摘要
为了解新生儿缺氧缺血性脑病(HIE)的脑电图(EEG)特点及评价EEG对HIE的诊断价值,对57例HIE进行了EEG检查分析,并与头颅CT检查结果进行比较。结果:57例HIE患儿的EEG异常率为84.2%(48/57);其中EEG轻度异常为64.6%(31/48),重度为35.4%(17/48),伴有惊厥性放电者占25.0%(12/48)。EEG异常率轻度HIE为73.3%(22/30),中度HIE为95.2%(20/21),重度HIE的EEG全部为重度异常(100%),说明HIE程度越重,EEG异常率越高。轻度HIE的EEG以背景活动紊乱为主,中重度HIE的EEG表现为背景活动抑制及惊厥性放电。HIE的患儿EEG与头脑CT比较,差异无显著意义,但无创伤、经济、敏感。提示:EEG不仅对新生儿HIE的诊断及预后的评价具有重要意义,而且对各种原因引起的新生儿中枢神经系统功能紊乱的诊断也具有重要价值。
We analysed and compared electroencephalogram (EEG) findings of 57 neonatal hypoxic ischemic encephalopathy (HIE) to the results of CT scan to observe the EEG features of neonatal HIE and to evaluate its diagnostic value. The EEG abnormality rate in the cases of HIE was 84.2%, of whom the EEG was slightly abnormal in 64.6% and severely abnormal in 35.4%, and 25.0% of them had seizure discharges. The EEG abnormality rates of mild, moderate and severe HIE were 73.3%, 95.2% and 100%, respectively. The results indicate that EEG abnormality rate varies with the severity of HIE. EEG findings of mild HIE were charicterized by the irregularity of background activity, whereas those of moderate and severe HIE by the suppression of background activity and seizure discharges. The non invasive, inexpensive and sensitive features of EEG suggest that it should be considered as a valuable approach to HIE monitoring.
