What is the Rule of Nines?

The Rule of Nines is a clinical tool used by medical professionals to estimate the Total Body Surface Area (TBSA) affected by a burn. It divides the body into sections of 9% (or multiples of 9) to allow for quick assessment in emergency situations.

How does the Rule of Nines differ for children?

In infants and young children, the head occupies a larger percentage of TBSA (18%) while the legs occupy less (14% each). This calculator automatically adjusts the percentages when the 'Pediatric' mode is selected.

Why is TBSA calculation important?

Calculating TBSA is critical for determining the severity of a burn and guiding fluid resuscitation needs (using formulas like the Parkland Formula) and deciding if a patient needs a specialized burn center.

Verbrand Lichaamsoppervlak (Regel van Negen)

Bereken het totale lichaamsoppervlak (TBSA) dat door brandwonden is aangetast. Ondersteunt volwassen en pediatrische patiënten.

In the emergency management of burn victims, the most critical initial calculation is the Total Body Surface Area (TBSA) affected. This percentage determines everything from the volume of IV fluids required for resuscitation (the Parkland Formula) to whether a patient meets the criteria for transfer to a specialized Burn Center. The Rule of Nines is a rapid, reliable method for estimating this area by dividing the body into sections that represent approximately 9% of the total surface. Our calculator provides a visual interface to select these areas and automatically adjusts the percentages for pediatric patients, whose body proportions differ from adults.

Klinische Tip

Bij de Regel van Negen worden eerstegraads brandwonden (zoals zonnebrand) meestal niet meegeteld voor de vochttoediening. Focus op 2e en 3e graads gebieden.

Hoe het werkt

The tool uses the Wallace Rule of Nines for adults and the modified Lund-Browder proportions for pediatric patients. It sums the percentages of all selected body parts to provide a total TBSA estimate.

Waarom zou u deze tool in uw dagelijks leven gebruiken?

Precisie bij trauma. Deze dienst vervangt mentale benaderingen door een gestandaardiseerde, op bewijs gebaseerde berekening, waardoor slachtoffers van brandwonden de agressieve vloeistoftherapie krijgen die nodig is om hypovolemische shock te voorkomen.
