[Correlations between EEG (FFT) and the degree of consciousness in patients in the early post-traumatic phase].
In 73 comatose patients after cerebral trauma a computer-assisted study was done prospectively in relation to the clinical findings, the course, morbidity, and mortality as well as computer analysed EEG. The patients were examined at the 3rd, 6th, and 9 th day after trauma. The state of consciousness was scaled in 10 points and correlated to the numerous EEG results (spectral analysis and power in the delta-, sigma-, alpha-, and beta-range). As well it shows, the alpha-band gives the best correlation to the clinical findings and permit a certain prognosis.
