Donor shortage urges optimal use of all lungs available. Ex vivo lung perfusion (EVLP) is a method to evaluate lung function before implantation. EVLP was performed in pigs to evaluate lung function, using two different clinical non-heart-beating (NHS) donor protocols: flush perfusion and topical cooling after 1-h warm ischaemia (n = 5 each). Secondly, we investigated whether EVLP can be used for 6 h ex vivo machine preservation (n = 4). In comparison with topical cooling, flush perfusion preserved lung function better during EVLP. During 6 h normothermic EVLP, gas exchange remained stable; however, the pulmonary artery pressure and ventilation pressure showed a significant increase. EVLP is a reliable method for evaluation of lung graft function. Flush perfusion with Perfadex is preferred above topical cooling in NHB lung donation. Six-hour normothermic EVLP is feasible but should be further improved to make ex vivo machine preservation or treatment of lung grafts successful.
