title: [Auditory evoked potentials of the brain stem in brain death].
abstract: Brainstem auditory evoked responses were recorded in a neurosurgical intensive care unit in 38 patients who had all the clinical criteria for brain death. Of the brain-dead patients, 65.8% never showed a response. 3.42% showed a type I wave, which was unilateral in 26.3% and bilateral in the other 7.9%. Types II to VII waves were never seen. An increase in latency of type I waves (2.25 +/- 0.24 ms) was noted. The interest and the limits of this non invasive electrophysiologic technique for the diagnosis of brain death are discussed.
