Explanation · 中文詳解

九分法(Rule of Nines)成人燒傷面積估算:頭頸部 9%、軀幹前部(胸+腹)18%、軀幹後部 18%、每隻手臂 9%、每隻腿(前+後)18%、會陰 1%。本題「胸+腹+雙腿」= 18%(前軀幹)+ 18%×2(雙腿)= 54%,故正解為 B。其他選項:A 18% 只計算前軀幹;D 36% 只計算雙腿;C 45% 為錯誤加總。

Using the Rule of Nines, the anterior trunk (chest and abdomen) accounts for 18% of the total body surface area, and each leg accounts for 18%. Therefore, burns involving the anterior trunk and both legs result in a total estimated burn area of 54% (18% + 18% + 18%).

✦ 台美臨床差異

美台皆採九分法,但在緊急燒傷評估上,美國護理單位對液體復甦公式(Parkland formula)的執行流程更為嚴格。
