一位病患胸部、腹部及雙腿燒傷。使用九分法估計,燒傷體表面積約為多少?
A client is admitted with burns on the chest, abdomen, and both legs. Using the Rule of Nines, what is the estimated body surface area (BSA) burned?

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。
