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.
What is the formula for calculating burn?
For example, a person weighing 75 kg with burns to 20% of his or her body surface area would require 4 x 75 x 20 = 6,000 mL of fluid replacement within 24 hours. The first half of this amount is delivered within 8 hours from the burn incident, and the remaining fluid is delivered in the next 16 hours.
What is TBSA 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 patients fluid resuscitation needs. The patient’s palmar surface including their fingers = 1% TBSA. Courtesy of the American Burn Association.
Are first degree burns included in TBSA?
The extent of the burn injury is expressed as a percentage of the patient’s total body surface area (TBSA). Superficial (first-degree) burns are not included in percentage TBSA burn assessment . This estimation can be facilitated using a Lund-Browder chart, the Rule of Nines, or the palm method.
How do you calculate body surface area for a burn?
- 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.
How are burns classified?
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.
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 formula for calculating Evans?
Parkland formula practice questions for burns for the NCLEX exam. ... To calculate with the Parkland Formula, you must know how to calculate total burn surface area using the Rule of Nines . Before taking the quiz, don’t forget to watch the lecture on the Parkland Burn Formula.
What is parkland Baxter formula?
The widely quoted Baxter (Parkland) formula for initial fluid resuscitation
What fluid is used for burns?
| Formula Fluid in First 24 Hours | Parkland RL at 4 mL/kg per percentage burn | Evans NS at 1 mL/kg per percentage burn, 2000 mL D5W*, and colloid at 1 mL/kg per percentage burn | Slater RL at 2 L/24 h plus fresh frozen plasma at 75 mL/kg/24 h |

What are the 6 C’s of Burn Care?
Burns are now commonly classified as superficial, superficial partial thickness, deep partial thickness and full thickness. A systematic approach to burn care focuses on the six “Cs”: clothing, cooling, cleaning, chemoprophylaxis, covering and comforting (i.e., pain relief).
How do you assess a burn patient?
During a burn evaluation, your health care provider will carefully look at the wound. He or she will also figure out an estimated percentage of total body surface area (TBSA) that has been burned. Your provider may use a method known as the “ rule of nines ” to get this estimate.
How do you assess the severity of a burn?
Burn Severity. Severity of burn injury is determined by the depth of injury, extent of body surface injured , location of burn on the body, age of the patient, pre-burn medical history and circumstances or complicating factors (e.g., smoke inhalation, other traumatic injuries).
What are the 3 types of burn?
- First-degree burns are mild (like most sunburns). The top layer of skin (epidermis) turns red and is painful but doesn’t typically blister.
- Second-degree burns affect skin’s top and lower layers (dermis). ...
- Third-degree burns affect all three skin layers: epidermis, dermis and fat.
What are the 6 types of burns?
- Thermal burns. Burns due to external heat sources that raise the temperature of the skin and tissues. ...
- Radiation burns. Burns caused by prolonged exposure to ultraviolet rays of the sun. ...
- Chemical burns. ...
- Electrical burns. ...
- Friction burns.
What is 1st 2nd and 3rd degree burns?
Second-degree burns ( partial thickness burns ) affect the epidermis and the dermis (lower layer of skin). They cause pain, redness, swelling, and blistering. Third-degree burns (full thickness burns) go through the dermis and affect deeper tissues. They result in white or blackened, charred skin that may be numb.
