Study Notes

Classification of Burns

  • Burns are classified based on the depth of injury: superficial, partial-thickness, and full-thickness.
  • Critical, moderate, and minor classifications help assess burn severity.

Layers of Skin Affected

  • Superficial burns involve only the epidermis layer.
  • Partial-thickness burns affect both the epidermis and part of the dermis.
  • Full-thickness burns extend through all layers of skin, potentially damaging underlying muscles, bones, or organs.

Factors Determining Burn Severity

  • Severity is influenced by burn percentage, location on the body, patient age, and pre-existing medical conditions.

Emergency Treatment Protocol

  • Flush chemicals off the patient for 20 minutes after brushing off dry chemicals.
  • Assess airway, breathing, and mental status, then classify the burn severity.
  • Cover burn with dry, sterile dressing and keep the patient warm during transport.

Special Considerations

  • Burns to the face are categorized as critical.
  • In children, partial-thickness burns of 10-20% are classified as moderate.
  • Children under 5 and adults over 55 are less tolerant of burn injuries.

Burn Types and Indicators

  • The "Rule of Nines" is used to estimate burn area, but not for superficial burns.
  • Deep partial-thickness burns are characterized by red skin that blanches white.
  • Chemical burns require careful handling; immediate flushing with water is inappropriate for dry chemicals.

Treatment Techniques

  • Use dry, sterile dressings to separate burned fingers or toes, preventing adherence.
  • For eye burns, apply a sterile dressing to both eyes.
  • Recognize that in electrical burns, all tissues between points of entrance and exit can be affected.

Additional Information

  • Eschar is the tough tissue that forms from full-thickness burns.
  • Contact burns are caused by direct contact with hot surfaces.
