Introduction: The management of infected wounds and those wounds at risk from
infection is a key parameter in the Healthcare professional’s objectives. Jones et al1
reported that good clinical practice should include the correct choice of wound dressing
to prevent and manage local infections in at-risk wounds. As such, antimicrobial activity
both within the dressing and at the wound interface needs to be considered. The aim of
this study was to examine the antimicrobial activity at the dressing/wound interface of
silver-containing wound dressings.
Methods: An agar plate model previously reported by Jones et al 20051 was assessed
to investigate antimicrobial activity of different dressing types following intimate contact
with a surface-inoculated agar plate.
The model used a nonwoven fabric to create an impression within the surface of the
agar plate. Two challenge organisms were used methicillin-resistant Staphylococcus
aureus (MRSA) and Pseudomonas aeruginosa. Following incubation each dressing was
removed from the agar plate and visual examination of the microbial activity within the
agar impression was undertaken.
Discussion: This study utilised two fluid doses to assess whether this had an effect. It
was observed that some dressings performed differently dependent of the doses of fluid
whilst other dressings the performance was not affected by the dose level. The wound
dressings with no silicone on the wound interface exhibited antimicrobial activity whilst
those with silicone did not.
Conclusion: The Polyurethane foam dressing with no silicone wound interface
demonstrated the greatest antimicrobial efficacy at both the lower and higher exudate
levels.
