What is the first-line treatment for phlebitis after an Intravenous (IV) catheter placement?

First-Line Treatment for Phlebitis After an IV

The first-line treatment for phlebitis after an IV catheter is removal of the peripheral venous catheter and application of warm compresses to the affected site. 1, 2

Initial Management

1. Remove the peripheral venous catheter immediately

   • CDC guidelines explicitly recommend removing peripheral venous catheters if the patient develops signs of phlebitis (warmth, tenderness, erythema, and palpable venous cord) 1
   • This is a Category IB recommendation, indicating strong recommendation supported by some experimental, clinical, or epidemiological studies

2. Apply warm compresses to the affected area

   • Warm water compresses (approximately 28°C) should be applied for 15 minutes, three times daily 3
   • Research shows warm compresses are effective in reducing phlebitis symptoms including redness, edema width, and pain intensity 3
   • This intervention is both effective and inexpensive 4

Assessment of Phlebitis

When evaluating a patient with suspected phlebitis:

• Look for cardinal signs:

  • Warmth at the insertion site
  • Tenderness along the vein
  • Erythema (redness)
  • Palpable venous cord
  • Pain at the site
  • Swelling

• Use a standardized phlebitis scoring system to grade severity 5

Additional Management Considerations

• Documentation: Record the occurrence of phlebitis, interventions performed, and patient response
• Monitoring: Continue to assess the site for 48 hours after catheter removal, as post-infusion phlebitis can develop within 24 hours after catheter removal 6
• New IV access: If continued IV therapy is required, place a new catheter at a different site (preferably in the opposite limb)
• Elevation: Elevate the affected limb if possible to reduce swelling

Prevention Strategies

To prevent future episodes of phlebitis:

• Replace peripheral venous catheters in adults every 72-96 hours 2
• Select appropriate catheter size and type based on therapy duration and solution characteristics 2
• Use upper extremity sites rather than lower extremity sites for catheter insertion 1
• Evaluate catheter insertion sites daily 1
• Consider midline catheters for IV therapy expected to exceed 6 days 2
• Clean injection ports with 70% alcohol or an iodophor before accessing the system 2

Important Caveats

• Do not routinely apply prophylactic topical antimicrobial or antiseptic ointment or cream to the insertion site of peripheral venous catheters (Category IA recommendation) 1
• Avoid the use of steel needles for the administration of fluids and medication that might cause tissue necrosis if extravasation occurs 1
• If phlebitis is suspected to be infectious in nature, monitor for systemic signs of infection and consider obtaining cultures if appropriate

By promptly removing the catheter and applying warm compresses, most cases of phlebitis will resolve within a few days without further complications.
