## How does Lund and Browder chart work?

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 is the palmar method?

Palmar method uses the size of the patients hand (palm and fingers) to estimate burn size. Remember to always use the patients hand, not the clinicians. In the prehospital and emergency department setting, the %TBSA burns is more important than the depth of burn.

What is burn depth?

Burn depth is classified into one of three types based on how deeply into the epidermis or dermis the injury might extend. Superficial burns (First Degree) involve only the epidermis and are warm, painful, red, soft and blanch when touched. Usually, there is no blistering. A typical example is a sunburn.

### What is the rule of nines used for?

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 nines anatomy?

What is Palmer Method in burn?

The Palmer Method of estimating total body surface area (TBSA) is an easy way to get a rough burn size estimate that can be used when calculating a patient’s fluid resuscitation needs. The patient’s palmer surface including their fingers = 1% TBSA.

#### What are the types of depth of burns?

Burns are classified as first-, second-, third-degree, or fourth-degree depending on how deeply and severely they penetrate the skin’s surface. First-degree (superficial) burns. First-degree burns affect only the outer layer of skin, the epidermis. The burn site is red, painful, dry, and with no blisters.
