Management of Blisters in Second-Degree Partial Thickness Burns

Initial Management

  • The American Heart Association recommends immediately cooling the burn with clean running water for 5-20 minutes to limit tissue damage and reduce pain 1, 3
  • Remove any jewelry from the affected area before swelling occurs to prevent constriction and vascular compromise, as suggested by the American College of Cardiology 3
  • Administer over-the-counter pain medications such as acetaminophen or NSAIDs for pain management, according to the American Heart Association 1, 2

Blister Management

  • Intact blisters should be loosely covered with a clean cloth or nonadherent dry dressing, as recommended by the American Heart Association 1, 2
  • The British Association of Dermatologists suggests preserving the blister roof as a biological dressing to help with pain management and promote healing 5

Rationale for Preserving Blisters

  • Preserving the blister roof as a biological dressing helps with pain management and promotes healing, according to the British Association of Dermatologists 5
  • Keeping blisters intact reduces the risk of infection by maintaining a natural barrier, as recommended by the American College of Physicians 4

Proper Technique for Blister Management

  • The British Association of Dermatologists recommends gently cleansing the blister with antimicrobial solution, taking care not to rupture it 5
  • Pierce the blister at the base with a sterile needle, with the bevel facing up, as suggested by the British Association of Dermatologists 5

When to Seek Medical Attention

  • Burns involving the face, hands, feet, and genitals require specialized care regardless of size, according to the American Heart Association 1, 6
  • Burns covering >10% body surface area should be treated in a specialized burn center, as recommended by the American College of Surgeons 3, 7

After Blister Management

  • Apply petrolatum, petrolatum-based antibiotic ointment, honey, or aloe vera and a clean nonadherent dressing to open burn wounds, as suggested by the American Heart Association 1, 2
  • The British Association of Dermatologists recommends applying a bland emollient to support barrier function and encourage re-epithelialization 5

Common Pitfalls to Avoid

  • Do not apply ice directly to burns as this can cause further tissue damage, according to the American College of Physicians 4, 6
  • Avoid using silver sulfadiazine for prolonged periods on superficial burns as it may delay healing, as recommended by the American College of Physicians 4
