Calcium Alginate Dressings

Calcium alginate is derivate from seaweed. It is highly absorbent and gradually forms a moist soft gel in contact with sodium ions of wound exudates.
 Alginate is a collective term for a family of polysaccharides synthesized from brown algae and bacteria. Alginic acid was first discovered, extracted, and patented by Stanford.

Alginate dressings are absorbent, nonadherent, biodegradable, nonwoven fibers derived from brown seaweed. They are composed of calcium salts of alginic acid and mannuronic and guluronic acids. Alginate dressings in contact with sodium-rich solutions such as wound drainage impose the calcium ions to undergo an exchange for the sodium ions, forming a soluble sodium alginate gel. This gel maintains a moist wound bed and supports a therapeutic healing environment.

Alginates can absorb fluid 20 times their own weights that can vary based on the particular product. They are extremely beneficial in managing large draining cavity wounds, pressure cavity ulcers, vascular ulcers, surgical incisions, wound dehiscence, tunnels, sinus tracts, skin graft donor sites, exposed tendons, and infected wounds. Furthermore, their hemostatic and absorptive properties make them efficient treatments for bleeding wounds. Alginates are contraindicated for dry wounds, eschar-covered wounds, surgical implantation, or on third-degree burns1.

Main component: Calcium Alginate

    Does not adhere to the delicate healing tissue can be easily removed.
    creates a moist wound environment at the wound surface
    No irritation, no sensitivity (ISO 10993-10)

Instructions for use:
Calcium alginate dressing should be changed when it formed to gel. In early stages, change dressing every 24 hour then by reducing exudates and by beginning of healing process, it should be changed every 48 hour.
