目的探讨脑电图(EEG)对儿童病毒性脑炎早期诊断及预后评估的临床价值。方法对368例临床诊断为病毒性脑炎的患儿进行EEG描记,并在临床症状消失后追踪其脑电活动恢复情况。结果 368例患儿经治疗后,入院到临床症状消失需3~5 d 297例,6~8 d 71例;EEG恢复正常需5~7 d 224例,8~14 d 94例,15 d~半年6例,半年以上2例,另外3例EEG未恢复正常,1例遗留轻度异常,2例处于临界状态。结论 EEG对儿童病毒性脑炎早期诊断及预后评估有较高的临床价值。
Objective To investigate the clinical value of EEG in the early diagnosis and prognosis of viral encephalitis in children. Methods EEG was performed on 368 children with viral encephalitis, and the recovery of EEG activity was tracked after the clinical symptoms disappeared. Results After treatment, 368 children were admitted to the hospital for 3 to 5 days, 297 cases disappeared, 71 cases were 6 to 8 days, 224 cases were required for recovery from 5 to 7 days, 94 cases were 8 to 14 days, Six cases in six months, two cases more than half a year, the other three cases did not return to normal EEG, 1 case left mild abnormalities, 2 cases in a critical state. Conclusion EEG has high clinical value in the early diagnosis and prognosis evaluation of viral encephalitis in children.
