摘要 [目的]观察单体纳米银溶液(Nano silver)对大鼠压疮的治疗效果。[方法]15只Wistar大鼠在胫骨隆突内侧建立Ⅱ期压疮模型,共30处创面。将符合纳入标准的20处压疮创面随机分为:对照组(n=10)和观察组(n=10)。对照组采用传统外科换药治疗,观察组将创面直接暴露于330mg/L浓度的单体纳米银溶液中,评价两组的创面愈合率及组织学定量评价分数。[结果]对照组大鼠存活4只,死亡1只,压疮创面标本8处;观察组大鼠全部存活,创面标本10处;创面愈合率和组织学定量评价两组比较差异有统计学意义(P<0.05),观察组好于对照组。[结论]相比传统治疗,压疮创面直接暴露于单体纳米银溶液治疗方案可更快促进创面的愈合,有效防治大鼠压疮继续发展。
