Acute Kidney Injury

Abrupt decline in kidney function over hours to days, evidenced by rising creatinine or decreased urine output.

Also: AKI, Acute Renal Failure

Categorized as prerenal (volume depletion, hypotension), intrinsic (acute tubular necrosis, glomerulonephritis), or postrenal (obstruction). Nutrition support depends on RRT modality: patients on continuous renal replacement therapy lose amino acids, water-soluble vitamins, and trace elements and require liberal protein (1.5 to 2.5 g/kg/day) plus replacement of those losses.
