早期拟诊为急性病毒性脑炎的脑电图分析

Analysis of EEG in early diagnosis of acute viral encephalitis

目的:分析早期拟诊为急性病毒性脑炎的脑电图价值。方法:将本院2014年12月至2016年2月接收并行早期拟诊的80例疑似急性病毒性脑炎患者分为两组,一组是研究组,有45例急性病毒性脑炎患者;另一组为常规组,有35例急性精神障碍患者,研究对比两组患者脑电图的差异,总结早期拟诊在急性病毒性脑炎患者脑电图中的应用价值。结果:早期急性病毒性脑炎患者α频带功率明显降低,两侧发生不对称现象和局灶性异常,差异对比具有统计学意义(P<0.05),其他脑波对比显示无统计学意义(P>0.05)。结论:在急性病毒性脑炎早期脑电图表现中,显示α频带功率降低,两侧不对称及局灶性异常,可为该疾病的临床早期诊断鉴别提供参考依据。

Objective：To analysis the early acute viral encephalitis value of electroencephalogram （eeg）examination.Methods：in our hospital in December 2014 to February 2016 receive parallel early examination of 80 patients with suspected acute viral encephalitis were divided into two groups,one group is the team,there are 45 cases of patients with acute viral encephalitis;Another group as normal group,35 cases of acute mental disorders,the study compared the difference of two groups of pa-tients with eeg,summarize the early examination on the application value of electroencephalogram （eeg）in patients with acute viral encephalitis.Results：The patients with acute viral encephalitis early alpha significantly lower frequency band power,a-symmetry occur on both sides of the draw focal abnormalities,compared statistically significant difference（P 〈 0.05 ）,other brain wave contrast showed no statistical significance（P 〉 0.05）.Conclusions：In acute viral encephalitis early electroencepha-lography （eeg）performance,according to alpha band power reduction,on both sides of the asymmetry and focal abnormal,is assumed to improve clinical early diagnosis of the disease to identify the reference.
