脑外伤后综合征患者脑电图和脑干听觉诱发电位异常分析

目的探讨脑外伤后综合征（PTBS）的脑电图（EEG）、脑干听觉诱发电位（BAEP）特点。方法对本院2005年9月至2010年10月门诊及住院就诊的659例患者诊断为PTBS行EEG和BAEP检查,并与662名健康志愿者的EEG、BAEP作对照分析。结果 PTBS病患EEG轻度异常533例（80.9%）,中度异常6例（0.9%）,重度异常0例（0%）。与正常组比,有显著差异（P〈0.01）。PTBS病患检测BAEP结果显示,BAEPI波潜伏期与对照组相比差异无显著意义（P〉0.05）。BAEP其他波潜伏期及峰间期均延长,与对照组有显著差异（P〈0.001）。EEG异常越重,BAEP异常率越高,BAEP异常也越明显。结论 EEG与BAEP联合应用,可以评估脑外伤患者的预后。

Electroencephalogram and brain stem auditory evoked potential detection in the post-traumatic brain syndrome patients

Objective To explore the characteristics of electroencephalogram(EEG),brain stem auditory evoked potential(BAEP) in patients with post-traumatic brain syndrome(PTBS).Methods EEG and BAEP detection were performed in 659 patients with PTBS and 662 health patients.Results There were 533 cases of PTBS patients with mildly abnormal EEG(80.9%),6 cases with moderate abnormalities(0.9%),0 cases with severe abnormalities(0%).Compared with the control group,there was significant difference(P<0.01).There was no signif...
