Non-Heart-Beating Organ Donation: A Defense of the Required Determination of Death

Published online by Cambridge University Press:  01 January 2021

Extract

The family of a patient who is unconscious and respirator-dependent has made a decision to discontinue medical treatment. The patient had signed a donor card. The family wants to respect this decision, and agrees to non-heart-beating organ donation. Consequently, as the patient is weaned from the ventilator, he is prepped for organ explantation. Two minutes after the patient goes into cardiac arrest, he is declared dead and the transplant team arrives to begin organ procurement. At the time retrieval begins, it is not certain that the patient's brain is dead or that cardiac function cannot be restored. Procurement follows uneventfully, and two transplantable kidneys are retrieved.

Many people now consider such cases of non-heart-beating organ donation to be ethically permissible. However, widespread disagreement persists as to how such practices are to be justified and whether such practices are compatible with the Uniform Declaration of Death Act (UDDA). In this paper, I argue that non-heart-beating organ donation can be ethically justified, that in the justified cases the patients are in fact dead, and that the early declarations of death required for such donation do comply with the UDDA.

The “dead-donor rule” is a name loosely used to denote two related and widely accepted ethical norms: “vital organs should only be taken from dead patients, and correlatively, living patients must not be killed by organ retrieval.” Youngner, S.J. Arnold, R.M., “Ethical, Psychological, and Public Policy Implications of Procuring Organs from Non-Heart-Beating Cadaver Donors,” JAMA, 269 (1993): 2769–74, at 2771. Although it is typically discussed as an ethical norm governing organ procurement, it is generally assumed that a violation of it, even with consent, would constitute euthanasia and violate state laws.CrossRefGoogle Scholar

Throughout this paper, I will refer to circulatory-respiratory (CR) criteria rather than to the more common cardiopulmonary criteria. Though this is somewhat more cumbersome, a rationale for this choice is provided in Shewmon, D.A., “Brainstem Death, Brain Death, and Death: A Critical Re-Evaluation of the Purported Equivalence,” Issues in Law and Medicine, 14 (1998): 125–45. D. Alan Shewmon writes: “Neither spontaneous heartbeat nor breathing through the lungs is essential for life (as cardiopulmonary bypass machines effectively prove), but circulation and chemical respiration are.” Id. at 126. Moreover, the term cardiopulmonary death might be taken by some to denote death of the heart and lungs, rather than death of the whole organism using CR criteria.Google Scholar
Although some (see infra note 5) had recommended that brain death provide the only criteria for determining death (whether directly diagnosed or inferred using CR criteria), the President's Commission stood by a bifurcated system of determining death. However, it appears that their rationale was that the public needed time to adjust to conceiving death in neurological terms, rather than that death could occur in the absence of brain death. See President's Commission, supra note 2, at 59.Google Scholar

The Institute of Medicine (IOM) study surveyed the sixty-three organ procurement organizations in the United States about their NHBD protocols. IOM received twenty-nine protocols. Apparently, nearly half did not mention a specific waiting time. Twelve specified waiting a few minutes (ranging from one to five), and several specified that procurement is to begin immediately after cardiac arrest is verified. IOM recommends a five-minute waiting period. However, it suggests that this waiting period could be shortened in the future. See id. at 60.Google Scholar

Both David Cole and Tom Tomlinson defend as adequate the Pittsburgh protocol's criteria for death, but express concerns that the donors will not be brain dead. Shewmon defends the use of a protocol similar to that recommended in this paper, but he explicitly claims that such donors are not dead. See Shewmon, supra note 3. Interestingly, a recent survey suggests that, within the transplant community, concepts of death have become so consciousness-oriented that only about 25 percent support procuring organs from a donor before brain death has been ascertained. This is true of a population in which 62 percent supported organ procurement from anencephalic and persistent vegetative state patients.

Clearly, these tests should change as our ability to detect loss of circulation and respiration improve, and our knowledge of the conditions that affect the ability to autoresuscitate. However, changes in tests will not affect the criteria defended here unless it turns out that the waiting times necessary, say, to verify the inability to autoresuscitate, coincide with brain death or are so long that they affect organ viability. Current evidence suggests that this is unlikely.Google Scholar

See DeVita, M., “The Death Watch: Certifying Death Using Cardiac Criteria” (1999) (unpublished), cited here with permission. To paraphrase somewhat, the basic finding of Michael DeVita's study is the following. Nature seems to have established: (1) a fairly rigid and short time frame during which autoresuscitation is possible; (2) a less rigid and longer time frame during which clinical resuscitation following aggressive intervention is possible; and (3) a remarkably flexible and significantly longer time frame during which experimental and ex vivo resuscitation is possible. Regarding autoresuscitation, DeVita examines 112 reported cases as described in 7 studies across a 58-year period. In only two cases did spontaneous recovery occur after sixty-five seconds. Significantly, in both of these cases, the patients clearly had not met death criteria according to the Pittsburgh protocol. In the first, the patient was apneic but there was no evidence that circulation was absent; in the second, there was no apnea, suggesting that brain activity, and hence circulation, had not fully stopped. From this data, DeVita concludes that spontaneous recovery after two minutes is “extremely unlikely.”Google Scholar

Jr. et al., Commentary, “Clear Thinking and Open Discussion Guide IOM's Report on Organ Donation,” Journal of Law, Medicine & Ethics, 26 (1998): 166–68. Perhaps the most significant aspect of this reply is that the committee members did what they thought they were asked to do. Specifically, they were asked by the Department of Health and Human Services to investigate the possibilities for non-heart-beating organ donation “… without violating prevailing ethical norms regarding the rights and welfare of donors.” See, Institute of Medicine, supra note 6, at 7. That the dead-donor rule is a prevailing ethical norm, at least within the relevant professional organizations, is attested to by the American Medical Association and the United Network for Organ Sharing.

