The pediatric "Rule of Nines" is a tool used by medical professionals to quickly estimate the Total Body Surface Area (TBSA) affected by second- or third-degree burns. Because children have proportionally larger heads and smaller legs than adults, the percentages differ.
What is the rule of 9's for children?
The pediatric "Rule of Nines" estimates the percentage of Total Body Surface Area (TBSA) burned. Because children have proportionally larger heads and smaller legs than adults, the percentages differ. For infants under 1 year, the head is 18% and each leg is 14%. For ages 1–9, adjustments are made yearly as they grow.
What is the rule of 9 for adults?
The front and back of the head and neck equal 9% of the body's surface area. The front and back of each arm and hand equal 9% of the body's surface area. The chest equals 9% and the stomach equals 9% of the body's surface area. The upper back equals 9% and the lower back equals 9% of the body's surface area.
Why is it called the rule of 9?
Each part of the body is broken up into increments of 9%, hence the rule of nines. For example, each adult arm counts as 4.5% for the front and 4.5% for the back, accounting for 9% for each arm out of a total of 100% of the entire body.
What is the rule of 9 for babies?
The infant Rule of Nines is a clinical tool used to quickly estimate the Total Body Surface Area (TBSA) affected by second- or third-degree burns. Because infants have proportionally larger heads and smaller legs than adults, the percentages are adjusted to ensure accurate fluid resuscitation calculations.
Rule of Nines (9's) for Children
What is the 3 6 9 rule for kids?
under 3 years of age: no screen media. under 6 years of age: no own gaming console. under 9 years of age: no own mobile phone or smartphone. under 12 years of age: no unsupervised computer use/social media use.
How to calculate rule of 9?
The "Rule of Nines" is a medical tool used by first responders and doctors to quickly estimate the Total Body Surface Area (TBSA) affected by burns. It works by dividing the adult body into anatomical sections that are represented by 9% or multiples of 9%.
Is the rule of 9 for adults only?
The rule of nines was designed for adult patients. It is less accurate in young children due to their proportionally bigger heads and smaller mass in the legs and thighs, although one study did find it was accurate for patients as small as 10 kg.
Who invented the rule of nine?
In 1951, Alexander Burns Wallace published his Rule of Nines, which is a simpler method that assigns a defined percentage to each part of the human body, regardless of weight and body shape (e.g., android, gynecoid, mixed) (5).
Has anyone survived 90% burns?
At just 9 years old, John O'Leary suffered severe burns over 90% of his body in a 1987 accident. Doctors gave him a 1% chance of survival. Now, O'Leary's story is the focus of "Soul on Fire" — a new film set to premiere in theaters nationwide on Friday.
Who created the rule of 9?
The Rule of Nines was first discussed by Pulaski and Tennison in 1949 and later presented at the National Burns Research Council at a symposium; in 1951, A.B. Wallace published an article in the Lancet in describing the Rule of Nines.
What is the rule of nine test?
The "Rule of Nines" most commonly refers to the widely used emergency medical assessment for estimating the Total Body Surface Area (TBSA) of partial- and full-thickness burns in adults.
What is the most common burn in children?
Toddlers and children are more often burned by a scalding or flames. Most children ages 4 and under who are hospitalized for burn-related injuries suffer from scald burn (65%) or contact burns (20%). Hot tap water burns cause more deaths and hospitalizations than burns from any other hot liquids.
When applying the rule of nines to a 10 month old child?
Correct. For infants, the head accounts for a greater proportion of total body surface area (TBSA) compared to adults. According to the pediatric rule of nines (more specifically, the Lund and Browder chart), the head is assigned 18% of TBSA in infants.
What is the rule of 9?
The Rule of Nines is a quick, practical tool used by emergency medical providers and doctors to estimate the Total Body Surface Area (TBSA) affected by second- and third-degree burns. It divides an adult's body into sections that represent approximately 9% (or multiples of 9%) of the total skin area.
What is the rule of 9 in math?
The rule of 9s (divisibility rule) states that a number is divisible by 9 if the sum of its digits is divisible by 9. To apply it, sum all digits, and if the total is divisible by 9, the original number is too. This process can be repeated. For example, 162: 1+6+2=9, so 162 is divisible by 9.
Why is the rule of 9 important?
The Rule of Nines is a tool which can assist healthcare providers to understand what percentage of a burn patient's total body surface area (TBSA) is affected by second- and third-degree burns. The article includes details on how to use the tool and considerations for treating obese or pediatric patients.
Why is it called the rule of nines?
The Anatomy Behind the Rule: Why the Number Nine? Each “nine” reflects a standardized ninth of the whole body surface. The origin of this division lies in early 20th-century dermatology and surgical teaching, where linear anatomical proportions aligned with glycerin or tape measurements across body segments.
Does the rule of nines apply to children?
Doctors don't typically use the same calculations in the rule of nines to children. This is because children tend to have different body proportions than adults do, including larger heads and smaller legs.
What is the age for adults only?

The best first aid for burns is cool running water. Hold the burned area under cool, running water as soon as possible for 20 minutes. Always supervise children in the kitchen and keep hot drinks and food out of reach.
What does TBSA stand for?
TBSA stands for Total Body Surface Area, a medical measurement representing the percentage of a person’s body surface that has been burned, commonly used for assessing injury severity and calculating fluid resuscitation needs. It is essential for guiding treatment strategies in acute burn management.
What does 3% burn mean?
A third-degree burn destroys your first three layers of skin and fatty tissue. A third-degree burn may not immediately hurt, but you'll notice your skin is charred-black, dry and leathery. This type of burn is serious and requires treatment by a healthcare provider.
What is the rule of 9 burns for infants?
The pediatric Rule of Nines estimates the Total Body Surface Area (TBSA) of partial or full-thickness burns. Infants have proportionally larger heads and smaller legs than adults, so the percentages differ.
