2. Fill the syringe with 5 mL of a heparinized solution (if not contraindicated).
3. Enter the catheter access port as described in "Vascular applications only" on
page 31.
4. Gently alternate irrigation and aspiration to open the catheter.
5. If resistance continues, aspirate as much fluid as possible from the catheter access port.
Use a 1-mL tuberculin syringe, stopcock, and catheter access port needle and inject 0.5
mL of heparinized solution (1000 U/mL) to lightly pressurize the system. Close the
stopcock, and remove the needle.
#
Caution: When clearing a catheter occlusion, do not inject more than 0.5 mL of
fluid into the catheter access port. Injection of more than 0.5 mL may cause
catheter damage or disconnection, allowing leakage into surrounding tissue,
resulting in tissue damage or a loss of or change in therapy.
6. Check for catheter patency in 10 minutes using a 10-mL syringe filled with 5 mL of
heparinized solution (1000 U/mL). Lightly pressurize the syringe and wait 10–15
seconds to observe for loss of resistance. Do not force infusion.
7. If the catheter remains occluded, aspirate through the catheter access port to remove
the original 0.5 mL of heparinized solution.
8. Repeat step 5 or steps 4 and 5 using 0.5 mL of heparinized solution or streptokinase
(refer to drug labeling for complete instructions) and wait 10 to 30 minutes before
checking for catheter patency. Attempt to dislodge the clot before flushing.
