Study Notes
Definition
- Coagulative necrosis is the primary form of tissue necrosis, resulting in cellular swelling, breakdown of organelles, and denaturation of cytoplasmic proteins.
Causes
- Thermal injuries: can be wet (scalds) or dry (flame)
- Chemical burns: involve acids or alkalis
- Cold injuries: frostbite
- Irradiation: damage from radiation exposure
- Electrical injuries: from high-voltage sources
Pathophysiology
- Loss of epithelial cover leads to increased susceptibility to infections.
- Fluid loss can cause shock and renal failure.
- Underlying structures (blood vessels, nerves, muscles, and bone) may sustain damage.
Classification
- Depth classification includes partial thickness (superficial and deep) and full thickness burns.
- Percentage of body surface area affected is assessed using:
- Wallace’s Rule of Nines
- Lund and Browder chart
- Palm Rule for adults
Management
- Initial assessment includes history (burn time, contact time, location) and first aid.
- Examination indicators of severity include facial burns, sooty cough, nasal hair singeing, total body surface area (TBSA), and burn depth.
Resuscitation
- Fluid resuscitation calculated with formulas like Parkland (4 x TBSA x weight).
- Continuous monitoring of urinary output, blood pressure, temperature, and pulse is essential.
- Investigative tests include full blood count (FBC), urea, electrolytes, and microbiological cultures.
Admission Criteria
- Preferably to a burn unit for specialized care.
- Burns to special areas including face, hands, feet, and perineum warrant admission.
- For adults, full thickness burns (FTB) > 10% and partial thickness burns (PTB) > 15%; for children, FTB > 5% and PTB > 7.5% require specialized care.
- Chemical and electrical burns necessitate immediate admission.
Treatment
- Intravenous fluids such as Ringer's lactate are commonly administered.
- Antibiotics are prescribed to prevent or treat infection.
- Analgesia for pain management.
- Vitamins to support healing processes.
- Dressings to protect wounds from infection and trauma.
- Nutritional support to assist recovery.
- Physiotherapy to promote mobility and function.
Complications
- Potential complications include infection, contractures, psychological impacts, disfigurement, scarring, and in severe cases, death.
