Systemic inflammatory response syndrome: septic shock.

The systemic inflammatory response syndrome (SIRS) is the body's response to a multitude of chemical mediators. Conditions inciting the release of these mediators include bacterial sepsis, viremia, pancreatitis, trauma, neoplasia, heat stroke, and many others. The key to the successful management of SIRS lies in anticipation and not reaction. Resuscitation of the patient to supranormal levels, coupled with aggressive monitoring and support of target organs are essential.
