Organ preservation refers to the techniques used to maintain the viability of organs outside the body for transplantation. This process is crucial for ensuring that organs remain functional until they can be transplanted into a recipient. Methods include cold storage and perfusion, which help to slow down cellular metabolism and reduce damage. Advancements in organ preservation have improved transplant success rates. Techniques such as hypothermic preservation and machine perfusion allow for longer storage times and better organ function post-transplant. These innovations are vital in addressing the shortage of available organs and improving outcomes for patients in need of transplants.
