目的

研究重型颅脑外伤后昏迷患者脑电图(EEG)反应性,探讨EEG反应性定量分析在准确评估重型颅脑外伤后昏迷患者预后中的作用。

方法

选取自济南军区总医院神经外科2013年3月至2014年6月符合纳入标准的66例重型颅脑外伤后昏迷患者进行EEG反应性检查,并观察分析随时间推移EEG反应性绝对功率变化百分比,比较其差异。

结果

(1)痛刺激引起的EEG反应性的阳性率(44%~56%)高于声刺激(10.17%~16.67%)和光刺激(0%~13.33%)的阳性率,差异有统计学意义(P<0.05)。(2)EEG反应性对患者预后预测的准确度分别为:入院时77.27%,1周76.27%,2周86.53%,3周91.11%,4周88.89%。(3)EEG反应性的定量研究证实,各监测时间点绝对功率变化百分比呈持续阳性的脑外伤后昏迷患者,其预后良好率为82.6%;呈持续阴性的脑外伤后昏迷患者,其预后不良率为100%;在监测时间段EEG反应性由阴转阳的脑外伤后昏迷患者,其预后良好率为62.5%;而监测时间段EEG反应性由阳转阴的脑外伤后昏迷患者,其预后不良率为92.9%。

结论

EEG反应性及定量分析可作为预测颅脑外伤后昏迷患者预后的重要手段,对临床重型颅脑外伤后昏迷患者预后的评估具有具体指导意义。

Objective

To assessed electroencephalographic (EEG) reactivity of patients with trauma coma to make quantitative analysis of EEG reactivity. To explore the role of quantitative analysis of EEG reactivity on the evaluation for prognosis of patients with trauma coma.

Methods

Sixty-six patients with trauma coma were selected for this study that was in line with the standard of study in 2013 March to 2014 June in Department of Neurosurgery of Ji’nan Military General Hospital of Chinese people′s Liberation Army. EEG reactivity of these patients were recorded on admission, a week, two weeks, three weeks and 4 weeks after trauma. Then, the changes in percentage of absolute power for EEG reactivity were analyzed quantitatively in different groups.

Results

(1) Pain-induced percentage of reactivity was higher (44%-56%) than auditory reactivity (10.17%-16.67%) and visual reactivity (0%-13.33%) (P<0.05). (2) The prognosis of patients with EEG reactivity of the accuracy of prediction is respectively: 77.27% on admission, 1 week 76.27%, 2 weeks 86.53%, 3 weeks 91.11%, 4 weeks 88.89%. (3) The rate for well prognosis in trauma coma patients displaying positive percentage changes in absolute power for EEG reactivity during the whole recording duration was 82.6%, while, the rate for poor prognosis in trauma coma patients displaying negative percentage changes during the whole recording duration was 100%. The rate for well prognosis for those patients displaying dynamic (from negative to positive) percentage was 62.5%, while, the rate for poor prognosis for those patients displaying dynamic (from positive to negative) percentage was 92.9%.

Conclusion

EEG reactivity and its quantitative analysis is an important method for the evaluation on prognosis of patients with trauma coma.
