Probes and Biopsy
20.12.3 Disinfecting Probes
Ultrasound probes can be disinfected using liquid chemical germicides. The level of disinfection is
directly related to the duration of contact with the germicide. Increased contact time produces a higher
level of disinfection.
Cidex and Sporox are the only germicides approved by GE Medical Systems for Ultrasound probe
disinfecting purposes. 2% Glutaraldehyde-based solutions (Cidex) have been shown to be very
effective for disinfecting.
Please consider our constantly updated Care-Card (which is inside the transducer boxes) for
compatible disinfectants and gels !

In order for liquid chemical germicides to be effective, all visible residue must be
removed during the cleaning process. Thoroughly clean the probe, as described
earlier, before attempting disinfection.
1. Prepare the germicide solution according to the manufacturer's instructions. Be sure to follow all
precautions for storage, use and disposal.
2. Place the cleaned and dried probe in contact with the germicide for the time specified by the
germicide manufacturer. High-level disinfection is recommended for surface probes and is
required for endocavitary and intraoperative probes (follow the germicide manufacturer's
recommended time).
3. After removing from the germicide, rinse the probe following the germicide manufacturer's
rinsing instructions. Flush all visible germicide residue from the probe and allow to air dry.
CREUTZFIELD-JACOB DISEASE
Neurological use on patients with this disease must be avoided.
If a probe becomes contaminated, there is no adequate disinfecting means.
