Alternative solution for ex vivo lung perfusion, experimental study on donated human lungs non-accepted for transplantation

PURPOSE: To evaluate a new perfusate solution to be used for ex vivo lung perfusion.METHODS: Randomized experimental study using lungs from rejected brain-dead donors harvested and submitted to 1 hour of ex vivo lung perfusion (EVLP) using mainstream solution or the alternative.RESULTS: From 16 lungs blocs tested, we found no difference on weight after EVLP: Steen group (SG) = 1,097±526g; Alternative Perfusion Solution (APS) = 743±248g, p=0.163. Edema formation, assessed by Wet/dry weigh ratio, was statistically higher on the Alternative Perfusion Solution group (APS = 3.63 ± 1.26; SG = 2.0...
