Acute renal failure in the intensive care unit - Therapy overview, patient risk stratification, complications of renal replacement, and special circumstances

This article provides a basic definition of severity scoring among patients with acute renal failure and extends the definition into the types of dialysis support that are generally used in intensive care unit acute renal failure. Acute dialysis dosing and the problems that create a difference between chronic renal failure and acute renal failure support are described, the dialytic techniques and side effects and complications of each are compared, and nonrenal-based special situations in which extracorporeal therapy has been found to be helpful are defined.
