FAQ: Do You Dry Ultrasound Probes Properly?

FAQ: Do You Dry Ultrasound Probes Properly?

After bedside cleaning, cleaning, and then high-level disinfecting a TEE ultrasound probe, it’s time to give it a quick wipe with a paper towel and store it. If this sounds familiar, you’re not drying your probes properly. Let’s review some of the most common approaches taken to drying ultrasound probes and discover what the most effective method is.

Not Drying

Some facilities take a high-level disinfected probe and immediately store it in a sheath or hang it to dry. By leaving a wet ultrasound probe to dry on its own, you might completely invalidate all the care taken to disinfect the probe in the first place. This must not be done; a wet probe allows airborne contaminants to stick to it and fosters the growth of spores and bacteria. It may even lead to the development of biofilm. This puts patients at risk of contracting a healthcare associated infection (HAI). Worse, yet, is storing a wet or damp probe in a sheath; the sheath becomes an incubator and creates the perfect environment for the growth of bacteria.

Paper Towels

Another common practice is to dry probes before storage, but with materials that are unsuitable for the purpose. Paper towels are often used, but many do not realize just how abrasive a paper towel is on the delicate shaft and lens of a probe. Paper towels are made of, you guessed it, paper. And paper is made of wood. When a paper towel is wiped along the surface of a probe, those tiny shreds of wood are scratching and damaging the shaft’s surface and the lens of the probe, degrading image quality over time.

Additionally, paper towels are not individually wrapped and are often handled by various individuals before arriving at dispensers for use. As a result, they may introduce bacteria to the probe’s shaft, making it a health hazard. Not to mention the fact that paper towels leave lint behind, making them problematic as the next patient does not need paper towel fragments introduced into their body.

Guaze

Some facilities employ the use of gauze. Being typically made of soft cotton fibers, damaging the probe surface is not a concern here. It also tends to come individually wrapped and is contaminant-free, lowering the chances of introducing a new contaminant. The gauze however will not slide down the shaft smoothly which could lead to frustration and improper drying.

The gauze also presents the issue of lint. As anyone who has ever had gauze put over a wound knows, cotton fibers easily get stuck in a wound, causing pain and discomfort. The same principle applies to the probe shaft: cotton fibers are left behind for the next patient to ingest; not a desired option.

Sponge

A reusable sponge is sometimes employed to wipe away excess moisture from an ultrasound probe before storage. Sponges have the advantage of being non-abrasive while not leaving behind lint or fragments on the probe. Sponges, however, have one significant disadvantage: they harbor bacteria and are hard if not impossible to decontaminate. As a result, wiping a high-level disinfected probe with a sponge is very likely to reintroduce bacteria to the shaft, making all efforts at disinfection pointless.

QwikDry®

TEE probes need to be thoroughly dried before storage with a material that is non-abrasive, low lint, and free from contaminants. QwikDry® Ultrasound Probe Drying Cloths are trusted by increasingly more facilities to dry ultrasound probes and with good reason: QwikDry eliminates the issues associated with all the other drying methods. QwikDry cloths are individually packaged and irradiated, ensuring they will not undo the work of high-level disinfection. They are also engineered to have an ultra-smooth surface that will not damage the probe shaft. Lastly, they are low lint, removing fears that material from the cloth will find its way into an unsuspecting patient.


About CS Medical

CS Medical LLC has pioneered the automated disinfection process for Transesophageal ultrasound probes with the development and release of the TD 100® Automated TEE Probe Disinfector. In 2005, the TD 100 was the first FDA cleared automated disinfection process with printed verification for Transesophageal ultrasound probes. During the disinfection process, the TEE probe receives high-level disinfection in (5) five minutes from TD-5® or TD-8® followed by (5) five complete rinse cycles before disinfection confirmation is acknowledged and a report is printed. The verification report indicates probe contact time with the high-level disinfectant as well as the average temperature of the single-use disinfectant during each cycle.

For more than 15 years and over 4 million high-level disinfections, the TD 100 Automated TEE Probe Disinfector has eliminated manual reprocessing of delicate and expensive TEE ultrasound probes while also providing a repeatable and FDA cleared disinfection process. The TEEClean® Automated TEE Probe Cleaner Disinfector will continue the TD 100's work by automating the required cleaning process for the TEE probe before high-level disinfection. TEEClean, with electronic record data logging, printed verification reporting, FDA cleared cleaning, and high-level disinfection will be the standard of care for TEE ultrasound probes.

CS Medical's TEE Complete Care® products provide quality device care and storage by minimizing healthcare operational costs, improving service readiness and increasing regulatory compliance.
