Abstract

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.
