摘要: 为了确定不同的含银医用敷料在银的释放量和释放速度上的区别,分析了几种含银医用敷料释放银离子的性能。介绍了测试抗菌性能的3种方法,并总结了含银医用敷料的抗菌性能及临床疗效。结果显示,不同的伤口对银离子的释放量有不同的要求。烧伤病人的伤口特别容易受感染,因此在烧伤伤口上使用的含银医用敷料的银离子释放量高,在伤口上可以维持较高浓度的银。在高吸湿性的医用敷料中,细菌和伤口渗出液一起被吸进敷料,从敷料上释放出少量的银离子即可达到抗菌的目的。

Abstract: In order to determine the amount and speed of silver ion release from different silver-contained wound dressings,this paper analyzed the silver release properties of several silver-contained dressings.Three antimicrobial test methods were described and the antimicrobial performances of various silver products were summarized.Results showed that different types of wounds require different amounts of silver ions.Burn wounds are easy to be infected,so they require a large amount of silver from the dressing in order to maintain a higher silver concentration on the wound.With highly absorbent wound dressings,bacteria and exudates are absorbed into the dressing at the same time,thus only a small amount of silver released from the dressing would be effective in achieving antimicrobial effect.
