Alginates are used as foam, clotting agents and gauze in absorbable surgical dressings and packing.
Wound care
Alginate dressings are derived from seaweed made of soft non-woven fibres, and are available as pads, ropes or ribbons. Alginate dressings are extremely lightweight, absorb many times their own weight, form a gel-like covering over the wound, and maintain a moist environment. They are best used for wounds with significant exudate.

Especially useful for packing exudative wounds; do not physically inhibit wound contraction as does gauze; highly absorbent.
Requires a secondary dressing; too drying if wound has little exudate.
