L'état de choc: Classification et physiopathogénie

The definitions of shock are transposed from human medicine. Shock occurs when a cell is no longer capable of producing the energy required for its metabolism. In terms of pathophysiology, shock is classified as cardiogenic, distributive (or hypovolaemic), hypoxic or cytocellular. This classification describes phenomena that are independent from one another. The situation is more complex when considering the whole body. Septic, traumatic, anaphylactic and thermal shock are combinations of the different types of shock. Shock induces systemic inflammatory response syndrome (SIRS). Initially compensatory mechanisms are put in place, but these are rapidly surpassed and multi-organic dysfunction (MODS) occurs and/or disseminated intravascular coagulation (DIC).
