脑电图在病毒性脑炎病情及预后判断中的意义

目的病毒性脑炎常伴有脑电图的异常,本文探讨脑电图在病毒性脑炎病情判断和预后中的临床意义。方法回顾性选择我院收治的55例病毒性脑炎患者为研究对象,本组55例患者轻症组26例,中症组19例,重症组10例,所有患者均行脑电图监测。观察入院时轻症组、中症组、重症组三组患者脑电图异常及异常程度的分布情况,分析脑电图异常程度与患者病情严重程度及预后情况的关系。结果本组55例患者中,共48例(87.27%)患者脑电图出现异常。轻症组、中症组、重症组三组患者的脑电图异常程度分布比较,差异具有统计学意义(P<0.001),提示脑电图异常明显病情越重。脑电图正常组、轻度异常组、中度异常组及重度异常组患者的预后情况比较,差异具有统计学意义(P<0.001),提示脑电图异常明显预后越差。结论病毒性脑炎患者脑电图检查可作为患者病情判断及预后评估的重要指标。

Significance of Electroencephalogram in Viral Encephalitis Condition and Prognostic Judgment

Objective Viral encephalitis is often accompanied by abnormal electroencephalogram （EEG）. Clinical significance of EEG in viral encephalitis condition judgment and prognosis were explored in this paper. Methods The selective research object of 55 patients with viral encephalitis in our hospital were researched retrospectively, and the 55 cases were divided into mild symptom group with 26 cases, morderate symptom group with 19 cases, severe symptom group with 10 cases, and all cases were performed dynamic monitoring with electroencepha. Among the mild, morderate and severe groups, the abnormality and the distribution of abnormal degree in the EEG were observed and analyzed contrastively, meanwhile, the relationship among abnormal degree in EEG and severity of patients′ conditions and prognosis were analyzed. Results Among the 55 cases, there were EEG abnormalities in a total of 48 cases （87.27%）. Among the cases in 3 groups of mild, morderate and severe symptom group, the comparison of abnormalities and abnormal degree in EEG, the difference were statistically significant （P〈0.001）. It revealed that more abnormalities in EEG more severity of patients′ conditions according to the comparison of prognosis among the normal group in EEG, mild abnormal, moderate abnormal, severe abnormal group in EEG, the differences have statistical significance （P〈0.001）. It revealed that more abnormalities in EEG worse prognosis. Conclusion EEG examination can be used as important reference index of diagnosis and prognosis evaluation in patients with viral encephalitis.
