AMT Bridle Standard, Directions, Indications, & Contraindications For Use

Page: 8 / 112

NOTE: It is preferred to have the patient arranged in supine position
prior to placement. The AMT Bridle
™
may be placed before or after
the nasal tube. Important: Lubricate the probe, catheter and
umbilical tape. Insert the blue probe into nostril opposite the nasal
tube until the first rib is at the bottom of nostril. Make adjustment
for smaller patients.
Insert the flexible AMT Bridle
™
catheter into the opposite nostril to
approximate the magnets. Pull back on the orange stylet about 1cm
(1/2”) until the magnets connect. The “click” of the magnets may be
heard or felt. Equal lengths of both probes (minus the orange stylet)
should be exposed.
NOTE FOR PEDIATRIC PATIENTS: Magnet connection may be
more difficult for pediatric patients due to the smaller area for probe
manipulation or due to soft tissue constraints related to the patient’s
intranasal anatomy.

NOTE FOR PEDIATRIC PATIENTS: It is recommended that the
AMT Bridle ™ is placed prior to the nasal tube for pediatric patients.
Placement of the AMT Bridle
™
after the nasal tube may be possible,
but will be more difficult due to the limited intranasal area.
NOTE: The stylet and catheter should be inserted along the floor
of the nostril.

Standard Directions For Use

If necessary, gently twist the probes from side to side and/
or up and down to encourage contact between the magnets.
If no contact has occurred, then advance both the flexible
catheter and the probe. Important: Once contact has occurred,
remove the orange stylet completely from the flexible catheter.
WARNING: Moving or non-cooperative (especially pediatric) patients
may cause additional risks during placement. Nasal anesthetic
spray may be used to ease patient comfort, in these cases please
consult physician. If appropriate, sedation may be used to assist
placement.
Slowly withdraw the probe and allow the flexible catheter to
advance through the nose. Continue until only cloth umbilical tape
is completely pulled up and through one nostril and at least a couple
inches outside the opposite nostril. This creates a loop or “bridle”
around the vomer bone. If the cloth umbilical tape does not advance
out of the opposite nostril, remove catheter, replace the stylet and
start over at Step 1.

Cut the flexible catheter portion from the umbilical tape. Dispose of
catheter and probe. If the nasal tube has not been placed, insert now
per the nasal tube manufacturer’s instructions.
Important: Slide clip up umbilical tape and into position. Clip
should be located close to nostril, approximately 1cm (1/2”) or one
“finger width” from nostril.
NOTE: The clip should not touch the nostril. Place the nasal tube
into the clip’s channel or groove.
