Proper surgical instruments cleaning will strengthen and maintain the passive layer of surgical stainless steel to prevent surgical instrument corrosion. Preventing the pitting and corrosion of surgical instruments is possible with the proper surgical instrument cleaning protocol that dictates proven methods for the proper cleaning and conditioning of surgical instruments.
Yellow-brown to dark-brown stains or spots on surgical stainless steel instruments are frequently mistaken for rust. These residue deposits stains or spots arranged in groups or along edges or in crevices are usually the instrument being exposed to result of high chloride content. They will lead to pitting of the surgical instrument surface if not removed. Excessively hard water can contain high levels of salt sufficient to cause stains or spots that appear as rust.
It is recommended that deionized water be used for the final rinsing to prevent spotting. all-in-one or combination cleaning concentrates can be effective in treating unacceptably hard source water and removing hard water encrustation from surgical instruments and equipment. If untreated tap water is used for final rinsing, then the instruments must be dried immediately to avoid staining.
Clean instruments, or apply treatment to prevent the drying and encrustation of debris, as quickly as possible after use. Do not allow blood and debris to dry on the instruments. If cleaning must be delayed, place groups of instruments in a covered container with appropriate enzyme-detergent or apply an enzyme-detergent foam spray to delay drying. The use of pre-soaking enzyme-detergent foam sprays have been shown to reduce the time expended for manual cleaning and render higher quality outcomes. After surgery, open all box locks and disassemble instruments with removable parts. Cleaning the Prerequisite for Sterilization The reprocessing decontamination process, whether done manually or automatically in a washer-decontaminator- disinfector, can only be effective if cleaning is adequate.
Ultrasonic Cleaners do not provide the complete proper sequence of treatments such as using purified final rinses, purged between treatments and using temperatures elevated to disinfection levels. Preventing corrosion, proper surgical instruments cleaning will build the passive layer of to prevent surgical instrument corrosion. Prevent the pitting of surgical instruments is possible with the proper surgical instrument cleaning protocol. Ultrasonic Cleaning can effectively remove: long term encrustation and surgical cements or glues that have dried onto instrumentation. Lubrication of Surgical Instruments To maintain moving parts and protect instruments from staining and rusting during sterilization and storage, they should be lubricated with a water-soluble, preserved lubricant after each cleaning. Most automated washer decontaminators provide the option for lubrication at the end of the final rinse treatment. Since effective ultrasonic cleaning removes all lubricant, re-lubrication is important. The all-in-one surgical instrument cleaning detergent cleaning concentrates will provide lubrication. The lubricant should contain a chemical preservative to prevent bacterial growth in the lubricant bath. The bath solution should be made with demineralized water. A lubricant containing a rust inhibitor helps prevent electrolytic corrosion of points and edges. Immediately after cleaning, instruments should be immersed or rinsed for 30 seconds and allowed to drain off, not wiped off. A lubricant film will remain through the sterilization to protect surgery instruments during storage. Prevent Staining and Spotting when cleaning surgical Instruments. Staining and spotting may result if residual chemicals are not completely rinsed from surgery instruments that are subjected to steam sterilization. Following the manufacturer’s recommendations for the proper sequence of treatments (cold water pre-wash, enzyme-detergent wash, purified water rinse/lubrication, and drying) is critical to prevent stains and spots. A Cleaning Concentrates that will avoid spotting are free-rinsing or rinse clean. Studies regarding the passive oxide layer of Surgical Instruments (Guidelines on metals and alloys in contact with food; Council of Europe; published 11.10.2000. Systemic nickel: the contribution made by stainless steel cooking utensils; Contact Dermatitis, Volume 32:2, 1994) of the stainless steel passive layer to prevent corrosion have revealed a reduction in corrosion prevention with the use of cleaning concentrates that are not neutral pH. The use of cleaning concentrates that deliver an acid rinse will release nickel from the stainless steel and decrease the efficacy of the passive layer. This is most critical on initial reprocessing events of stainless steel surgical instruments. Measurable levels of nickel have been detected. It was also shown that, as the number of subsequent uses increased, the level of nickel release diminished and reached a steady state (measured in the order of μg/l). These observations reflect the changes that occur in the passive oxide layer on first immersion of stainless steels in aqueous media. Proper surgical instruments cleaning will build the passive layer of to prevent surgical instrument corrosion. Preventing the pitting and corrosion of surgical instruments is possible with the proper surgical instrument cleaning protocol that dictates proven methods for the proper cleaning and conditioning of surgical instruments. Neutral pH 7 surgical instrument cleaning solutions are recommended by all surgical instrument and container manufacturers. The all-in-one enzyme surgical instrument cleaners delvers water softeners that treat the source water to counter the corrosive effects of source hard water that contains high mineral levels, and a free rinsing ingredient breaks the surface tension of the final rinse for spotless and residue free surgical instruments. The all-in-ONEcleaner enzyme surgical instrument cleaner delivers all of the ingredients necessary for effectively cleaning and maintaining surgical instrument stainless steel.
