Evaluation of application effect of different drying and storage methods of endoscope
Objective To evaluate the effects of different drying and storage methods on flexible endoscopy,and to provide reference for clinical selection of appropriate drying and storage methods.Methods A total of 112 endoscopes were selected by convenient sampling method.After standardized reprocessing steps,the endoscopes were randomly divided into two groups,air gun purging group and ethanol perfusion air gun purging group.The endoscopes were dried for 0.5,1,3,5 min respectively,and then placed in automatic cabinets and standard cabinets,and stored for 0,3,12,24,48,72 and 168 h.The qualified condition of endoscope lumen drying was observed by cobalt chloride test paper,and the qualified condition of endoscope disinfection was observed by microbiological monitoring.Results The two groups could not remove all the residual liquid in the endoscope lumen after the endoscope was dried for different time.There was still liquid residue after the endoscope was dried for 0.5 min and stored in the standard cabinet for 168 h.There was no liquid residue after the endoscope was stored in the automatic cabinet for 3 h.Two groups showed positive microbial results after 24 h storage in the standard cabinet,and the positive microbial detection rate after 72 h storage in the automatic cabinet was 0%,and the positive detection rate of the ethanol perfusion air gun purging group was 0%after 168 h storage in the automatic cabinet.Logistic regression analysis showed that alcohol injection air gun purging and drying,automatic cabinet storage and prolonged drying time were protective factors for endoscope disinfection effect.Conclusion Automatic drying storage cabinet can increase the safety of endoscope storage.
