Perspective The NEW ENGLAND JOURNAL of MEDICINE july 19, 2007 n engl j med 357;3 www.nejm.org july 19 , 2007 209 the supply. In 2006, there were about 29,000 solid-organ trans- plantations; as of June 2007, there were about 97,000 people on wait- ing lists for organ transplantation. About three of every four or- gans that are transplanted are recovered from deceased donors. The most rapid increase in the rate of organ recovery from de- ceased persons has occurred in the category of donation after “cardiac death” — that is, a death declared on the basis of cardiopulmonary criteria (irre- versible cessation of circulatory and respiratory function) rather than the neurologic criteria used to declare “brain death” (irrevers- ible loss of all functions of the entire brain, including the brain stem). Organs were recovered from 645 donors after cardiac death in 2006, as compared with 189 in 2002; these donors accounted for 8% of all deceased donors in 2006 (see bar graph). At the Organ Pro- curement Organization at the Uni- versity of Wisconsin, the New En- gland Organ Bank in the Boston area, and the Finger Lakes Donor Recovery Network in New York, such donors accounted for more than 20% of all deceased donors. Since 1968, when an ad hoc committee at Harvard Medical School proposed a brain-based definition of death that became widely accepted, organs for trans- plantation have been removed pri- marily from hospitalized patients who have been pronounced dead on the basis of neurologic crite- ria, when they are on ventilators and their hearts continue to func- tion. The continued circulation of blood helps to prevent the organs from deteriorating. Obtaining organs from donors after cardiac death — when the heart is no longer beating — is the approach that was generally followed in the 1960s and earlier. Today, such donations typically in- volve patients who are on a ven- tilator as the result of devastat- ing and irreversible brain injuries, such as those caused by trauma or intracranial bleeding. Poten- tial donors might also have high spinal cord injuries or end-stage musculoskeletal disease.
