Total Body Surface Area(TBSA) Total body surface area (TBSA) is an assessment measure of burns of the skin, burned surface area is calculated as a percentage of total body surface area to determine burn size. In adults, the rule of nines is used to To approximate the percentage of burned surface area. 燒燙傷總表面積(TBSA of burn, total body surface area) 一般而言,燒燙傷的嚴重程度,是以受損皮膚的「深度」與「面積」所佔身體表面積的百分比來評估, 醫護人員通常採用「Wallace九則計算法」計算病患燒燙傷面積大小。 「Wallace九則計算法」是先將身體表面積劃分為一百個等分,再依身體各部位所佔身體表面積劃分為數個9% (本計算方式適用於成人,兒童比例略有不同,且傷口深度必須傷及表皮與真皮乳頭層以下,才列入計算。) 頭、頸9%
