4 Enzyme Detergent Surgical Instrument Cleaner
Summary : Properly Designed Tunnel Washers, Washer Decontaminators, Washer Disinfectors, are designed to clean all surfaces thoroughly, thereby providing the critical prerequisite for the safe handling, disinfecting, and the sterilizing of surgical instruments.
Critical cleaners, usually referred to as Washer Decontaminators Washer Disinfectors, perform pre-wash, ultrasonic (optional), detergent washing, purified water elevated temperature rinsing, lubrication and high temperature drying in such a manner as to provide thoroughly clean, stain free and lubricated medical devices. Surgical Instruments cannot be sterilized (be sterile) unless all exposed surfaces are properly cleaned, prior to sterilization, to remove soil (debris, bioburden) and properly rinsed to prevent staining.1,2,3 Not all Washer Decontaminators Washer Disinfectors provide adequate pre-rinsing, pre-cleaning, purified water rinsing, and thereby render higher rejection rates of processed surgical instruments. 4,5.
Proper Washer Decontaminator Washer Disinfector Design Secures Performance
The proper sequence of treatment and the correct choice of time, temperature and the components used are necessary to render surgical instruments that are critically clean, safe to handle, and have the prerequisite for sterilization. 6,7,8.
Washer Decontaminators Washer Disinfectors employ a cold water pre-wash to remove gross debris. This removes proteins and lipids, preventing them from being baked onto devices during the high temperature treatments to follow. 9, 10. Then, the ultrasonic process creates millions of micro implosions to loosen and free debris from lock boxes, hinge pins, serrations and other difficult-to-access surface areas.
The Washer Decontaminators Washer Disinfectors detergent wash then applies high flow low pressure water with a cleaning concentrate (at ~ 135 degrees F) in such a manner as to evenly reach all areas of the load and strip bioburden from the surgical instruments. The elevated temperature (at ~ 194 to 209 degrees F) purified water final rinse secures the biocidal process, removes mineral deposits from prior cycles and lubricates the instruments. The high temperature (at ~ 158 to 230 degrees F) dry cycle presents heated, forced air which dries each device. The critical cleaned medical devices are now clean, safe to handle, have the prerequisite for sterilization, and are properly prepared for further reprocessing.
Washer Decontaminator Washer Disinfector - Complete Removal of Pathogens
The Washington University School of Medicine at Washington University Medical Center examined the performance of a properly designed Washer Decontaminator Washer Disinfector (CESCO washer Decontaminator Model 520) and found that it removed all organisms from the surgical instruments tested. 11
The Washer Decontaminator Washer Disinfector was tested for its ability to complete remove pathological organism from surgical instruments.
Pure cultures of the following organisms were grown on appropriate agar plates:
1. Staphylococcus aureus;
2. Pseudomonas aeration's;
3. Escherichia coli;
4. Bacillus species
Kelly clamps, tweezers and scissors wee placed on these plates of organism, taking care to ensure that all serrated edges were packed with all the organisms. Each contaminated instrument was then dipped into the tube of Thiogycolate medium before being placed in all the washer baskets. The instruments were then processed through the complete Washer Decontaminator Washer Disinfector cycle. At the end of the drying cycle, the instruments were allowed to cool and then dipped into another tube of Thioglycolate medium.
Results
All tubes of the Thioglycoate medium tested before the wash grew the appropriate organism within six to 18 ours after testing. All tubes tested at the end of the wash showed no growth after 14 days of incubation. This Washer Decontaminator Washer Disinfector removed all organisms from the instruments.
Washer Decontaminator Washer Disinfector Efficacy of Disinfection 100%
Another evaluation of Washer Decontaminators Washer Disinfectors confirmed that the efficacy of disinfection was 100%. In this study, L.P. Jette and N.G. Lambert used two test methods.12 One method (N) was to test the effect of heat only within the disinfection process and the other test method (G) was to test the efficacy of both heat and washing. Each method gave reproducible results and confirmed the efficacy of the Washer Decontaminator Washer Disinfector.
Washer Decontaminator Washer Disinfector Critical Cleaners Will Work for You
Washer Decontaminator Washer Disinfector Critical cleaners demonstrated the ability to completely remove pathological organisms with effective repeatability. There operation is automatic, reliable, labor saving and easy to use. Central Processing departments rarely find the need to manually treat devices and report an exceptionally low rate of rejected devices.
Conclusion
The Washer Decontaminator Washer Disinfector sequence, cold water pre-wash, ultrasonic cleaning, detergent washing action, final rinse and drying treatment of a properly designed Washer Decontaminator Washer Disinfector Critical Cleaner will provide critical cleaning, the prerequisite for safe handling, optimal disinfecting, and sterilizing of medical devices.

NOTE: The goal of cleaning (decontaminating reprocessing) surgical instruments is to deliver Clean Surgical Instruments that are safe for the Reprocessing Staff and have received the prerequisite for disinfecting and/or sterilizing surgical instruments. It is a recognized risk of exposure to unidentified microorganisms that reprocessing personal endure during the decontamination, reprocessing, and cleaning of surgical instruments. Our goal is to minimize the amount and degree of reprocessing personal exposure to this risk and provide reprocessed surgical instruments that are clean: safe to handle, safe for patient care, and are cleaned (decontaminated reprocessed) at the lowest cost. The optimal decontamination cleaning-reprocessing of surgical instruments will secure the prerequisite for disinfecting surgical instruments and/or sterilizing surgical instruments, deliver surgical instruments that are safe to handle, and reduce reprocessing costs.
Surgical Instrument Washers with Ultrasonic Surgical Instrument Cleaner used in this research study were manufactured by CESCO, Mercersburg PA. The Surgical Instrument Washers with an integrated Ultrasonic Surgical Instrument Cleaner are not currently available from CESCO. European Manufacturers have developed Surgical Instrument Washers with fully automated Ultrasonic Cleaning manufactured within the ISO/DIS 15883-1 Standard. Studies demonstrate the propensity for Surgical Instrument Washers with Ultrasonic Cleaning to deliver optimal cleaning results.
The surgical instrument cleaners used in these studies are currently available in the form of the all-in-ONE 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).
The "Proper Sequence of Washer Treatments" includes a series of mechanical and chemical treatments. The mechanical treatments include: cold water pre-wash, ultrasonic cleaning, detergent wash, purified water rinses, and hot air drying. The chemical treatments include combination of enzymatic enzyme cleaners, detergents, surface conditioners and lubricants.

The Goal Purpose of a Surgical Instrument Washer
The purpose of an Instrument Washer is to deliver surgical instruments that are "clean and safe to handle" for reprocessing and are clean so that they can be sterilized. Surgical instruments that are not clean cannot be sterilized. Surgical Instrument Washer can properly prepare surgical instruments for sterilization by Terminal Sterilizers. Clean is the "Prerequisite for Sterilization".
