Removing of pathogenic organisms from reprocessed surgical devices is crucial to forestall iatrogenic infections. Some micro organism could make persistent biofilms on medical gadgets. Contamination of non-disposable gear with prions additionally represents a critical danger to surgical sufferers. Environment friendly disinfection of prions from endoscopes and different devices reminiscent of high-resolution cameras stays problematic as a result of these devices don’t tolerate aggressive chemical or warmth remedies. Herein, we develop a brand new washing system that makes use of each the alkaline and acidic water produced by electrolysis. Electrolyzed acidic water, containing HCl and HOCl as energetic substances, has been reported to be an efficient disinfectant. A zero.15% NaCl resolution was electrolyzed and used instantly to clean bio-contaminated chrome steel mannequin programs with alkaline water (pH 11.9) with sonication, after which with acidic water (pH 2.7) with out sonication. Two bacterial species (Staphylococcus aureus and Pseudomonas aeruginosa) and a fungus (Candida albicans) had been successfully eliminated or inactivated by the washing course of. As well as, this course of successfully eliminated or inactivated prions from the chrome steel surfaces. This washing system might be doubtlessly helpful for the disinfection of scientific gadgets reminiscent of neuroendoscopes as a result of electrolyzed water is light to each sufferers and gear and is environmentally sound.
