rule of nines

rule

[ro̳l] a statement of conditions commonly observed in a given situation, or of a prescribed procedure to obtain a given result. For specific rules, see specific name, as m'naghten rule.rule of nines a method of estimating the extent of burns, expressed as a percentage of total body surface. In this method, the body is divided into sections of 9 per cent, or multiples of 9 per cent, each: head and neck, 9 per cent; anterior trunk, 18 per cent; posterior trunk, 18 per cent; upper limbs, 18 per cent; lower limbs, 36 per cent; genitalia and perineum, 1 per cent. The rule of nines is fairly accurate for adults but does not allow for differences in proportion in children, for whom the lund and browder classification is generally used.

Rule of nines.

rule of nines

method used in calculating body surface area involved in burns, whereby values of 9% or 18% of surface area are assigned to specific regions in the adult as follows: Head and neck, 9%; anterior thorax, 18%; posterior thorax, 18%; arms, 9% each; legs, 18% each; and perineum, 1%.

A method for rapidly assessing the extent of burns on the skin surface, which determines the amount of fluid required as replacement therapy; the head and arms each represent 9% of skin surface; anterior or posterior surface of legs represent 9% each; anterior and posterior truncal skin represent 18% each; inguinal area 1%

Critical care A method for rapidly assessing the extent of burns on the skin surface, which determines the amount of fluid required as replacement therapy; the head and arms each represent 9% of skin surface; anterior or posterior surface of legs represent 9% each; anterior and posterior truncal skin represent 18% each; inguinal area 1%

rule of nines

(rūl nīnz) Method used in calculating body surface area involved in burns whereby values of 9% or 18% of surface area are assigned to specific regions as follows: head and neck, 9%; anterior thorax, 18%; posterior thorax, 18%; arms, 9% each; legs, 18% each; perineum, 1%. Somewhat different values are used with children and infants.

RULE OF NINES

rule of nines

A formula for estimating percentage of body surface areas, particularly helpful in judging the portion of skin that has been burned. For the adult, the head represents 9%; each upper extremity 9%; the back of the trunk 18%, and the front 18%; each lower extremity 18%; and the perineum the remaining 1%.
