Treatment of Burns Present for 20 Hours

Burn Assessment and Classification

  • The American Heart Association recommends determining burn depth and total body surface area (TBSA) to guide treatment decisions 1, 4
  • Superficial (first-degree) burns involve only the epidermis and generally heal without scarring 1
  • Partial-thickness (second-degree) burns involve the epidermis and part of the dermis 1
  • Full-thickness (third-degree) burns involve destruction of the epidermis and injury to deeper layers 1

Treatment Algorithm Based on Burn Severity

For Minor Burns (Can Be Managed at Home):

  • Clean the burn area gently 1
  • Apply petrolatum, petrolatum-based antibiotic ointment, honey, or aloe vera to small partial-thickness burns 2, 3
  • Cover with a clean nonadherent dressing 2, 3
  • Administer over-the-counter pain medications such as acetaminophen or NSAIDs 2, 3
  • Remove any jewelry from the affected area to prevent constriction as swelling occurs 2, 3

For Severe Burns (Require Medical Attention):

  • Burns requiring specialized care include:
    • Burns involving the face, hands, feet, or genitalia 1
    • Full-thickness burns of any size 4
    • Partial-thickness burns >10% TBSA in adults or >5% in children 4
    • Burns with signs of inhalation injury (facial burns, difficulty breathing, singed nasal hairs, soot around nose/mouth) 1

Topical Treatment Options

  • For burns being managed at home, apply petrolatum, petrolatum-based antibiotic ointment, honey, or aloe vera 2, 3

Pain Management

  • Administer over-the-counter analgesics such as acetaminophen or NSAIDs 2, 3
  • These medications are well-tolerated and effective for burn pain 2, 3

Monitoring for Complications

  • Monitor for adequate urine output (0.5-1 mL/kg/hr) in more severe burns 4
  • Assess pain control regularly 4

Special Considerations

  • At 20 hours post-burn, the initial inflammatory response has already occurred, so fluid resuscitation formulas are no longer applicable unless there are signs of dehydration 5

When to Seek Emergency Care

  • If there are signs of inhalation injury (facial burns, difficulty breathing, singed nasal hairs, soot around nose/mouth) 1, 4
  • If the burn involves >10% TBSA in adults or >5% in children 1, 4
  • If the burn involves the face, hands, feet, or genitalia 1, 4
