Study Notes
Cleaning and Disinfecting Overview
- Some disinfectants can be caustic and toxic to tissues; proper use is necessary.
- Nurses must always read labels and follow manufacturer's recommendations for disinfectant use.
Sterilization Defined
- Sterilization is the complete destruction of all microorganisms, including spores.
- Common sterilizing agents include steam under pressure, ethylene oxide gas, hydrogen peroxide plasma, and certain chemicals.
- Thorough cleaning of items is essential prior to sterilization.
Categories of Cleaning, Disinfecting, and Sterilizing
- Medical devices are classified into three categories based on their intended use and level of risk.
- Familiarity with agency policies and procedures for cleaning and handling care items is crucial for nurses.
- Most disinfection and sterilization procedures are performed by specially trained personnel.
Factors Affecting Disinfecting and Sterilizing Efficacy
- Concentration of solution and duration of contact: Weakened solutions or short exposure times reduce effectiveness.
- Type and number of pathogens: Some organisms are easier to eliminate; higher pathogen loads require longer disinfecting times.
- Surface areas: All contaminated surfaces must be completely exposed to disinfecting agents.
- Temperature: Disinfectants generally work more effectively at room temperature.
- Presence of soap: Soap may render certain disinfectants ineffective; thorough rinsing is necessary before use.
- Organic materials: Disinfectants can lose efficacy if blood, saliva, or other bodily fluids are not cleaned off first.
Method Selection for Disinfection and Sterilization
- Choosing the appropriate method hinges on the intended use and nature of the item.
- Delicate instruments might require gas or plasma sterilization instead of steam due to their sensitivity.
