使用患者自己的手作为工具来估计烧伤面积已有充分记录。据估计，一只手的手掌表面面积占身体表面积的 1%。测量手的手掌表面面积以测试该估计的准确性，然后与常用公式计算的体表面积进行比较。这项研究还试图确定手部生长的自然历史，以便开发出一种随时可用的床边方法来估计手部面积和体表面积。从 800 名年龄从 2 岁到 89 岁不等的志愿者中获得了双边手部痕迹。使用积分面积计确定每条描迹的面积。测量了每个人的身高和体重。并计算他/她的体表面积。通过计算手面积除以体表面积的商来确定手掌手的体表面积百分比。此外，手的宽度是从小指掌指折痕处的尺侧到拇指靠在食指根部的点测量的。手的长度是从茎突中部到中指尖的距离。将这两个数字相乘即可得到近似手部面积的乘积。根据最常用的计算体表面积的杜波依斯公式，手的手掌表面面积相当于成人体表面积的 0.78 +/- 0.08%。该百分比随年龄的不同而有所不同，在幼儿中最高可达 0.87 +/- 0.06%。将手的长度乘以手的宽度只会高估由面积测量法确定的手的面积，仅高估了 2%。患者自己的手可以用作补充的、容易获得的模板来估计烧伤区域或其他疾病或损伤区域。在成人中，手部轮廓的描画面积占体表面积的 0.78%，而在儿童中，这个数字往往略高。在急诊室或给病房加油时，长度乘以手的宽度的简单乘积将非常接近面积测量法确定的面积。该方法可以比 1% 的估计更准确地确定手部手掌表面的面积，这可能会导致对成人烧伤伤口大小的高估。
The use of a patient's own hand as a tool to estimate the area of burn injury is well documented. The area of the palmar surface of one hand has been estimated to be 1 percent of the body surface al ea. The area of the palmar surface of the hand was measured to test the accuracy of this estimate and then compared with the body surface area as calculated by formulas in common use. This study also sought to determine the natural history of the growth of the hand to permit development of a readily available, bedside means of estimating hand area and body surface ar ea. Bilateral hand tracings were obtained from 800 volunteers ranging in age from 2 to 89 years. The area of each tracing was determined using an integrating planimeter. The height and weight of each individual were measured. and his/her body surface area was calculated. The palmar hand's percentage of body surface area was determined by calculating the quotient for hand area divided by body surface area. Additionally, the width of the hand was measured from the ulnar aspect at the palmar digital crease of the small finger to the point where the thumb rested against the base of the index finger. The length of the hand was measured from the middle of the interstylon to the tip of the middle finger. These two figures were multiplied together to obtain a product which approximated the area of the hand. Based on the most commonly used DuBois formula for calculating body surface area, the area of palmar surface of the hand corresponds to 0.78 +/- 0.08 percent of the body surface area in adults. The percentage varies somewhat with age and reaches a maximum of 0.87 +/- 0.06 percent in young children. Multiplying the length of the hand by its: width overestimates the area of the hand as determined by planimetry by only 2 percent. A patient's own hand may be used as a complementary, readily available template for estimation of burn area or other areas of disease or injury. In adults, the area of tracing of the outline of the hand is 0.78 percent of the body surface area, whereas in children, this number tends to be slightly higher. In the emergency room or oil the wards, a simple product of length multiplied by width of the hand will closely approximate the areas as determined by planimetry. This method allows a more accurate determination of the area of the palmar surface of the hand than the 1 percent estimate, which may lead to an overestimation of the size of a burn wound in adults.
