Ultrasonic surgical instrument Cleaner Treatment

Studies demonstrate that Washer Disinfectors with Ultrasonic surgical instrument Cleaner Solution Treatments deliver optimal cleaning using a 'combination' mechanical and chemical "Proper Sequence of Treatments". After surgical instruments were cleaned in Washer Disinfectors with Ultrasonic Cleaner Solution Treatment, a 4 enzyme detergent: "the efficacy of disinfection was 100%", "removed all pathogens", and "All instruments and utensils tested were sterile at the completion of the process."

Oral Presentation - Automated Thermal Disinfection

Validation of the microbial safety of surgical instruments and utensils following Automated Thermal Disinfection cleaning by a properly designed Tunnel Washer with Ultrasonic Cleaner Solution

The application of universal precautions to instruments/utensils handling became an issue in the selection of replacement decontamination equipment for Central Sterile supply at our hospital. The new technology of an automated thermal disinfection Tunnel Washer with Ultrasonic Cleaner Treatment (TW)(CESCO TM, Mercersburg, Pa.) offered increased protection to our reprocessing staff due to decreased handling but raised concerns about the efficacy of thermal disinfection as opposed to traditional washer sterilization. Because of the limited scientific documentation of this new technology, a study was undertaken to establish the microbial safety of finished products and to identify any feature or function failure which could adversely affect outcome. The "Proper Sequence of Washer Treatments" of the thermal disinfection Tunnel Washer with Ultrasonic Cleaner Treatment progress from flush/rinse, sonic bath, wash, rinse, lubricant/deionized water (DI) sprays to drying at 240° F. for 4 minutes. The Washer Decontaminator Washer Disinfector was challenged with selected instruments and utensils that are considered to be very difficult to clean. Included were 30 each of stainless steel non-perforating towel clips and stainless steel and glass medicine cups. Each item was rinsed with a 10 5ml suspension of Staphylococcus aureus, Pseudomonsaeruginosa, Enterococcus fecalis and Candida albicans in nutrient media and then dried. The instruments wee processed in the Washer Decontaminator Washer Disinfector 3 separate loads during times of high volume operation. All products were tested for sterility. Ten separate cultures were taken of the final rinse solution of instrument lubricant and de-ionized water prior to the drying cycle. A separate culture was taken of the instrument lubricant fluid. All instruments and utensils tested were sterile at the completion of the process. The final rinse, however, was heavily contaminated with the saprophytic bacteria Flavobacterium sp., Pseudomonas (P.) picketti and P. rubrisubalbicans. The source of the contamination was determined to be resin gel in the DI tank and not the instrument lubricant. The contamination can be eliminated by the addition of a 0.22 u filter to the DI line. Our findings support the practice of validating all features of new technologies that may compromise the expected final outcome. The Washer Decontaminator Washer Disinfector is a valid replacement for the conventional washer-sterilizer.

NOTE:

Surgical Instrument Washers Tunnel Washers with Ultrasonic Cleaner Solution used in this research study were manufactured by CESCO, Mercersburg PA. Although these Surgical Instrument Washers (Tunnel Washers with automated Ultrasonic Cleaners) are not currently available. The studies demonstrate the propensity for Surgical Instrument Washers with Ultrasonic Cleaner Solution Treatment to deliver optimal cleaning results.

The surgical instrument cleaners used in these studies are currently available in the form of the all-in-ONE combination enzymatic enzyme detergent surgical instrument cleaners. A critical component for optimal cleaning is using the best possible "surgical instrument cleaners". Recent European studies have illustrated and concluded that combination enzymatic enzyme detergent surgical instrument cleaners are more effective than conventional surgical instrument cleaners. The research was initiated to deactivate prions deactivating prions within the objective to prevent CJD (Creutzfeldt-Jakob Disease).
