This document discusses acute renal failure in patients with sepsis. It defines sepsis and the RIFLE classification system for acute renal failure. It then covers the pathophysiology of how sepsis can lead to acute renal failure, including arterial vasodilation, hemodynamics, hormones, and effects on Starling forces. Early fluid resuscitation, glucose control, glucocorticoids, and renal replacement therapy are presented as beneficial interventions for patients with sepsis and acute renal failure based on clinical studies.
