When successful solid organ transplantation was initiated almost 40 years ago, its current success rate was not anticipated. But continuous efforts were undertaken to overcome the two major obstacles to success: injury caused by interrupting nutrient supply to the organ and rejection of the implanted organ by normal host defense mechanisms. Solutions have resulted from technologic medical advances, but also from using organs from different sources. Each potential solution has raised ethical concerns and has variably resulted in societal acclaim, censure, (...) and apathy. Transplant surgery is now well accepted, and the list of transplant candidates has grown far quicker than the availability of organs. More than 30,000 patients were awaiting organs for transplantation at the end of March 1993. While most organs came from donors declared dead by brain criteria, the increasing shortage of donated organs has prompted a reexamination of prior restrictions of donor groups. Recently, organ procurement from donors with cardiac death has been reintroduced in the United States. This practice had been mostly abandoned by the U.S. and some, though not all, other countries. Transplantation has been more successful using organs procured from heart-beating, "brain dead" cadavers than organs from non-heart-beating cadavers. However, recent advances have led to success rates with organs from non-heart-beating donors that may portend large increases in organ donation and procurement from this source. (shrink)

In the latter half of the twentieth century, developed countries of the world have made tremendous strides in organ donation and transplantation. However, in this area of medicine, Japan has been slow to follow. Japanese ethics, deeply rooted in religion and tradition, have affected their outlook on life and death. Because the Japanese have only recently started to acknowledge the concept of brain death, transplantation of major organs has been hindered in that country. Currently, there is a dual definition of (...) death in Japan, intended to satisfy both sides of the issue. This interesting paradox, which still stands to be fully resolved, illustrates the contentious conflict between medical ethics and medical progress in Japan. (shrink)

Procurement of organs from non-heart-beating cadaver donors raises concerns. Standards for optimal patient care during withdrawal of life-sustaining therapy are evolving and continue to be debated and studied. Consensus on specific procedures and methods has not been attained, however, and protocols for the procurement of organs from patients following the withdrawal of life-sustaining therapies may compromise the evolving standards and harm the patient and the attendant family. In addition, there is little evidence to suggest that such protocols will significantly increase (...) the number of organs procured. "Non-heart-beating cadaver" protocols that do not give comprehensive attention to optimal patient/family care at the time of withdrawal of life-sustaining therapy ought not to be endorsed. (shrink)

Two contemporary strategies in cadaver organ transplantation, both with the potential to affect significantly expanding organ transplant waiting list sizes, have evolved: elective ventilation and use of nonheart-beating donors. Both are undergoing a period of critical review. It is not clear how widely EV is practiced around the world. In Great Britain, the Royal Devon and Exeter Hospital was the first hospital to develop an EV protocol, in 1988, after which other British hospitals followed suit. In the 1980s, new NHBD (...) protocols of two distinct types were implemented worldwide, although both rely on death confirmed by traditional cardiopulmonary criteria. The first type involves the removal of organs immediately after death, the preeminent example being the University of Pittsburgh Medical Center Protocol. The second involves the perfusion and cooling of kidneys immediately following death and subsequent organ removal. Protocols of this type have sprung up in Holland, Great Britain, Italy, France, Spain, Japan, and the United States. (shrink)
