Ensuring Patient Safety During Process Downtime: A Comprehensive Guide to Reprocessing TEE/TOE Ultrasound Probes

In the healthcare environment, maintaining the highest standards of hygiene and patient safety is crucial. This is especially true for the reprocessing of transesophageal echocardiography (TEE) or transesophageal echocardiogram (TOE) ultrasound probes. These delicate instruments require meticulous care and cleaning to prevent infection and ensure accurate diagnostics. But what happens when your reprocessing unit or current process goes down? Having a contingency plan is essential. Here is a comprehensive guide to reprocessing TEE/TOE probes during such times.

Step 1: Immediate Pre-Cleaning at Bedside

Apply Enzymatic Cleaner:

At the patient's bedside, immediately after removing the probe, apply an enzyme cleaner to the probe shaft using a cloth or appropriate applicator such as a presaturated enzymatic sponge. This step is critical to prevent the drying of organic and inorganic material on the probe, which can lead to biofilm formation, posing a significant risk to patient safety.

Step 2: Temporary Storage and Transport

Secure and Contain:

Place the pre-cleaned probe in a secure, leak-proof container for safe transport. Make sure the container is clearly labeled and compliant with infection control protocols to avoid any cross-contamination.

Step 3: Manual Cleaning

Prepare Enzymatic Cleaning Solution:

Prepare a basin with a tempered enzymatic cleaning solution per the manufacturer’s instructions.

Soak and Clean:

Submerge the probe shaft in the enzymatic solution for the recommended duration, typically 2-3 minutes. Ensure that the handle and cabling, which are not liquid-sealed, are not submerged.

?

Step 4: Rinse and Dry

Rinse Thoroughly:

Rinse the probe thoroughly with clean water to remove all traces of the enzymatic cleaner. Use a low-lint cloth to dry the probe shaft completely to prevent any residual moisture that could harbor bacteria.

Step 5: Electrical Leakage Testing

Perform Leakage Test:

Conduct an electrical leakage test on the dry probe shaft per the manufacturer's instructions to ensure it is safe for use. This step is critical to verify the integrity of the probe and prevent any electrical hazards during subsequent use.

Step 6: High-Level Disinfection

Prepare High-Level Disinfectant:

Follow the manufacturer's guidelines to prepare the high-level disinfectant solution in a basin or automated disinfector. Ensure the solution is at the correct temperature and concentration.

Soak in High-Level Disinfectant:

Submerge the probe shaft in the high-level disinfectant for the required contact time, monitoring the process to ensure compliance with the disinfectant’s Instructions for Use (IFU).

Step 7: Rinse and Final Dry

Rinse with Clean Water:

After disinfection, rinse the probe thoroughly with water to remove any disinfectant residue. Use a new low-lint cloth to dry the probe completely.

?

Step 8: Storage

Store in a Clean Environment:

Place the disinfected, dried, and tested probe in a clean storage cabinet designed to keep the probe vertically and freely hanging. Ensure that HEPA filtered air bathes the probes if available to maintain HLD.

?

Step 9: Documentation

Record Keeping:

Document each step of the reprocessing procedure, including times, solutions used, and personnel involved, to ensure compliance with regulatory standards and facilitate traceability.

?

Conclusion

Reprocessing TEE/TOE ultrasound probes during unit or process downtime requires meticulous adherence to infection control protocols and manufacturer’s instructions. By following these steps, facilities can ensure patient safety and maintain high hygiene standards even when faced with unexpected challenges. Always have a contingency plan in place, train your staff regularly, and review your protocols to stay prepared for any situation.
