Abstract:
Objective To investigate the current status of cleaning and disinfection of endoscopic ultrasound micro-probes in tertiary hospitals in Beijing.Methods 51 tertiary hospitals in Beijing were selected with convenience sam-pling method,and a questionnaire survey was conducted on head nurses in endoscopy centers,the investigation in-cluded pre-treatment,cleaning,disinfection,sterilization,biological testing,disinfection traceability,storage and maintenance of endoscopic ultrasound microprobes.Results Among the 51 tertiary hospitals,33 were first-class hospitals and 18 were second-class hospitals.76.47％(n=39)of hospitals performed bed-side pre-cleaning on ultrasound microprobes after use,bed-side pre-treatment methods for endoscopic ultrasound microprobes mainly included enzyme solution wiping(38.47％,15/39)and ethanol wiping(30.77％,12/39);96.08％(n=49)of hospitals performed manual cleaning for ultrasound microprobes,with"enzyme wash-scrub-dry"as the main method(58.82％,n=30);96.08％(n=49)of hospitals disinfected microprobes after use,with chemical disinfectant im-mersion as the main methods(65.31％,n=32);43.14％(n=22)of hospitals sterilized the microprobes,and the main method of sterilization was immersion in 0.2％-0.35％peroxyacetic acid for 10-15 minutes(77.27％,17/22);41.18％(n=21)of hospitals regularly conducted biological monitoring on microprobes;37.25％(n=19)of hospitals traced the cleaning and disinfection process of microprobes;88.24％(n=45)of hospitals regularly inspec-ted,maintained,and repaired microprobes.Conclusion The pre-treatment,cleaning,disinfection,sterilization,and biological monitoring of endoscopic ultrasound microprobes in 51 tertiary hospitals in Beijing varies significantly,and it is recommended that a relevant expert consensus or guideline be formulated as early as possible,so as to standardize the cleaning and disinfection of endoscopic ultrasound microprobes.
