Abstract:  Objective to reduce dialysate microbial contamination, and improve the quality of dialysate, ensure the safety of patients with dialysis. Methods Compared to dissolve powder concentrate after single B for the use of liquid for liquid concentrate, and online Bibag powder by three different ways of B concentrate configuration differences in microbial content in the preparation of dialysis fluid. Result Three B preparation of dialysis fluid concentrate configuration method in the microbial content have significant differences, which use the online Bibag dialysate endotoxin content in the dry powder preparation is less than that of other two methods. Conclusion using on line Bibag can improve the quality of dialysate
