AQUACEL Ag Dressings. AQUACEL Ag dressings are antimicrobial primary dressings for use in wounds that are infected or at risk of infection. They are designed to manage the 3 key local barriers to healing - exudate, infection and biofilm. AQUACEL Ag dressings incorporate proven Hydrofiber Technology and Ag Technology - a unique ionic silver-containing, antibiofilm formulation. AQUACEL Ag dressings are available as AQUACEL Ag Extra and AQUACEL Ag Ribbon dressings. AQUACEL Ag Extra dressing is comprised of 2 layers of Hydrofiber Technology stitch bonded together making it 9x stronger and 50% more absorbent than standard AQUACEL Ag dressing. AQUACEL Ag Ribbon dressing is also strengthened with stitchbonding.
