Sepsis and septic shock represent a significant healthcare burden. The incidence of sepsis has increased in recent decades, affecting over 660,000 people in 2000. Sepsis progresses along a continuum from systemic inflammatory response syndrome to severe sepsis to septic shock. Common sites of infection include the lungs, abdomen, and urinary tract, while common pathogens are gram-positive bacteria, gram-negative bacteria, and fungi. Early goal-directed therapy within 6 hours improves outcomes by optimizing oxygen delivery through fluid administration, vasopressors, inotropes, and blood transfusions.
