    Study Notes

    Instruments Processing Methods

    • Instrument Classification - Critical, semicritical, noncritical
    • PPE - Eye protection, gloves, mask, protective clothing
    • Workflow Pattern - Linear or semicircular without doubling back
    • Holding Solution - Used for instruments awaiting processing. Prevents drying of blood and debris.
    • Pre-Cleaning Methods - Ultrasonic cleaning, thermal washing/disinfecting
    • Ultrasonic Cleaner - Uses sound waves to create bubbles and dislodge debris
    • Kitchen Dishwashers - Not FDA-approved for instrument cleaning
    • Instrument Rusting Prevention - Sodium nitrate rust inhibitors or thorough drying
    • Packaging Before Sterilization - Ensures sterility maintenance
    • Never Use Pins, Staples, or Paper Clips - Can puncture packaging, compromising sterility

    Sterilization Methods

    • Heat Sterilization - Steam, chemical vapor, dry heat
    • Flash Sterilization Disadvantage - Unpackaged, becomes non-sterile after removal
    • Chemical Vapor Sterilization Advantage - Preserves instruments, prevents rusting and dulling
    • Dry Heat Sterilization Types - Static air and forced air
    • Liquid Chemical Sterilization Disadvantage - Inhibits biological monitoring
    • Liquid Chemical Sterilization Rinse - Sterile water rinse for sterility maintenance
    • Sterilization Failure Cause - Inadequate exposure to sterilizing agent

    Sterilization Monitoring

    • Sterilization Monitoring Forms - Physical, chemical, biological
    • Process Indicator - Placed externally on packs to show exposure to heat
    • Process Integrator - Placed internally on packs to show exposure to heat, temperature, and pressure
    • Process Indicators and Integrators Do Not Ensure Sterility - Biologic monitoring is necessary
    • Biological Monitoring - Determines the effectiveness of sterilization
    • High-Speed Handpiece Processing - Flush before sterilization
    • High-Speed Handpiece Sterilization Methods - Only steam and chemical vapor
    • Event-Related Packaging - Sterility assumed indefinitely unless contamination occurs
    • Clean Supplies and Instruments Storage - Closed or covered cabinets preferred
