Alginate dressings are made soft non-woven fibers which are derived from seaweed. These dressings are capable of absorbing large amounts of wound drainage. As alginates absorb drainage, they form a gel-like covering over the wound, which maintains a moist environment that is optimal for healing. During dressing changes, the gel can be rinsed or soaked away with saline, allowing removal of the dressing without re-traumatizing the wound bed and minimizing pain.
Alginate dressings are also available with silver (AG). Alginate AG dressings are effective against a broad spectrum of bacteria and fungi.
