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.
Manufacturers of surgery instruments and surgical instrument containers recommend the use of neutral pH cleaning concentrates. Newly developed neutral pH all-in-one or combination detergent cleaning concentrates 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 against using these detergents and recommend using a neutral ph detergent. Interpreting brown 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. Prevent Surgical Instrument Corrosion using Surgical Instrument Cleaners and Ultrasonic Surgical Instrument Cleaners. Excessively hard water can contain high levels of salt sufficient to cause stains or spots that appear as rust. Boilers used to generate the steam for steam sterilizers, if not cleaned properly, will produce contaminated steam which can deposit minerals onto instruments during the sterilization process. Prevent Surgical Instrument Corrosion using the Neutral ph Surgical Instrument Cleaner recommendations by Surgical Instrument Device Manufacturers. Virtually all manufacturers of surgical instruments, rigid scopes, flexible scopes, and instrument containers recommend the use of neutral pH surgical instrument cleaning detergents. Cleaning surgical inastruments is 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. Cleaning is the prerequisite for sterilization. How is the passive oxide layer Manufactured and Maintained, the passive layer or stainless steel is intended to prevent or resist corrosion. The process is called Passivation. Passivation and Polishing eliminate the carbon molecules form the instrument surface. This forms a layer which acts as a corrosive resistant seal. Passivation is a chemical process that removes carbon molecules from the surface of the instrument. This chemical process can also occur through repeated exposure to oxidizing agents in chemicals, soaps, and the atmosphere. Polishing, by the manufacturer, is a process used to achieve a smooth surface on the instrument. Surgical Instruments are polished because the passivation process leaves microscopic pits where the carbon molecules were removed. Polishing also builds a layer of chromium oxide on the surface of the surgery instrument. 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. Proper cleaning and sterilization can cause the layer of chromium oxide to improve over time thus decreasing the possibility of corrosion and/or pitting. Second only to the financial asset value of the working staff, the surgery instrument and scope inventory is the single most financially valuable asset of the healthcare facility. It is important to properly clean, sterilize, handle, and store your instruments.
