The Protein Equivalent of Nitrogen Appearance in Critically Ill Acute Renal Failure Patients Undergoing Continuous Renal Replacement Therapy

Malnutrition was uncommon in patients with acute renal failure at the time of initiation on CRRT, but their total body water was increased. They exhibited hypercatabolism and the mean normalized PNA was 1.57 g/kg/day. A large negative nitrogen balance was observed in them, since their protein intake was suboptimal.
