•
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 clamps provided or smooth jawed
hemostat.
•
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.
1.
Draw heparin in two syringes, corresponding to the amount
designated on each catheter lumen. Assure that the syringes are
free of air.
2.
Remove end caps from the arterial venous extension luers.
3.
Attach a syringe containing heparin solution to the female luer of
each arterial venous extension.
4.
Open extension clamps.
5.
Aspirate to insure that no air will be forced into the patient.
6.
Inject heparin into each catheter using quick bolus technique.
Note:
Each lumen should be completely filled with heparin to ensure
effectiveness.
7.
Close extension clamps.
Caution:
Extension clamps should only be open for aspiration,
flushing, and dialysis treatment.
8.
Remove syringes.
9.
Attach a sterile end cap onto the female luers of the arterial venous
extension.
•
In most instances, no further heparin is necessary for 48-72 hours,
provided the catheters have not been aspirated or flushed.
•
Clean skin around catheter. Cover the exit site with occlusive
dressing and leave extensions, clamps, arterial and venous
extensions, and caps exposed for access by staff.
•
Wound dressing must be kept clean and dry.
Caution:
Patients must not swim, shower, or soak dressing while
bathing.
•
If profuse perspiration or accidental wetting compromises adhesion
of dressing, the medical or nursing staff must change the dressing
under sterile conditions.
