Dressing changes:

How often

The dressing should be changed at least 2-3 times/week If the dressing becomes wet, soiled or loose, it should be changed more frequently.

How to change a dressing

  1. Wash hands thoroughly
  2. Put on examination gloves and a face mask
  3. Remove the old dressing, making sure not to remove the catheter
  4. Inspect catheter for kinks, cracks, or leaks. Confirm sutures remain intact. Examine skin for redness, swelling, induration, or drainage.
  5. Remove the examination gloves
  6. Open packages of sterile gloves, sterile gauze, Tegaderm, and betadine swabs. Put on sterile gloves
  7. Clean site with betadine and allow to air dry. Then remove betadine using alcohol swabs
  8. Place a sterile 2x2 inch gauze on catheter exit site
  9. Apply Tegaderm to site
  10. Confirm the catheter is not kinked by dressing and that the arm has good mobility with the new dressing

Catheter Maintenance

  • Catheter must be capped when not in use. Make certain caps are tight and that there are no cracks in the catheter or cap. If there is a crack, notify Angiography/Interventional Radiology immediately
  • If line also has a clamp on the catheter this should also be closed whenever line is not in use
  • The catheter should be taped to the skin so it is not going to be pulled on or damaged
  • Each lumen should be flushed at least once a day. Flush is 10cc of normal saline followed by 2 cc of heparin flush (100 units heparin per cc of normal saline).
  • Each lumen should be flushed with 10cc normal saline before use.
  • After use the catheter should be flushed with normal saline and heparin flush as described above
  • If the catheter is on continuous infusion it still should have flushing with normal saline and heparin at least once per day
  • The line can be used for blood draws. A 5 cc discard should first be removed from the line. Flushing with normal saline and heparin as described above should be done after each blood draw

Safety Precautions

  • The catheter must be capped whenever it is not in use. If catheter also has a clamp it should be used as well.
  • If catheter is partially pulled out, do not attempt to reinsert it. If catheter falls out completely, apply gentle pressure to the entry site for 10 minutes.
  • If catheter appears damaged or is leaking, it must not be used. Place a clamp near the skin entry site and call angiography/Interventional Radiology
  • Fevers, or changes at the catheter entry site such as redness, swelling, drainage, or tenderness should be reported to a physician.
  • Call Angiography/Interventional Radiology if catheter will not allow aspiration of blood.
  • Call Angiography/Interventional Radiology if arm or neck swelling develop.
  • Call Angiography/Interventional Radiology at 924-9401 with any questions or problems. After hours call the radiology department at 924-9400 and ask to speak to the Angiography/Interventional fellow on call.
