DISINFECTION OF REGENERATED DIALYZERS WITH OZONE

Regenerated, ozone-disinfected dialyzers were use for a total of 190 hemodialyses in 35 patients without the occurence of any complication or pyrogen reactions, the efficiency of hemodialysis was identical with that of new or formalin-disinfected dialyzers. The priming fluid contained in both compartments of ozone-disinfected dialyzers proved to be sterile. The ozone did not damage the dialyzer membrane or the supporting structure of dialyzer. Ozone can effectively substitute formalin and other chemical sterilants as a disinfectant of regenerated capillary dialyzers. The process can also be automated.
