Wound Dressings Use Silicone Adhesive Technology

A range of wound care products provide a novel approach to wound repair, responding to basic needs for moist treatments, complex wounds, and nonhealing wounds.

The Askina range of foam dressing wound coverings for the care of chronic wounds enable optimal wound management, ensuring rapid formation of healthy granulation tissue and resulting in a complete wound closure. The product range covers each phase of the wound healing with an appropriate dressing, utilizing different technologies. Advanced ionic silver alginate technology also provides therapeutically efficacious products that reduce bacterial load, promotes faster healing, and rapidly reduce odors.

Among the products in the range are the Askina hydrogel wound dressing, which is used to donate fluid when used on dry to low exuding wounds, but that also absorb exudates from low to moderately exuding wounds. A special delivery system uses a cannula to reach deeper wounds, such as fistulas and tunnels. The Askina Hydro hydrocolloid dressings are used to absorb wound exudate by forming a gel, enhancing a moist wound environment conducive to natural healing. The hydrocolloid layer contains Psyllium husk, caboxymethylcellulose, and polyisobutylene; a polyurethane backing is water vapor permeable and bacteria resistant.

The Askina SilNet is a thin, porous, soft silicone wound contact layer, consisting of a conformable nonwoven material, coated on both sides with a soft silicone layer. It is designed to protect the wound site from the mechanical disruption during dressing changes by preventing adhesion of the secondary dressing to the wound surface, minimizing the trauma associated with dressing changes; its porous structure allows vertical passage of exudate into the secondary absorbing dressing. Askina SilNet can be left in place for several days, as long as the exudate passes freely into the secondary dressing.

The Askina Calgitrol Ag is a silver alginate wound dressing that incorporates the barrier effectiveness of ionic silver with the absorbency capabilities of calcium alginate and polyurethane foam. A patented matrix formulation combines calcium alginate and silver alginate with 10% of bonded water. In contact with exudate, an alginate matrix forms a soft gel, allowing the liberation of silver ions and providing a moist wound environment conducive to natural healing. The Askina line of products also includes thin hydrocolloids, charcoal dressings, hydrocellular dressings, calcium alginates, and polyurethane films. All products are made by B. Braun Medical (Sempach, Switzerland).

"Silicone technology provides a new standard of a traumatic wound care treatment whilst for infected wounds, the patented ionic silver alginate matrices provide a broad antimicrobial effectiveness and help to prevent contamination from external bacteria,” said Claude Regnier, international marketing director of B. Braun Medical.
