What is the correct means of sterilizing a non-flexible fiber optic endoscope?

The correct means of sterilizing a non-flexible fiber optic endoscope is through the use of peracetic acid. Peracetic acid is a powerful chemical agent known for its efficacy in achieving high-level disinfection and sterilization. It works by disrupting cellular processes and is capable of killing a wide range of microorganisms, including bacteria, viruses, and fungi.

Fiber optic endoscopes, especially non-flexible ones, can be sensitive to certain sterilization processes. While steam sterilization is a common method for many surgical instruments, the high heat and moisture can damage the delicate components of fiber optic devices. Alcohol, while disinfectant, does not provide the same level of sterilization as peracetic acid and is typically not effective against spores. Phenol is also not utilized for sterilization in surgical settings due to harshness and potential toxicity.

Therefore, peracetic acid is the preferred choice for ensuring that non-flexible fiber optic endoscopes are thoroughly sterilized while preserving their integrity.
