TBSA stands for Total Body Surface Area of the burn. It is usually preceded by a percentage that indicates the size of the total body surface area. For example, 10% TBSA. Burns are generally categorized into four stages: mild burns, moderate burns, severe burns, and extra severe burns. 1. Mild burns are second-degree burns with less than 10% of the total surface area. The burns are generally less severe and recovery is faster after injury. 2. Moderate burns are second-degree burns with a total area of between 11% and 30%, which usually injure the entire epidermis and usually heal in 1-2 weeks in the absence of infection. 3. Severe burns are third-degree burns with a total area of 31%-50%, usually destroying the epidermis and dermis, and are more serious. 4. Extra-severe burns refer to burns with a total area of 50% or more of the III degree burns, this time the patient is more serious, the patient can not heal themselves, treatment attention depends on surgical implants, and sometimes even life-threatening. In the case of burns, mild burns can be dealt with in the outpatient clinic, more than moderate burns recommend that patients go to the regular hospital as soon as possible, for further treatment, so as not to delay the condition.
