What disinfectant is used for sterilizing bronchoscopes?

Chlorine
Alcohol
Alkaline glutaraldehyde (Cidex)
Benzalkonium chloride

The correct answer is: Alkaline glutaraldehyde (Cidex)

The use of alkaline glutaraldehyde, commonly referred to as Cidex, for sterilizing bronchoscopes is based on its effectiveness as a high-level disinfectant. Glutaraldehyde is a chemical agent that destroys a wide range of microorganisms, including bacteria, viruses, and fungi, making it suitable for the disinfection of medical instruments that come into contact with mucous membranes or sterile tissues, such as bronchoscopes. Bronchoscopes require high-level disinfection to eliminate the risk of infection that could arise from their reuse on different patients. Cidex achieves this by penetrating and attacking microbial cell structures, ensuring that any pathogens are effectively neutralized. Its use also follows strict protocols established by health agencies to maintain patient safety and minimize infection risk. Furthermore, Cidex can remain effective for extended periods when used properly, allowing for the safe, repeated use of bronchoscopes without compromising sterility. This makes it the preferred choice among medical professionals for ensuring that bronchoscopes are adequately disinfected between procedures.
