Abstract
The authors evaluated auditory evoked steady state rest potentials at 40 Hz (SSR40Hz) in 21 post-trauma coma patients and compared their pre dictive value for prognosis of survival and quality of life with the r esults of the electroencephalogram (EEG), the computed tomography (CT) scan, and the Glasgow Coma Scale. SSR40Hz potentials recorded immedia tely after trauma had a maximum (100%) sensibility and specificity for a fatal prognosis and a high value for life prognosis. Consequently t hey appear to be a useful parameter for deciding on organ explant proc edures. The EEG was more reliable in predicting a quality of life prog nosis.
