Which sterilization method is considered a last resort?

Immediate use steam sterilization is often viewed as a last resort because it is typically reserved for situations where surgical instruments are needed urgently and do not have time to undergo standard sterilization cycles. This method is applied to items that have been cleaned and must be sterilized quickly, often in situations where there may not be enough time to perform an adequate cleaning or sterilization process according to the preferred methods.

In contrast, other sterilization methods, such as ethylene oxide, hydrogen peroxide plasma, and dry heat sterilization, are planned and used under specific protocols to ensure the highest level of sterility. These methods usually require more time and sometimes specific environmental conditions to achieve effective sterilization. Thus, they are preferred in routine situations over immediate use steam sterilization, which should be a contingency for urgent needs.
