Why is accurate TBSA determination crucial in burn management?
Why is accurate TBSA determination crucial in burn management?
Accurate TBSA assessment is essential for calculating appropriate fluid resuscitation volumes. Both underestimation and overestimation can have detrimental effects, leading to shock or fluid overload, respectively.
A patient presents with scattered burns on their arms and legs. Which TBSA assessment method is most practical in the initial prehospital setting?
A patient presents with scattered burns on their arms and legs. Which TBSA assessment method is most practical in the initial prehospital setting?
The rule of palm is best suited for this situation.
A burn patient is estimated to have 18% TBSA burns. Would they typically receive immediate fluid resuscitation based on general guidelines?

No, fluid resuscitation is typically initiated for adult patients with burns covering 20% or more of their TBSA.

Study Notes
Total Body Surface Area (TBSA) in Burns
- TBSA is crucial in guiding burn treatment, especially fluid resuscitation.
- Incorrect estimations (under or over) can negatively affect patient outcomes.
- Underestimation leads to inadequate resuscitation and potential shock/organ failure.
- Overestimation risks complications such as pulmonary edema.
- Adults require resuscitation at 20% or more TBSA.
Methods for Determining TBSA
-
Rule of Palm: A patient's hand (including fingers) is approximately 1% of TBSA.
- Useful in prehospital settings for burns of various sizes, scattered burns, and mass casualty situations.
-
Rule of Nines: The most common prehospital method for TBSA estimation.
- Divides adult body surface into 9% segments or multiples.
- Modifications are needed for infants and children due to differing body proportions.
- A significant limitation is that it assumes uniform body proportions among all adults, irrespective of their specific body shapes and sizes.
