Hard-to-heal wounds
Infection and Biofilm Management
In the battle against hard-to-heal wounds, there is an invisible enemy, Biofilm.
MORE THAN SILVER™ technology
A major barrier to wound healing, biofilm is present in at least 78% of hard-to-heal wounds. 1
Thanks to our breakthrough MORE THAN SILVER™ technology - which contains ionic silver together with a surfactant and a metal chelating agent - our dressing delivers superior2 antibiofilm performance compared to other tested silver dressings.
A Multinational Randomised Controlled Trial3
Effectiveness of an enhanced silver-containing dressing in hard-to-heal venous leg ulcers: a randomised controlled trial3
Evidence shows Aquacel Ag+ Extra™ effectively disrupts and destroys biofilm4,5 with Aquacel® Ag+ Extra™ achieving superior complete wound closure vs DACC dressings in an RCT.3
A Health Economic Publication6
Management of VLUs with Aquacel® Ag+Extra™ versus Cutimed® Sorbact® was associated with
✓ Higher rate of and shorter time to complete wound closure.
✓ Reduction in the total cost of leg ulcer management.
✓ Improvement in HRQoL.
NICE-published cost comparison
The NICE Late Stage Assessment includes a health economic analysis of infected leg ulcers using different types of antimicrobial agents. NICE reviewed cost-modelling shows Aquacel® Ag+ Extra™ saves >£500 per patient to treat an infected leg ulcer.⁷
