Abstract
Background: Despite many efforts to improve organ preservation and recipient survival, overall lung transplant (LT) mortality is still high. We aimed to investigate the impact of ‘prophylactic’ veno-arterial extracorporeal membrane oxygenation (VA ECMO) and tacrolimus on 72-h primary graft dysfunction (PGD) and 30-day acute cellular rejection, respectively. Methods: All consecutive LT patients admitted to the Intensive Care Unit of the Padua University Hospital (February, 2016–2022) were screened. Only adult patients undergoing first bilateral LT and not requiring cardio-pulmonary bypass, invasive mechanical ventilation, and/or ECMO before LT, were included. A propensity score weighting analysis was employed to account for the non-random allocation of the subjects to different treatments. Results: A total of 128 LT recipients were enrolled. Compared to the ‘off-pump’-group (n.47, 37%), ‘prophylactic’ VA ECMO (n.51,40%) recorded similar 72-h PGD values, perioperative blood products and lower acute kidney dysfunction. Compared with cyclosporine (n.86, 67%), tacrolimus (n.42, 33%) recorded a lower risk of 30-day cellular rejection, kidney dysfunction, and bacteria isolation. Conclusions: ‘Prophylactic’ VA ECMO recorded 72-h PGD values comparable to the ‘off-pump’-group; while tacrolimus showed a lower incidence of 30-day acute cellular rejection.
