[Fluid therapy for acute renal failure].

Acute renal failure (ARF) is a sudden decrease in glomerular filtration rate (GFR) where GFR represents the amount of blood that is filtered by the kidneys. The kidneys are responsible for numerous physiologic processes including excretion of toxic metabolites and maintaining appropriate fluid balance in the body. Thus, ARF can result in a sudden, potentially life-threatening, dysregulation of both of these processes. Inappropriate or inadequate monitoring and therapy for patients with ARF can be lethal.
