For this purpose the organ should be perfused with organ preservative solution twice before it is transplanted to the recipient. The first perfusion is done just after the abdomen is opened at laporotomy and the second perfusion is done just after the organ has been removed from the donor. Commonly used preservative solutions include UW solution (University of Wisconsin) and Eurocollins solution.
