Organ preservation refers to the techniques used to maintain the viability of organs for transplantation. This process is crucial for ensuring that organs remain functional and healthy until they can be transplanted into a recipient. Methods include cooling the organs, using preservation solutions, and sometimes employing machine perfusion to keep blood flowing through the organ. Advancements in organ preservation have improved transplant success rates and expanded the time frame for organ viability. Techniques such as hypothermic preservation and normothermic machine perfusion are being researched and implemented to enhance the quality of preserved organs, ultimately benefiting patients in need of transplants.
