Caution: Always withdraw stylet back beyond catheter tip prior to
insertion.
INSERTION
1. Maintaining sterility, access target vein with introducer needle/
catheter.
•
Apply tourniquet to arm.
• Perform the venipuncture, and confirm entry into vein by
observing for a flashback of blood.
• Holding the needle stationary, advance the introducer sheath
into the vein by pushing forward.
Caution: Never reinsert the needle into the introducer as this could
shear or sever the introducer.
• Release the tourniquet. Support the introducer to avoid
displacement. Apply digital pressure on the vessel, above the
introducer tip, to minimize blood flow.
• Withdraw the needle from the introducer sheath. Dispose of any
unshielded needles immediately.
2. Insert distal tip of the catheter into and through the introducer
sheath until the catheter tip is correctly positioned.
3. Stabilize the catheter position by applying pressure to the vein
proximal to the inserion site.
4. Remove the tear-away sheath by slowly pulling it out of the
vessel while simultaneously splitting the sheath by grasping
the tabs and pulling them apart (a slight twisting motion may
be helpful).
Caution: Do not pull apart the portion of the sheath that remains
in the vessel. To avoid vessel damage, pull back the sheath as far as
possible and tear the sheath only few centimeters at a time.
5. Make any adjustments to catheter under fluoroscopy. The distal
tip should be positioned at the level of the caval atrial junction.
Caution: Do not clamp the lumen portion of the catheter. Clamp
only the extension(s). Do not use the serrated forceps, use only the
in-line clamp(s) provided.
6. Remove the stylet by applying gentle pressure with one hand
above the insertion site while grasping the stylet with the other
hand and slowly pulling back with a constant motion. Remove
sideport adapter and replace with needleless access port or
injection cap. Attach saline filled syringe to catheter, aspirate
lumen and then irrigate with saline. If using needleless access
port, remove syringe prior to clamping extension.
Caution: If difficulty and/or bunching of the catheter lumen are
experienced while removing the stylet, additional flushing of the
catheter may be helpful. The catheter may need to be repositioned
to allow for removal of the stylet.
Caution: Do not attempt to reinsert stylet once it has been
withdrawn.
Caution: Never leave stylet in place after catheter insertion; injury
may occur. Remove both stylet and sideport adapter after insertion.
Caution: Small syringes will generate excessive pressure and may
damage the catheter. Ten (10cc) or larger syringes are
recommended.
7. Confirm and document proper tip placement by x-ray before
using the catheter.
