Study Notes
Overview of Sterilization
- Complete destruction of microorganisms, including bacterial spores.
- Essential for all reusable invasive medical devices (RMD).
Ideal Characteristics of Sterilization Methods
- Rapid throughput for efficiency.
- Easy validation to ensure effectiveness.
- Ability to process wrapped items for safe storage without contamination risk.
Common Sterilization Methods
-
Steam (Moist Heat)
- Operates at high pressure.
- Cycle time: approximately 40–60 minutes.
-
Dry Heat
- Functions like an oven at normal pressure.
- Cycle time: up to 2 hours.
-
Gas Plasma
- Works at ambient temperature.
- Cycle time: 45–75 minutes.
-
Ethylene Oxide (EO)
- Can be performed at sub-atmospheric or high pressure.
-
Low Temperature Steam and Formaldehyde Vapor
- Specific cycle time not provided; typically used for heat-sensitive items.
