In order for silver to be biocidal it must be in an ionic form. The higher the ionic state (the more electrons missing) the greater the ability of the ionic silver to interfere or react with the normal function of a microorganisms cell. Most silver dressings generally contain singly ionic silver (Ag1+), making them effective for the management of infected wounds. This article presents the results of a service evaluation in which a new patented silver wound dressing (KerraContact Ag) that uses silver in its most active state (Ag3+) to facilitate fast and effective bacteriocidal activity, was used on patients with venous leg ulceration. Results demonstrate that the dressing both stimulates healing and reduces the signs of infection.
