Surgical Instrument Cleaning prior to Surgical Instrument Sterilization. Thorough cleaning is critical for Preventing Corrosion with the passive layer of Surgical Instruments. When Surgical Instruments Cleaning prior to Surgical Instrument Sterilization, your first-line-of-defense is the passive oxide layer of Surgical Instruments.
Stainless steel surgery instruments are made of corrosion resistant high-grade specialty steels. One of the special characteristics of these steels is that the manufacturer forms a passive oxide layer on the surface, which protects them against corrosion. This makes surgery instruments as corrosion resistant as possible. It is imperative that you maintain the passive oxide layer to prevent corrosion and maintain your surgery instruments in optimal condition. If this is not done the stainless steel will be more susceptible to corrosion, pitting and stains.This will reduce the life of the surgery instruments and/or render it useless. Initially, all stainless steel surgical instruments have the same corrosion resistance. The ONEcleaner Enzyme Surgical Instrument Cleaners clean Faster. Lubricating while cleaning surgical instruments speeds the cleaning process and renders the highest quality cleaning outcomes. The ONEcleaner four enzyme surgical instrument cleaners and endoscope cleaners deliver lower cleaning costs. ONE gallon can deliver 512 gallons of enzyme surgical instrument cleaners and endoscope cleaners. When strength and hardness requirements are important factors for instrument function, corrosion resistance is generally lower. Increasing the corrosion resistance would soften the stainless steel. Manufacturers of surgery instruments and surgical instrument containers recommend the use of neutral pH cleaning concentrates. Newly developed neutral pH surgical instrument cleaners have been shown to be effective in optimizing the efficacy of the passive oxide layer. This will provide a longer life for stainless steel surgery instruments. Cleaning concentrates with a high or low pH have been shown to erode the passive layer. The most common of these cleaning concentrates utilize an alkaline detergent with an acid neutralizer. Virtually all manufacturers of surgical instruments and surgical instrument containers recommend using a neutral ph detergent. Surgical Instrument Cleaners and Ultrasonic Surgical Instrument Cleaner Solution Neutral pH Cleaning Concentrates recommended by Device Manufacturers. Virtually all manufacturers of surgical instruments, rigid scopes, flexible scopes, and instrument containers recommend the use of neutral pH Cleaning Concentrates. Rinsing Instruments Tap Water when using Surgical Instrument Cleaners and Endoscope Enzyme Cleaners. Tap water can contain many minerals, which may discolor and stain surgical instruments. It is recommended that de-ionized 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. Cleaning is the prerequisite for sterilization. Studies regarding the passive oxide layer of Surgical Instruments 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 cleaning, handling, and sterilization will build up the layer of chromium oxide and protect the Surgical Instrument from corrosion and /or pitting. In some circumstances older instruments have higher resistance to corrosion than new ones. The newer instruments have not had the time to build up the chromium oxide layer. Improper cleaning and sterilization can cause the layer of chromium oxide to disappear or become damaged thus increasing the possibility of corrosion and/or pitting.
