Effectiveness of different cleaning agents on overnight rigid endoscopic instruments
OBJECTIVE To evaluate the cleaning effect of different cleaning agents on overnight rigid endoscope cleaning.METHOD From Jul.to Dec.2023,320 sets of endoscopic instruments were divided into groups,each group had 80 sets of endoscopic instruments of the same structure and similar models,and the overnight endo-scopic instruments were treated with cleaning agents of different compositions,such as multi-enzyme cleaning so-lution,alkaline cleaning solution,moisturizing gel cleaning agent,foaming moisturizer,etc.,and the differences among the groups were evaluated by visual inspection method,adenosine triphosphate(ATP)fluorescence detec-tion method and luminal instrument detection workstation(50× magnifying glass with light source).RESULTS In the process of cleaning endoscopic instruments,the three cleaning methods of visual inspection method,ATP fluo-rescence detection method and lumen instrument detection workstation were used for test of the endoscopic instru-ments,the qualified rate of endoscopic surface cleaning effect in the foam humectant group was 88.75％,86.25％and 83.75％,respectively,and the qualified rate of lumen inner wall cleaning was 87.50％,85.00％and 81.25％,respectively,and the cleaning pass rates of the other three groups were below 80.00％.CONCLUSION Of the four cleaning agents,the foam type of cleaning agent had the highest pass rate for overnight rigid endoscop-ic instrument cleaning.
