Reprocessing surgical instruments, using the 'proper sequence of treatments", can deliver superior cleaning outcomes. The evaluation of the surgical instrument washer using the proper sequence of washer treatments, with an effective surgical instrument detergent, confirmed that the efficacy of disinfection was 100%. and all of the instruments and utensils tested were sterile at the completion of the washing process.
ONEcleaner Surgical Instrument Detergents for: soaking dried on debris, removing stains, manually cleaning, ultrasonic cleaning, and surgical instrument washer disinfectors deliver superior cleaning outcomes.
The proper sequence of surgical instrument cleaning treatments has been proven to remove all pathogens. After being washed in a properly designed surgical instrument washer, that used an enzyme detergent surgical instrument cleaning lubricant solution: all instruments and utensils tested were sterile at the completion of the process.
Eighteenth Annual Conference and International Meeting
Oral Presentation, Ann Drake,
Validation of the microbial safety of surgical instruments following cleaning by a properly designed surgical instrument washer
A. Drake, RN and L. Ayers, MD.
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 surgical instrument washer, (CESCO Mercersburg, PA) offered increased protection to our reprocessing staff. The study was conducted due to concerns pursuant to the efficacy of thermal disinfection, as opposed to using a 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 surgical instrument washer proper sequence of treatments used was: cold water pre-wash, enzyme ultrasonic sonic bath, detergent wash, purified water rinses, instrument lubricant rinse, and hot air drying at 240 F for 4 minutes. The surgical instrument washer decontaminator 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, Pseudomonsa eruginosa, Enterococcus fecalis and Candida albicans in nutrient media and then dried. The instruments were processed in the Surgical instrument Washer 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 culture was taken of the instrument lubricant fluid. All instruments and utensils tested were sterile at the completion of the process. Our findings support the practice of validating all features of new technologies that may compromise the expected final outcome. The Surgical instrument Washer is a valid replacement for the conventional washer-sterilizer.

surgical instrument washers
and the sequence of washer treatments
The purpose of a surgical instrument washer is to deliver surgical instruments that are clean and safe to handle for reprocessing, and are critically clean, so that they can be sterilized. Surgical instruments that are not clean cannot be sterilized. Surgical instrument washers prepare surgical instruments for terminal sterilization. Proper cleaning is the prerequisite for sterilization.
After being cleaned in a properly designed surgical instrument washer, that included using a four enzyme surgical instrument detergent cleaning solution: the evaluation of the surgical instrument washer using the proper sequence of washer treatments confirmed that the efficacy of disinfection was 100%.
All instruments and utensils tested were sterile at the completion of the washing process.
The proper sequence of surgical instrument washer treatments includes a series of mechanical and chemical treatments.
The surgical instrument washer mechanical treatments include: cold water pre-wash, ultrasonic cleaning cycle, surgical instrument detergent wash, purified water rinses, and hot air drying.
The chemical treatments include: four enzyme cleaners, (Lipase, Amylase, Carbohydrase, and Protease), surface cleaning deterrents, surface conditioners, stain remover, and water soluble surgical instrument lubricant.
