Mechanism and research status of hemoperfusion in endotoxemia treatment

Abstract

Endotoxemia is a pathophysiological manifestation caused by the release of large amounts of endotoxin from bacteria in the blood or in the lesion. It can cause multiple organ failure, irreversible shock, and even death. The mortality rate of endotoxemiaIt is high. Bacterial endotoxin is the main cause of endotoxemia. At present, there is no safe and effective drug to treat endotoxemia in clinic. Research shows that blood purification can effectively reduce endotoxin level in the blood, then achieve the goal of treatment of endotoxemia. In this paper, the pathogenesis of endotoxemia, the development of hemoperfusion therapy technology, the mechanism and research status of endotoxin adsorption by different hemoperfusion resin were discussed, and the performance and safety requirements of hemoperfusion adsorbent materials for endotoxemia treatment were studied, so as to provide theoretical support for the synthesis of new hemoperfusion adsorption materials for the treatment of endotoxemia.
