Specialized Wound-

Specific Dressings

Specialized dressings are often used in conjunction with other advanced wound care technologies. These specialized wound coverings are made from materials specifically designed to absorb fluids and protect the open skin while accelerating wound repair and reducing complications during the healing process. Specialized dressings used at Houston Methodist include: 

  • Alginates absorb the fluids leaking from the wound and form a gel-like covering over the wound, maintaining a moist environment that promotes effective healing. Although most alginates absorb many times their own weight, the dry dressing itself is extremely lightweight. 
  • Biologic gels, solutions or semi-permeable sheets are derived from a natural source that closely resembles human skin in structure. 
  • Cellulose derivatives are nongelling materials that are able to absorb fluids without permanently bonding to the skin. 
  • Collagen dressings are specially formulated nonadhesive dressings that are not airtight or watertight. 
  • Composites consist of multiple layers of dressings that serve different functions, such as serving as a barrier against bacteria, absorbing fluids and adhering to the skin. 
  • Foamed solutions applied in sheets and other shapes, contain small, open cells capable of holding fluids. 
  • Hydrocolloids are available as wafers, powders or pastes composed of specialized materials that create a watertight seal. 
  • Hydrofoams are highly absorbent, and can absorb large amounts of fluids that leak from the wound. 
  • Silver impregnated gauzes and non-woven sponges, ropes and strips are saturated with silver and other materials to prevent bacteria from entering the wound.


Dressings are individually selected by your care team at Houston Methodist. Our specialized staff will work with you to create a treatment plan to accelerate the healing process and address any underlying problems affecting wound healing.
