[Bicarbonate hemodialysis in the therapy of chronic kidney failure]

A method of random sampling was applied to 10 CRI patients to analyze the results of 24 hemodialyses with acetate solution for dialysis (35 mmol/l) and 34 hemodialyses with bicarbonate solution for dialysis (35 mmol/l). Significant reduction of complications like headache, nausea, vomiting, tachycardia, dyspnea, extrasystole was observed in bicarbonate dialysis. The concentration of mean molecular uremic toxins was decreased from 5.75 +/- 0.84 mmol/l in acetate dialysis up to 2.63 +/- 0.21 mmol/l in bicarbonate dialysis. The content of intracellular potassium returned to normal. The concentration of serum cholesterol was decreased from 5.6 +/- 0.4 up to 4.8 +/- 0.2 mmol/l. These data indicated a favorable effect of bicarbonate dialysis on intracellular metabolism. Preliminary data did not confirm the normalizing effect of bicarbonate dialysis on the development of uremic osteopathy.
