摘要 目的采用脑电图(EEG)与磁共振(MRI)预测颅脑损伤后长期意识障碍患者的预后。方法对53例重度颅脑外伤后意识障碍>2周的成人患者进行预后评估,选择MRI T2加权像与EEG的Young分级标准对预后进行分析。生活质量以6个月后格拉斯哥预后评分(GOS)为标准进行判别。结果本组颅脑损伤的患者采用单纯的EEG分级预测患者预后的敏感性为60.86%,特异性为90.00%,准确率为77.36%;如果EEG结合MRI T2加权像进行统计分析,则可弥补EEG检测的不足,其敏感性、特异性、准确率均有提高,分别为84%、96.3%和90.57%,两者评估患者的预后呈明显负相关(r=-0.749,P<0.01)。结论采用EEG分级联合MRI方法可提高预测评估颅脑损伤后长期意识障碍患者的脑功能状态敏感性、特异性和准确率,可在临床选用。
