Abstract
The present invention relates to dialysis solutions for peritoneal dialysis, containing hydroxyethyl starch as the osmotically-active substance, electrolytes and, optionally, conventional additives, where the hydroxyethyl starch has a molecular weight Mw in the range from 10,000 to 150,000, a substitution MS in the range from 0.10 to 0.40, a substitution DS in the range from 0.09 to 0.35 and a substitution ratio C2/C6≧8. With this peritoneal dialysis solution it is possible, with an outstanding ultrafiltration, to maintain a longer dwell time, for example the dialysis solution can be utilized for a period of 12 hours in the CAPD without replacement. In addition, the inventive dialysis solution is also particularly advantageous for patients with residual kidney function. The resorption of the osmotically active substance is clearly diminished and even after a dwell time of 12 hours it amounts to a maximum of 60-70%.
