Abstract:
Objective To investigate the cleaning effects of two different methods (modified ultrasound method VS traditional cleaning method) on endoscopy buttons,including suction button and water/gas injection button,and to provide effective clinical evidence for seeking better methods in cleaning endoscopy buttons.Methods A total of 200 endoscopy buttons were randomly divided into two groups:modified ultrasound cleaning group (experimental group) and traditional cleaning group (control group).The combination of multienzyme abluent and ultrasound vibration was applied to the experimental group and multienzyme abluent was used in the control group.ATP bioluminescence detection technology was applied to detect the residual status of organic substance and this parameter was used to evaluate the disinfection status of two different cleaning methods.Results The average organic substance residual was (217.0 ± 29.8) RLU and (42.74 ±8.6)RLU in control group and experimental group,respectively(P ＜0.01).The pass rates were 26％ (26/100) and 87％ (87/100) in in control group and experimental group respectively (P ＜ 0.01).Conclusion Modified ultrasound cleaning method combined with multienzyme abluent and ultrasound vibration has great cleaning effects on endoscopy buttons before disinfection.It can be regarded as a new method for cleaning endoscopy buttons.
