Surface Cleaning and Disinfection
of Anesthesia Devices
The cleaning and disinfection of anesthesia device surfaces are essential for infection prevention
and are a critical process to ensure patient safety.
Cleaning
The initial step removes organic matter, inorganic debris, and contaminants from equipment surfaces, reducing conditions for microbial growth.
This step improves the effectiveness of disinfectants and is performed mechanically using soap or detergents at different pH levels.
Afterward, residues must be thoroughly rinsed off and the equipment fully dried.
Disinfection
A process performed after cleaning to reduce harmful microorganisms on equipment surfaces.
Chemical or thermal methods are chosen based on device features and disinfectant type, using only validated approaches.
Registered products must be used exactly as specified in the manufacturer’s instructions.
Sterilization
A procedure that thoroughly kills all microorganisms, including spores.
It is most effective when performed after the removal of organic material and pathogens.
Common methods include physical techniques (e.g., steam) and chemical processes (e.g., ethylene oxide gas).
