What percentage of total body surface area (TBSA) defines a major burn classification for adults?

The classification of a major burn in adults is defined by the percentage of total body surface area (TBSA) affected by burns. According to established medical guidelines, a burn that covers 20% or more of the TBSA in adults is categorized as a major burn. This classification is crucial as it helps determine the management and treatment protocols, including the need for fluid resuscitation, potential hospitalization in a burn unit, and surgical interventions.

The threshold of 20% signifies a significant level of injury that can lead to serious complications, including shock and infection, thus requiring a higher level of medical attention. Understanding the percentage classification ensures that healthcare providers can effectively assess the severity of burns and allocate appropriate resources.

In comparison, lower percentages like 10%, 15%, and 25% do not define the threshold for major burns according to the commonly accepted standards used in clinical settings. While 25% might indicate a more severe injury requiring serious consideration, it is the 20% mark that officially classifies a burn as major in adults.
