The size of a burn can be quickly estimated by using the “rule of nines.” This method divides the body’s surface area into percentages. 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.
What is the rule of 9’s burn chart?
For adults, a “Rule of Nines” chart is widely used to determine the percentage of total body surface area (TBSA) that has been burnt (10,15,16). The chart divides the body into sections that represent 9 percent of the body surface area. It is inaccurate for children, and should be used in adults only.
What is the importance of the rule of nines?
Why Is the Rule of Nines Helpful? The rule of nines gives an idea of how much of your total body’s surface area a burn takes up . This informs treatments based on the size and intensity of the burn injury. Emergency medical responders are some of the medical workers who use the rule of nines most.

What is the medical definition of rule of nines?
The Rule of Nines, also known as the Wallace Rule of Nines, is a tool used by trauma and emergency medicine providers to assess the total body surface area (TBSA) involved in burn patients.
How can you tell what degree a burn is?
- First-degree burns affect only the outer layer of the skin. They cause pain, redness, and swelling.
- Second-degree burns affect both the outer and underlying layer of skin. They cause pain, redness, swelling, and blistering. ...

Can you survive burns to 90% of your body?

Can you survive 85% burns?
In one retrospective review of 238 severely burned patients, the survival rate for patients with >95 percent total body surface area (TBSA) burns was approximately 50 percent for children aged 14 years and younger, 75 percent in adults 45 to 64 years , and 30 percent in older patients [116].
Can you survive 50% burns?
Most people can survive a second-degree burn affecting 70 percent of their body area, but few can survive a third-degree burn affecting 50 percent. If the area is down to 20 percent, most people can be saved, though elderly people and infants may fail to survive a 15 percent skin loss.
How do you use the rule of nines?
To apply the rule of nines, add up all the areas of the body that are burned deep enough to cause blisters or worse (2 nd or 3rd-degree burns). For example, the entire left arm and the chest covered in blisters would be 18 percent.
How is Tbsa determined?
To calculate the %TBSA (quotient), it is necessary to divide the burned surface area (Burned BSA) (numerator in cm2) by the total body surface area (Total BSA) (denominator in cm2). By using everyday objects (eg.
How are burns calculated for kids?
The size of a burn for a baby or young child can be quickly estimated by using the “rule of nines .” This method divides a baby’s body surface area into percentages. The front and back of the head and neck are 21% of the body’s surface area. The front and back of each arm and hand are 10% of the body’s surface area.
