Study Notes
Burn Statistics and Background
- Approximately 500,000 burn injuries requiring medical treatment annually in the U.S.
- 40,000 hospitalizations due to burns, including 30,000 patient transfers to specialized burn centers.
- 3,000-4,000 annual deaths attributed to fire and smoke inhalation.
- A civilian death from fire occurs approximately every 2 hours and 41 minutes.
- The male to female injury ratio is 2:1.
- 25% of burn injuries occur in children under 15 years old.
- Young adults aged 20-29 are 1.5 times more likely to suffer burn injuries than the broader population.
- Survival rate for burn victims has risen to ~96% due to advancements in treatment methods.
Types of Burns
- Thermal Burns: Caused by contact with hot objects, including scalding from liquids and flames.
- Electrical Burns: Result from lightning or household electrical sources, potentially damaging deep tissue.
- Chemical Burns: Result from exposure to acids or alkalis, leading to deeper tissue damage.
- Radiation Burns: Include sunburn and exposure to radiation used in medical treatments.
Initial Assessment of Burn Victims
- Airway management is critical; assess for injuries and estimate burn size.
- Evaluate depth and percentage of body surface area affected by burns.
- Check for carbon monoxide and cyanide poisoning, and assess pulses in extremities for signs of compartment syndrome.
Airway Assessment and Management
- Rapid/severe airway edema may occur due to thermal injury from smoke inhalation.
- Signs of airway injury can include perioral burns, singed nasal hairs, hoarse voice, and shortness of breath.
- Consider intubation for patients with signs of airway injury, especially with substantial facial burns.
Fluid Resuscitation
- Large bore IV access is essential; fluid volume must be managed carefully.
- Hypothermia is a common risk among burn patients; keep them warm and dry.
- Use the Parkland formula for fluid resuscitation: 4 cc/kg x % BSA in 24 hours, with half administered in the first 8 hours.
Classification of Burn Depth
- Superficial (1st degree): Affects only the epidermis; heals in 3-6 days.
- Partial Thickness (2nd degree): Involves the dermis; can be superficial or deep, takes 3-8 weeks to heal.
- Full Thickness (3rd degree): Extends into subcutaneous tissue; requires grafting and can cause severe scarring.
- Fourth Degree: Involves muscle or bone, requiring extensive surgery and presenting a life-threatening condition.
Burn Treatment and Management
- Clean wounds to provide a moist environment and prevent infection; topical agents like bacitracin and silver sulfadiazine may be used.
- Blister management is controversial; intact blisters help prevent infection, but large blisters may require debridement.
- Escharotomy: Necessary for full-thickness burns with constrictive eschar to prevent compartment syndrome.
Special Considerations for Burns
- Chemical Burns: Require thorough irrigation; damage is often deeper for alkaline burns compared to acidic burns.
- Electrical Burns: Can cause serious internal damage with minimal external signs; usually needs specialized care.
- Carbon Monoxide Poisoning: High affinity for hemoglobin leads to anoxia; treatment is high-flow oxygen, as pulse oximeters do not differentiate CO from oxygen.
Referral Guidelines to Burn Centers
- Partial-thickness burns >10% total body surface area (TBSA).
- Burns involving the face, hands, feet, genitalia, or major joints.
- Any third-degree burn regardless of size.
- Electrical, chemical, or inhalation injuries, especially in patients with complicating conditions.
Prognosis and Rehabilitation
- Key predictors for mortality include age, total body area burned, inhalation injuries, and coexisting traumas.
- Early rehabilitation is crucial to prevent functional loss, especially in hand injuries.
- Psychological therapy is important for addressing body image, PTSD, and depression.
Prevention Strategies
- Installation of fire alarms and carbon monoxide detectors to reduce injury risks.
