[Developmental modalities of septic states. Multiple organ failure syndrome].

Sepsis syndrome occurs when an acute infection results in an host generalized inflammatory response including cytokines production. Death is a frequent and unpredictable sequel of this pathological condition. It may be due either to uncontrolled circulatory failure, or to multiple organ failure. With the advent of nitric oxide in the arena of the most potent vasodilatator agents, we now better understand the mechanisms of low vascular resistance during hyperkinetic septic shock. However a closer understanding of the mechanisms of multiple organ failure is actually required to improve survival rates during severe human sepsis.
