What is the total percentage of TBSA for the entire torso in adults according to the Rule of Nines?

The total percentage of Total Body Surface Area (TBSA) for the entire torso in adults, according to the Rule of Nines, is considered to be 36%. This calculation divides the body into regions, assigning a specific percentage to different areas for quick assessment of burn injuries. In adults, the torso comprises two main components: the anterior trunk and the posterior trunk, each accounting for 18% of TBSA. When combined, these areas sum up to 36%, which makes it crucial for accurate calculations in managing burn injuries and guiding treatment decisions. Understanding this percentage is essential for healthcare professionals to determine fluid resuscitation needs and overall burn severity evaluations.
