Philips iE33 - Disinfection of Transducers by Immersion (High-Level Disinfection)

Disinfection of Transducers by Immersion (High-Level
Disinfection)
Methods for disinfecting transesophageal (TEE) and non-TEE transducers differ.
Observe the following warnings and cautions and then see the procedure for
your transducer. For non-TEE transducers, see "Disinfecting Transducers by
Immersion" on page 310. For TEE transducers, see "Disinfecting TEE Transducers
by Immersion" on page 311 or "Disinfecting TEE Transducers in an Automated
Disinfector" on page 315.
WARNINGS
• If a premixed disinfectant is used, be sure to observe the expiration date.
• If you use Cidex OPA Solution or other OPA-based disinfectants, residual
solution may remain on your transducers if you do not carefully follow the
manufacturer’s instructions. Residual OPA on TEE transducers may cause
temporary staining of the mouth and lip area and irritation or chemical
burns of the mouth, throat, esophagus, and stomach.
WARNINGS
To minimize the effects from residual OPA, or any other disinfectant, Philips
recommends the following:
• Follow the disinfectant manufacturer’s instructions very carefully. For
example, the manufacturer of Cidex OPA recommends soaking transducers
three times in fresh water.
• Use a protective transducer cover during endocavity and TEE studies.
• Use a sterile protective transducer cover with sterile ultrasound
transmission gel during intraoperative and biopsy studies.
• Limit the time that transducers are soaked in the disinfectant solution to
the minimum time recommended by the disinfectant manufacturer (for
example, the manufacturer of Cidex OPA recommends a minimum of
12 minutes).
