Sterilization of instruments and supplies with steam (the primary method for sterilization in the operating room) should include the following:
- Understanding the process of steam sterilization (i.e., destruction of microorganisms using time, temperature, moisture, and pressure)
- Identifying which instruments and supplies can be sterilized with steam (e.g., those not heat-, moisture-, or temperature-sensitive)
- Ensuring that items are cleaned, disinfected, and wrapped before steam sterilization takes place
- Ensuring that time, temperature, moisture, and pressure are carefully controlled and documented during steam sterilization
- Ensuring that steam is able to penetrate the wrapping material
- Verifying the inclusion and color change of the chemical indicator
Demonstration should also include
- an explanation of immediate use steam sterilization (IUSS) (i.e., steaming with the item unwrapped)
- an explanation for when IUSS is done (i.e., in emergency situations, such as when an instrument has been dropped during an emergency procedure).
Process/Skill Questions:
- Why is steam not an option for sterilizing certain surgical instruments and supplies?
- Why must instruments and supplies be clean, disinfected, and wrapped before they are steam sterilized?
- What safety precautions are needed when sterilizing with steam?
- When would one include a biological indicator?
- Why does one have to open/unclamp all surgical instruments?
