摘　　要：目的探讨伤口红光照射时不同敷料对红光透射率的影响.方法模拟伤口红光照射治疗环境,分别检测并比较临床常用四大类19种敷料的红光透射率,透射率为透过伤口敷料的红光辐照强度与入射红光的辐照强度的比值.结果各敷料的红光透射率分别为:(1)纱布棉垫类:一块粗纱布29.4%,一片棉垫10.5%;(2)油纱类:浅色的油纱敷料73.0%~79.1%,深色油纱敷料-德湿银41.7%;(3)水胶体类:水胶体敷料87.8%~90.2%;(4)泡沫类:浅色超薄泡沫-美皮康超薄型74.7%,黑色厚泡沫-美皮康银0.8%,其他泡沫敷料20.5%~54.2%.结论水胶体敷料、浅色油纱敷料、浅色超薄泡沫敷料的红光透射率较高,影响较小,而深色敷料和较厚的敷料影响较大.纱布、棉垫对于红光透射率影响很大,纱布块及棉垫不适宜用于红光治疗时伤口临时覆盖.在伤口接受红光照射治疗时,需要考虑到伤口敷料对红光透射率的影响.Objective To investigate the influence of different types of wound dressings on red light transmittance.Methods A treatment environment for wounds exposed to red light was simulated.Red light transmittance of four types of 19 dressings commonly used in clinic were detected respectively and compared.The transmittance was calculated as the ratio of the intensity of the red light through the dressing to the intensity of the injected red light.Results The red light transmittance for each dressing was the following:(1)Cotton gauze and pad:29.4%for one piece of coarse gauze,10.5%for one cotton pad;(2)Oil dressings:73.0%-79.1%for light-color oil dressings,41.7%for dark-color oil dressings-Atrauman^(■);(3)Hydrocolloid dressings:87.8%〜90.2%;(4)Foams:74.7%for light-color ultra-thin foam-Mepilex^(■)sheet,0.8%for black-color thicker foam dressings-Mepilex^(■)Ag dressing,and 20.5%-54.2%for the other foam dressings.Conclusions The red light transmittance of hydrocolloid dressing,light-colored oil gauze dressing and light-colored ultra-thin foam dressing is higher,with less red light-blocking effect,and the dark-color or thicker dressings had more blocking effect,which showed different therapeutic effect on wound.Gauze and cotton pad have great blocking influence on red light transmittance,and are not suitable for temporary covering of wound during red light treatment.Hence,the effect of wound dressing on red light transmittance should be taken into account when the wound is treated with red light.
