| [ Summary ] |
Methods for washing and disinfecting lines through which the dialysate flows have changed as progress has been made on blood purification therapy. There are many washing and disinfecting chemicals. There concentrations and use should be for adequate amount of time and should be precisely determined with understanding of their properties such as the scaling effects of biofilm and the erosion of hemodialysis equipment produced by those liquids. In our clinic we usually use a 0.6% acetic acid solution and a 0.12% sodium hypochlorite solution for washing and disinfection of endotoxin removing filters, and obtain good results on endotoxin values. The result appears to depend on the use of endotoxin removing filters. The content of particles obtained after filtering was greatly lowered, even when a set of in-line monitors measuring amounts of particles was put on before or after the filter. However, we should not overestimate the effects of endotoxin reducing filters but pay careful attention to the washing and disinfection of lines through which the dialysate flows. |
