[Clinical research of dialyzer reprocessing machine W-F168-B]

This is a research project aimed at investigating the clinical efficiency of W-F168-B, a dialyzer reprocessing machine made by Weilisheng Biological Material Company in Chengdu, evaluating its effects on total cell volume (TCV) and dialysis sufficiency, and assessing its disinfection efficacy. All subjects were randomly divided into two groups, whose dialyzers were reprocessed by W-F168-B (made in Chengdu) and RENATRON II (made by MINNTECH Company in the United States) respectively. We detected TCV of the dialyzer before and after reusing and calculated their diversity. We also calculated all subjects' Kt/V. The values of TCV diversities of two groups were 5.5 +/- 4.15 (experimental group) and 4.5 +/- 2.56 (control group) respectively, P > 0.05. The levels of Kt/V of experimental group and control group were 1.25 +/- 0.26 and 1.24 +/- 0.19, P > 0.05. T-test showed that there was no statistically significance difference between the two groups. The result of every hemoculture is negative. In conclusion, these two dialyzer reprocessing machines are similar in the effect of the dialyzer's performance and the subject's dialysis sufficiency. The reused dialyzers reprocessed by these two machines are safe for use.
