Abstract:
Objective:To study the effects of manual inspection and special equipment inspection for light guiding components of hard endoscope after cleaning and disinfection,so as to provide scientific data and evidence for the application of special inspection equipment of hard endoscope in Central Sterile Supply Department(CSSD).Methods:A total of 100 hard endoscopes after cleaning and disinfection,which were in CSSD of the Fifth Medical Center of Chinese PLA General Hospital during July and August 2024,were selected.Each light guiding components of hard endoscope was respectively inspected by manual method and special functional detector for endoscope(inspection method with equipment).The positive rates of fog,stains and glass shards,and overall failure rate of light guiding components of hard endoscope,as well as the difference with the effect of clinical use,between two kinds of inspection methods were compared.Results:In 100 hard endoscopes,the inspection method with equipment found 2 cases were overall failure,which fog,strains and glass shards were respectively 2,0 and 0.The overall failure rate,and the positive rates of fog,stains and glass shards of the inspection method with equipment were respectively 2%,2%,0 and 0,which all lower than overall failure rate(23%),and the positive rates of fog(17%),stains(2%)and glass shards(4%)of manual inspection.There was significant difference in overall failure rate and positive rat of fog between the two kinds of inspection methods(x2=18.286,11.399,P＜0.05).The overall failure rate that was reflected by clinical users was 3%,which was significant lower than 23%of manual inspection,and the difference of that between two methods was significant(x2=15.959,P＜0.05).Conclusion:The inspection for light guiding components of hard endoscopes after cleaning and disinfection can be carried out by manual inspection and special inspection equipment,and results of special inspection equipment is getting closer the usage effect of clinical users.It has a series of advantages include being intuitive,easy use,high accuracy,convenient observation,and archivable.
