Abstract

With 4 Channel Nocolet-CA 1000 clinical averager, somatosensory evoked potentials(SSEP), brainstem auditory evoked potentials(BAEP) and visual evoked potentials(VEP) were studied in 23 patients who fulfilled the clinical criteria for brain death. The results were as follows : 1) In SSEP, all patients had identifiable Erb's point wave and 11 out of 23 patients(48%) had cervical portion wave, but none of these patients had identifiable cortical portion wave. 2) In BAEP, 19 out of 23 patients(83%) had no identifiable BAEP waveforms, including wave I, and 4 patients(17%) had only wave I. 3) In VEP, 15 out of 23 patients(65%) had no identifiable VEP waveforms and 8 patients(35%) had short latency-low amplitude wave with no any of the longer latency components of central system origin.
