Construction Methods and Influencing Factors on Animal Model of Sepsis

Abstract

Sepsis is a common acute and critical illness, and its pathogenic mechanism is complex, often involving multiple organs and systems in the body. Various factors such as inflammatory response, immune dysfunction, and coagulation dysfunction are connected into an interconnected and mutually influencing network system, aggravating the severity of the disease. At present, the case fatality rate of sepsis is about 25%, which is a serious threat to human health. Establishing a stable and reliable experimental animal model of sepsis is an important means to understand the mechanism of host defense regulation in the early stage of infection, the mechanism of host response disorder in the stage of disease progression and to study the therapeutic effect of new therapeutic drugs. At present, there are many methods to establish animal models of sepsis, and there are many influencing factors. Therefore, this paper reviewed the preparation methods and influencing factors of animal models of sepsis, in order to provide some references for researchers to select suitable animal models.
