Burns | Dermatology # 9 | First Aid USMLE in Urdu/Hindi
Understanding burns classification, mortality causes, and critical fluid resuscitation formulas like Parkland is key for effective management.
Watch on YouTube ↗Key takeaways
- 🎯Burn mortality follows a timeline: asphyxia/neurogenic shock (immediate), hypovolemia (1-3 days), and septic shock (beyond 3 days).00:34
- 🚀Memorize the timeline of burn mortality to anticipate potential complications.00:34
- 💡Burns are classified by depth: First-degree (epidermis), Second-degree (dermis, superficial or deep), Third-degree (full thickness, to fat), and Fourth-degree (to muscle/fascia).03:10
- 🔍Distinguishing second-degree burns relies on blisters and blanching: superficial partial thickness burns have blisters and blanching, while deep partial thickness burns may lack blanching and be less painful.07:07
- 📈The Rule of Nines (or Wallace Rule) is a common method to estimate the Total Body Surface Area (TBSA) affected by burns, assigning specific percentages to different body regions.11:11
- 🎯Apply the Rule of Nines to quickly estimate the TBSA percentage in burn patients.11:11

The digest
This educational session provides a detailed explanation of burns, focusing on their definition, types, causes of mortality, classification by depth, estimation of total body surface area (TBSA) affected, and management protocols, especially fluid resuscitation. Intended for medical students preparing for USMLE or similar exams, the lecture uses clear clinical examples and practical frameworks, emphasizing critical concepts relevant to burn assessment and first aid.
Understanding Burns and Causes of Mortality
Burns are injuries caused by heat exposure (fire, flames), damaging skin tissues and sometimes deeper structures. A clinical scenario illustrates three patients caught in a fire: one dying on the spot, two admitted to a hospital, with one dying within 1 to 3 days.
- On-spot deaths mainly result from:
- Asphyxia (airway obstruction or respiratory failure due to smoke inhalation)
- Neurogenic shock (loss of autonomic nervous system control causing circulatory collapse)
- Early deaths (within 1-3 days post-admission) mainly occur due to:
- Hypovolemic shock from massive fluid loss caused by vascular permeability and plasma leakage
- Late deaths are primarily caused by:
- Septic shock, frequently induced by infections from Pseudomonas aeruginosa and other bacteria due to compromised skin barrier
