What do the rule of nines and Lund and Browder charts assess?
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. An accurate estimation of a burn guides acute management, fluid resuscitation, nutrition supplementation and prognosis.
Why is the Lund and Browder chart more accurate?
Lund and Browder chart—This chart, if used correctly, is the most accurate method. It compensates for the variation in body shape with age and therefore can give an accurate assessment of burns area in children. It is important that all of the burn is exposed and assessed.
What is the Lund and Browder chart used for?
For children and infants, the Lund-Browder chart is commonly used to assess the burned body surface area. Different percentages are used in paediatrics because the surface area of the head and neck relative to the surface area of the limbs is typically larger in children than adults.
What are the three common methods burn size estimation determine how they are used?
Determining burn percentage was done by one the 3 common methods of Lund-Browder, rule of nines and patient’s palm.
What is Lund and Browder formula?
For children and infants, the Lund-Browder chart is used to assess the burned body surface area. 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.
What does the Lund Browder method estimate?
a method for estimating the extent of burns that allows for the varying proportion of body surface in persons of different ages. It is used instead of the rule of nines for children, in whom the head occupies a larger area and the lower limbs a smaller area than in adults.
What is Lund Browder method?
What is Parkland formula used for?
The Parkland formula is used to calculate fluid resuscitation for critical burn patients.
Why is Parkland Formula important?
Maintain circulatory volume in the face of losses due to the burn – this is essential for cardiac output, renal perfusion and tissue perfusion; Provide metabolic water; Maintain tissue perfusion to the zone of stasis and prevent the burn from deepening.
How does the rule of nines work?
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.
Which is more accurate, Lund Browder or rule of nines?
Several studies have compared the various methods of estimating burn surface. The Lund Browder charts are more accurate than either the Rule of Nines or palm size in identifying TBSA. The Rule of Nines is faster and more convenient to use for adult burn patients in emergency situations, however, it is not accurate for children or for obese people.
What is the Lund and Browder burn chart?
What is the Lund and Browder Chart? The Lund and Browder (LB) chart, which was developed in 1944 3, is the most broadly used tool worldwide to calculate the total body surface area of a burn. Lund and Browder chart is the most accurate graphical record of the extent of the burn 4.
What is the Wallace rule of nines for Burns?
Wallace rule of nines—This is a good, quick way of estimating medium to large burns in adults. The body is divided into areas of 9%, and the total burn area can be calculated. It is not accurate in children. Lund and Browder chart—This chart, if used correctly, is the most accurate method.
When was the rule of nines invented for burn patients?
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. It was first described by E.J. Palaski and C.W. Tennison in 1947 and later published by Wallace in 1951 5.
