摘要 目的研究动态脑电图对于病毒性脑炎辅助诊断价值。方法在入院3 d内对临床拟诊为病毒性脑炎病人分别进行常规脑电图和动态脑电图检查,其中有40例确诊为病毒性脑炎,采用配对X2检验比较两种检查方法发现中度或重度异常脑电活动的几率。结果动态脑电图和常规脑电图的中度或重度脑电活动的发现率分别为80%、65%,有显著性差异(P<0.05);发现痫样放电的几率分别为40%、5%,有显著性差异(P<0.05)。动态脑电图检查发现40例病人的睡眠生理波都不清楚。结论动态脑电图对病毒性脑炎有重要的辅助诊断意义,相对于常规脑电图有更高的敏感性;睡眠节律紊乱是病毒性脑炎的特征。 Objective To explore the value of ambulatory electroencephalogram (AEEG) monitoring in the auxiliary diagnosis of viral encephalitis. Methods Patients paradiagnosised with viral encephalitis underwent AEEG and routine electroencephalogram (REEG) within 3 days after hospitalization, and 40 patients were finally diagnosed with viral encephalitis. Matched-pairs X^2 analysis was used to compare the rate of abnormal findings of level or high degree in AEFG and REFG. Results The rate of moderately or gravely abnormal fmdings observed in AEFG and REFG were 80% and 65% respectively (P〈0.05). The rate of epileptiform activity was 40% and 5% respectively(P〈0.05). Physiologic sleep wave presented in AEEG was unclear in 40 patients. Conclusion AEEG shows higher sensitivity in diagnosis of viral encephalitis than REEG. Sleep rhythm disorder is one of characters of viral encephalitis.
