The proper sequence of surgical instrument washer disinfector cycles will deliver consistently clean medical devices that are safe to handle and have received the prerequisite for sterilization.
Example of proper surgical instrument cycle washing temperatures:
- cold water pre wash cycle: ambient to 95 F, 35 C
- wash enzymatic and detergent cycle: 131 to 137 F, 55 to 58 C
- elevated thermal rinse cycles with lubrication: 194 to 209 F, 90 to 98 C
- hot air dry cycle with disinfecting temperatures: 158 to 230 F, 70 to 110 C
In the United States manufacturers of Surgical Instrument Washers are not approved by the FDA to market their products as "washer disinfectors". However, many of the medical surgical instrument washers are manufactured to produce the times and temperatures that can effectively deliver disinfected surgical instruments. If it is your preference to have cleaning reprocessing results of a washer disinfector, refer to the surgical instrument washer specifications for assurance that the times and temperatures available are those you consider to be appropriate for disinfecting surgical instruments. Automated Surgical Instrument Washer Decontaminator Disinfectors can safely contain within their chambers the cleaning-decontamination-reprocessing functions, removal of debris, and contaminated aerosols. The batch treatment of reprocessing surgical instruments using automated Surgical Instrument Washer Decontaminators Disinfectors saves time, increases material through-put, improves surgical instrument turnaround times, provides for FTE reduction, and lowers cost for surgical instrument cleaners. It has been demonstrated that a properly designed Surgical Instrument Washer Decontaminator Disinfector, that is used to manufacturer’s specifications, will consistently and repeatedly remove all microorganisms from surgical instruments. Surgical instrument washers and washer disinfectors should be used in accordance with the manufacturer’s direction for use, to secure the most consistent and efficacious results. educe the risk to Reprocessing personnel whenever possible. The use of a properly designed surgical instrument washer decontaminator disinfector reduces the: overhead cost of reprocessing, risks to the reprocessing staff and provides consistence removal of all microorganisms from soiled surgical instruments. Once a surgical instrument is clean, it is then safe for further reprocessing and handling. Proper cleaning surgical instruments prior to sterilization is the prerequisite for disinfecting and/or sterilizing surgical instruments.
