目的：目的探讨标准脑电图（EEG）对急性脑损伤昏迷后意识障碍患者意识恢复的预测价值。本文对46例昏迷后意识障碍的患者在入院时进行了脑电图检查（22例创伤性脑损伤患者，24例非创伤性脑损伤患者）。采用Synek（1988）量表对EEG异常进行量化，并将其与基础认知功能水平（LCF）量表评分及其3个月后的变化进行相关分析（p < 0.01），3个月后LCF评分变化（p < 0.01）; EEG评分仅与3个月后LCF评分变化相关结论：标准EEG，使用Synek量表分析，在两组意识障碍患者中具有良好的预后价值。这项工作可能对急性脑损伤昏迷后意识受损患者的临床护理，康复计划和医疗法律决策产生影响。(C)2009年国际临床神经生理学联合会。由Elsevier爱尔兰有限公司出版。保留所有权利。
Objective: To investigate the prognostic value of standard electroencephalogram (EEG) in predicting the improvement of the level of consciousness in patients suffering from severe disturbances of consciousness following coma caused by acute brain injuries.Methods: A standard EEG was recorded at admission in our rehabilitation department in a total of 46 patients with impaired consciousness states following coma (22 patients with traumatic brain injuries, 24 patients with non-traumatic brain injuries). We quantified the EEG abnormalities using the scale of Synek (1988) and correlated them with the basal level of cognitive functioning (LCF) scale score and with its variation after three months.Results: EEG scores correlated with LCF scores at admission (p < 0.01) and with LCF scores' variation after three months (p < 0.01) in patients with traumatic brain injury; EEG scores correlated only with LCF scores variation after three months (p < 0.01) in patients with non-traumatic brain injury.Conclusions: Standard EEG, analysed using the Synek scale, has a good prognostic value in both groups of patients with disorders of consciousness.Significance: This work may have implications for clinical care, rehabilitative programs and medical-legal decisions in patients with impaired consciousness states following coma due to acute brain injuries.
