  1. (1 other version)Brain death, states of impaired consciousness, and physician-assisted death for end-of-life organ donation and transplantation.Joseph L. Verheijde,Mohamed Y. Rady &Joan L. McGregor -2009 -Medicine, Health Care and Philosophy 12 (4):409-421.
    In 1968, the Harvard criteria equated irreversible coma and apnea with human death and later, the Uniform Determination of Death Act was enacted permitting organ procurement from heart-beating donors. Since then, clinical studies have defined a spectrum of states of impaired consciousness in human beings: coma, akinetic mutism, minimally conscious state, vegetative state and brain death. In this article, we argue against the validity of the Harvard criteria for equating brain death with human death. Brain death does not disrupt somatic (...) integrative unity and coordinated biological functioning of a living organism. Neurological criteria of human death fail to determine the precise moment of an organism’s death when death is established by circulatory criterion in other states of impaired consciousness for organ procurement with non-heart-beating donation protocols. The criterion of circulatory arrest 75 s to 5 min is too short for irreversible cessation of whole brain functions and respiration controlled by the brain stem. Brain -based criteria for determining death with a beating heart exclude relevant anthropologic, psychosocial, cultural, and religious aspects of death and dying in society. Clinical guidelines for determining brain death are not consistently validated by the presence of irreversible brain stem ischemic injury or necrosis on autopsy; therefore, they do not completely exclude reversible loss of integrated neurological functions in donors. The questionable reliability and varying compliance with these guidelines among institutions amplify the risk of determining reversible states of impaired consciousness as irreversible brain death. The scientific uncertainty of defining and determining states of impaired consciousness including brain death have been neither disclosed to the general public nor broadly debated by the medical community or by legal and religious scholars. Heart-beating or non-heart-beating organ procurement from patients with impaired consciousness is de facto a concealed practice of physician-assisted death, and therefore, violates both criminal law and the central tenet of medicine not to do harm to patients. Society must decide if physician-assisted death is permissible and desirable to resolve the conflict about procuring organs from patients with impaired consciousness within the context of the perceived need to enhance the supply of transplantable organs.

  • (Uncontrolled) Donation after Cardiac Determination of Death: A Note of Caution.Christopher James Doig &David A. Zygun -2008 -Journal of Law, Medicine and Ethics 36 (4):760-765.
    In this short article, we articulate a position that organ recovery from uncontrolled DCD — primarily patients who have suffered a cardiac arrest — is unlikely to result in a significant number of organs, and this small gain must be balanced against significant risk of unduly influencing resuscitation provider decision-making, and jeopardizing public trust in the propriety of organ donation and transplantation.

  • One or two types of death? Attitudes of health professionals towards brain death and donation after circulatory death in three countries.D. Rodríguez-Arias,J. C. Tortosa,C. J. Burant,P. Aubert,M. P. Aulisio &S. J. Youngner -2013 -Medicine, Health Care and Philosophy 16 (3):457-467.
    This study examined health professionals’ (HPs) experience, beliefs and attitudes towards brain death (BD) and two types of donation after circulatory death (DCD)—controlled and uncontrolled DCD. Five hundred and eighty-seven HPs likely to be involved in the process of organ procurement were interviewed in 14 hospitals with transplant programs in France, Spain and the US. Three potential donation scenarios—BD, uncontrolled DCD and controlled DCD—were presented to study subjects during individual face-to-face interviews. Our study has two main findings: (1) In the (...) context of organ procurement, HPs believe that BD is a more reliable standard for determining death than circulatory death, and (2) While the vast majority of HPs consider it morally acceptable to retrieve organs from brain-dead donors, retrieving organs from DCD patients is much more controversial. We offer the following possible explanations. DCD introduces new conditions that deviate from standard medical practice, allow procurement of organs when donors’ loss of circulatory function could be reversed, and raises questions about “death” as a unified concept. Our results suggest that, for many HPs, these concerns seem related in part to the fact that a rigorous brain examination is neither clinically performed nor legally required in DCD. Their discomfort could also come from a belief that irreversible loss of circulatory function has not been adequately demonstrated. If DCD protocols are to achieve their full potential for increasing organ supply, the sources of HPs’ discomfort must be further identified and addressed. (shrink)
