Various professional societies have formulated guidelines for EEG recording techniques in the evaluation of brain death. The active cable electrode EEG system can measure biosignals in very small dimensions and can record bioelectric brain activity with few artifacts. It can record bioelectric signals that cannot be picked up by conventional techniques. EEG registrations by the active cable electrode showed clear residual bioelectric activity in a patient with severe head injury in whom conventional EEGs with two system showed isoelectric recordings. Simultaneously, TCD showed residual perfusion in both middle cerebral arteries.
Brain death marks human death in the scientific medical sense.
Brain death can be determined in any critical care unit on the basis of clinical findings only, without further testing. References 1 . Schwarz G. Dissoziierter Hirntod. Buchner H, Schuchardt V. Reliability of electroencephalogram in the diagnosis of brain death. EEG bei klinischem Hirntodsyndrom.
