transducer can result in lacerations, bleeding, perforation, tearing of
adhesions, and ligament damage. Also be aware that the tip can fold over,
causing similar damage.
• Refrain from handling the distal tip whenever possible. If you must handle
the distal tip, grasp it on the sides. Do not touch the top or bottom. Support
the transducer’s proximal head, either by having an assistant hold the
steering mechanism or by clamping the transducer at the steering
mechanism. Ensure that the clamp does not interfere with steering, and do
not clamp any part of the flexible shaft, as this will damage the transducer.
Tip Fold-Over
On rare occasions, the tip of a TEE transducer has folded over during insertion.
The effects can be serious if the situation is handled incorrectly. The esophagus
can be scraped, perforated, or otherwise damaged.
For more information on tip fold-over, see "Tip Fold-Over" in the Help.
Recognizing Tip Fold-Over
The TEE transducer tip might be folded over in the patient if you encounter any
of the following:
• Resistance to advancing or removing the transducer
• An inability to turn the control knobs
• Fixation of the control knobs in the maximum flexion position
• Extreme difficulty in obtaining an image
Correcting Tip Fold-Over
If you suspect the transducer tip is folded over, Philips' physician consultants
recommend that you gently try to manipulate the transducer. If the tip is neither
locked nor jammed in a doubled-over position, and you can move it forward,
advance the transducer into the stomach. Then straighten the tip and remove
the transducer.
