Rapid estimation of acute hand burns is important for communication, standardisation of assessment, rehabilitation and research. Use of an individual's own thumbprint area as a fraction of their total hand surface area was evaluated to assess potential utility in hand burn evaluation.
Ten health professionals used an ink-covered dominant thumb pulp to cover the surfaces of their own non-dominant hand using the contralateral thumb. Thumbprints were assessed on the web spaces, sides of digits and dorsum and palm beyond the distal wrist crease. Hand surface area was estimated using the Banerjee and Sen method, and thumbprint ellipse area calculated to assess correlation.
Mean estimated total hand surface area was 390.0cm±SD 51.5 (328.3-469.0), mean thumbprint ellipse area was 5.5cm±SD 1.3 (3.7-8.4), and mean estimated print number was 73.5±SD 11.0 (range 53.1-87.8, 95% CI 6.8). The mean observed number of thumbprints on one hand was 80.1±SD 5.9 (range 70.0-88.0, 95% CI 3.7), χ=0.009. The combined mean of digital prints was 42, comprising a mean of two prints each on volar, dorsal, radial and ulnar digit surfaces, except volar middle and ring (3 prints each). Palmar prints were 15 (11-19), dorsal 15 (11-19), ulnar palm border 3, first web space 2, and second, third and fourth web spaces one each. Using the surface of the palm alone, excluding digits, as 0.5% of total body surface area, the area of one thumbprint was approximated as 1/30th of 1%.
We have demonstrated how thumbprint area serves as a simple method for evaluating hand burn surface area.
快速评估急性手部烧伤对于沟通、评估标准化、康复和研究都很重要。本研究评估了使用个体自身拇指印面积占其全手表面积的比例，以评估其在手部烧伤评估中的潜在效用。
十名健康专业人员用蘸有墨水的优势拇指指腹，通过对侧拇指覆盖其非优势手的表面。在指蹼间隙、手指侧面、远端腕横纹以外的手背和手掌上评估拇指印。使用Banerjee和Sen方法估计手表面积，并计算拇指印椭圆面积以评估相关性。
估计的平均全手表面积为390.0cm±标准差51.5（328.3 - 469.0），平均拇指印椭圆面积为5.5cm±标准差1.3（3.7 - 8.4），平均估计的拇指印数量为73.5±标准差11.0（范围53.1 - 87.8，95%可信区间6.8）。一只手上观察到的拇指印平均数量为80.1±标准差5.9（范围70.0 - 88.0，95%可信区间3.7），χ = 0.009。数字印的合并平均值为42，其中手掌、手背、桡侧和尺侧手指表面平均各有两个印，除手掌中、环指（各有3个印）。手掌印为15个（11 - 19），手背印为15个（11 - 19），尺侧手掌边缘印为3个，第一指蹼间隙印为2个，第二、第三和第四指蹼间隙印各为1个。仅将不包括手指的手掌表面作为全身表面积的0.5%，一个拇指印的面积约为1%的1/30。
我们已经证明了拇指印面积是评估手部烧伤表面积的一种简单方法。
