Objective: To discuss the value of electroencephalogram (EEG) in diagnosis, judging serious degree and prognosis of children with acute viral encephalitis. Methods: 60 patients were diagnosed with viral encephalitis were given EEG, head CT, CSF examination and the results were analyzed retrospectively. Results: Abnormal EEG rate was 86.7%, CT abnormal rate was 25.0%, abnormal cerebrospinal fluid rate was 58.3%, with paired χ2 test, the difference was statistically different (P<0.05), the severity of EEG and the severity of the patient's condition and prognosis were parallel. Conclusion: EEG is simple, with no trauma and side effects , and it has a good value in early diagnosis, judging the severity, assessing the efficacy and prognosis of viral encephalitis in children.%目的:讨论脑电图对小儿急性病毒性脑炎的诊断价值、判断病情严重程度及对疾病预后评价的意义.方法:对60例确诊病毒性脑炎病例行脑电图、头颅CT、脑脊液检查,并对结果行回顾性分析.结果:脑电图异常率为86.7%,头颅CT异常率为25.0%,脑脊液异常率为58.3%,采用配对χ2检验,差异有统计学意义(P<0.05),且脑电图的严重程度和患者的病情轻重和预后呈平行关系.结论:脑电图检查简便易行,没有创伤及副作用,在小儿病毒性脑炎的早期诊断、判断病情严重程度、评估疗效及预后等方面有很好的应用价值.
