Body surface area. In physiology and medicine, the body surface area (BSA) is the measured or calculated surface area of a human body. For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass. Nevertheless, there have been several important critiques of the use ...
14%. The Wallace rule of nines is a tool used in pre-hospital and emergency medicine to estimate the total body surface area (BSA) affected by a burn. In addition to determining burn severity, the measurement of burn surface area is important for estimating patients' fluid requirements and determining hospital admission criteria.
Total body surface area. Total body surface area (TBSA) is an assessment of injury to or disease of the skin, such as burns or psoriasis. In adults, the Wallace rule of nines can be used to determine the total percentage of area burned for each major section of the body. [1]
The Lund and Browder chart is a tool useful in the management of burns for estimating the total body surface area affected. It was created by Dr. Charles Lund, Senior Surgeon at Boston City Hospital, and Dr. Newton Browder, based on their experiences in treating over 300 burn victims injured at the Cocoanut Grove fire in Boston in 1942.
The cardiac index (CI) is a hemodynamic measure that represents the cardiac output (CO) of an individual divided by their body surface area (BSA), expressed in liters per minute per square meter (L/min/m²). This parameter provides a more accurate assessment of heart function relative to the size of the individual, as opposed to absolute ...
The Parkland formula is mathematically expressed as: [4] where mass (m) is in kilograms (kg), area (A) as a percentage of total body surface area, and volume (V) is in milliliters (mL). 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.
To allow comparison of results between people of different sizes, the C Cr is often corrected for the body surface area (BSA) and expressed compared to the average sized man as mL/min/1.73 m 2. While most adults have a BSA that approaches 1.7 m 2 (1.6 m 2 to 1.9 m 2), extremely obese or slim patients should have their C Cr corrected for their ...
The BSA is usually calculated with a mathematical formula or a nomogram, using the recipient's weight and height, rather than by direct measurement of body area. This formula was originally derived in a 1916 study and attempted to translate medicinal doses established with laboratory animals to equivalent doses for humans. [ 16 ]
