Alginate dressing

Gel formation is via ion exchange of sodium in serum for calcium within the alginate dressing. A biodegradable gel is formed when the fiber is in contact with exudate, and the released calcium contributes to the clotting mechanism. The gel may be firm or soft depending upon the proportions of calcium and sodium in the fiber. It is removed with saline.
