According to Schouten et al (2008), sepsis involves the activation of the coagulation cascade coupled with down-regulation of anticoagulation and fibrinolysis. An intricate link between inflammation and coagulation exists within the body (Neligan, 2006). When a pathogen is present in the bloodstream or when tissue injury occurs, an inflammatory response occurs. The response causes a stimulation of the immune system to produce interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis…
