Use of the patient's hand to estimate percentage body surface area (BSA) of injury is well established in the management of burns. Exactly what constitutes "the palm of the hand' and how large an area this is, depends on whether you follow Advanced Trauma Life Support teaching. United Kingdom teaching, or use a "Lund and Browder chart'. A study was designed to measure the areas in question to find which was most accurate. The conclusions challenge standard teaching and show a sex difference. The area of the palm alone is 0.5 per cent BSA in males and 0.4 per cent BSA in females, whereas the area of the palm plus the palmar surface of the five digits is 0.8 per cent BSA in males and 0.7 per cent BSA in females. Therefore if a hand alone is used to assess the size of a burn the per cent BSA could be overestimated.
在烧伤治疗中，使用患者的手来估算烧伤的体表面积（BSA）百分比是一种公认的方法。究竟什么构成“手掌”以及其面积有多大，这取决于你遵循的是高级创伤生命支持教学、英国的教学方法，还是使用“伦德与布劳德图表”。一项研究旨在测量相关面积，以找出哪种方法最准确。研究结论对标准教学提出了挑战，并显示出性别差异。仅手掌的面积在男性中占体表面积的0.5%，在女性中占0.4%，而手掌加上五指掌面的面积在男性中占体表面积的0.8%，在女性中占0.7%。因此，如果仅用手来评估烧伤面积，体表面积百分比可能会被高估。
