Recent commentaries by Verheijde et al, Evans and Potts suggesting that donation after cardiac death practices routinely violate the dead donor rule are based on flawed presumptions. Cell biology, cardiopulmonary resuscitation, critical care life support technologies, donation and transplantation continue to inform concepts of life and death. The impact of oxygen deprivation to cells, organs and the brain is discussed in relation to death as a biological transition. In the face of advancing organ support and replacement technologies, the reversibility of (...) cardiac arrest is now purely related to the context in which it occurs, in association to the availability and application of support systems to maintain oxygenated circulation. The 'complete and irreversible' lexicon commonly used in death discussions and legal statutes are ambiguous, indefinable and should be replaced by accurate terms. Criticism of controlled DCD on the basis of violating the dead donor rule, where autoresuscitation has not been described beyond 2 minutes, in which life support is withdrawn and CPR is not provided, is not valid. However, any post mortem intervention that re-establishes brain blood flow should be prohibited. In comparison to traditional practice, organ donation has forced the clarification of the diagnostic criteria for death and improved the rigour of the determinations. (shrink)

Transplantation of vital organs has been premised ethically and legally on "the dead donor rule" (DDR)—the requirement that donors are determined to be dead before these organs are procured. Nevertheless, scholars have argued cogently that donors of vital organs, including those diagnosed as "brain dead" and those declared dead according to cardiopulmonary criteria, are not in fact dead at the time that vital organs are being procured. In this article, we challenge the normative rationale for the DDR by rejecting the (...) underlying premise that it is necessarily wrong for physicians to cause the death of patients and the claim that abandoning this rule would exploit vulnerable patients. We contend that it is ethical to procure vital organs from living patients sustained on life support prior to treatment withdrawal, provided that there is valid consent for both withdrawing treatment and organ donation. However, the conservatism of medical ethics and practical concerns make it doubtful that the DDR will be abandoned in the near future. This leaves the current practice of organ transplantation based on the "moral fiction" that donors are dead when vital organs are procured. (shrink)

Notwithstanding these wise pronouncements, my project here is to characterize the biological phenomenon of death of the higher animal species, such as vertebrates. My claim is that the formulation of “whole- brain death ” provides the most congruent map for our correct understanding of the concept of death. This essay builds upon the foundation my colleagues and I have laid since 1981 to characterize the concept of death and refine when this event occurs. Although our society's well-accepted program of multiple (...) organ procurement for transplantation requires the organ donor first to be dead, the concept of brain death is not merely a social contrivance to permit us to obtain the benefits of organ procurement. Rather, the concept of whole- brain death stands independently as the most accurate biological representation of the demise of the human organism. (shrink)

According to international scientific medical consensus, death is a biological, unidirectional, ontological state of an organism, the event that separates the process of dying from the process of disintegration. Death is not merely a social contrivance or a normative concept; it is a scientific reality. Using this paradigm, the international consensus is that, regardless of context, death is operationally defined as “the permanent loss of the capacity for consciousness and all brainstem function. This may result from permanent cessation of circulation (...) or catastrophic brain injury. In the context of death determination, ‘permanent’ refers to loss of function that cannot resume spontaneously and will not be restored through intervention.” The word “permanent” replaces “irreversible” (used in the United States’ 1980 Uniform Declaration of Death Act) in this new definition, arguably invented to allow donation after circulatory determination of death (DCDD) while still complying with the dead donor rule. I will show that this invention fails, for at least four reasons. (shrink)

The dead donor rule (DDR) governs procuring life-prolonging organs. They should be taken only from deceased donors. Miller and Truog have proposed abandoning the rule when patients have decided to forgo life-sustaining treatment and have consented to procurement. Organs could then be procured from living patients, thus killing them by organ procurement. This proposal warrants careful examination. They convincingly argue that current brain or circulatory death pronouncement misidentifies the biologically dead. After arguing convincingly that physicians already cause death by withdrawing (...) treatment, they claim no bright-line differences preclude organ removal from the living. The argument fails for those who accept the double effect doctrine or other grounds for distinguishing forgoing life support from active, intentional killing. If the goal is determining irreversible loss of somatic function, they correctly label current death pronouncement a “legal fiction.” Recognizing a second, public policy meaning of the term death provides grounds for maintaining the DDR without jeopardizing procurement.

Discussion of the “dead donor rule” is challenging because it implicates views about a wide range of issues, including whether and when patients are appropriately declared dead, the validity of the doctrine of double effect, and the moral difference between or equivalence of active euthanasia and withdrawal of life‐sustaining treatment. The DDR will be defined here as the prohibition against removal of organs necessary for the life of the patient—that is, the prohibition of intentionally ending the life of a patient (...) through organ removal. At a minimum, it is difficult not to see the DDR as grounded in a set of laws, norms, values, and practices that are firmly entrenched and have a great deal of philosophical, religious, and legal support. Obviously, the primary argument against the DDR is that it is highly desirable that we continue to procure organs for transplantation, combined with the belief that those from whom we often and possibly typically procure organs are not “really” dead. If donors are not really dead, then we are left with a dilemma: either we abandon organ procurement, or we abandon the DDR. Such a move should be taken only if the way we currently delineate the dead (those from whom it is acceptable to remove organs) cannot be maintained or defended. I will suggest that this is not the case. (shrink)

In this chapter, I review some of the background thinking concerning matters of moral status that I had developed in previous years and that I would now bring to the work of the Human Embryo Research Panel. Two ideas were at the forefront of my thinking. First, that biology usually offers not decisive "events" but only continuous processes of development. Second, in making status determinations we do not so much "identify" a point on a developmental continuum where moral respect should (...) be accorded as "choose" that point. These choices are "balancing decisions" in which the community of moral agents weighs its interests in protecting an entity against the burdens of doing so. After illustrating these two contentions, I consider some of the reasons why thinkers on the "right" and "left" of our bioethics debates have resisted or missed this basic insight. (shrink)

Critics of organ donation after circulatory death (DCD) argue that, even if donors are past the point of autoresuscitation, they have not satisfied the “irreversibility” requirement in the circulatory and respiratory criteria for determining death, since their circulation and respiration could be artificially restored. Thus, removing their vital organs violates the “dead-donor” rule. I defend DCD donation against this criticism. I argue that practical medical-ethical considerations, including respect for do-not-resuscitate orders, support interpreting “irreversibility” to mean permanent cessation of circulation and (...) respiration. Assuming a consciousness-related formulation of human death, I then argue that the loss of circulation and respiration is significant, because it leads to the permanent loss of consciousness and thus to the death of the human person. The DNR request by an organ donor should thus be interpreted to mean “do not restore to consciousness.” Finally, I respond to an objection that if “irreversibility” has a medical-ethical meaning, it would entail the absurd possibility that one of two individuals in the same physical state could be alive and the other dead—an implication that some think is inconsistent with understanding death as an objective biological state of the organism. I argue that advances in medical technology have created phenomena that challenge the assumption that human death can be understood in strictly biological terms. I argue that ethical and ontological considerations about our nature bear on the definition and determination of death and thus on the permissibility of DCD. (shrink)
