Liberalization of donor criteria in lung and heart-lung transplantation.

Abstract

Since March 1986, we have performed 26 heart-lung transplantations, 42 single-lung transplantations, 9 bilateral single-lung transplantations, and 1 double-lung transplantation. The original lung donor requirements were as follows: age less than 40 years, no smoking history; no gram-negative rods or fungus on sputum Gram stain; arterial oxygen tension greater than 140 mm Hg on an inspired oxygen fraction of 0.40; no infiltrate or pneumothorax on the chest radiograph; and donor height within 15 cm (6 inches) of recipient height. As the number of potential recipients increased, so did the waiting time. To counter this delay, during the past year we have liberalized our donor criteria. We now accept lung donors up to age 60 years. Any kind of smoking history is acceptable unless there is chronic obstructive pulmonary disease or pulmonary fibrosis on the chest radiograph. Sputum must be free from fungus, but gram-negative rods are treated with appropriate antibiotics. The arterial oxygen tension on an inspired oxygen fraction of 0.40 should be greater than 100 mm Hg, and a small pulmonary infiltrate is not worrisome. This liberalization of the donor pool for lung and heart-lung transplantation has not adversely affected early outcome.
