1. What is the Palm Method?

The palm method is a quick way to estimate the percentage of total body surface area (TBSA) burned in emergency situations. The patient's palm (including fingers) represents approximately 1% of their TBSA.

2. How Does the Calculator Work?

The calculator uses the simple palm method formula:

Where:

• 1 palm = approximately 1% of TBSA
• Includes fingers and palm area

Explanation: This method provides a rapid estimate of burn extent by counting how many palm-sized areas are burned.

3. Importance of Burn Percentage Estimation

Details: Accurate burn size estimation is crucial for determining fluid resuscitation needs, triage decisions, and prognosis. Burns >20% TBSA in adults often require specialized burn care.

4. Using the Calculator

Tips: Count the number of palm-sized burn areas (can use partial palms for smaller burns). Enter the total number of palms (can use decimals for partial palms).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the palm method?
A: It provides a quick estimate (±5% accuracy) and is most useful in pre-hospital settings. More precise methods (Lund-Browder chart) should be used in hospital.

Q2: Does this work for children?
A: The palm method can be used, but note that children have different body proportions (larger head, smaller legs relative to adults).

Q3: What about very large burns?
A: For extensive burns, you can subtract unburned areas from 100% (e.g., if half the body is unburned, then ~50% is burned).

Q4: How does this compare to the "Rule of Nines"?
A: The Rule of Nines gives quick estimates for large areas (e.g., entire arm = 9%), while the palm method is better for scattered or irregular burns.

Q5: When should I seek medical attention for burns?
A: Seek immediate care for burns >10% TBSA, burns on face/hands/feet/genitals, or any full-thickness (white/charred) burns.
