Study Notes
Burn Injury Incidence
- Flame and scald burns are the most common types, with home accidents accounting for 73% of cases.
- Scald injuries are most common in children under 5.
- Approximately 486,000 people with burn injuries receive treatment each year, with over 3,000 deaths annually, many due to residential fires.
- Males constitute 68% of burn victims.
- Burns are a leading cause of death in all age groups, particularly affecting children under 14 and older adults.
- Risk factors in older adults include reduced mobility, sensory decline, cognitive impairment and chronic illnesses.
- Mortality is high in older adults (>60 years), patients with more than 40% TBSA burns, and those with inhalation injuries (nearly 90%).
- Prevention methods include smoke detectors, fire extinguishers, and fire safety campaigns.
- Preventing scalds involves water temperature regulation in bathrooms with anti-scald technology.
Burn Depth Classification
- Burn damage is categorized by tissue depth.
- Burns are categorized as superficial, superficial partial-thickness, deep partial-thickness, or full-thickness.
- Superficial burns affect only the epidermis (outer skin layer), causing redness and pain like a sunburn, usually healing in 7 days without scarring.
- Superficial partial-thickness burns involve the epidermis and part of the dermis, causing blistering, redness, and moist exposed skin; these heal in 2 weeks.
- Deep partial-thickness burns extend deeper into the dermis, causing pain, dry or moist, mottled red/white skin, and potentially longer healing times with scarring.
- Full-thickness burns penetrate through the dermis into the subcutaneous tissue, or even deeper muscle or bone, leading to a painless, dry, white or blackened appearance, and require grafting or other advanced treatment.
Burn Shock
- Burn shock occurs in patients with burns greater than 20% of total body surface area (TBSA).
- Shock develops due to fluid loss from the bloodstream into damaged tissues (capillary leak) in combination with the systemic response (distributive shock).
- Early signs include tachycardia, hypotension, decreased urine output.
- Significant loss of fluid, protein, and electrolytes can lead to systemic issues.
- Monitoring of vital signs, and fluids is required, along with frequent assessments for proper fluid resuscitation.
Burn Care Phases
- Burn care is divided into three phases: emergent/resuscitative, acute/intermediate, and rehabilitation.
- Emergent phase prioritizes immediate first aid, preventing shock and respiratory distress, and assessing the extent and depth of injuries.
- The acute/intermediate phase focuses on wound care, preventing complications, and providing nutritional support.
- The rehabilitation phase aims at wound closure, scar management, and restoring functionality and well-being to the patient.
