Study Notes
Disinfection Agents and Practices
- Quaternary ammonium compounds are low-level disinfectants incompatible with soap.
- Glutaraldehyde does not require latex gloves for protection; this statement is false.
- High-level disinfectants are particularly susceptible to deactivation by organic matter.
Key Sources of Disinfection
- In automated washers, water temperature plays a crucial role in disinfection effectiveness.
- Test strips are essential for verifying the minimum effective concentration of high-level disinfection solutions each time the solution is utilized.
Disinfection and Sterilization Definitions
- Thermal disinfection uses heat to eliminate all microorganisms except spores.
- Antiseptics are chemicals applied to living tissue to inhibit microorganism growth.
- Critical items refer to those introduced into sterile areas or the bloodstream, necessitating stringent sterilization protocols.
- Sterilization is the complete eradication of all microorganisms.
Chemical Classifications
- Iodophors belong to the halogen family of disinfectants.
- Phenolics are categorized as intermediate to low-level disinfectants.
- High-level disinfectants include glutaraldehyde and ortho-phthalaldehydes, which are preferred for instrument disinfection.
Application and Effectiveness
- Thermal disinfection is solely achieved through the application of heat.
- Alcohol requires prolonged wet contact of 5-10 minutes to attain effective disinfection levels.
- Ortho-phthalaldehydes are recommended as the optimal choice for high-level disinfection of instruments.
