Which chemical is used in the reprocessing of flexible endoscopes?

Peracetic acid is commonly used in the reprocessing of flexible endoscopes due to its effective antimicrobial properties. It acts as a potent disinfectant and is capable of killing a broad spectrum of microorganisms, including bacteria, viruses, and fungi. The effectiveness of peracetic acid is enhanced by its ability to work in the presence of organic matter and organic debris that might be present after an endoscopic procedure. Additionally, it breaks down into non-toxic byproducts, making it safer for both the environment and health care workers performing the reprocessing.

In contrast, hydrochloric acid is primarily used for cleaning and removing mineral deposits but is not a reliable disinfectant for flexible endoscopes. Phenolic compounds may be used for environmental surface disinfection but are less common in high-level disinfection of flexible endoscopes. Chlorines are also used as disinfectants but can be corrosive and harmful to the delicate materials and mechanisms of flexible endoscopes, limiting their use in endoscope reprocessing. Therefore, peracetic acid is the preferred choice for ensuring the high-level disinfection of flexible endoscopes.
