Study Notes
Disinfection Processes
- Thermal Disinfection: Utilizes heat to eliminate microorganisms excluding spores.
- Sterilization: Complete destruction of all forms of microorganisms.
Types of Disinfectants
- Antiseptics: Chemicals that slow down microorganism growth on living tissues.
- Iodophors: Belong to the halogen disinfectant family.
- Phenolics: Classified as intermediate to low-level disinfectants.
- High-Level Disinfectants: Include Glutaraldehyde and OPA.
Classification of Items
- Critical Items: Directly introduced into the bloodstream or sterile body areas.
- Non-critical and Semi-critical Items: Require different levels of disinfection based on their use.
Disinfection Procedures
- Mechanical Cleaning: Items must be cleaned prior to sterilization; this is false for disinfection.
- Contact Time for Alcohol: Requires a minimum of 5 minutes to ensure reasonable disinfection.
- Thermal Disinfection Method: Accomplished using heated water.
Chemical Disinfectant Characteristics
- Regulation of Washers: Mechanical washers and washer-decontaminators are not regulated by the CDC.
- Liquid Disinfectants: Not all can achieve sterilization even with extended exposure time.
Record Keeping
- Logbooks: Must be maintained for the use of Glutaraldehyde and OPA for traceability and safety measures.
- Sterilant and High-Level Disinfectant Timing: Time to achieve sterilization is longer than for high-level disinfection.
