Surgical instruments must be carefully sterilized prior to their use in any medical procedure, in order to protect the safety of the patient. However, healthcare professionals realize that sterilization has applications that extend far beyond the operating room.

Autoclaves combine high temperature and high pressure over a period of time to disinfect and sterilize, but it’s a process that must properly executed, every time. It is recommended to monitor three types of indicators to ensure successful sterilization. 

Chemical

The use of chemical indicator tape can help determine whether the autoclave has reached proper sterilization temperature by changing color. However, the use of this indicator alone is not a guarantee that the sterilization cycle was effective.

Mechanical

It’s important to monitor temperature, pressure, and cycle duration when validating or using an autoclave. To accomplish this, technicians typically use high-quality data loggers. In fact, there are data logging systems specifically designed for use in autoclaves that provide reporting tools for easy analysis and recordkeeping.

Biological

Biological indicators, or spore testing, should be conducted on a weekly basis or after when any change occurs to the process (i.e. packaging, repairs, relocation). Spores are more resistant than the microbial contaminants found on instruments, so their destruction is an indicator of a successful sterilization cycle.
