Alginate
Derived from brown seaweed; conform to shape of wound
Alginates
provides moist environment & thermal insulation
Foam dressings
Used when moist environment is needed to allow clean wounds to granulate
Hydrocolloid dressings
allows exudate to flow through to secondary dressing; protects wound.
Contact layers
May absorb and also cover a wound, for example
Composite dressings
Topical derived from silver, iodine, and poly-hexamethylene biguanide.
Antimicrobial dressings
For colonized wounds; has antimicrobial & anti-inflammatory properties
Honey
Adhesive semipermeable polyurethane membrane dressings; waterproof and impermeable to bacteria
Transparent films
Water or glycerine-based amorphous gels, impregnated gauzes
Hydrogels
Combine two or more distinct products into a single dressing
Composite dressings
Collagen is the most abundant protein in the body
Collagen dressings
Woven or nonwoven material impregnated with substances iodinated agents, petrolatum, zinc, bismuth
Impregnated gauze
waterproof and impermeable to bacteria and contaminants yet permit water vapor to cross the barrier.
Transparent films
Used for variety of conditions, depending on agent added to dressing.
Impregnated gauze
used to stimulate new tissue development
Collagen dressings
Oxidized regenerated cellulose and collagen.
Promogran matrix
when a moist healing environment is needed to promote granulation and epithelialization
Hydrogels
Sterile products that absorb exudate and conform to the shape of the wound bed
wound fillers
Occlusive or semiocclusive dressings made of pectin, gelatin, and carboxymethylcellulose.
Hydrocolloid dressings
used in draining, nonhealing wounds w/ bacterial contamination. e.g. burns, surgical wounds, diabetic ulcers, pressure injuries
Antimicrobial dressings
Nonadherent dressing layers often used with other products.
Contact layers
Absorbent; some have a film coating and adhesive border
Foam dressings
uses the body's own enzymes and moisture to rehydrate, soften and liquefy devitalised tissue.
autolytic debridement
Medical grade honey used in a variety of dressing types.
Honey
packed into wound, absorbs exudate; forma soft gel maintains moist environment for wound healing
