Consider this scenario. 56 This view also implies that death can be declared in other conditions in which consciousness seems impossible due to the dysfunction, destruction, or the absence of cortical … Nonetheless, there remains a substantial gap between the number of donated organs and the number of people who could benefit from them,85 so any proposed changes to organ procurement practices should take into account potentially harmful consequences, particularly an exacerbation of the gap between demand and supply of organs. As Bernat et al wrote, “This criterion [of brain death] is perfectly correlated with the permanent cessation of functioning of the organism as a whole”,61 and as Bernat later emphasized, “With the loss of the critical system [the brain], the organism loses its life-characterizing processes, and entropy (disorder) inevitably increases”.62.

Furthermore, most (but not all) participants who were willing to donate organs “after death” were also willing to donate in irreversible coma with organ retrieval causing death, and willingness to donate after death correlated positively with willingness to donate in irreversible coma.84 This survey suggests that many members of the US public would support organ procurement in situations that violate the dead donor rule, casting doubt on the assertion that the dead donor rule is necessary to preserve trust and organ donation rates (at least in the USA), and thus on the cogency of Bernat’s83 defense of the status quo.

Rabbinical Council of America. Instead, this defense of the dead donor rule is a version of rule consequentialism, in which a general rule is proposed on the grounds that, on the whole, following the rule will have better consequences than not following it. However, lethal organ procurement is permissible, they argue, when it is tied to a valid decision to withdraw life-sustaining treatment and with a valid consent for lethal organ removal.50,81,82 On this view, current organ procurement practices are ethically objectionable because of the lack of valid informed consent (since donors are not informed that organ retrieval causes death), but heart-beating organ removal would be ethically unproblematic if valid consent were obtained.

Almost immediately, physicians had ethical concerns about maintaining the physiological functioning of patients they believed to be “hopelessly unconscious”,12 or in a state of coma dépassé (beyond coma).13 This included concerns about the just use of limited resources, financial burdens to families and hospitals, and the emotional toll on families whose grieving process seemed to be held in limbo, with a family member who was not yet dead and buried, but in a hopeless condition from which he or she could not recover.14 Further, this was an era prior to the seminal Karen Ann Quinlan case,15 which set a legal precedent in the USA for the permissibility of removing life-sustaining treatment. According to the Uniform Determination of Death Act, adopted by most states, death is defined as “irreversible cessation of circulatory and respiratory functions” or “irreversible cessation of all functions of the entire brain, including the brain stem.” There are no ethical issues in the care of someone who is brain-dead, because the patient is now a corpse, McCullough said. Nair-Collins M. Taking science seriously in the debate on death and organ transplantation. Yet, presumably, the very same ethical considerations regarding precedent autonomy, surrogate decision-making, and the right to refuse treatment, would apply to Muñoz’s case whether she had no brainstem reflexes, or just one, in which case she could not have been declared dead by neurological criteria, and the Texas Advance Directives Act would have applied.
