Instrumentdesinfektionsmedel

Instrumentdesinfektionsmedel are chemical agents used to reduce or inactivate microorganisms on reusable medical and laboratory instruments. The term is used in some Scandinavian languages and translates roughly to instrument disinfection agents. They are applied in reprocessing workflows after initial cleaning, and are chosen based on the level of disinfection required and the device’s material compatibility. High‑level disinfectants are used for heat‑sensitive instruments when sterilization is not feasible, while sterilants are used when complete microbial elimination is necessary.

Common classes of instrumentdesinfektionsmedel include aldehydes (such as glutaraldehyde and ortho-phthalaldehyde), oxidizing agents (peracetic acid and hydrogen peroxide-based formulations), and chlorine‑ or quaternary ammonium compound–based products. Enzymatic cleaners and surfactants are often used prior to disinfection to remove organic matter and improve contact between the disinfectant and the instrument surfaces. The choice of agent depends on the device, the required disinfection level, laboratory or clinical setting, and local regulations.

Disinfection effectiveness depends on proper contact time, concentration, temperature (where specified), and complete coverage of all instrument surfaces. Many agents can corrode metals or damage delicate plastics, so manufacturers’ instructions must be followed. Regular validation, adherence to regulatory standards, and staff training are essential to ensure safety and efficacy. After use, instruments should be thoroughly rinsed if required, dried, and stored according to facility protocols. Environmental and waste considerations include proper disposal of hazardous chemicals and compliance with local environmental regulations.
