The Rule of Nines is a method healthcare professionals use to estimate the total body surface area (TBSA) affected by burns. This tool aids in assessing the severity of burn injuries, guiding fluid resuscitation, and determining patient transfer needs. Each body part is assigned a percentage, divided into increments, for example, 9%, for the front and back of the head (4.5% each) or legs (9% each). For pediatric patients, the percentages are adjusted due to different body proportions. Accurate TBSA calculation helps ensure proper treatment and avoid complications from incorrect fluid dosing. The Rule of Nines is crucial in treating serious burns, such as second and third-degree burns.

Mrs. Cohen explains this in detail and goes over a few sample questions on the video below.
