Since they perform the same functions, gauze sponges and gauze pads are interchangeable in most ways. Both products are available in a woven cotton or poly rayon material, sterile or unsterile. Also, with about the same ply, they are more absorbent and more robust than other dressings, and they are excellent for packing or cushioning a wound. The only difference between the two is the packaging. Gauze pads are available one per pack, and gauze sponges come in packages of two or more.
