Infrared thermography is a useful technique for the investigation of disorders which affect skin blood flow. The damage to skin blood vessels caused by thermal injury is a major determinant of the capacity of the wound to heal. Thermographic assessment of this damage has been found to correlate with the healing time of burn wounds. However, the application of thermography to the assessment of burns for early surgery has been limited because of the difficulties involved in correcting for cooling artefacts resulting from the effect of evaporative water loss (EWL) at the wound surface. A water impermeable polyvinylchloride film (sold in the USA as Saran Wrap, in Australia as Glad Wrap and in the UK as Clingfilm (CF)) was investigated as a wound covering to avoid this cooling effect. It was found that the CF abolished the cooling effect of EWL and did not significantly interfere with the measurement of surface temperature. This material provides a solution to the problems of thermographic examination of wounds such as burns where damage to the skin surface allows exudation or EWL to occur.
红外热成像技术是一种用于研究影响皮肤血流紊乱的有用技术。热损伤对皮肤血管造成的损害是伤口愈合能力的主要决定因素。已发现对这种损害的热成像评估与烧伤创面的愈合时间相关。然而,由于难以校正伤口表面蒸发失水(EWL)效应导致的冷却伪影,热成像在早期手术烧伤评估中的应用受到限制。研究了一种不透水的聚氯乙烯薄膜(在美国作为莎伦包装膜出售,在澳大利亚作为格拉德包装膜出售,在英国作为保鲜膜(CF)出售)作为伤口覆盖物以避免这种冷却效应。发现CF消除了EWL的冷却效应,并且没有显著干扰表面温度的测量。这种材料为诸如烧伤等伤口的热成像检查问题提供了解决方案,在这些伤口中,皮肤表面受损会导致渗出或EWL发生。
