Brain death (BD) is a distinct mode of death in pediatric intensive care units, accounting for 16–23% of deaths. Coma, absent brainstem reflexes, and apnea in a patient with acute irreversible neurological insult should alarm the attending physician to start the appropriate actions to establish or refute the diagnosis for BD. BD diagnosis is clinical, starting with the preconditions that should be met, and based on the examination of all brainstem reflexes, including the apnea test. Apnea testing should be conducted according to standard criteria to demonstrate the absence of spontaneous respirations, in the case of an intense ventilatory stimulus, setting at increased PaCO2 levels ≥60 and ≥20 mm Hg, compared to baseline. When elements of clinical examination and/or apnea test cannot be performed, ancillary studies to demonstrate the presence/absence of electrocerebral silence and/or cerebral blood flow are guaranteed. Two clinical examinations by qualified physicians at set intervals are required. Time of death is the time of second examination and ventilator support should stop at that time, except for organ donation. The use of check list in documentation of BD helps in the uniformity of diagnosis and fosters further trust from medical, family, and community personnel.
