说明：本研究的目的是描述选定的骶骨组织的特点，在一个方便的样本健康志愿者subjects.DESIGN：Descriptional.SAMPLE AND SETTING：50名健康志愿者在临床学习中心在学校nursing.METHODS：骶骨扫描获得使用20 MHz的超声扫描系统在3个位置：俯卧位和60和90侧躺从后面。图像由超声程序中的软件使用真皮厚度和密度的定量参数进行分析结果：一般来说，平均值如下：真皮厚度在2.32和2.65 mm之间;中值像素强度在102和112之间; LEP：TP比值在0.39和0.56之间。受试者侧卧位（60和90）与俯卧位的骶骨组织特征在厚度和真皮密度（中位数强度和LEP：TP比值）测量值之间存在显著差异，所有P值均小于。0001.结论：总体而言，除了侧卧位和俯卧位之间的系统性差异外，厚度和真皮密度测量值的范围是一致的。当比较厚度、中值强度或LEP：TP比率时，报告受试者位置很重要。为了在表面变化之前最好地识别指示压力损伤的组织炎症，了解健康的高频超声骶骨组织特征是有用的。预计定量评估皮肤厚度，密度和LEP：TP的比例可以帮助识别个人与早期的压力损伤。
OBJECTIVES:The purpose of this study was to describe selected sacral tissue characteristics in a convenience sample of healthy volunteer subjects.DESIGN:Descriptive.SAMPLE AND SETTING:Fifty healthy volunteers in a clinical learning center in a school of nursing.METHODS:Sacral scans were obtained using a 20-MHz ultrasound scanning system in 3 positions: prone and 60 and 90 side-lying from the back. The images were analyzed by software in the ultrasound program using quantitative parameters of dermal thickness and density (dermal median intensity and derived number of low-echogenic pixels to total pixels [LEP: TP] ratio).RESULTS:In general, average values were as follows: dermal thickness between 2.32 and 2.65 mm; median pixel intensity between 102 and 112; and the LEP: TP ratio between 0.39 and 0.56. There were significant differences in sacral tissue characteristics between measures of thickness and dermal density (median intensity and LEP: TP ratio) by subject side-lying position (60 and 90) versus prone position, with all P values less than. 0001.CONCLUSIONS:Overall, the ranges were consistent across measures of thickness and dermal density except for systematic differences between side-lying and prone positions. When comparing thickness, median intensity, or LEP: TP ratio, it is important to report subject position. To best recognize tissue inflammation indicative of pressure injuries before surface changes are seen, it is useful to understand healthy high-frequency ultrasound sacral tissue characteristics. It is anticipated that quantitative assessment of dermal thickness, density, and LEP: TP ratio could help identify individuals with incipient pressure injury.
