Protein requirement of patients on CAPD: a study on nitrogen balance.

Nitrogen balance studies were performed in 8 patients undergoing CAPD. Patients were studied in a metabolic ward for 14 days while eating a diet providing 1.2 g/kg B.W. of proteins and supplying 166-188 KG/Kg. From these studies it is concluded that 1.2 g/Kg are a safe intake for patients on CAPD. Nevertheless it is strongly suggested that patients on CAPD should undergo a nitrogen balance study in order to ascertain whether such a diet is safe or should be modified for energy and/or protein supply.
