What is the definition of systemic inflammatory response syndrome (SIRS) and how do you differentiate SIRS from sepsis, severe sepsis, and septic shock?
Which patients presenting with sepsis need admission to the intensive care unit (ICU)?
Which septic patients need invasive monitoring (arterial catheter, central venous catheter)?
What interventions in the treatment of sepsis improve mortality?
Which septic patients deserve empiric steroids as part of the therapeutic regimen?

Sepsis is a clinical syndrome that complicates severe infection and is characterized by systemic inflammation and widespread tissue injury. The incidence and number of sepsis-related deaths has increased from 1979 to 2000, and sepsis remains the tenth most common cause of death in the United States. Despite the rising number of cases, earlier identification of sepsis and improved intensive medical care has been shown to reduce the overall mortality rate to approximately 17.9%. Severity is correlated with mortality; up to 40% of patients with severe sepsis and 60% of patients with septic shock die due to sepsis-related complications (Table 138-1).

Successful shock resuscitation may be associated with considerable morbidity and mortality. Multiple organ dysfunction syndrome (MODS) refers to severe acquired dysfunction of at least two organ systems lasting at least 24 to 48 hours in the setting of sepsis, trauma, burns, or severe inflammatory conditions so that homeostasis cannot be maintained without intervention. Mortality is directly correlated with the number of dysfunctional organs and the duration of dysfunction (Table 138-2). An uncontrolled hyperinflammatory response is believed to be the cause of multiple organ dysfunction.
