Description should include the process for cold sterilization and the following concepts:
- Cold sterilization involves the use of a liquid chemical to sterilize instruments and supplies but can be too corrosive for some items (e.g., scalpels).
- The item must be cleaned before sterilization.
- Disassembly is required of instruments with multiple parts.
- The most common chemical used in cold sterilization is glutaraldehyde, which is not corrosive, but the odor can irritate eyes and mucous membranes, so sterilized items must be washed and thoroughly rinsed with sterile water before being used on patients.
- Glutaraldehyde can be used only with items that can be submerged in liquid (e.g., endoscopes)
- The surgical technologist must verify the inclusion and color change of the chemical indicator.
Process/Skill Questions:
- What are the advantages and disadvantages of using cold sterilization for surgical instruments and supplies?
- What safety precautions should be taken when conducting cold sterilization?
- What factors affect sterilization with glutaraldehyde?
- What types of instruments would be used with the cold sterilization process?
