Thoracic Organ

Procurement of thoracic organs can be divided into two major categories- donation after brain death (DBD) or donation after circulatory determination of death (DCDD). In this section we will focus primarily on DBD, which is the commoner of these two or at times referred to as standard procurement. DCDD is a relatively new and promising field that has helped ameliorate donor shortage, aided by the latest advances in medical technology. However, DBD continues to be the major avenue of organ donation. There are several different combinations of thoracic procurement surgeries: heart, double lung, single lung/ 2-single lungs, heart-lung en bloc for transplantation, Double Lung procurement for Bronchial arterial revascularization, Heart and Lung procurement in DCDD donors with the OCS, NRP or Lungs for EVLP.

Death Determination

Brain death is the state of irreversible loss of the clinical functions of the brain. A patient must meet strict criteria to be declared brain dead. They must have suffered a known and demonstrably irreversible brain injury and must not have a condition that could render neurologic testing unreliable. If the patient meets these criteria, a formal brain death examination can be performed. The three findings in brain death are coma or unresponsiveness, absence of brainstem reflexes, and apnea. Brain death is closely tied to organ donation, because brain-dead patients represent approximately 90% of deceased donors and thus a large majority of donated organs. This review details a definition and overview of brain death, determination of brain death, and controversy over brain death, as well as the types of organ donation (living donation versus deceased donation), donation after brain death, and donation after cardiac death. A figure presents a comparison of organ donation after brain death and after cardiac death, and a table lists the American Academy of Neurology Criteria for Determination of Brain Death. This review contains 1 highly rendered figure, 3 table, and 20 references.

The Catholic Church

The introduction of the “brain death” criterion constitutes a significant paradigm shift in the determination of death. The perception of the public at large is that the Catholic Church has formally endorsed this neurological standard. However, a critical reading of the only magisterial document on this subject, Pope John Paul II's 2000 address, shows that the pope's acceptance of the neurological criterion is conditional in that it entails a twofold requirement. It requires that certain medical presuppositions of the neurological standard are fulfilled, and that its philosophical premise coheres with the Church's teaching on the body-soul union. This article demonstrates that the medical presuppositions are not fulfilled, and that the doctrine of the brain as the central somatic integrator of the body does not cohere either with the current holistic understanding of the human organism or with the Church's Thomistic doctrine of the soul as the form of the body. Summary The concept of “brain death” (the neurological basis for legally declaring a person dead) has caused much controversy since its inception. In this regard, it has been generally perceived that the Catholic Church has officially affirmed the “brain death” criterion. The address of Pope John Paul II in 2000 shows, however, that he only gave it a conditional acceptance, one which requires that several medical and philosophical presuppositions of the “brain death” standard be fulfilled. This article demonstrates, taking into consideration both the empirical evidence and the Church's Thomistic anthropology, that the presuppositions have not been fulfilled.

Donation After Brain Death

This chapter discusses death and dying, and includes discussion on confirming death using neurological criteria (brainstem death), withdrawing and withholding treatment, organ donation after brain death (DBD), and organ donation after circulatory determination of death (DCD). Death is common in the intensive care unit (ICU) and it is important to identify patients whose condition meets the criteria for brainstem death testing as well as patients where continued treatment is not considered to be in their overall best interests. Confirming death using neurological criteria allows the relatives to be presented with the certainty of a diagnosis of death whether organ donation is possible or not. Decisions to withraw treatment are common in the ICU and are associated with approximately 50% of all deaths in the ICU. The decision is made by the multidisciplinary team in consultation with the patient’s relatives and taking into account the patient’s values and preferences. In both situations the possibility of organ donation should be considered and explored, and, when it is a possibility, it should be routinely offered to the relatives as an end-of-life care option.

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

Transplant Team

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 concept of brain death was proposed more than 50 years ago and it has been incorporated in laws and clinical practice, but it remains a source of confusion, debate, and litigation. Because of persistent variability in clinical standards and ongoing controversies regarding policies, the Uniform Law Commission (ULC), which drafted the Uniform Determination of Death Act (UDDA) in 1980, has appointed a committee to study whether the act should be revised. This article reviews the history of the concept of brain death and its philosophical underpinnings, summarizes the objections that have been raised to the prevailing philosophical formulations, and proposes a new formulation that addresses those objections while preserving current practices.

Apnea Testing

Ethical concerns regarding the conceptual framework for the determination of death by neurological criteria, including several clinical and diagnostic practices, are addressed. The significance of a diagnosis of brain death, diagnostic criteria, and certain technical aspects of the brain-death exam are presented. Standard and ancillary tests that typically help achieve prudential certitude that an individual has died are indicated. Ethical concerns surrounding interinstitutional variability of testing protocols are evaluated and considered, as are potential apnea-testing confounders such as hypotension, hypoxemia, hypercarbia, and penumbra effects during ancillary testing. Potential adjustments to apnea-testing protocols involving capnography, thoracic impedance monitors, or spirometers to assess respiratory efforts are discussed. Situations in which individuals determined to be brain dead “wake up,” or fail to manifest the imminent cessation of somatic functioning typically seen when supported only by a ventilator, are also briefly reviewed.
