Sterile Instruments

At Dr.Khan’s office we strive to maintain a clean and sterile surgical environment. We have implemented the following three modalities to monitor and maintain sterile instruments:


At Dr. Khan’s office, we use the latest and most effective sterilization equipment.
Mechanical indicators such as temperature and pressure gauges provide valuable information even before the load is removed from the sterilizer chamber. Although sterilizer printouts or temperature readings may indicate adequate parameters, they may not reflect conditions inside individual packs within the sterilizer.


Chemical monitoring is used to evaluate conditions inside the sterilizer and within individual packages. We place chemical indicators inside all sterilization packages. If the expected change in chemicals does not occur, it may indicate equipment malfunction or procedural errors such as overloading. In this case, we repackage and resterilize the instruments.


Because there is no means of actually testing whether all microbes on all instruments in a load are killed during sterilization, the next best thing is to determine if the sterilization procedure can kill a known population of highly resistant bacterial spores. In compliance with the ADA, CDC and Organization for Safety and Asepsis Procedures all agree that biological spore testing should be done at least once per week.

At Dr. Khan’s office we do weekly spore testing and we use North Bay Bioscience, one of the largest sterilizer monitoring services in the country.

These are some of the ways to put our patients first
by assuring their safety.
