ABSTRACT
BACKGROUND:
In search of the ideal composition of the flush solution for pulmonary preservation, we studied the effects of prostaglandin E1 (PGE1) and prostacyclin as an additive to Euro-Collins solution (ECS) on pulmonary hemodynamics and gas exchange in a porcine single lung transplantation model using extracorporeal circulation and right heart bypass.METHODS:
Twenty-two pigs served as donors. The animals were randomized to receive either modified ECS alone (control group, n = 8), ECS with 100 micrograms/L of PGE1 (PGE1 group, n = 6), or ECS with 200 micrograms/L of prostacyclin (prostacyclin group, n = 8). Left lung transplantation was performed in 22 recipients after approximately 4 hours of cold ischemia.RESULTS:
Carbon dioxide elimination was significantly depressed in the two prostaglandin groups, and the use of PGE1 was associated with a significant decrease in arterial oxygen tension compared with the control group. Both drugs were inefficient in alleviating the increase in pulmonary vascular resistance after transplantation.CONCLUSION:
The use of prostaglandins as constituents of the flush solution was not followed by any improvement of early graft function after cold ischemia.
