Treatment of Minor Burns

Classification of Burns

  1. First Degree-Also known as superficial burns. They only involve the epidermis with swelling, redness, and pain. Blanches with pressure. Doesn't blister and heals quickly without scarring. Healing time is 3-6 days. Ex: Sunburns
  2. Second Degree –Also known as partial-thickness burns. They involve the entire epidermis and portions of the dermis. They are characterized as either superficial or deep.
    1. Superficial Partial-Thickness Burns: Forms blisters within 24 hours. Painful, red, and blanch upon pressure. Painful to temperature and air. Healing takes 7 to 21 days. Scarring is unusual.
    2. Deep Partial-Thickness Burns: These damage hair follicles and glandular tissue. Painful to pressure only. Always blisters and easily unroofed. They do not blanch with pressure. Healing takes more than 21 days to heal and they tend to cause hypertrophic scarring. A deep partial thickness burn that fails to heal in 21 days is functionally and cosmetically similar to a third degree burn.
  3. Third Degree- Also known as full thickness burns. These affect the entire epidermis and dermis. The nerves endings are destroyed and so usually there is no pain. The skin is dry and inelastic and does not blanch with pressure. Color can vary from waxy-white to black. Because of the inability to epithelialize, grafting is necessary.
  4. Fourth Degree- potentially life threatening burn that extends into the underlying tissue such as fascia, muscle, and/or bone.

Minor burns: Partial thickness burn that are <10 % of the total surface body area (TSBA) in patients between 10-50 years old,  or <5% of TSBA in patients <10 yrs or >50 yrs old, or a full thickness burn that is <2% of TSBA in any patient without other injuries. These are generally treated as outpatient.

First Aid for Burns

  1. Cleaning: Should just use mild soap and tap water as skin disinfectants can inhibit the healing process.  
  2. Cooling as soon as possible. This can limit the inflammation and thermal damage. Best to use cool water or ice pack wrap. Ice application has been associated with frostbite and should be avoided. 
  3. Pain Control- Acetaminophen usually helpful but may need to use opiates such as codeine. 
  4. Check immunization status and update tetanus if necessary.
  5. Debridement of Bulla- there are some differences of opinion regarding breaking of blisters.
    1. Some suggest leaving intact because the blister acts as a barrier to infection and others debride all blisters. 
    2. Most agree that after blister ruptures necrotic skin should be removed.
  6. Application of Antibiotics- suggest use of ointments. Should always be used to prevent infection in any non-superficial burns.
    1. Mucopiricin- good Streptococcal and Staphylococcal coverage.
    2. Neosporin/ Bacitracin
    3. Silvadene- has good gram negative coverage and gram negative infections predominate in the second week after the burn. Disadvantage is because it is difficult to see the burn under the Silvadene. 
  7. Dressing- should use a non-adherent dressing and is usually applied after the application of antibiotic ointments.
    1. Superficial burns do not require dressing.
    2. Basic dressing includes a first layer of non-adherent gauze (ex. adaptic) then a second layer of fluffed dry gauze, and an outer layer of elastic gauze (ex. Kerlix)
    3. May want to inspect the wound frequently but not necessarily take off the entire dressing. Can inspect for warmth, redness, and drainage without removing all the layers.
    4. Dressing should be changed when they are soaked.
  8. Pruritus- Itching is a common problem in the healing process and systemic antihistamines are often used (ex. diphenhydramine)
  9. Follow up- Look for signs of infection, scarring, and contracture. There should be a follow up visit the day after injury to adjust pain medications, assess dressing change competence, and possibly to debride the wound. Thereafter, follow up visit can be done on a weekly basis or until epithelialization is complete.
    1. When to refer: Patients with minor burns should be referred to a surgeon with expertise in burn care if epithelialization has not begun after two weeks or if further evaluations shows full-thickness burn greater than 2 cm. Referral should also occur if there are such wound complications as infection or the development of necrotic tissue.
