Treatment for Blisters Around an Intravenous (IV) Line Site

Assessment and Immediate Management

  • The Centers for Disease Control and Prevention recommends removing the peripheral venous catheter immediately if blisters, pain, induration, erythema, or any exudate is present at the insertion site 1, 2
  • Submit any exudate from the insertion site for Gram staining and culture, particularly in immunocompromised patients 1
  • Evaluate the extent of tissue damage, as blisters may indicate infiltration or extravasation of IV fluids or medications 2

Treatment Based on Severity

  • Clean the area with an appropriate antiseptic (2% chlorhexidine-based preparation preferred, or 70% alcohol) 2
  • Apply sterile dressing appropriate to the condition of the site, such as sterile gauze dressing for weeping/oozing sites or transparent semi-permeable dressing for dry sites 2
  • Monitor the site daily for signs of improvement or deterioration 2

Prevention of Future Occurrences

  • Select catheters based on intended purpose and duration of use 2
  • Avoid steel needles for administration of fluids and medications that might cause tissue necrosis if extravasation occurs 3, 4
  • For adults, use upper extremity sites rather than lower extremity sites for catheter insertion 5
  • Replace peripheral venous catheters at least every 72-96 hours in adults 2
  • Evaluate catheter insertion sites daily through visual inspection if transparent dressing is used or by palpation if opaque dressing is used 5

Common Pitfalls to Avoid

  • Do not delay removal of the catheter if complications are suspected 1
  • Avoid placing new catheters in the same area where blisters or other complications have occurred 5
  • Do not routinely apply prophylactic topical antimicrobial or antiseptic ointment to insertion sites of peripheral venous catheters 2
  • Do not submerge the affected area in water until healing is complete 2
