CHARACTERISTICS AND USES OF WOUND-DRESSING MATERIALS
| Category | Examples | Description | Applications |
|---|---|---|---|
| Alginate | AlgiSite, Comfeel, Curasorb, Kaltogel, Kaltostat, Sorbsan, Tegagel | Alginate dressings are made of seaweed extract contains guluronic and mannuronic acids that provide tensile strength and calcium and sodium alginates, which confer an absorptive capacity. Some can leave fibers in the wound if they are not thoroughly irrigated. These dressings are secured with secondary coverage. | These dressings are highly absorbent and useful for wounds have copious exudate. Alginate rope is particularly useful to pack exudative wound cavities or sinus tracts. |
| Hydrofiber | quacel, Aquacel-Ag, Versiva | An absorptive textile fiber pad, hydrofiber is also available as a ribbon for packing of deep wounds. This material is covered with a secondary dressing. The hydrofiber combines with wound exudate to produce a hydrophilic gel. Aquacel-Ag contains 1.2% ionic silver that has strong antimicrobial properties against many organisms, including methicillinresistant Staphylococcus aureus and vancomycin-resistant enterococci. | Hydrofiber absorbent dressings used for exudative wounds.. |
| Debriding agents | Hypergel (hypertonic saline gel), Santyl (collagenase) , Accuzyme (papain urea) | Various products provide some chemical or enzymatic debridement. | Debriding agents are useful for necrotic wounds as an adjunct to surgical debridement.. |
| Foam | LYOfoam, Spyrosorb, Allevyn | Polyurethane foam has absorptive capacity. | These dressings are useful for cleaning granulating wounds with minimal exudate.. |
| Hydrocolloid | CombiDERM, Comfeel, DuoDerm CGF Extra Thin, Granuflex, Tegasorb | Hydrocolloid dressings are made of microgranular suspension of natural or synthetic polymers, such as gelatin or pectin, in an adhesive matrix. The granules change from a semihydrated state to a gel as the wound exudate is absorbed. | Hydrocolloid dressings are useful for dry necrotic wounds, wounds with minimal exudate and for clean granulating wounds.. |
| Hydrogel | Aquasorb, DuoDerm, Intrasite Gel, Granugel, Normlgel, NuGel, Purilon Gel, KY Jelly | Hydrogel dressings are water-based or glycerin-based semipermeable hydrophilic polymers; cooling properties may decrease wound pain. These gels can lose or absorb water depending upon the state of hydration of the wound. They are secured with secondary covering. | These dressings are useful for dry, sloughy, necrotic wounds (eschar).. |
| Lowadherence dressing | Mepore, Skintact, Release | Low-adherence dressings are made of various materials designed to remove easily without damaging underlying skin | These dressings are useful for acute minor wounds, such as skin tears, or as a final dressing for chronic wounds that have nearly healed.. |
| Transparent film | OpSite, Skintact, Release, Tegaderm, Bioclusive | Transparent films are highly conformable acrylic adhesive films with no absorptive capacity and little hydrating ability. They may be vapor permeable or perforated. | These dressings are useful for clean, dry wounds with minimal exudate. They also are used to secure an underlying absorptive material, to protect high-friction areas and areas that are difficult to bandage (eg, heels) and to secure intravenous catheters.. |
