Nutritional management of catabolic acute renal failure requiring renal replacement therapy

Catabolic acute renal failure patients have a high incidence of morbidity and mortality despite advances in dialytic and lifesaving technologies. Malnutrition is a complicating factor in the treatment of these patients. Early and aggressive nutritional support may positively impact eventual outcome. Continuous renal replacement therapy (CRRT) enables delivery of this support. This article reviews nutritional support in acute renal failure for individuals undergoing these therapies.
