We have devised recently a new bicarbonate dialysate supply system, which we call “Bicarbonate Infuser (B. I.)”. B. I. was composed of a simple proportioning bicarbonate infusion unit connected to the usual single-pass dialysate supplyer. This small machine (16×30×20cm.) was able to prepare dialysate with stable electrolyte composition. We had clinical experences with B. I. in 7 uremic patients for about 6 month, and were successful for prevention of the dialysis disequilibrium syndrome and the symptom derived from acetate intolerance.
