Efficacy of Disinfection of Rigid Endoscope by Ethyl Alcohol 70%

Abstract Introduction Currently, there is no safe, affordable, and ecologically-sustainable guideline that helps prevent contamination through endoscopy. We evaluated the safety of intermediate-level disinfection with 70% ethyl alcohol (w/v) based on biological-load recovery from rigid endoscopes after nasal endoscopy. Objective To demonstrate the efficacy of 70% ethanol in disinfecting rigid endoscopes (REs) to reduce microbial growth in microbiological cultures. Methods After a nasal endoscopy examination, the endoscope was swabbed with gauze; this served as the positive-control sample. T...
