What should NOT be left in the channels of the endoscope after the cleaning process?

• A. Disinfectant residue
• B. Water
• C. Cleaning solution
• D. Air

Answer: (A)

Disinfectant residue should not be left in the channels of the endoscope after the cleaning process because it can be harmful to both the scope and the patient. Disinfectants are typically formulated for specific contact times and conditions; if residue remains, it can lead to potential chemical reactions that may damage the delicate internal components of the endoscope or irritate patient tissues during subsequent procedures. Proper rinsing is essential to remove any traces of cleaning and disinfecting agents to ensure safety and effectiveness. In contrast, ensuring that channels are clear of water after rinsing is important as it can lead to mold or bacterial growth. Similarly, while cleaning solutions are essential during the cleaning process, they must be thoroughly rinsed to avoid residue. Air is commonly used to facilitate drying after cleaning, making it safe and beneficial to leave in the channels as long as no moisture remains, ensuring that the endoscope is sterile and ready for reuse.
