伤口大小的测量可以预测愈合并提供指导治疗的信息。本研究评估了一种新的光学伤口成像系统，创建一个三维图像的ulcus.Using一个新的基于摄像头的数字系统和传统的椭圆形伤口测量，36足部溃疡31例患者（年龄44-94岁，中位数70岁）在12周期间在两个中心进行了检查。糖尿病中位病程为18年（范围6-56年）。17%患有1型糖尿病，93%患有周围神经病变，57%患有外周动脉疾病。连续审查了25例，共进行了76次溃疡检查。中位溃疡尺寸为94 mm（2），尺寸范围为3.1至2195 mm（2）。Pearson、斯皮尔曼和Kendall等级系数显示数字测量伤口与传统手工测量估计值之间存在强相关性（所有病例P < 0.001）。使用数字椭圆测量（DEM）得出的伤口长度的观察者内变异系数<3.0%。使用DEM的伤口长度的观察者间变异<6.5%。在30次试验中，与标准已知大小伤口面积的差异< 8.0%。这项研究表明，数字和传统测量技术之间存在很强的相关性。该系统可以很容易地部署在常规临床实践中，提供客观的视觉记录，允许远程深入分析。糖尿病。Med.26，93-96（2009）。
Measurement of wound size can predict healing and provide information to guide treatment. This study assesses a novel optical wound imaging system that creates a three-dimensional image of the ulcer.Using a new camera-based digital system and traditional elliptical wound measurements, 36 foot ulcers from 31 patients (aged 44-94 years, median 70 years) were examined during a 12-week period at two centres. Median diabetes duration was 18 years (range 6-56 years). Seventeen percent had Type 1 diabetes, 93% had peripheral neuropathy and 57% had peripheral artery disease. Twenty-five were reviewed consecutively, resulting in 76 ulcer examinations. Median ulcer size was 94 mm(2), with size ranging from 3.1 to 2195 mm(2).Pearson, Spearman and Kendall rank coefficients showed a strong correlation (in all cases P < 0.001) between digital measurements of wounds against traditional hand-measured estimates. Intra-observer variation of wound length using digital elliptical measurement (DEM) gave a coefficient of variation of < 3.0%. Interobserver variation of wound length using DEM was < 6.5%. Variation from a standard known-size wound area was < 8.0% across 30 trials.This study shows a strong correlation between digital and traditional measurement techniques. The system can be easily deployed in routine clinical practice, providing an objective visual record, allowing remote in-depth analysis.Diabet. Med. 26, 93-96 (2009).
