Cardiac transplantation: surgical considerations and early postoperative management.
The limited availability of donor hearts is the major constraint to the expanded application of cardiac transplantation. As many as 25% of potential recipients will die before a donor becomes available. Since 1986, hospitals that receive Medicare and Medicaid funds have been required to ask family members of all brain-dead patients who are potential donors whether they have considered organ donation. The United Network for Organ Sharing is responsible for the national organ procurement and transplantation network as well as the national organ transplantation scientific registry. The increasing occurrence of multiorgan donation is amplifying the demands for intensive-care management of donors. Donor and recipient are matched on the basis of ABO blood group and body size. The donor operation can be performed in any standard operating room. Although the maximal acceptable ischemic time for a donor heart is 4 to 6 hours, briefer preservation times result in better hemodynamic performance after transplantation and a significantly lower 30-day mortality. The technique of choice in most medical centers is orthotopic cardiac transplantation. Postoperatively, most patients remain in the intensive-care unit for 1 or 2 days and in the hospital for 1 to 2 weeks. Standard intensive-care procedures after transplantation, including nursing and cardiovascular management as well as the treatment of failure of the donor heart, are reviewed. A comprehensive educational program for patients and their families should optimize the outcome after heart transplantation. The overall charges for heart transplantation averaged $114,000 in 1987, 80% of which were hospital charges.(ABSTRACT TRUNCATED AT 250 WORDS)
