Thermal burn is a type of burn resulted from making contact with heated objects, such as boiling water, steam, hot cooking oil, fire, and hot objects. Scalds are the most common type of thermal burn suffered by children, but for adults thermal burn is most commonly caused by fire. Burn are generally classified from first degree up to fourth degree, but the American Burn Association (ABA) has categorized thermal burns as minor, moderate, and major, based almost solely on the depth and size of the burn. ==Pathophysiology== There are three (or sometimes four) degrees of burns, in ascending order of severity and depth. For more info, see Burn#Signs and symptoms. According to Jackson's thermal wound theory, there are three zones of major burn injury, shaped usually like a bull's-eye. *Zone of coagulation at the center of the wound, where all tissue is damaged. *Zone of stasis surrounds the coagulation area, where some tissue is undamaged. *Zone of hyperemia is the unburned area surrounding zone of stasis, but it is red due to increased blood flow through inflammatory response.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thermal burn」の詳細全文を読む スポンサード リンク
