Study Notes
Sterilization Overview
- Complete destruction of microorganisms, including bacterial spores.
- Essential for all Reusable Medical Devices (RMD) to prevent infection.
Ideal Sterilization Methods
- Rapid throughput to ensure efficiency.
- Easily validated to maintain high standards of safety and effectiveness.
- Capable of processing wrapped items, allowing safe storage post-processing without contamination risks.
Common Sterilization Methods
-
Steam Sterilization (Moist Heat)
- Operates under high pressure.
- Cycle time approximately 40–60 minutes.
-
Dry Heat Sterilization
- Functions similarly to an oven, using normal atmospheric pressure.
- Cycle time can extend up to 2 hours.
-
Gas Plasma Sterilization
- Utilizes ambient temperature for effective sterilization.
- Cycle time ranges from 45 to 75 minutes.
-
Ethylene Oxide (EO) Sterilization
- Can occur at sub-atmospheric or high pressure.
-
Low Temperature Steam and Formaldehyde Vapor
- A method that ensures safe processing of sensitive items.
