Study Notes
Burn Injury Overview
- Burns result from the transfer of energy from a heat source to the body, leading to the destruction of the integumentary system.
- Major causes of burn injuries in the USA include carelessness with cigarettes and hot water heaters.
- In Pakistan, common causes include misuse of gasoline heaters, cooking accidents, and suicidal attacks.
Types of Burn Injury
-
Thermal Burns:
- Most prevalent type, accounting for 2/3 of burn cases.
- Caused by flames, hot surfaces, hot liquids, sunburn, hot metals, etc.
-
Chemical Burns:
- Result from exposure to strong acids or alkalis.
- Require immediate and specialized care to prevent further skin injury.
-
Electrical Burns:
- Caused by electrical sources, often difficult to assess externally.
- Medical evaluation is crucial even if the burn appears minor.
-
Inhalation (Smoke) Injury:
- Damage caused by inhalation of smoke and toxic fumes, requiring immediate medical attention.
-
Radiation Burns:
- Result from exposure to radiation sources, potentially causing deep tissue injury.
-
Cold Thermal Injury (Frostbite):
- Occurs when skin and underlying tissues freeze, leading to tissue damage.
Management Strategies
- Timely and appropriate treatment is critical for all burn types.
- Special considerations for chemical burns include neutralizing agents to halt skin damage.
- Electrical burns necessitate thorough evaluation due to hidden injuries beyond visible symptoms.
