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?
