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)

Controlled donation after circulatory determination of death (cDCDD) is an important strategy for increasing the pool of eligible organ donors.

Recent EEG studies on the early postmortem interval that suggest the persistence of electrophysiological coherence and connectivity in the brain of animals and humans reinforce the need for further investigation of the relationship between the brain’s activity and the dying process. Neuroscience is now in a position to empirically evaluate the extended process of dying and, more specifically, to investigate the possibility of brain activity following the cessation of cardiac and respiratory function. Under the direction of the Center for Healthy (...) Minds at the University of Wisconsin-Madison, research was conducted in India on a postmortem meditative state cultivated by some Tibetan Buddhist practitioners in which decomposition is putatively delayed. For all healthy baseline and postmortem subjects presented here, we collected resting state electroencephalographic data, mismatch negativity, and auditory brainstem response. In this study, we present HB data to demonstrate the feasibility of a sparse electrode EEG configuration to capture well-defined ERP waveforms from living subjects under very challenging field conditions. While living subjects displayed well-defined MMN and ABR responses, no recognizable EEG waveforms were discernable in any of the tukdam cases. (shrink)

The dead donor rule (DDR) originally stated that organ donors must not be killed by and for organ donation. Scholars later added the requirement that vital organs should not be procured before death. Some now argue that the DDR is breached in donation after circulatory determination of death (DCDD) programs. DCDD programs do not breach the original version of the DDR because vital organs are procured only after circulation has ceased permanently as a consequence of withdrawal of life-sustaining therapy. We (...) hold that the original rendition of the DDR banning killing by and for organ donation is the fundamental norm that should be maintained in transplantation ethics. We propose separating the DDR from two other fundamental normative rules: the duties to prevent harm and to obtain informed consent. (shrink)

ZusammenfassungIn zahlreichen Ländern nimmt die Zahl von Organspenden nach Kreislaufstillstand zu, obwohl in der Medizinethik verschiedene Aspekte der DCDD kritisch diskutiert werden. In unserer Arbeit identifizieren wir ethisch relevante Aspekte der DCDD basierend auf einer umfassenden Literaturanalyse. Wir fokussieren dabei insbesondere auf zwei Aspekte: vorbereitende Maßnahmen und Irreversibilität des Todeskriteriums. Danach untersuchen wir in einer weltweit durchgeführten Auswertung von Webseiten von Organspende-Organisationen und einer begleitenden Umfrage, inwieweit diese ethisch relevanten Aspekte von DCDD in der Information potenziell spendewilliger Personen eine Rolle (...) spielen. Es zeigt sich, dass in der Mehrheit der Webseiten der Organisationen auf die Thematik DCDD nicht oder kaum eingegangen wird, die befragten Verantwortlichen der Organisationen aber die Wichtigkeit der Aufklärung bei spendewilligen Personen betonen. Wir diskutieren diese Diskrepanz und weisen auf zentrale Punkte hin, über welche spendewillige Personen informiert werden sollen, wenn diese Form der Organspende in ihrem jeweiligen Land praktiziert wird. Zudem plädieren wir dafür, dass das Todeskriterium und die Prozeduren zur Todesfeststellung in der Transplantationsmedizin einheitlich sein sollen, um kritisch diskutierte Aspekte im Kontext der DCDD entschärfen zu können.
