Which ingredient is commonly recommended in cleansers for intracavitary probes?

• A. Acetone
• B. Iodine
• C. Glutaraldehyde
• D. Bleach

Answer: (C)

Intracavitary probes need high‑level disinfection between patients because they contact mucous membranes. A cleanser containing glutaraldehyde is commonly recommended because it acts as a high‑level disinfectant, killing a broad range of pathogens—including bacteria, viruses, fungi, and mycobacteria—within a practical immersion time. Probes are typically cleaned first and then immersed in a 2% glutaraldehyde solution for the recommended contact time, followed by thorough rinsing to remove residues before reuse. This approach provides strong disinfection while being compatible with the probe’s materials, unlike harsher cleaners. Acetone is just a solvent and not a disinfectant; iodine is mainly for skin antisepsis and isn’t sufficient for high‑level disinfection of probes; bleach can be effective but may corrode equipment and leave residues.
