Purpose: We evaluated the effect of an extracellular phosphate-buffered lung preservation solution (EP-TU solution) on acute postoperative graft function and recipient survival in a Japanese series of cadaveric lung transplantation. Methods: The subjects were ten patients who received lung grafts preserved with EP-TU solution at three of four designated lung transplant centers between 2000 and 2005. Three of the patients underwent single lung transplantation and seven underwent bilateral lung transplantation. Postoperative graft function was evaluated by primary graft dysfunction (PGD) grade (0-3), arterial oxygen tension/inspired oxygen fraction (PaO 2/FiO 2) ratio, and the previously reported chest roentgenogram score (CRS, 0-4) during the first 48 h after intensive care unit admission. Survival rates were also calculated. Results: The average graft ischemic times for the first and second grafts were 431 and 571 min, respectively. The average PGD grade ranged from 0.5 to 1.0 and the average PaO 2/FiO 2 ratio ranged from 350 to 400 Torr during the 48 h. The average CRS was always under 1.0. Survival rates at 30 days and 5 years were 90 and 80%, respectively. Conclusions: EP-TU solution promoted excellent postoperative lung graft function and enhanced recipient survival rates, despite a long average preservation time.
