VI. Catheter Securement and Wound Care
An attachable suture wing
is provided to suture the catheter at the exit site. Squeeze lightly
the attachable suture wings to open the split underside of the suture wing body. Place the
suture wing at the catheter size mark at the exit site and release. Secure wing by suturing it in
place through the holes provided.
Suture insertion and exit sites closed. Next, suture the catheter adapters to the skin using the
suture wing. Do not suture the catheter tubing.
Caution: Avoid nicking catheter during suturing.
Caution: Sharp objects may cause catheter failure due to punctures or cuts in the catheter
lumen.
Cover the insertion and exit sites with occlusive dressings.
Record catheter length and catheter lot number on patient’s chart.
HEPARINIZATION
Follow catheter patency guidelines if the catheter is not to be used immediately for treatment.
To maintain patency between treatments, create a heparin lock in each lumen of the catheter.
Follow hospital protocol for heparin concentration.
Draw heparin into two syringes, corresponding to the amount designated on the arterial and
venous extensions. Assure that the syringes are free of air.
Remove injection caps from the extensions.
Attach a syringe containing heparin solution to the female luer of each extension.
Open extension clamps.
Caution: Aspirate to insure that no air will be forced into the patient.
Inject heparin into each lumen using quick bolus technique.
Caution: Each lumen should be completely filled with heparin to ensure effectiveness.
Close extension clamps.
Caution: Extension clamps should only be open for aspiration, flushing, and dialysis treat-
ment.
Remove syringes.
Attach a sterile injection cap onto the female luers of the extensions.
Tape injection caps to prevent accidental removal.
Heparin is not necessary for the next 48 to 72 hours, provided that the lumens have not been
aspirated or flushed
.
HEMODIALYSIS TREATMENT
Caution: To avoid air embolism, keep the extension tubing clamped at all times, when not
in use.
Caution: To prevent systematic heparinization, the heparin solution must be removed from
each lumen prior to patient treatment.
