探讨儿童脑电图儿童病毒性脑炎的早期诊断和预后评估方面临床研究

Clinical study investigated the EEG of children with viral encephalitis children early diagnosis and prognosis evaluation

目的探讨脑电图在儿童病毒性脑炎的早期诊断和预后评估方面临床研究价值。方法对115例儿童病毒性脑炎患者的脑电图和临床资料进行全面分析研究：97例为脑电图异常,异常率为84.34%。轻度异常51例（44.34%）,中、重度异常46例（40%）。结果治疗2-4周后,脑电图恢复正常81例,未恢复正常11例：轻度异常1例,中度异常6例,4例有明显的意识障碍,1例有经常发作性脑电图异常改变。脑电图异常改变表现为弥漫性慢波,α波节律减弱,或以θ波为主,其中一部分患儿有局限性异常脑电图表现。结论脑电图作为一种检查手段,脑电图异常改变与临床症状、大脑脑实质损伤的严重程度成正向关系,因此脑电图对儿童病毒性脑炎的早期诊断和临床预后评估有着非常重要的正相关性。

Objective To investigate the clinical EEG studies in the early diagnosis and prognosis of children with viral encephalitis aspect value. Methods Of EEG and clinical data of children with viral encephalitis patients a comprehensive analysis of 115cases： 97 cases of abnormal EEG abnormality was 84.34%. Mildly abnormal 51 cases（44.34%）, moderate to severe abnormalities in 46 cases（40%）. Results Of the treatment two weeks- after four weeks, EEG normal 81 cases, 11 cases have not returned to normal： abnormal one case of mild to moderate abnormal six cases, four cases of a clear consciousness, one case had recurrent episodes of EEG abnormalities. Abnormal EEG showed diffuse slow waves, α wave rhythm weakened, or θ wave-based, some of which have limitations in children with abnormal EEG. Conclusion EEG as a screening tool, EEG abnormalities and clinical symptoms, brain parenchymal injury severity positive relationship, so early diagnosis and clinical EEG prognostic assessment of children with viral encephalitis has a very important the positive correlation.
