Abstract
Substituting bicarbonate by acetate in dialysis fluids has been proposed for avoiding precipitation of calcium and magnesium carbonates. However, acetate hemodialysis has been abandoned because of deleterious effects of acetate. Conventional bicarbonate hemodialysis is not totally acetate-free, because 3 to 7 mEq/l of acetic acid are added to the dialysate. Acetate-free hemodialysis is possible with another acid (chlorhydric acid or citric acid) or without acid by using some techniques of low-efficiency hemodiafiltration, as acetate-free biofiltration, which avoids the deleterious effect of blood acidification into the dialyzer. In this paper, advantages and disadvantages of different techniques of acetate-free hemodialysis are discussed.
