An alginate dressing is a natural wound dressing derived from different types of algae and seaweed. These non-woven dressings are made from soft fibers that can absorb up to 20 times their weight in fluid.
What are alginate dressings used for?
Alginate dressings are commonly used on wounds producing a significant amount of exudate. Some examples include pressure ulcers, diabetic wounds, and partial thickness burns.
Many alginate dressings contain sodium and calcium, which absorb large amounts of exudate to prevent maceration. These dressings form a gel when ithey come into contact with drainage. Alginates conform to the shape of the wound, allowing all areas to heal. They protect against bacterial infection while maintaining a moist healing environment. Alginate dressings are naturally biodegradable.
