Management of Edema and Phlebitis at IV Site

Remove the peripheral venous catheter immediately when edema and phlebitis are identified. 1, 2

Immediate Actions

Catheter removal is mandatory when signs of phlebitis develop, including warmth, tenderness, erythema, palpable venous cord, or edema. 1 The CDC provides a Category IB recommendation (strong evidence) that leaving the catheter in place increases risk of progression to septic phlebitis and bloodstream infection. 1, 2

After Removal:

  • Apply heat and elevation to the affected extremity to reduce inflammation and promote venous drainage. 3
  • Do NOT apply topical antimicrobial ointments or creams to the phlebitis site—this provides no benefit and may promote fungal infections and antimicrobial resistance. 1, 2

Daily Monitoring Requirements

Evaluate the phlebitis site daily for the following progression indicators: 2

  • Increasing tenderness, erythema, warmth, or swelling 2
  • Signs of infection: fever, purulent drainage, systemic symptoms 2
  • Development of palpable venous cord indicating thrombophlebitis 1

When to Escalate Treatment

Initiate antibiotics and consider surgical excision if any of the following occur: 3

  • Clinical deterioration despite conservative management 3
  • Persistent septicemia after 24 hours of antibiotic therapy 3
  • Development of systemic signs of infection 3

Septic phlebitis carries a 56% complication rate with an average 14-day hospital stay after diagnosis, making early recognition critical. 3 Staphylococcus aureus (41%) and Group A streptococcus (20%) are the most common causative organisms. 3

Future IV Access Strategy

Use upper extremity sites exclusively for subsequent peripheral IV access. 1, 2 Lower extremity placement significantly increases phlebitis risk in adults and should be avoided. 1

Consider a midline catheter or PICC if IV therapy duration will exceed 6 days, as these have substantially lower phlebitis rates (0.3% for midlines vs. 2.3-53.4% for peripheral IVs). 1, 4, 5, 6, 7

For Short Peripheral Catheters:

  • Replace every 72-96 hours in adults to prevent recurrent phlebitis. 1, 4, 7
  • In children, leave in place until IV therapy is completed unless complications develop. 1, 4

Critical Pitfalls to Avoid

  • Never leave the catheter in place hoping phlebitis will resolve with treatment alone—removal is non-negotiable. 1, 2
  • Avoid insertion sites around the elbow joint for future access, as these carry increased phlebitis risk. 8
  • Do not use steel needles for medications that could cause tissue necrosis if extravasation occurs. 1
  • Avoid contaminated dressings and ensure proper aseptic technique, as these are significant risk factors for phlebitis development. 6
