Experimental Models of Source Control

• Various animal models such as for endotoxemia, endotoxic shock, or bacteremia have been used to study the pathobiology of sepsis, and such models provided useful information regarding the mechanism of cell and organ dysfunctions under those conditions. However, those models do not permit control of the source of infection. • A number of investigators have used cecal ligation and puncture (CLP) in various species to produce polymicrobial sepsis. The CLP model of sepsis mimics many features of clinical peritonitis, including the progressive changes in cardiovascular responses (i.e., an early hyperdynamic phase followed by a late hypodynamic phase). • The CLP model of sepsis is associated with cellular dysfunction (such as hepatocellular depression) and upregulation of proinflammatory cytokines (such as TNF). Furthermore, the ligated and punctured cecum can be excised at various intervals to serve as a source control model of sepsis. Such a model can be used for testing pharmacological agents in the management of sepsis.
