Normothermic machine perfusion is a medical technique used to preserve and maintain organs outside the body before transplantation. This method involves pumping a nutrient-rich solution through the organ at normal body temperature, which helps keep the cells alive and functioning. It mimics the natural conditions of the body, allowing for better preservation compared to traditional cold storage methods. This technique is particularly beneficial for organs like the liver and kidneys, as it can improve their viability and function after transplantation. By enhancing the quality of the organs, normothermic machine perfusion can lead to better outcomes for patients receiving transplants.
