What level of disinfection should be used for cleaning ultrasound probes?

The appropriate level of disinfection for cleaning ultrasound probes is intermediate-level disinfection. This level of disinfection is critical to ensure that probes, which can come into contact with non-intact skin or mucous membranes, are effectively decontaminated without causing damage to the equipment.

Intermediate-level disinfection typically involves the use of chemicals that can kill a wide variety of pathogens, including bacteria and viruses, making it suitable for devices like ultrasound probes that may contact patient skin. This method strikes a balance between safety for the equipment and effective microbial control.

Low-level disinfection is insufficient for ultrasound probes because it does not eliminate all pathogenic organisms, particularly more resilient bacteria and viruses, that could pose a risk to patients. High-level disinfection, while effective, is generally reserved for instruments that are inserted into sterile body areas, higher risk procedures, or reusable surgical instruments. Non-disinfection, as the term suggests, would not provide any reduction of microbial presence and is therefore not acceptable for any medical device that contacts patients.

Ultimately, the choice of intermediate-level disinfection for ultrasound probes ensures that they are safe for use, protecting both patients and the integrity of the equipment.
