Hydrofera Blue CLASSIC® Tunneling Dressings provide a sterile and antibacterial foam solution for sinus tracts and tunnels. The 9mm thick, open-celled Polyvinyl Alcohol (PVA) foam effectively wicks bacteria-laden exudate, slough, and debris, promoting wound cleansing. Broad-spectrum antibacterial protection from methylene blue and gentian violet reduces bioburden without impacting growth factors. The high tensile strength of these dressings allows for secure placement in challenging tunneling wounds and sinus tracts, and their design ensures easy, single-piece removal.

• Antimicrobial protection: Methylene blue and gentian violet combat a wide range of bacteria.
• Exudate management: Effectively absorbs and retains exudate, preventing maceration.  
• Tunneling design: Addresses complex wound challenges with targeted delivery.
• High tensile strength: Securely fills and conforms to wound cavities.
• Hydrate before use: Dressing must be hydrated for optimal performance and effectiveness.
