Assessing Burn Surface Area: Rule of Nines and Lund and Browder Charts Introduction to Burn Surface Area Assessment Assessing the extent of burns is crucial for determining severity, guiding treatment decisions, and predicting outcomes. Two commonly used methods for estimating burn surface area are the Rule of Nines and Lund and Browder charts. Rule of Nines The Rule of Nines provides a quick estimation of total body surface area (TBSA) affected by burns, using multiples of nine for different body regions: • Adults: Each major body region represents approximately 9% or multiples of 9% of TBSA. Head and Neck: 9% Each Arm: 9% (total for both arms) Anterior Trunk: 18% Posterior Trunk: 18% Each Leg: 18% (total for both legs) Genitalia: 1% Children: The percentages vary slightly with age, where each limb segment may be proportionally smaller compared to adults. o o o o o o • Lund and Browder Charts The Lund and Browder chart provides a more precise assessment by dividing the body into smaller areas, each assigned a specific percentage of TBSA: • • • Advantages: Takes into account variations in body proportions and provides a more accurate assessment for individuals with different body sizes and shapes. Method: The chart divides the body into segments, with different percentages allocated depending on the age of the patient and the specific area affected by burns. Usage: Healthcare professionals use these charts to document and monitor burn injuries, aiding in treatment decisions, fluid resuscitation calculations, and predicting healing times. Clinical Application and Benefits 1. Accurate Assessment: Allows for a more precise calculation of burn severity and TBSA involvement. 2. Treatment Guidance: Helps determine the need for referral to burn centers based on the percentage of TBSA affected and the depth of burns. 3. Fluid Resuscitation: Guides initial fluid resuscitation calculations, essential for managing burns to prevent shock and optimize patient outcomes. 4. Long-Term Monitoring: Useful for documenting burn healing progress and planning for reconstructive surgery or rehabilitation. Challenges and Considerations 1. Age and Body Proportions: Adjustments are necessary for infants, children, and individuals with atypical body shapes. 2. Depth of Burns: Lund and Browder charts do not assess burn depth (superficial, partial-thickness, full-thickness), which influences treatment and prognosis. 3. Secondary Assessments: Additional clinical evaluations, such as assessing inhalation injury or other associated trauma, are crucial for comprehensive management. Conclusion The Rule of Nines and Lund and Browder charts are essential tools in assessing burn surface area, aiding healthcare providers in triaging and managing patients with burn injuries effectively. Understanding these methods ensures accurate estimation of TBSA involvement, facilitates appropriate treatment decisions, and supports optimal outcomes for patients affected by burns. Regular updates and training in burn assessment techniques are crucial for healthcare professionals to maintain proficiency and ensure consistent quality care in burn management
