Aspirate and irrigate the catheter with saline prior to each use. Purge any air from the catheter
and all connecting tubing and caps upon tubing connection changes.
Aspiration procedure should comply with dialysis unit protocol.
Before beginning dialysis, check all catheter connections and extracorporeal circuits carefully.
Caution: Always tape luer locks to bloodlines during treatment to safeguard against ac-
cidental disconnection.
Visually inspect the catheter and its connections for signs of leakage to prevent blood loss
or air embolism. If necessary, take remedial action prior to the continuation of the dialysis
treatment.
Caution: Excessive blood loss may lead to patient shock.
Hemodialysis should be performed under physician’s instructions.
POST DIALYSIS
Prepare syringes with sterile normal saline and heparin.
Stop the blood pump. Close the clamp on the arterial extension. Clamp the arterial bloodline
at the connection site.
Disconnect the arterial bloodline from the adapter of the catheter and connect a syringe filled
with sterile normal saline to the arterial adapter. Open the clamp on the arterial extension and
flush the blood from the arterial lumen of the catheter. Reclamp the extension.
Heparinize the lumen with the appropriate volume/concentration of heparin (see above).
Rinse back the blood in the extra-corporeal circuit via the venous lumen.
After rinsing back the patient’s blood, turn the blood pump off. Clamp the venous extension
and disconnect the venous bloodline from the venous adapter of the catheter.
Connect a syringe filled with sterile normal saline to the venous adapter. Open the clamp on
the venous extension and flush all remaining blood from the venous lumen of the catheter.
Reclamp and then heparinize the lumen with the appropriate volume/concentration of
heparin.
Ensure that the clamps are closed on both extensions. Remove syringes and attach an injec-
tion sealing cap to each adapter. Tape the injection sealing caps to the extensions to prevent
accidental removal.
WARNING
Keep the catheter clamped at all times except when connected to bloodlines or syringe
during treatment.
