Sterilization and Patient Safety

Our office uses state of the art sterilization to ensure patient safety. Sterilization and disinfection are the basic steps in instrument processing and surface asepsis. Sterilization refers to the use of a physical or chemical procedure to destroy all forms of microorganisms, including the highly resistant spores.

We use Rapid Steam Autoclave at 275º F(35psi), for 15-20 minutes.

We use Biological, Chemical and Mechanical indicators to monitor our sterilization process.

Using bacterial spores to monitor the sterilization process is referred to as biologic monitoring (or spore-testing), and the bacterial spores used for monitoring the sterilization process are referred to as biologic indicators (BIs). Of the three methods, biologic monitoring is regarded as the most valid for monitoring the sterilization process, for it uses live, highly resistant bacterial spores.

We biologically monitor our sterilizer once a week to ensure complete sterilization using spore strips and keep accurate records for our monitoring. These strips are enclosed in a glassine envelope and processed through the sterilizer. They are then sent to our spore testing center where they are tested for live spores.

Chemical monitoring involves using chemical indicators (CIs) that change color or form when exposed to specific high temperatures or to the sterilizing conditions within a sterilizer. This is referred to as chemical monitoring (or process monitoring). We use sterilization pouches that have special marking that change color when subjected to sterilizing temperatures.

Mechanical monitoring involves observing and recording the physical aspects (e.g., temperature, pressure, or time) of the cycle when the sterilizer is being operated. Our sterilizer is serviced regularly to ensure proper functioning.
