Proper Procedure for Changing a PICC Dressing

Preparation and Hand Hygiene

  • The American College of Radiology recommends hand hygiene procedures, including washing hands with conventional soap and water or alcohol-based hand rubs, must be performed before and after all catheter-related interventions 3, 4
  • Maximal sterile barrier precautions, including cap, mask, sterile gown, sterile gloves, and a sterile drape, should be used for dressing changes, as recommended by Clinical Nutrition 1, 3

Skin Antisepsis

  • The American College of Cardiology and Clinical Infectious Diseases recommend preparing the skin with a 0.5-2% chlorhexidine preparation with alcohol (2% chlorhexidine gluconate in 70% isopropyl alcohol is preferred) 1, 2, 5
  • If there is a contraindication to chlorhexidine, alternatives such as tincture of iodine, an iodophor, or 70% alcohol may be used, as suggested by Clinical Infectious Diseases and Clinical Nutrition 2, 5

Dressing Selection and Application

  • Sterile gauze or sterile, transparent, semi-permeable dressings should be used to cover the catheter site, as recommended by Clinical Infectious Diseases and Clinical Nutrition 2, 6
  • For the first 1-2 days after insertion, placement of sterile gauze between the PICC entry site and adhesive dressing is appropriate, according to Annals of Internal Medicine 7, 8

Dressing Change Frequency

  • Gauze dressings should be replaced every 2 days for short-term CVCs, as recommended by Clinical Infectious Diseases and Clinical Nutrition 2, 10
  • Transparent dressings should be replaced at least every 7 days, according to Clinical Infectious Diseases and Clinical Nutrition 2, 10

Catheter Stabilization

  • Manufactured catheter stabilization devices should be used rather than sutures to secure the catheter whenever feasible, as recommended by Clinical Nutrition 1

Additional Considerations

  • Topical antibiotic ointment or creams should not be applied on insertion sites, as they may promote fungal infections and antimicrobial resistance, according to Clinical Infectious Diseases and Clinical Nutrition 2, 6
  • Chlorhexidine-impregnated dressings may be considered for patients with short-term catheters who are at high risk for infection, as suggested by Clinical Infectious Diseases and Clinical Nutrition 2, 10

Common Pitfalls and Caveats

  • The catheter or catheter site should never be submerged in water, and showering may be permitted with appropriate precautions, according to Clinical Infectious Diseases 2
  • Organic solvents (e.g., acetone, ether) should not be used on the skin before or after applying antiseptic, as recommended by Clinical Nutrition 1
  • A migrated PICC should never be advanced, and guidewire exchange is the appropriate approach if the PICC needs to remain in place, according to Annals of Internal Medicine 8, 9
  • Daily skin cleansing with a 2% chlorhexidine-impregnated wash cloth may help reduce the risk of catheter-related bloodstream infections, as suggested by the Journal of the American College of Radiology 3, 4
