Autoclaving liquids presents some unique challenges. Sterilization cycles for liquid loads take a longer time to complete since liquids have a high heat capacity. As opposed to solids, liquids take a lot longer to heat up and cool down, and the total cycle time is increased dramatically as a result. When autoclaving liquids, certain cycle features can be incorporated into the sterilization process to optimize its efficiency and sterilization effectiveness.
Introduction:
The CSSD, the Central Sterile Services Department, is the hospital’s central nervous system, where the battle against infection takes place. Here surgical instruments are readied for reuse after being decontaminated or sterilized (depending on usage and risk level).
The decontamination cycle demonstrates strict and standardized cleaning, disinfection and sterilization processes that surgical instruments go through before they can be reused. Washer disinfectors perform the automated cleaning and disinfection process before instruments undergo the final sterilization process.
Cleaning and Disinfection Process:
The first stage of washer disinfectors cycle involves a pre-wash where cold water is introduced and circulated within the chamber. This initial process removes any loose or thick soiling and debris present on the instruments.
After which, liquid detergent is dispensed into the chamber to facilitate the cleaning and removal of any further contamination present. Detergents used should be verified by the manufacturer to be suitable for use with the machine. They should also be compatible with the reprocessed instruments to avoid degradation, discoloration and other damages.
Rinsing cycles are then performed with hot or cold soft water to remove the cleaning agent residues from the load.
The load then undergoes a thermal disinfection cycle using water held at a specified temperature (above 90°C) and time period. The high temperature helps to kill or inactivate most microorganisms though it must be noted that this process does not eliminate the need of the final sterilization step.
For the final stage, pre-filtered hot air is introduced and circulated within the chamber to remove moisture from the instruments. Tuttnauer Washers use a pre-filter and HEPA H14 Filter to remove particulates from the air before it enters the chamber.
Advantages of using Washer Disinfectors:
Using Washer Disinfectors, the parameters are standardized for each wash cycle. Surgical instruments will undergo the exact same cycle each time, ensuring a standardized cleaning and disinfection process for surgical instruments.
In Washer Disinfectors, the wash process is constantly monitored by the machine’s control system. The machine ensures that the cleaning is validated at the end of the cycle for each load. A record of the cleaning cycles is stored by the washer and can be printed out, ensuring traceability of the process.
The staff are protected from the high temperatures and chemicals used in the cleaning and disinfection cycles, because the process is fully automated and the need for manual intervention is eliminated.
Automation of the cleaning process translates into cost and time savings for the facility, allowing the staff to focus on other areas of work.
