62例病毒性脑炎脑电图与临床及CT分析

Analysis of electroencephalogram and clinic,CT in 62 viral encephalitis cases

为探讨病毒性脑炎（病脑）患者脑电图（EEG）与临床及CT之间的关系，将临床确诊的62例病脑患者进行EEG与CT检查，对其EEG异常的阳性率、异常程度与病程、临床表现、CT之间的关系进行比较分析，并作统计学处理。结果发现，发病10天以内EEG中、重度异常39倒（78%），与10天以后比较有显著性差异（P＜0．001）。EET可表现为三种形式：以弥漫性异常为主（51.5％）；弥漫性异常伴局灶慢波（32．3%）；局灶性异常（16．2%）。EEG与CT之间无明显相关性（P＞0．05）。提示：EEG检查对病脑的诊断、鉴别诊断，以及动态观察病情、判断预后有重大意义。CT不能取代EEG。

To investigate the relation between electroencephalogram (EEG) and clinic, CT in viral encephalitis patients EEGs were made in 62 viral encephalitis patisents who had been diagnosed definitly. The relation between the positive rate of abnormal EEG. abnormal degree and duration of dissease, clinic manifastation, CT were compared and anlysed. Disposal of statistics was made. The results showed that the number of moderate and severe abnormal EEG in ten dsys are 39(78% ). It was significantly higher than that after ten days (P<0.001). The abnormal EEGs were mainly of three types: prevailing diffuse changes (51. 5% ) diffuse abnormality with focal slow wave (32.3% ), and focal changes (16.2% ). No significant relation of abonrmal EEG to CT was noted (P > 0.05). These findings suggested that the examination of EEG has an important significance for diagnosis, diffirential diagnosis, evaluating the prognosis of viral encephalitis. EEG was not substituted by CT.
