Caution: Always review hospital or unit protocol, potential
complications and their treatment, warnings, and precautions prior
to catheter removal.
1.
Palpate the catheter exit tunnel to locate the cuff.
2. Administer sufficient local anesthetic to exit site and cuff
location to completely anesthetize the area.
3.
Cut sutures from suture wing. Follow hospital protocol for
removal of skin sutures.
4.
Make a 2cm incision over the cuff, parallel to the catheter.
5.
Dissect down to the cuff using blunt and sharp dissection as
indicated.
6.
When visible, grasp cuff with clamp.
7.
Clamp catheter between the cuff and the insertion site.
8.
Cut catheter between cuff and exit site. Withdraw internal
portion of catheter through the incision in the tunnel.
9.
Remove remaining section of catheter (i.e., portion in tunnel)
through the exit site.
Caution: Do not pull distal end of catheter through incision as
contamination of wound may occur.
10. Apply pressure to proximal tunnel for approximately 10-15
minutes or until bleeding stops.
11. Suture incision and apply dressing in a manner to promote
optimal healing.
12. Check catheter integrity for tears and measure catheter when
removed. It must be equal to the length of catheter when it was
inserted.
