If you use Cidex OPA Solution (Cidex OPA), residual solution may remain on
your transducers if you do not carefully follow the manufacturer’s instructions.
Residual Cidex OPA on TEE transducers may cause the following:
• Temporary staining of the mouth and lip area
• Irritation or chemical burns of the mouth, throat, esophagus, and stomach
To minimize the effects from residual Cidex OPA, or any other disinfectant,
Philips recommends that you
• Follow the disinfectant manufacturer’s instructions very carefully. For exam-
ple, the manufacturer of Cidex OPA recommends soaking transducers three
times in fresh water.
• Use a protective transducer cover during endocavity and TEE examinations.
• Use a sterile protective transducer cover with sterile ultrasound transmission
gel during intraoperative and biopsy examinations.
• 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).
➤ To disinfect a TEE transducer by immersion
1. Disconnect the transducer from the system.
2. Use the following procedure to remove all organic matter and other residue:
a. Soak gauze pads in mild, soapy water. Do not use iodine-based soaps.
b. Do either of the following:
• Wipe the distal tip and flexible shaft up to the control housing (steer-
ing mechanism) with the gauze pads.
• Use an enzymatic cleaner to assist in removing protein residuals. Enzy-
matic cleaners should have a pH of 6.0 to 8.0. These cleaners are fur-
ther diluted during use. Follow the manufacturer’s instructions for
dilution.
