daily room disinfection

Experimental group

Description:

Room disinfection was defined as the cleansing and disinfection of the surface of the facility, endoscopist's gown, and air in the endoscopy room after the examination. Specifically, sanitizing wipes wiped the surface of the facility one by one, containing quaternary ammonium salt, alcohol, and interfacial activator; the air disinfection machine continued for 30min of air disinfection. Daily room disinfection was defined as disinfection after completing 8 non-general anesthesia gastroscopy or 4 general anesthesia gastroscopy.