Id. at 58. The President's Commission explicitly addresses the concept of death as the moment when the soul leaves the body. This view was treated as possibly providing a standard for secular action, but as less desirable than the other concept of death, which was deemed more verifiable. Nevertheless, loss of psychophysical unity seems to imply precisely the reintroduction of this second concept of death. See id. at 42–43.Google Scholar
Indeed, it seems contradictory to say that death is both a process and an event. However, Viktor Frankl once asserted that the apparently contradictory views of the person presented by behavioristic and psychoanalytic psychology can be reconciled if one accepts that they present different dimensions of the person. He illustrates his dimensional ontology with the observation that a three-dimensional figure like a cylinder may cast contradictory two-dimensional shadows, for example, rectangular or circular—depending on the direction from which light is cast on it. See Frankl, V.E., The Will to Meaning (New York: Meridian, 1988): at 23. By conceiving death as one phenomenon with different dimensions, biological and metaphysical (spiritual), perhaps these contradictions may turn out to be only apparent.Google Scholar

Although many different experiences are sometimes lumped together under the heading of near-death experiences (NDEs), in this section the focal instances of NDEs are those arising from cardiac arrest with apnea and unconsciousness (so-called clinical death). Reference will be made only to the work of those authors who collected data systematically, who attempted to verify claims when possible, and who attempted to reduce NDEs to more familiar phenomena. For a general overview of NDEs, see Lundahl, C.R., ed., A Collection of Near-Death Research Readings (Chicago: Nelson-Hall Publishers, 1982).

Though using looser criteria than Michael Sabom and Kenneth Ring, a 1982 Gallup poll estimated that eight million persons in the United States have had a NDE. See Gallup, G. Jr., Adventures in Immorality (New York: McGraw-Hill, 1982).Google Scholar
Both Ring and Sabom address the claim that NDEs are like drug-induced hallucinations. See Ring, (1982), supra note 36; and Recollections of Death, supra note 35. The most developed reductionistic account of NDEs as being like drug-induced hallucinations is Siegel, R.K., “The Psychology of Life After Death,” American Psychologist, 35 (1980): 911–31.

Though familiar with many aspect of resuscitation, in 80 percent of the cases, the non-NDE patients' accounts included obvious errors, such as describing medical resuscitation as involving mouth-to-mouth resuscitation, presenting misconceptions about cardiac massage (for example, as involving a blow to the back, hitting the solar plexus, massaging the heart muscle directly with one's hands), or misconceptions about cardiac defibrillation and how the electric shock is delivered. Most of Sabom's NDE group reported fairly nonspecific descriptions of the events surrounding resuscitation, claiming that their attention was more focused on the NDE event itself and the amazing emotions. However, what was reported by these groups appears consistent with what happened and no errors were found. In the six cases he examined in which specific descriptions were given, the reports appeared extremely accurate and veridical. See Recollections of Death, supra note 35.Google Scholar
In fact, the case against reductionist explanations is much stronger than these authors seem to notice, for the simple reason that dream states and other altered states of consciousness, such as trance and hypnosis, produce highly active, even if unusual, electroencephalogram (EEG) readings, whereas after fifteen seconds of cardiac arrest (the minimum time typical of Sabom's NDE patients), the EEG becomes isoelectric.

I am not simply repeating the views of Tomlinson, supra note 9. Tomlinson defends the idea that the Pittsburgh protocol for NHBDs provides an ethical determination of death. However, he contrasts this with a determination of ontological death. Although I agree that the Pittsburgh protocol uses an ethically adequate notion of irreversibility, irreversibility is not a necessary characteristic of ontological death.Google Scholar

I do not defend any particular NHBD protocol, nor do I provide an ethical analysis of NHBD protocols in general.

Among those who agree that physicians should never kill, some have asked whether it would be wrong to harvest vital organs prior to death if, in certain highly controlled situations, harvesting does not hasten death. (That is, they ask whether we could use a weak version of the dead-donor rule.) Two things can be said in response. First, proposals of this sort typically only arise because individuals do not accept brain death or the CR criteria proposed here for determining death of the human being. They then paint pictures in which a brain-dead patient (not dead according to their criteria) is put on cardiopulmonary bypass, the heart is removed, and then the patient is allowed to die as cardiopulmonary life-support is withdrawn. See Luetz, M., “Organspende ist keine Toetung auf Verlangen,” in Hoff, In der Smitten, supra note 27, at 496–99. Alternatively, they describe a situation in which a NHBD has kidneys removed prior to death, but at a point when loss of kidneys will not cause death, because the heart has stopped beating and anoxia will kill the patient. See Shewmon, supra note 3. I disagree that such donors are not already dead. Because such donors are the only candidates in which vital organs could theoretically be procured without hastening death, it follows that there are no such cases. Second, some of the concerns that lead one to respect the dead-donor rule may also lead one to reject use of the weak version of the dead-donor rule. At least in the scenario depicted by Luetz, a cause of death is still introduced, one that hastens the strictest medical irreversibility of the state of CR loss—a form of irreversibility that is essential to death in their accounts. Thus, the issues of dominion and public perception again arise.Google Scholar
