1.4 Precautions

1.4

Ch.1

Precautions WARNING • An insufficiently reprocessed endoscope and/or accessory may pose an infection control risk to the patients and/or operators who touch them. • The endoscope reprocessor, video system center, light source, front panels of equipment, and/or mouthpiece may cause an infection control risk. Perform proper cleaning and/or disinfection as described in their respective instruction manuals. A tap, basin, and/or nozzle of pharyngeal anesthetic spray that medical personnel come in contact with may cause an infection control risk as well. Perform proper replacement, cleaning, and/or disinfection. • All disinfection methods (whether performed manually or by an AER/WD) and all sterilization methods (whether performed by ethylene oxide gas or low temperature steam) require thorough prior cleaning of the instruments being reprocessed. If the instruments are not adequately cleaned prior to disinfection/sterilization, these processes will be ineffective. Immediately after each patient procedure and before disinfection/sterilization, thoroughly clean the endoscope and the accessories used with the endoscope. • Residual disinfectant solution and detergent solution may cause adverse reactions in patients. Therefore, rinse all external surfaces of the endoscope and accessories thoroughly with water to remove residual disinfectant solution following disinfection and detergent solution following cleaning. • The results of sterilization depend on various factors. These factors include how the equipment was packaged and the placing and loading of the package in the sterilization device. Verify the sterilization process using biological and/or chemical indicators. Follow the guidelines for sterilization issued by national authorities, professional organizations, and infection control professionals, including the frequency of the above verification, as well as the instruction manual for the sterilization device. • Establish an internal system of identifying contaminated versus reprocessed endoscopes and accessories to prevent both mix-ups and cross-contamination. Some national or professional guidelines recommend separating dirty (contaminated) area, clean area, and storage area. Touching a reprocessed endoscope and/or accessories with contaminated gloves or placing them on a contaminated hanger or surface, including letting them touch the floor, will recontaminate them.

1.4 Precautions

Ch.1

WARNING • Prior to each patient procedure, confirm that the endoscope and accessories have been properly reprocessed and stored. If there are any doubts or questions, reprocess them again before the patient procedure, following the instructions given in this manual. • Perform a leakage test on the endoscope after each precleaning procedure. Do not use the endoscope if a leak is detected. Use of an endoscope with a leak may damage to the bending mechanism, or other malfunctions. Use of a leaking endoscope may also pose an infection control risk. • The accessories listed on the front cover of this manual cannot be refurbished or repaired and are intended to be replaced once they show any signs of wear and tear. Should any irregularity be observed, use a replacement accessory instead. Using defective accessories may cause equipment malfunction, reduce the efficacy of reprocessing, present a risk to patients and/or operators, or damage the endoscope and/or accessories. • Patient debris and used reprocessing chemicals pose infection control risks. To guard against contact with dangerous chemicals and potentially infectious material, wear appropriate personal protective equipment during reprocessing. Such protective equipment should include appropriate eyewear, face mask, cap, moisture-resistant clothing, shoe covers, and chemical-resistant gloves that fit properly and are long enough to prevent skin exposure. • The reprocessing room must be adequately ventilated to minimize the risks from chemical vapors. • Always remove contaminated personal protective equipment before leaving the reprocessing area to prevent contamination from spreading. • Only Olympus-recommended or Olympus-endorsed AERs have been validated by Olympus. When using an AER that is not recommended by Olympus, the manufacturer of the AER is responsible for validating compatibility of the AER with each Olympus endoscope, accessories, and medical instruments. • Only use the AER/WD that meets the requirements of the relevant parts of EN ISO 15883 series in the member states of the EU. • Before using an AER/WD, confirm that it is capable of reprocessing the endoscope, accessories, and medical instruments. Be sure to attach all required connectors. Otherwise, insufficient reprocessing may pose an infection control risk. If you are uncertain as to the ability of your AER/WD to reprocess the endoscope, accessories, and medical instruments, contact the manufacturer of the AER/WD for specific instructions and information on compatibility and required connectors.
