Extent of burn injury
Miller-Keane Encyclopedia and Dictionary of Medicine, Nursing,
and Allied Health, Seventh Edition. (2003).
Rule of Nines
The total body surface is divided into areas of
9%. The perineum accounts for 1% in adults.
The extent of burn can be described as
percentage total body surface area (TBSA).
It is relatively accurate in adults, but inaccurate
in children without modification because
children have proportionally smaller hips and
legs and larger shoulders and heads than
adults.
