison with the results of CT

目的:探讨脑电图(EEG)在新生儿缺氧缺血性脑病(HIE)中的应用价值。方法:回顾性分析185例HIE患儿临床资料、EEG、CT表现。结果:EEG异常率为75.14%,主要为背景活动的改变,在HIE早期表现明显;CT异常主要表现在HIE的中、重度临床分型上。结论:①EEG可作为判断HIE严重程度的价值指标;②EEG对HIE有早期诊断价值,尤其是亚临床型的HIE优于CT;③EEG的动态监测对HIE预后评估有较大判断价值。

Objective： To discuss the apply value of electroencephalogram in neonatal hypoxic ischemicencephalophthy. Methods： Retrospective analysis of 185 cases of neonatal hypoxic -ischemicencephalophthy including clinical, EEG and CT findings. Results： The EEG abnormality rate in the cases of HIE was 75%. EEG findings of HIE were characterized by the irregularity of background activity, obviously in the early stage of HIE ; the CT abnormality rate in the cases HIE was 72% and EEG findings were obvious in the intermediate and advanced stages of HIE. Conclusion： EEG can be considered as valuable indicator to evaluate the severity of HIE; EEG has early diagnostic value in HIE , especially better diagnostic value than CT in the subclinical type of HIE; EEG＇s dynamic monitoring has greater diagnostic value to evaluate prognosis of HIE.
