“…43 The reason the need-driven exchange of gasses is so important relates to 41 Of course, the degree of responsiveness the hypothalamus is capable of should matter in tests for the irreversibility of total brain failure, since, according Widjicks, "[s]timulation of the posterior hypothalamus" causes arousal (Wijdicks 2010, 52). We should also be sensitive to detections of auditory evoked potentials, which may indicate some remaining brainstem functioning (for more commentary on the significance of this phenomena, see Laureys 2005, 904;Facco and Machado 2004). How these tests should proceed is a beyond the scope my inquiry.…”

Brain Death as the End of a Human Organism as a Self-moving Whole

The biophilosophic justification for the idea that “brain death” (or total brain failure) is death needs to support two claims: (1) that what dies in human death is a human organism, not merely a psychological entity distinct from it; (2) that total brain failure signifies the end of the human organism as a whole. Defenders of brain death typically assume without argument that the first claim is true and argue for the second by defending the “integrative unity” rationale. Yet the integrative unity rationale has fallen on hard times. In this article, I give reasons for why we should think of ourselves as organisms, and why the “fundamental work” rationale put forward by the 2008 President’s Council is better than the integrative unity rationale, despite persistent objections to it.

“…As ondas estão presentes mesmo na vigência de doses elevadas de anestésicos ou barbitúricos. Na morte encefálica, as ondas evocadas no tronco cerebral (III a VI) desaparecem de modo precoce e irreversível, caracterizando a falência funcional desta estrutura 13 .…”

O conceito de morte encefálica surgiu concomitantemente com a medicina de transplantes na década de 1960, existindo assim a necessidade de determinação científica e legal de em que momento um paciente pode ser considerado em morte encefálica e, assim, um potencial doador de órgãos e tecidos. O exame clínico deverá avaliar quatro pontos fundamentais que são as bases para a determinação clínica de morte encefálica. Neste artigo, revisamos os conceitos de diagnóstico clínico de morte encefálica e os principais exames complementares confirmatórios.

“…Para el diagnóstico de ME, se utilizan los PES del nervio mediano estudiando los PE generados en los diferentes niveles de la vía sensitiva: nervio periférico, raíz espinal, columna posterior de la médula, lemnisco medio, tálamo contralateral y corteza sensitiva del lóbulo parietal contralateral. En ME sólo persisten las ondas generadas en el plexo braquial y la médula espinal, y desaparecen las ondas de origen intracraneal 25,26 .…”

Brain death has been recognized by the scientific community as the person's death, and accepted in the legislation of different countries. Brain death is defined as the irreversible ending of the functions of all the intracranial neurological structure in both the brain and brain stem. This clinical situation appears when intracranial pressure exceeds the patient's systolic blood pressure, leading to brain circulatory arrest. The most frequent are cerebral hemorrhage and cranioencephalic trauma. Clinical diagnostic must be done by doctors with expertise in neurocritical patient treatment. This diagnosis is based on a systematic, complete and extremely rigorous clinical examination that confirms a non-reactive coma, absence of brain stem reflex, and absence of spontaneous breathing. Instrumental tests may be obligatory in some cases, this depending on each country. Electroencephalogram and evoked potentials are the electrophysiological tests used. In patients treated with sedative drugs, cerebral blood flow evaluation tests, such as cerebral angiography, transcranial Doppler or 99Tc-HMPAO scintigraphy, will be used. More than 92% of the transplants performed in Spain are performed with brain death donor organs. Brain death confirmation is a high responsibility act, with medical, ethical and legal significance since it requires removal of all artificial support, or organs extraction for transplant. Extensive knowledge on its diagnostic and correct decision making avoid unnecessary use of resources and improves management of organs for transplant.
