The significance of even pressure application and protection against shearing forces using a tie-over dressing of skin grafts has been stressed previously. Several methods for pressure enhancement have been described with no quantification or comparison between the different techniques. Rubber foam and metal staples are commonly used for simple and quick application of the dressings. We developed a model for analyzing the contact interface of the dressing with the skin graft and the pressure exerted by it. A stapled rubber foam tie-over dressing was compared with the original silk thread tie-over dressing. Six different embodiments were also analyzed, all constructed using only rubber foam and metal staples. Imprint and maximal projection analyses of the undersurfaces were performed. The original silk thread tie-over dressing exerted a relatively low pressure but was uniformly distributed. A regular stapled tie-over dressing applied a ring-shaped pressure with minimal projection. Other methods are described providing different contact areas with the grafts and different pressures.
先前已强调了使用植皮区包扎敷料均匀施加压力及防止剪切力的重要性。已经描述了几种增强压力的方法，但未对不同技术进行量化或比较。橡胶泡沫和金属吻合钉通常用于简单快速地应用敷料。我们开发了一个模型，用于分析敷料与植皮区的接触界面及其施加的压力。将吻合钉固定的橡胶泡沫包扎敷料与原始丝线包扎敷料进行了比较。还分析了六个不同的实施方案，所有方案均仅使用橡胶泡沫和金属吻合钉构建。对底面进行了压痕和最大投影分析。原始丝线包扎敷料施加的压力相对较低，但分布均匀。常规的吻合钉固定包扎敷料施加环形压力，投影最小。还描述了其他方法，这些方法提供了与植皮区不同的接触面积和不同的压力。
