An international team of experts provides evidence-based criteria and recommends clinical and apnea testing for the determination of brain death or death by neurologic criteria. Robert Truog, MD, joined contributors to the World Brain Death Project in presenting an international consensus report on the criteria for brain death diagnoses, or the determination of death by neurologic criteria (BD/DNC). If the clinical examination cannot be completed, ancillary testing may be considered with blood flow studies or electrophysiologic testing. 41 (Paolin), sensitivity is 53%, but the specificity is not calculated as the article is a study of consecutive brain death patients. In their paper, the consensus authors stated that the first criteria that must be fulfilled prior to evaluating a patient for BD/DNC is to establish a neurologic diagnosis that could lead to either complete or irreversible loss of all brain function. None of the patients recovered. Consensus statements were made based on literature searches of the Cochrane, Embase, and MEDLINE databases. The World Brain Death Project was undertaken to establish minimum standards for diagnosing brain death/death by neurologic criteria (BD/DNC) in children and adults across a broad range of settings and clinical circumstances. Less than 1 percent of all people are ever pronounced brain dead. Machado C. Jahi McMath: a new state of disorder of consciousness. In these circumstances, it is important to remark that “BD/DNC should not be diagnosed until supratentorial and infratentorial blood flow is lost, even if the clinical examination and apnea test are suggestive of BD/DN (1).”, Challenges in Clinical Electrocardiography, Clinical Implications of Basic Neuroscience, Health Care Economics, Insurance, Payment, Scientific Discovery and the Future of Medicine, United States Preventive Services Task Force.
