Study Notes
Definition and Purpose
- Low-temperature sterilization refers to the process of sterilizing medical instruments and equipment using methods that do not involve high temperatures.
- The purpose is to sterilize heat-sensitive instruments that would be damaged or destroyed by high temperatures.
Methods
-
Ethylene Oxide Sterilization:
- Uses a gas to sterilize instruments
- Effective against all types of microorganisms
- Commonly used for heat-sensitive instruments and plastics
-
Hydrogen Peroxide Gas Plasma Sterilization:
- Uses a gas plasma to sterilize instruments
- Effective against all types of microorganisms
- Low toxicity and environmentally friendly
-
Ozone Gas Sterilization:
- Uses ozone gas to sterilize instruments
- Effective against bacteria, viruses, and fungi
- Environmentally friendly and low toxicity
-
Filtration Sterilization:
- Uses filters to remove microorganisms from liquids
- Effective for sterilizing liquids and gases
- Commonly used in pharmaceutical and biotechnology industries
-
Lyophilization Sterilization:
- Uses freeze-drying to sterilize instruments
- Effective for heat-sensitive instruments
- Commonly used for pharmaceutical and biotechnology applications
Advantages and Limitations
-
Advantages:
