Abstract
A solution for peritoneal dialysis or for infusion comprises two single solutions which, after heat sterilization, are brought together and dispensed, with the first single solution containing calcium ions, additional electrolytic salts and glucose in an osmotically effective concentration and the second single solution containing bicarbonate and a weak acid with pKa<5. To provide a biocompatible solution, in particular for use as a peritoneal dialysis solution, the first single solution is acidified with a physiologically compatible acid to a pH of below 3.2. The second single solution contains bicarbonate only in a proportion which does not exceed 10 mmol/l.
