The authors evaluated auditory evoked steady state rest potentials at 40 Hz (SSR40Hz) in 21 post-trauma coma patients and compared their predictive value for prognosis of survival and quality of life with the results of the electroencephalogram (EEG), the computed tomography (CT) scan, and the Glasgow Coma Scale. SSR40Hz potentials recorded immediately after trauma had a maximum (100%) sensibility and specificity for a fetal prognosis and a high value for life prognosis. Consequently they appear to be a useful parameter for deciding on organ explant procedures. The EEG was more reliable in predicting a quality of life prognosis.
作者评估了21名创伤后昏迷患者的40赫兹听觉诱发电位稳态静息电位（SSR40Hz），并将其对生存预后和生活质量的预测价值与脑电图（EEG）、计算机断层扫描（CT）以及格拉斯哥昏迷量表的结果进行了比较。创伤后立即记录的SSR40Hz电位对胎儿预后具有最大（100%）的敏感性和特异性，对生命预后具有较高价值。因此，它们似乎是决定器官移植手术的一个有用参数。脑电图在预测生活质量预后方面更可靠。
