Sonic Cleaning Surgical Instruments in Veterinary Clinics

Removing contaminants from surgical instruments used in veterinary clinics is best accomplished with an ultrasonic cleaning procedure similar to recommendations by the World Health Organization for infection control in healthcare facilities – that is cleaning, then disinfecting or sterilizing. Surgical instruments sonic cleaning employs the power of cavitation to dislodge contaminants difficult if not impossible to remove by manual scrubbing. Minute cavitation bubbles created by the ultrasonic cleaner’s generator powered transducers reach all instrument surfaces immersed in the solution to thoroughly remove contaminants.*

Selecting a Sonic Surgical Instrument Cleaner

Several models of ultrasonic cleaners are suitable for a veterinary clinic instrument cleaning cycle. A basic unit is the 43 kHz 3.25 gallon capacity LR 725 cleaner that can accommodate instruments to 15 inches in length and comes with an on-off switch and timer. Another is the 3.75 gallon 37 kHz Elmasonic S375ELthat can accommodate slightly longer instruments. In addition to an on-off switch and timer it has a degas feature to remove air from fresh cleaning solutions and a sweep mode to provide uniform cleaning action throughout the bath.

How to Clean Veterinary Clinic Surgical Equipment

The first step is preparing the cleaning solution. We recommend MedClean C7, an enzymatic alkaline liquid detergent concentrate especially formulated to remove blood, tissue and other contaminants associated with surgical instruments. Add water (deionized recommended) to the ultrasonic cleaner tank and MedClean C7 at 1-3 ounces per gallon. Turn on the ultrasonic cleaner to mix and degas the solution, a step necessary each time a new solution is prepared. For the LR 725 ultrasonic cleaner this should take approximately 10 minutes; for the S375EL activate the degas mode. You are now ready to clean.

The Association of periOperative Registered Nurses (AORN) recommends removing gross contaminants before cleaning surgical instruments. This helps prolong the ultrasonic cleaning solution, but should be done carefully to avoid injury. Immediately soak the instruments in a disinfectant. This avoids biological contaminants drying on them, which will make them much more difficult to clean.

A typical cleaning procedure:p>

1. Carefully position instruments in the cleaning tray. They should not contact each other.

2. Immerse the basket in the cleaning solution and set the timer for 10 minutes.

3. When finished inspect the instruments then rinse them in DI or distilled water to avoid water spotting. They are ready for disinfecting or sterilizing according to veterinary practice.

3. Rinse the restraint devices in hot water and arrange in the ultrasonic cleaner’s basket. Lower the basket into the solution and set the timer for 10 minutes.

Cleaning solutions should be replaced frequently again according to veterinary practice. Drain the tank and dispose of the solution according to local regulations. Clean the tank following instructions in the user manual. You are now ready to prepare a new cleaning bath.
