Significance of early acoustic evoked potentials in the diagnosis of brain death

Abstract

Tests of early acoustic evoked potentials in 49 patients in whom clinical and EEG criteria indicated brain death demonstrated a bilateral loss of brainstem-generated components III to V in 12.6%, a loss of the components II-V in 16.8% and a loss of all early acoustic evoked potentials in 47.4%. This method, practicable in an intensive care unit, seems thus suitable for demonstrating loss of brainstem function as demanded for diagnosis of brain death.
