When calculating burns using the palm method, what does 1% represent?

The palm method for calculating burn size is based on the surface area of the patient's own hand, where approximately the entire palm and fingers together represent about 1% of the total body surface area (TBSA). This method is practical and quick, allowing healthcare providers to estimate the extent of burns by using the patient's hand as a reference point.

For instance, if a burn covers an area equivalent to one full palm of the patient, it can be determined that the burn area is roughly 1% of the individual's total body surface area. This is crucial in assessing the severity of burns, guiding treatment, and determining the need for trauma care or fluid resuscitation based on the total burn extent. Utilizing the patient's hand ensures that the measurement accurately reflects the individual's body size and proportion, which is essential given the variations in body size among patients.
