Rule of Palm Palmar method o It can be used in Children as well as in adults. o It is used for small burns o The palm of patients hand represents I of BSA. Palm is the area of hand from wrist crease to the finger crease. o Entire burned hand represents 2.5 of BSA: 1 for palm; 1 for dors um of the hand excluding fingers;0. 5 for the fingers.
