Which type of equipment is used in the disinfection of endoscopes?

• A. Autoclave
• B. Automatic Endoscope Reprocessor (AER)
• C. Ultrasound machine
• D. Surgical laser

Answer: (B)

The Automatic Endoscope Reprocessor (AER) is specifically designed for the safe and effective disinfection of endoscopes. This equipment facilitates the cleaning, disinfection, and rinsing process in a controlled environment, ensuring that stringent infection control protocols are followed. Endoscopes, being delicate and complex instruments that penetrate body cavities, require specialized cleaning procedures to prevent contamination and ensure patient safety.

Unlike an autoclave, which uses high-pressure steam for sterilization, the AER employs chemical disinfectants to achieve a high level of disinfection suitable for heat-sensitive devices. The ultrasound machine and surgical laser, while important in their respective roles in surgical environments, do not serve the purpose of disinfection for endoscopic instruments. The AER’s design particularly addresses the unique challenges posed by endoscopes, such as their intricate lumens and varied materials, making it the optimal choice for their reprocessing.
