动态脑电图与常规脑电图应用于病毒性脑炎诊断的效果分析

目的:探讨动态脑电图与常规脑电图应用于病毒性脑炎的应用价值。方法:选取150例病毒性脑炎患者,随机分为两组,每组各75例,常规脑电图(REEG)组采用常规脑电图检查,动态脑电图(AEEG)组采用动态脑电图检查;观察并记录脑电图异常率,不同程度病情脑电图异常率的例数,评价动态脑电图与常规脑电图对病毒性脑炎的检测灵敏度和准确度。结果:AEEG组检出的脑电图异常率明显高于REEG组(P0.05)。不同程度病情脑电图检出的患者比例,两组相比,差异没有统计学意义(F=-0.085,P0.05)。REEG组中,轻度与中度病毒性脑炎检出率相比,差异没有统计学意义(P0.05),中度与重度病毒性脑炎检出率相比,差异没有统计学意义(P0.05),重度病毒性脑炎检出率明显高于轻度(P0.05)。AEEG组中,轻度与中度病毒性脑炎检出率相比,差异没有统计学意义(P0.05),重度病毒性脑炎检出率明显高于中度和轻度(P0.05),AEEG组重度病毒性脑炎检出率明显高于REEG组(P0.05)。结论:动态脑电图作为一种无创性检查,对于病毒性脑炎具有极好的检出率,灵敏度高,适用于病毒性脑膜炎的早期辅助诊断。

Application Value of Ambulatory EEG and Routine EEG in Diagnosis of Viral Encephalitis

ABSTRACT Objective: To discuss the application value of ambulatory electroencephalogram (AEEG), and routine electroencep- halogram (REEG) in the diagnosis of viral encephalitis. Methods: 150 patients with viral encephalitis were selected and randomly divided into two groups. The REEG group (75 cases) was given routine EEG to diagnose, and the AEEG group (75 cases) was given ambulatory EEG to diagnose. The application value of ambulatory EGG and routine EEG in diagnosis of viral encephalitis was evaluated by the ab- normal rate of EEG, the number of cases with abnormal EGG in diagnosis of viral encephalitis in different degree. Results: The abnormal rate of EGG of the AEEG group was higher than that of the REEG group (P<0.05). The proportion of patients through EEG had no statis- - tical significance in the diagnosis of viral encephalitis in different degree between two groups (F=-0.085, P>0.05). In REEG group, there were no statistical significance in the detection rate of the mild and moderate viral encephalitis (P>0.05), and there were no statistical signif- icance in the detection rate of moderate and severe viral encephalitis (P>0.05), but the detection rate for the severe viral encephalitis was higher than that of mild viral encephalitis (P<0.05). In AEEG group, there were no statistical significance in the detection rate of the mild and moderate viral encephalitis (P>0.05), but the detection rate for the severe viral encephalitis was higher than that of mild and moderate viral encephalitis (P<0.05). The detection rate of severe viral encephalitis in AEEG group was higher than that of the REEG group(P<0.05). Conclusion: The ambulatory EEG was a non-invasive examination with excellent detection rate and high sensitivity on the detec- tion of viral encephalitis, so it is suitable for the early diagnosis of viral encephalitis.
