Total body surface area (TBSA) is a measurement used to estimate the percentage of a person's body that has been burned. It is a crucial factor in determining the severity of a burn injury and guiding treatment decisions.
- TBSA is calculated as a percentage of the total body surface. This measurement helps healthcare providers assess the extent of the burn and determine the appropriate course of treatment.
- The TBSA calculation is essential for fluid resuscitation. For burns greater than 20% TBSA, intravenous (IV) fluids are typically administered to prevent dehydration and maintain adequate blood pressure.
- Several methods can be used to estimate TBSA, including the "Rule of Nines" for adults, the Lund and Browder chart for children, and the Palmar Method, which uses the patient's palm as a reference point.
The Palmar Method is a simple way to estimate TBSA. It involves comparing the size of the burn to the patient's palm, assuming that the palmar surface represents approximately 1% of the total body surface area.
Understanding the TBSA percentage is critical in managing burn injuries. It helps healthcare professionals determine the severity of the burn, guide treatment decisions, and estimate the patient's prognosis.
