18. Attach syringes to both extensions and open clamps. Blood should
aspirate easily from both arterial and venous sides. If either side
exhibits excessive resistance to blood aspiration, the catheter may
need to be rotated or repositioned to obtain adequate blood flows.
19. Once adequate aspiration has been achieved, both lumens should
be irrigated with saline filled syringes using quick bolus technique.
Assure that extension clamps are open during irrigation procedure.
20. Close the extension clamps, remove the syringes, and place an end
cap on each luer lock connector. Avoid air embolism by keeping
extension tubing clamped at all times, when not in use, and by
aspirating then irrigating the catheter with saline prior to each use.
With each change in tubing connections, purge air from the
catheter and all connecting tubing and caps.
21. To maintain patency, a heparin lock must be created in both
lumens. Refer to hospital heparinization guidelines
Caution:
Assure that all air has been aspirated from the catheter and
extensions. Failure to do so may result in air embolism.
22. Once the catheter is locked with heparin, close the clamps and
install end caps onto the extensions' female luers.
23. Confirm proper tip placement with fluoroscopy. The distal venous
tip should be positioned at the level of the caval atrial junction or
into the right atrium to ensure optimal blood flow (as
recommended in current NKF DOQI Guidelines).
Note:
Femoral catheter tip placement is recommended at the junction
of the iliac vein and the inferior vena cava.
Caution:
Failure to verify catheter placement may result in serious
trauma or fatal complications.
CATHETER SECUREMENT AND WOUND DRESSING:
24. Suture insertion site closed. Suture the catheter to the skin using
the suture wing. Do not suture the catheter tubing.
Caution:
Care must be taken when using sharp objects or needles in
close proximity to catheter lumen. Contact from sharp objects may
cause catheter failure.
25. Cover the insertion and exit site with an occlusive dressings.
26. Catheter must be secured/sutured for entire duration of
implantation.
27. Record catheter length and catheter lot number on patient's chart.
•
The heparin solution must be removed from each lumen prior to
treatment to prevent systemic heparinization of the patient.
Aspiration should be based on dialysis unit protocol.
•
Before dialysis begins all connections to catheter and extracorporeal
circuits should be examined carefully.
•
Frequent visual inspection should be conducted to detect leaks to
prevent blood loss or air embolism.
•
If a leak is found, the catheter should be clamped immediately.
Caution:
Only clamp catheter with in-line clamps provided.
•
Necessary remedial action must be taken prior to the continuation
of the dialysis treatment.
Note:
Excessive blood loss may lead to patient shock.
•
Hemodialysis should be performed under physician's instructions.
•
If the catheter is not to be used immediately for treatment, follow
the suggested catheter patency guidelines.
•
To maintain patency between treatments, a heparin lock must be
created in each lumen of the catheter.
