[Improvements in lung preservation: 3 years' experience with a low-potassium dextran solution]

Area of Science:

• Cardiology
• Transplantation Medicine
• Pulmonary Medicine

Background:

• Lung preservation solution quality is vital for successful lung transplantation.
• Euro-Collins (EC) solution was the standard, but a new low potassium dextran solution, Perfadex (PER), was introduced in 2000.

Purpose of the Study:

• To compare the clinical outcomes of lung transplantation using Perfadex (PER) versus Euro-Collins (EC) preservation solutions.

Main Methods:

• A retrospective analysis compared 68 lung transplants using PER with 68 historical controls using EC.
• Patient demographics, donor causes of death, transplant types, and perioperative data were analyzed.

Main Results:

• While waiting list times were longer for PER recipients, more double lung transplants were performed (78% vs. 53%).
• Early graft function was similar, but severe graft failure (PaO2/FiO2 < 150 mm Hg) was significantly lower with PER (16% vs. 37%).
• No differences were observed in extracorporeal circulation, ischemia time, mechanical ventilation, or mortality.

Conclusions:

• Perfadex (PER) significantly reduced the incidence of severe ischemia-reperfusion graft injury by 50% in the early recovery phase post-lung transplantation.
• The study supports the use of Perfadex as a superior lung preservation solution for improving early graft outcomes.
