How Can Inspiratory Capacity Help Manage My Lung Disease? Let's be honest - sometimes the best body surface area calculator is the one that is easy to use and doesn't require us to even know what the body surface area formula is in the first place! Based on the rule of nines calculation, each part of the body makes up a certain percentage of the total body surface area. Measuring the size of a burn is difficult because every person is different in size, shape, and weight. For example, the area of the head makes up a relatively large portion of the total skin area in infants as compared with adults. Since its first publication in 1944, this formula has established accuracy. Calculating the body's total surface area of a large burn is important because it helps doctors determine a burn's severity. The total body surface area (TBSA) of a burn can be calculated with a Lund and Browder Chart, Wallace Rule-of-Nines or the palmar method. Before taking the quiz, don’t forget to watch the lecture on the Parkland Burn Formula. Kamolz L, Lumenta D, Parvizi D, et al. 1. Lund and Browder chart, on average, provides a 3% more accurate calculation of total body surface area burnt with less variability that using Wallace’s Rule of Nines4. Added all together, these sections account for 99 percent. Download this PDF of the Lund and Browder Chart here. What Happens When You Wear Shoes That Don't Fit? Since the sum of all triangles equals 100%, the marked area as percentage of total body surface area is from a mathematical point of view absolutely provable, which was the ratio for its use in the first place. Its limitation is in relation to clinical inefficiency. It is called the rule of nines because each part is either 9% or a factor of 9. In an adult who has been burned, the percent of the body involved can be calculated as follows: If both legs (18% x 2 = 36%), the groin (1%) and the front chest and abdomen were burned, this would involve 55% of the body. The Lund-and-Browder Chart, Wallace Rule-of-Nines and the palmar method are different ways to calculate and estimate the total body surface area (TBSA) of a burn. To simplify calculations, the palmar method is often described as representing 1% of the patients totally body surface area. For children and infants, the Lund and Browder chart is used to assess the burned body surface area. It is commonly used in healthcare practice because of its clinical efficiency and proven accuracy6,7. For adults, doctors often use the rule of nines. Calculate Your Family's Health Insurance Penalty. The genitals make up the last one percent of the total body surface area.

These are: an age of more than 60 years, burn size of more than 40 percent of body-surface area, and inhalation injury. Courtesy of the American Burn Association. To calculate with the Parkland Formula, you must know how to calculate total burn surface area using the Rule of Nines. These 3 calculations have an established role in the primary assessment of burns. Initial Burns Fluid Calculator. side 2 is the surface of one of the sides, and since the cube has 6 equal sides, multiplying by 6 gives us the total cube surface area. See a picture of the "rule of nines" for adults. There is no exact percentage that can predict mortality of burns. 309 x 400 png 57kB. The main benefit of using the Wallace Rule of nines is the clinical efficiency. To approximate the percentage of burned surface area, the body has been divided into eleven sections: Each of these sections takes about nine percent of the body's skin to cover it. These estimations are heavily user dependent which may result in over-estimation and significant inter-rater variability2. Therefore, a correct evaluation of these factors is optimal for adapting the appropriate treatment in modern burn care. Lund C, Browder NC. Use the person's palm to measure the body surface area burned. 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). There is a concern among clinicians of the accuracy of the Rule of Nines pertaining to the obese and pediatric populations. The Rule of Nines is calculated by assigning percentages to different areas of the body. The Rule of Nines can often over-estimate the total body surface area percentage of a burn4. Overall, burn severity is a measurement of the depth of burning and the size of the burn. The Rule of Nines can be used as an alternative to the Lund and Browder Chart for calculating the total body surface area (TBSA) involved in burn patients. Tennison in 1947 and later published by Wallace in 19515. TBSA is calculated using the Lund-Browder Classification Method. NICE guidelines for Burns and Scalds recommend the palm including digits in the estimation of smaller or scattered burns. The determination of total burn surface area: how much difference? Burn depth and burn size are crucial determinants for assessing patients suffering from burns . The Lund and Browder chart takes these factors into consideration for full thickness and partial thickness burns. The formula states that the fluid requirements (FR) are equal to total body surface burned (%) * weight (kg) * 4 mL. It is for full-thickness and partial thickness burns. Family Uninsured? You can estimate the body surface area on an adult that has been burned by using multiples of 9. Total Body Surface Area TBSA burns You can quickly estimate the total body surface area of a burn by using the "rule of nines" in adults.In babies and young children, different percentages are used because the ratio of the combined surface area of the head and neck to the surface area of the limbs is typically larger in children than that of an adult(See table below). Additionally, Lund-Browder specifies six age groups (to account for changes in body makeup as individuals develop into adulthood). Body Surface Area Calculator. Estimating burn size in adults. National Burn Repository 2005: a ten-year review. Limitations are noted in the paediatric and obese population.
