Brain death diagnostic criteria: critial review

Over an eight year period diagnostic criteria of brain death were analysed in 117 patients. Duration of irreversible coma, level of consciousness expressed with Glasgow Coma Score (GCS), brain stem reflexes, spinal reflexes, EEG izoelectric pattern and apnea test were correlated. Correlations were shown using the statistical method of multiple regression analysis. Diagnoses of brain death were made after 60 hours in reanimation area. Level of consciousness expressed with GCS did not influence duration of coma. Isoelectric EEG pattern registered, three times after six hour interval, was the main criterion for the decision of brain death. Spinal reflexes were sometimes present when isoelectric pattern and obstruction of cerebral circulation were found. Maximal correlation was found between isoelecric EEG and absence of brain stem reflexes. Apnea test had maximal correlation with absence of brain stem reflexes.
