Palmer Method

mage of palm to represent using the palm of burn victim to estimate total body surface area.

Palm of patient is approximately 1% of surface area

Estimate with fingers positioned together as above. Utilize the patients palm size not your own.

The palmer method of estimating total body surface area (TBSA) is an easy way to get a rough burn size estimate that can be used when calculating a patients fluid resuscitation needs.

The patient’s palmar surface including their fingers = 1% TBSA
