Disinfection in Gastrointestinal (GI) endoscopy is a fairly modern and interesting procedure in India. Dr KL Goh, professor and expert, University of Malaya, Kuala Lumpur, Malaysia, conducted a lecture regarding the same.
Dr Goh, briefed about the endoscope general principles applying to all levels of resources.
Speaking about the pre-cleaning of endoscope he said, ” Clear gross debris by sucking detergent through the working channel (250ml/ min). Ensure the working channel is not blocked and wipe down the insertion shaft. Transfer the endoscope to a reprocessing room with atmospheric extraction facilities.”
He added, ” Detergents with or without enzymes, and detergents containing antimicrobial substances can be used for cleaning of the endoscope. Clean the external surfaces of the endoscope with a soft cloth, sponge or brush.”
For the staff protection, he said, “Use long-sleeved waterproof gowns, which are changed between patients. Gloves long enough to cover the arms. Rooms with appropriate ventilation and air exchange of use with disinfection agents.”
As per Dr Goh, endoscope sterilisation can be done by steaming under pressure, dry heat, hydrogen peroxide, gas plasma and liquid chemicals.”
