Study Notes

Sterilization Definition and Requirements

  • Sterilization is the complete destruction of microorganisms, including bacterial spores.
  • This level of decontamination is required for all reusable invasive medical devices (RMD).

Ideal Sterilization Methods

  • Have rapid throughput
  • Are easily validated
  • Are capable of processing wrapped items to enable storage after processing without the risk of environmental contamination of processed items.

Sterilization Methods

  • Steam (moist heat) at high pressure:
    • Cycle time: approximately 40-60 minutes
  • Dry Heat:
    • Similar to an oven
    • Uses normal pressure
    • Cycle time: up to 2 hours
  • Gas Plasma:
    • At ambient temperature
    • Cycle time: 45-75 minutes
  • Ethylene Oxide (EO):
    • At sub-atmospheric or high pressure
  • Low Temperature Steam and Formaldehyde Vapor:
    • Cycle time: not specified
