“…Various methods and substances to improve lung graft preservation during cold ischemia, such as pulmonary surfactant, liquid perfluorocarbon (PFC), complement inhibitors, and nitrites, as well as inhalation of hydrogen sulfide or nitric oxide, have been tested experimentally 1 2 However, the standard method of lung graft preservation is still perfusion with a cold low-potassium dextran (LPD) solution via the pulmonary artery (antegrade perfusion) or via the pulmonary veins (retrograde perfusion), together with the use of pulmonary vasodilators and partial inflation of the lungs with oxygen during storage 2 .…”
