PROTEIN REQUIREMENTS IN RENAL FAILURE
Protein requirements for patients with renal failure are dependent on the acute or chronic nature of renal failure and the presence and type of dialysis. The nutritional status and adequacy of current intake of patient should be considered.
Haemo- and peritoneal dialysis patients require a higher amount of proteins than healthy adults. The National Kidney Foundations US recommends 1.2 g protein/kg/day for stable maintenance haemodialysis patients, and 1.2-1.3gms protein/kg/day for stable peritoneal dialysis patients. See Table below for protein recommendations in renal failure:
