Bacterial Contamination of Dialysate: A Surveillance and Investigation

OBJECTIVE To evaluate the cause of unqualified level of bacteria in dialysis fluid and to discover(available) resolution measure to select a batter aseptic sampling manipulation.METHODS Spot sampling in dialysis fluid with two methods A and B was used in a hemodialysis unit,1ml was taken to direct culture,and count the(colony).(RESULTS) The finding showed that the cause of unqualified level of bacteria in dialysis fluid focused in types Ⅲ and Ⅳ of(dialyzable) machine,and the average number of bacteria exceeding standard accounted for 18.48% with method B.CONCLUSIONS The contamination in dialysis fluid is related with dialyzable machine and manned(manipulation).
