Reducing risk, raising standards


Getting automated probe decontamination right is vital for patient safety and to protect equipment. Nanosonics outlines some key points to be aware of, to ensure the safe decontamination of ultrasound probes.


Decontamination and sterilisation are fundamental to safe ultrasound practice. Transvaginal and transrectal probes are classified as semi-critical devices because they come into contact with mucous membranes. As a result, they require high-level disinfection (HLD) between patients to minimise the risk of cross-infection. The most recent guidance from the Society of Radiographers (SoR)1


and NHS Welsh HTM2


reinforces that automated systems provide a more consistent and auditable approach than manual methods for HLD. Nanosonics’ Senior Medical Affairs Manager,


Ellie Wishart, outlines key considerations for automated ultrasound transducer decontamination, drawing on guidance from the Society of Radiographers’ article “Things to consider with automated decontamination


units” 1 by Gill Harrison, SoR Professional Officer


for Ultrasound, published in November 2024. Gill emphasises that SoR guidance highlights the importance of adequate training, audit and monitoring of processes to ensure that all ultrasound staff – regardless of their clinical background – can safely decontaminate ultrasound probes according to the examinations being carried out, to protect patients from harm. Current best practice guidance


recommends the use of automated systems for decontaminating transvaginal and transrectal ultrasound transducers, to provide a standardised and repeatable process. To reduce the chance of damage to transducers when using an automated decontamination system, there are some key points to be aware of and follow.

Six key points: 1. Ensure that the type of decontamination process used/proposed is compatible with individual probes. Manufacturers should be able to give you this information, but be aware that not all transducers might be compatible with the system you plan to use.


2. Check which wipes should be used with the decontamination system. Some wipes can affect the efficacy of the process and potentially damage the transducer. If in doubt, ask the manufacturer of the decontamination unit. Gently wipe the lens of the transducer with care. Do not use paper towels, as this can damage the lens.


3. Take care when handling the transducer and cable when moving, inserting and removing from the decontamination unit to prevent damage to the lens and/or cable.


4. If the transducer has been refurbished it may be more susceptible to damage when using an automated system. It is important to ask the retailer of the transducer and the provider of the decontamination unit for advice.


5. Cables are easily damaged. Treat it carefully when putting the transducer into the decontamination unit and back on the machine. Always avoid cables being bent or trailing on the floor when the transducer is returned to the holder. Gently place the transducer into the cradle the correct way to avoid strain on the cable.


6. Ensure that everyone who uses the decontamination unit is fully trained, updated and audited, so that they understand all steps of the procedure and the delicate nature of the transducers.


However, automation does not remove responsibility. Compatibility remains critical.
