Clinical and laboratory studies were made to compare the water vapour permeability, bacteriological properties and clinical performance of polythene and polytetrafluoroethylene fabric (GORE-TEX) bags in the treatment of hand burns. Polythene bags are virtually impermeable to saline, whereas GORE-TEX bags containing silver sulphadiazine cream show a water vapour permeability of 0.53 ml/cm2/day, resulting in a 30 per cent weight reduction of added water after 48 h. Clinically, hand maceration and accumulation of exudate are significantly reduced in hands treated in GORE-TEX bags. The mean daily volume of accumulated exudate for GORE-TEX bags was 37 ml compared to 83 ml for polythene (P less than 0.01). When adjusted for the percentage area of the hand surface burned, this reduction remained significant (P less than 0.005). A tendency for less pain and better hand movement was noted with GORE-TEX bags. There were no significant differences in rate of healing or bacterial colonization of the burned hand between the two type of bags. GORE-TEX bags prevent skin maceration and accumulation of exudate, allowing ease of burn assessment and improved hand function. They are also durable and non-slip, thus increasing patient independence.
进行了临床和实验室研究，以比较聚乙烯袋和聚四氟乙烯织物（戈尔泰克斯）袋在手部烧伤治疗中的水蒸气渗透性、细菌学特性和临床性能。聚乙烯袋实际上对盐水是不渗透的，而含有磺胺嘧啶银乳膏的戈尔泰克斯袋的水蒸气渗透性为0.53毫升/平方厘米/天，48小时后添加的水分重量减少30%。临床上，用戈尔泰克斯袋治疗的手部浸渍和渗出物积聚明显减少。戈尔泰克斯袋渗出物的平均日积聚量为37毫升，而聚乙烯袋为83毫升（P<0.01）。根据手部烧伤面积百分比进行调整后，这种减少仍然显著（P<0.005）。使用戈尔泰克斯袋时疼痛较轻且手部活动较好。两种袋子之间烧伤手部的愈合速度或细菌定植没有显著差异。戈尔泰克斯袋可防止皮肤浸渍和渗出物积聚，便于烧伤评估并改善手部功能。它们还耐用且防滑，从而增加了患者的独立性。
