Abstract

In laboratory testing, a novel hydrogen peroxide gas plasma endoscope sterilizer consistently reduced vegetative organisms, but not bacterial spores, to undetectable levels in the presence of high organism load (≥6.5 log10) and organic material and salts. These findings highlight the importance of meticulous cleaning of endoscopes prior to sterilization.
