Sterilization
Firstly, contaminated and soiled instruments are received in the central processing department and taken to the decontamination area. Here, the instruments are manually cleaned to remove gross soils and inspected for any damage. This initial cleaning step is crucial as devices must be fully clean before sterilization. Depending on the instrument and hospital policy, an automated washing process may follow the manual cleaning.
Once the instruments are thoroughly cleaned, they are sent to the preparation and packaging area. This stage involves inspecting, assembling, and packaging the instruments in preparation for final sterilization. The packaging area is separate from the decontamination area to prevent contamination of clean instruments.
The next critical step is sterilization, which utilizes various methods to ensure the instruments are sterile and safe for use. Steam sterilization, or autoclaving, is the predominant form of sterilization. This method uses steam sterilizers or autoclaves, which are suitable for heat and moisture-stable items. Cycle times vary depending on load weight, density, and other factors. Immediate-use steam sterilization cycles (IUSS) are also available for emergency situations, with shorter cycle times ranging from three to ten minutes.
Other sterilization methods include low-temperature sterilization, such as ethylene oxide (EtO), vaporized hydrogen peroxide, liquid chemical sterilization, and ozone sterilization. Each method has unique characteristics and is chosen based on the specific requirements of the instruments. For example, vaporized hydrogen peroxide is commonly used for heat-sensitive devices, while endoscopes may require specialized technology to prevent damage.
After the sterilization cycle, the SPD technician reviews the sterilizer printout to verify if all parameters have been met. Biological and chemical indicators are used to monitor the process and ensure the load achieved sterility. The central processing department may also perform biological testing, where live bacteria is placed with the instruments and incubated to confirm successful sterilization.
Finally, the sterilized instruments are stored in a designated sterile storage area, separate from the decontamination and packaging areas. This separation prevents contamination and ensures the instruments remain sterile until they are distributed for use. The central processing department plays a vital role in hospitals by providing sterilized equipment, maintaining rigorous processes, and upholding patient safety.
