How should the disinfectant be introduced into the lumen of a flexible endoscope?

• A. Poured directly into the opening
• B. Sprayed inside the lumen
• C. Pulled in with a syringe to remove air
• D. Soaked for a time before use

Answer: (C)

Introducing the disinfectant into the lumen of a flexible endoscope using a syringe to pull it in is the correct approach for several reasons. This method ensures that the disinfectant effectively penetrates the entire length of the endoscope's channel, promoting thorough contact with all internal surfaces. The use of a syringe allows for controlled application, which helps to remove air bubbles that could prevent the disinfectant from making full contact with the lumen surfaces. Additionally, removing air is crucial because air pockets can impede the disinfection process by obstructing the disinfectant's ability to reach and act upon all areas within the lumen. Proper disinfection relies on the disinfectant's contact with all surfaces, and utilizing a syringe facilitates that by creating a vacuum effect that draws the liquid in while ensuring uniform coverage. This method aligns with best practices in the reprocessing standards for flexible endoscopes, which emphasize the importance of using appropriate techniques to achieve effective disinfection. Soaking or pouring disinfectants in various ways, while potentially beneficial in other contexts, may not guarantee the same effectiveness in the intricate and narrow lumens of flexible endoscopes.
