Feasibility of lung microdialysis to assess metabolism during clinical ex vivo lung perfusion.

Background: Lung metabolism during ex vivo lung perfusion (EVLP) is increasingly studied. Microdialysis (MD) allows metabolic monitoring by sampling parenchymal interstitial fluid. This study investigated lung metabolism using MD during EVLP and evaluated whether microdialysate metabolites could improve selection and discriminate outcome of donor lungs.
