What is Cleaning?

Cleaning a transesophageal echocardiogram (TEE) ultrasound probe is vital to achieving high-level disinfection. The Centers for Medicare & Medicaid Services' (CMS) Infection Control Surveyor Worksheet states: "Pre-cleaning must always be performed prior to sterilization and high-level disinfection." Cleaning TEE probes, sometimes called pre-cleaning, is critical to a successful disinfection and to the integrity of the probe itself and must never be skipped. But when dealing with various semi-critical devices, there is so much jargon used, it can be hard to know what is even meant by "cleaning".

What is cleaning?

According to The Centers for Disease Control and Prevention (CDC), "Cleaning is the removal of foreign material (e.g., soil, and organic material) from objects and is normally accomplished using water with detergents or enzymatic products. Thorough cleaning is required before high-level disinfection and sterilization because inorganic and organic materials that remain on the surfaces of instruments interfere with the effectiveness of these processes."

How to clean a TEE probe

Immediately after removing a TEE ultrasound probe from a patient's esophagus, probes must first be bedside cleaned with an enzymatic product, like the TEEZyme® TEE Probe Enzymatic Sponge. This step removes some of the bioburden left on the shaft of the TEE probe and prevents what is left from hardening into biofilm. After this, the probe can be securely transported to the location where cleaning and disinfection can take place. The TPorter® TEE Ultrasound Probe Transportation Case keeps the delicate TEE probe's shaft and distal tip safe while protecting others from the biohazards a soiled probe presents.

The probe should then be rinsed to remove the bedside cleaning solution with a large volume of tempered water. The general recommendation is one minute of contact time per eight liters of water. Then a basin or sink should be filled with tempered water along with an enzymatic solution, like TEEZyme® MC Enzymatic Cleaner, for an enzymatic bath.

Next, the TEE probe's shaft should be submerged in this bath for the manufacturer's directed time found in the instructions for use. The handle and cable must not be submerged to avoid damage to the ultrasound probe. After the enzymatic bath is complete, the basin or sink should be emptied and a large quantity of fresh, tempered water should be used to rinse the TEE probe.

A drying step using a contaminant-free product, like the QwikDry® Ultrasound Probe Drying Cloth, is recommended before high-level disinfection. This eliminates excess moisture that may interfere with microbicidal processes.

What do inspectors look for?

It's pretty simple. Regarding cleaning, inspectors will be asking two questions:

1. Are you following the manufacturer's instructions for cleaning or evidence-based guidelines?

2. Are you visually inspecting probes prior to high-level disinfection for residual soil and re-cleaning as needed?

Is cleaning still required if using an automated reprocessor?

When using a standard automated high-level disinfector, yes. Units like the TD 100® Automated TEE Probe Disinfector and the TD 200® Automated TEE Probe Disinfector only high-level disinfect probes. As with manual disinfection methods, you must always start the disinfection process with a clean probe.

If, however, your facility is using the TEEClean® Automated TEE Probe Cleaner Disinfector, the cleaning step is actually automated by your TEEClean. After bedside cleaning the TEE probe, you can simply insert the soiled probe into TEEClean and it will clean and then high-level disinfect your probe automatically, saving you time and avoiding the risks associated with manual reprocessing.

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.
