We appreciate the comments of Drs. Doyle and Robichaud. We agree that there are many patients who suffer massive brain injury and who do not meet neurologic criteria (either clinical or radiographic) to establish death. Under current clinical and professional norms, and as understood by the general public, these individuals cannot become solid organ heart beating donors. The ethical norm that guides a gift of donation is the dead-donor rule: that organs and tissues are retrieved from individuals only after death.
Individuals who suffer massive brain injuries that die determined by cardiac and not neurologic criteria can give a gift of donation. A donation of tissue such as skin, heart valves, corneas etc. also provides life-enhancing benefit to recipients. A gift of tissue donation is as important as a gift of organ donation; the altruism by the family is the same in both circumstances. It may be that organs should also be retrieved from individuals that die from cardiac criteria (non-heart beating organ donation), but at best this may only modestly increase the supply of life-enhanching organs such as kidneys, and less so increase life-saving organs such as livers. It will not increase the supply of life-saving organs such as hearts or lungs.
Whether the dead-donor rule should be abandoned in favour of less restrictive criteria for donation is a topic beyond the scope of our review.1
