Bioética en donantes en asistolia controlada

Las campañas de prevención y promoción de salud, así como los avances en las medidas terapéuticas destinadas a los pacientes neurocríticos, han logrado reducir la incidencia de pacientes con injuria encefálica aguda (IEA) que evolucionan a la muerte encefálica (ME). Sin embargo, en la mayoría de los países de América Latina, los órganos perfusibles aptos para trasplante (TX) provienen de donantes fallecidos en ME. La donación en asistolia (DA), y en particular la donación en asistolia controlada (DAC), constituye una opción aceptada y válida para la obtención de órganos que contribuiría a la disminución de las listas de espera para trasplante. Durante el proceso de DAC, se aplican conceptos con fuerte impronta bioética cuya aplicación resulta fundamental en el momento de la toma de decisiones. El presente artículo tiene el objetivo de analizar dichos conceptos con la finalidad de otorgar herramientas válidas al equipo asistencial para aquellos procesos en los que existe deliberación moral, como ocurre en la donación de órganos en asistolia controlada, considerada parte integral de los cuidados al final de la vida.

Campaigns for health prevention and promotion, along with advancements in therapeutic measures for neurocritical patients, have succeeded in reducing the incidence of patients with acute brain injury (ABI) progressing to brain death (BD). However, in most Latin American countries, suitable perfusable organs for transplantation (TX) come from deceased donors in brain death (BD). Donation after circulatory death (DCD), particularly controlled donation after circulatory death (cDCD), represents an accepted and valid option for organ procurement that would contribute to reducing transplant waiting lists. During the cDCD process, strong bioethical principles are applied, and their implementation is crucial when making decisions. The purpose of this article is to analyze these concepts, aiming to provide valid tools to the healthcare team for processes involving moral deliberation, such as controlled circulatory death organ donation, considered an integral part of end-of-life care.

As campanhas de prevenção e promoção da saúde, bem como os avanços na medidas terapêuticas voltadas para pacientes neurocríticos conseguiram reduzir a incidência de pacientes com lesão cerebral aguda que evoluem para morte encefálica (ME). No entanto, na maioria dos países latino-americanos, os órgãos que podem ser perfundidos adequados para transplante (TX) vêm de doadores falecidos em ME. A doação em assistolia e em particular a doação em assistolia controlada (DAC),é uma opção aceita e válida para a obtenção de órgãos, o que contribuiria para a redução das listas de espera para transplantes. Durante o processo DAC, são aplicados conceitos com forte cunho bioético, que são fundamentais na o momento da tomada de decisão. Este artigo tem como objetivo analisar esses conceitos, com o objetivo de oferecer ferramentas válidas à equipe de saúde, para os processos em que há deliberação moral como ocorre na doação de órgãos em assistolia controlada considerada parte integrante dos cuidados de fim de vida.

Papel de la perfusión normotérmica con oxigenación de membrana extracorpórea en la donación en asistolia controlada en España / Role of normothermic perfusion with ECMO indonation after controlled cardiac death in Spain

Spain has become one of the most active countries in donation after controlled cardiac death, using normothermic abdominal perfusion with ECMO in more than 50% of all donors – a situation contributed to by the creation of mobile teams to support hospitals lacking this technology. The donation process must be respectful of the wishes and values of the patients and their relatives, especially if there is pre mortem manipulation, and the absence of cerebral perfusion should be guaranteed. The liver is the most benefited organ by reducing biliary complications as well as the loss of grafts. In renal transplantation, the technique could contribute to reduce the incidence of delayed graft function. In addition, the procedure is compatible with surgical rapid recovery in hypothermia when there is also lung donation. The future lies in the consolidation of cardiac donation by extending normothermic perfusion to the thoracic cavity (AU)

España se ha convertido en uno de los países más activos en donación en asistolia controlada incorporando la perfusión abdominal normotérmica con ECMO en más del 50% de los donantes, a lo que ha contribuido la creación de equipos móviles para apoyo a hospitales carentes de esta tecnología. El proceso de donación debe ser respetuoso con los deseos y valores del paciente y sus familiares, especialmente si hay manipulación pre mortem, y debe asimismo garantizar la ausencia de flujo cerebral. El hígado es el órgano más beneficiado al reducirse las complicaciones biliares, así como la pérdida de injertos. En el trasplante renal podría contribuir a reducir la incidencia de retraso en la función inicial del injerto; además, el procedimiento es compatible con la cirugía súper rápida en hipotermia cuando también hay donación pulmonar. El futuro pasa por la consolidación de la donación cardíaca al extender la perfusión normotérmica a la cavidad torácica (AU)
