A New Defense of Brain Death as the Death of the Human Organism

This paper provides a new rationale for equating brain death with the death of the human organism, in light of well-known criticisms made by Alan D Shewmon, Franklin Miller and Robert Truog and a number of other writers. We claim that these criticisms can be answered, but only if we accept that we have slightly redefined the concept of death when equating brain death with death simpliciter. Accordingly, much of the paper defends the legitimacy of redefining death against objections, before turning to the specific task of defending a new rationale for equating brain death with death as slightly redefined.

Coding the Dead: Cardiopulmonary Resuscitation for Organ Preservation

BACKGROUND

There is lack of consensus in the bioethics literature regarding the use of cardiopulmonary resuscitation (CPR) for organ-preserving purposes. In this study, we assessed the perspectives of clinicians in critical care settings to better inform donor management policy and practice.

METHODS

An online anonymous survey of members of the Society of Critical Care Medicine that presented various scenarios about CPR for organ preservation.

RESULTS

The email was sent to 10,340 members. It was opened by 5,416 (52%) of members and 405 members (4%) completed the survey with few missing data. A majority of respondents (81%) answered that donation status should not influence whether CPR is performed on an imminently dying patient. There was very strong agreement (>85%) that 1) CPR should be performed on a registered donor who experiences a cardiac arrest with an unknown code status before death by neurological criteria (DNC) and 2) CPR should be performed if the patient is not a registered donor and experiences cardiac arrest but the surrogate/power of attorney (POA) has not yet been approached regarding code status and donation. When a registered donor with a DNR order experiences cardiac arrest before DNC, 98% of respondents would not perform CPR. However, after DNC, respondents were evenly divided on whether they would (49%) or would not (51%) perform CPR on a registered donor with an undocumented code status. When asked whether consent should be required for CPR for organ-preserving purposes, 39% answered "Yes" when a patient arrests before DNC and 48% answered "Yes" when a patient arrests after DNC (P = 0.2).

CONCLUSIONS

The majority of respondents did not consider donor status relevant to CPR decisions before DNC, and virtually all would respect a DNR order in a registered donor before DNC. Respondents were divided about the need for an affirmative consent for CPR for organ-preserving purposes both before and after DNC.

Requests for Accommodation in Brain Death Cases: Emerging Role for Pediatric Palliative Care

Death by neurologic criteria is a diagnosis that has presented complexities since its inception and pediatric cases are no exception. While rare, families may request accommodation to deviate from the traditionally defined diagnostic pathway based on their beliefs, mistrust of the diagnosis, or other complex reasons. Palliative care consultation offers a unique clinical perspective to complement the work of intensivists to support families through the diagnosis and possible resolution around accommodation requests. With misinformation and high-profile cases widely visible to the public through the media, these requests require a thoughtful and informed clinical approach by all members of the interdisciplinary clinical team. Common themes in many of these cases are trauma, bias and their impact on caregivers. We use a case-based approach to explore these complexities and clinical tools.

Prolonged duration of apnea test during brain death examination in a case of intraparenchymal hemorrhage

Objective:

Apnea test is required as part of the brain death examination. The duration of the apnea test is variable but typically requires 8–10 min. Prolonged apnea tests have been reported in the setting of hypothermia. Here, we describe a case of prolonged duration of apnea test secondary to a phenomenon called cardiac ventilation.

Methods:

The patient presented in coma with brainstem areflexia after having an intracerebral hemorrhage resulting in subfalcine, central, uncal, and tonsillar herniations. Confounding variables were excluded. Brain death testing was performed, and she was found to have brainstem areflexia. Pre-requisites for apnea test were then met.

Results:

Apnea testing, however, was prolonged at 110 min. When reconnected to ventilator, it was noted that she had small (30–35 cc) tidal volumes at a rate of her heart rate without respiratory effort. Ancillary testing with four-vessel cerebral angiogram confirmed cerebral circulatory arrest.

Conclusions:

To our knowledge, this is the longest reported case of apnea testing during brain death testing. Variables known to cause a delay in the rise of carbon dioxide (PaCO₂) levels were excluded. We suspect the hyperdynamic cardiac state caused cardiac ventilations resulting in slow increase in carbon dioxide levels.
