Two types of dressing, occlusive and exposure dressing, are commonly used in burn units. A dressing is said to be occlusive if a moist wound surface is maintained when the dressing is in place. This study was designed to compare the effectiveness of occlusive and exposure dressing in controlling burn infections.
Two hundred patients with second-degree burns admitted to Mottahari Hospital, Tehran, Iran, over a period of 12 months from May 2012 to May 2013 were studied. They were divided into two groups of 100 each, to receive either occlusive or exposure dressing. During the first week of treatment, wound specimens were obtained by sterile swab and cultured in selective media. Demographics (age and gender), burn areas, cause of burn, length of hospital stay (LOS), type of infections and time to total healing were compared between the two groups.
Occlusive dressing was more susceptible to microbial contamination and infections than exposure dressing. The mean duration of treatment based on epithelialization and healing in occlusive dressing was longer than for exposure dressing. The most common isolate was Pseudomonas spp., followed by Enterobacter, Escherichia coli, Staphylococcus aureus, Acinetobacter, and Klebsiella spp.
Exposure dressing was more suitable than occlusive dressing for treating partial-thickness at our center. Pseudomonas aeruginosa was the most common organism encountered in burn infection.
烧伤病房常用两种敷料，即封闭性敷料和暴露性敷料。如果敷料在位时能保持创面湿润，则称该敷料为封闭性敷料。本研究旨在比较封闭性敷料和暴露性敷料在控制烧伤感染方面的效果。
对2012年5月至2013年5月期间入住伊朗德黑兰莫塔哈里医院的200例二度烧伤患者进行了为期12个月的研究。他们被分为两组，每组100例，分别接受封闭性敷料或暴露性敷料治疗。在治疗的第一周，通过无菌拭子获取创面标本，并在选择性培养基中培养。比较两组患者的人口统计学特征（年龄和性别）、烧伤面积、烧伤原因、住院时间、感染类型和完全愈合时间。
与暴露性敷料相比，封闭性敷料更容易受到微生物污染和感染。基于上皮化和愈合的封闭性敷料平均治疗时间比暴露性敷料长。最常见的分离菌是假单胞菌属，其次是肠杆菌属、大肠埃希菌、金黄色葡萄球菌、不动杆菌属和克雷伯菌属。
在我们中心，暴露性敷料比封闭性敷料更适合治疗浅二度烧伤。铜绿假单胞菌是烧伤感染中最常见的病原体。
