All chronic wounds are colonized by bacteria. Increased bacterial burden or critical colonization can be deleterious to wound healing. In view of the ubiquitous presence of microbes, the clinician must discern whether bacterial balance (contamination or colonization) or bacterial damage has occurred. Silver is a common topical agent used to combat bacterial burden in chronic wounds. Given the wide array of silver-related wound care products, it is difficult to determine which product should be used. By reviewing relevant scientific evidence, we propose an acronym SILVER to address the key contentious issues. These issues are summarized as SILVER: Signs of bacterial damage, the need for Ionic silver, Log reduction of bacteria, Vehicle (importance of moisture balance), Effect on normal cells, and Bacterial Resistance.
所有慢性伤口都有细菌定植。细菌负荷增加或严重定植会对伤口愈合产生有害影响。鉴于微生物无处不在,临床医生必须辨别是否发生了细菌平衡(污染或定植)或细菌损伤。银是一种常见的局部用药,用于对抗慢性伤口中的细菌负荷。鉴于与银相关的伤口护理产品种类繁多,很难确定应使用哪种产品。通过回顾相关科学证据,我们提出了首字母缩写词SILVER来解决关键的争议问题。这些问题总结为SILVER:细菌损伤迹象、离子银的需求、细菌对数减少、载体(水分平衡的重要性)、对正常细胞的影响以及细菌耐药性。
