Problems solved by technology

In recent years, LPD (low-potassium dextran) has been used as a lavage solution, and several reports have shown that its lung preservation effect is better than that of Euro-Collins solution and UW (University of Wisconsin) solution, and it is believed that it can better protect alveolar capillaries. Endothelial cells, but even so, are still not an ideal lavage fluid that can be widely used clinically. These factors lead to severe restrictions on the operation of lung donors, surgical arrangements, and even surgical operations, which have become an important obstacle to the development of lung transplantation

Abstract

A lavation liquid for the organ to be transplated contains K, Na, Mg, Cl, phosphate, sulfate, prostaglandin E1, gossypose, and low-molecular dextran. It can elongate the storage time of organ and increase survival rate of transplanted organ.

Description

technical field [0001] The invention relates to an organ transplantation technique, in particular to a lavage solution for lavaging organs to facilitate preservation and improve survival rate. Background technique [0002] Organ transplantation is called "the pinnacle of 21st century medicine". When entering the new century, organ transplantation has entered a new period of vigorous development. According to statistics from the Worldwide Transplant Center Directory (WTCD), so far more than 600,000 patients with incurable diseases have gained a second life through organ transplantation. After organ transplantation, they are healthy and live the same life as normal people; they are mentally healthy and energetic at work; women of childbearing age can conceive and give birth, and children can grow up healthily. In order to have a better prospect for organ transplantation, scientists from various countries are tirelessly exploring new fields. In order to develop the source of...
