Study Notes

Sterilization

Essential for critical items that come into contact with sterile tissues or the vascular system to prevent infections.
Requires strict adherence to sterilization methods to ensure safety.

Sterilization Methods

Varied methods exist to suit different equipment and instruments used in healthcare settings.

Sterilization by Heat

Involves the application of heat to eliminate all forms of microbial life.
Effective for items that can withstand high temperatures and moisture.

Dry Heat Sterilization

Utilizes a hot air oven to sterilize glassware and other moisture-resistant items.
Suitable for objects that can tolerate dry heat without damage.

Moist Heat Sterilization

Achieved through steam sterilization, typically involving temperatures above 100°C.
Effective for reprocessing thermolabile (heat-sensitive) items.

Specific Applications

Dry heat is ideal for sterilizing air filters and large volumes of air.
Moist heat sterilization is appropriate for heat-sensitive liquids, such as intravenous (IV) solutions.

Disadvantages

Some methods, like dry heat, require items to be both heat and moisture resistant.
Not all instruments can withstand the harsh conditions of heat sterilization.
