4. Advance the catheter tip into the vessel.
5. Withdraw the vein pick, if used.
6. Advance the catheter into the vessel to the desired infusion site.
Note: Catheters should be positioned with the catheter tip at the
junction of the superior vena cava and the right atrium. Verify
correct catheter tip position, using fluoroscopy, or appropriate
technology. Do not occlude or cut catheter when using sutures to
secure catheter.
PERCUTANEOUS PROCEDURE
1. Place patient in the Trendelenburg position with head turned away
from the intended venipuncture site.
2. Locate desired vessel using a small gauge needle attached to a
syringe. Refer to the "Warnings" section covering catheter Pinch-off,
if inserting the catheter via the subclavian vein.
3. Attach introducer needle to the syringe and insert into vessel along-
side the small gauge needle. Remove small gauge needle.
4. Aspirate gently as the insertion is made. If the artery is entered,
withdraw the needle and
minutes. If the pleural space is entered, withdraw the needle and
evaluate patient for possible pneumothorax.
5. When the vein has been entered, remove the syringe leaving
the needle in place. Place a finger over the hub of the needle to
minimize blood loss and the risk of air aspiration. The risk of air
aspiration is reduced by performing this part of the procedure with
the patient performing the Valsalva maneuver.
6. If using a micropuncture set, insert the flexible end of the guidewire
into the needle. Advance the guidewire as far as appropriate.
Verify correct positioning, using fluoroscopy or ultrasound. Gently
withdraw and remove the needle, while holding the guidewire in
position.
Caution: If the guidewire must be withdrawn while the needle is
inserted, remove both needle and wire as a unit to prevent the
needle from damaging or shearing the guidewire. Advance the small
sheath and dilator together as appropriate. Withdraw the dilator
and guidewire, leaving the small sheath in place.
Warning: Place a thumb over the orifice of the sheath to minimize
blood loss and risk of air embolism.
7. Straighten "J" tip of guidewire with tip straightener and insert
tapered end of tip straightener into the needle.
8. Remove the tip straightener and advance the guidewire into the
superior vena cava. Advance the guidewire as far as appropriate
for the procedure. Verify correct positioning, using fluoroscopy, or
appropriate technology.
