  1. 2.1.3. How to calculate burn area?
    • 2010/10/15 17:28:55
    The general method is: using the percent of burn surface area. In the total 100% body surface area, head and neck occupy 9%(head, face and neck occupies 3% separately); both upper extremities occupy 18%(both upper arms occupy 7%, both forearms occupy 6%, both hands 5%); body including perineum occupy 27% (fore body occupies 13%, back body occupies 13% and perineum 1%); both lower extremities (including buttocks) occupy 46% (both buttocks 5%, both thighs 21%, both legs 13%, both feet 7%)(for female, both feet and buttocks occupy 6%).
     
    There is one more simple method: the area of the patients palm occupies 1% of body surface area.
     
    In clinic, the second degree burn with TBSA=10% or below for adults is called mild burn; 11-30% or third degree burn with TBSA=10% or below is called moderate burn; 31-50% or third degree burn with TBSA=11-20% is called severe burn. For patients mentioned above, if accompanied with shock, midrange inhalation damage or other injury, the severity increases one grade. If the TBSA is larger than 50% or third degree burn with TBSA larger than 20%, its called extraordinary severe burn.
