1-2-4. High-Level Disinfection
Prior to high-level disinfection, the end user should confirm the minimum effective
concentration (MEC) of reused disinfectant as per the manufacturer’s instructions.
WARNING
• During the reprocessing process, always wear protective equipment
(e.g., gloves, gowns, face masks, etc.) to minimize the risk of cross
contamination.
• Prior to disinfection, it is imperative that any solutions previously used in
the cleaning process be thoroughly rinsed and dried. Failure to do so can
result in ineffective or incomplete disinfection.
• For high-level disinfection, use an appropriate disinfecting solution
according to the instructions of the disinfectant manufacturer
(temperature, concentration, time). Adhere to the instructions to
accomplish effective and complete disinfection. The endoscope may be
damaged if exposed to a disinfectant under conditions other than those
specied by the disinfectant manufacturer.
• Use only a legally marketed disinfectant that has been tested according
to the instructions provided by the manufacturer and found to be
compatible by PENTAX. A list of disinfectants that are compatible with
PENTAX endoscopes is contained in this manual.
• It is imperative that ALL internal channel surfaces be in contact with
the disinfecting solution for the time period recommended by the
manufacturer of the solution.
• Ideally, all final rinses should be performed with sterile water, clean
potable water, or water that meets the requirements of the health care
facility.
• Regardless of the quality of the rinse water used, it is essential to
perform a nal alcohol rinse followed by forced air in order to completely
dry the endoscope channels and prevent bacterial colonization and/or
infections associated with waterborne microorganisms.
• The basin that is used to perform disinfectant immersion must be
thoroughly cleaned prior to lling it with disinfectant solution.
