Electrophysiological neuromonitoring of brainstem auditory evoked potentials (BAEP), short-latency somatosensory evoked potentials (SSEP) and compressed spectral array (CSA) EEG can provide precise and immediate information concerning functional integrity of the brain, brainstem and upper spinal cord of severely brain-damaged patients. We applied this neuromonitoring system in the cases of 154 severely brain-damaged patients in order to evaluate its reliability in the diagnosis of brain death. In particular, this study considers the relationships between BAEP and neurological findings, conventional EEG findings and factors affecting final BAEP findings. ⋯ The one demonstrated loss of all BAEP waves 17 days after her accident, with recovery of waves I to V three months later. The temporal relationships in group B patients of the course of BAEP findings and the time of neurological brain death diagnosis are shown in Table 2 and Fig. 1. All but two of the 61 patients were followed up until final loss of BAEP waves (Fig. 1).(ABSTRACT TRUNCATED AT 400 WORDS)
