Abstract Objective: The effects of slow diurnal hemodialysis (slow HD) on amino acid losses and nitrogen balance were studied. Design: Slow HD was conducted for 10 h during the day at the dialysate flow rate of 30 ml/min. The patients received total parenteral nutrition including 40 g of amino acids (6.08 g of nitrogen). The amino acid concentrations in plasma and dialysate were determined and the daily nitrogen balance was calculated from the urea nitrogen appearance. Patients: Six critically ill patients with renal failure were entered into the study. Results: Slow HD eliminated 48.5±4.4 mmol (6.2±0.6 g) of amino acids, representing 16% of the daily amino acid load. The estimated nitrogen balance was –2.3±1.3 g/day. Amino acid nitrogen lost in the dialysate was 1.0±0.1 g, contributing 43% of the daily negative nitrogen balance. Conclusion: The amount of amino acid losses during slow HD should be taken into consideration when designing nutritional schedules for maintaining positive nitrogen balance in critically ill patients.
