Areza Carboxymethyl Cellulose (CMC) Gelling Fiber is a primary wound dressing made from medical grade sodium carboxymethyl cellulose (CMC). The pad/dressing turns into a hydrophilic gel as it comes to contact with wound fluid (exudate). The newly formed gel is soft and provides an optimal moist wound healing environment, can conform to the wound bed, and by loosening the non-live material over the wound (autolytic debridement) reduces the need for physical debridement. Areza CMC gelling fiber absorbs the wound fluid in a very unique vertical direction called "vertical absorbency", a capability which may reduce the risk of maceration by reducing the horizontal spread of the wound fluid to the other parts of the dressing. This dressing is ideal for moderate to highly leaking (exuding) wounds. CMC also reduces the risk of infection by creating a physical barrier to external contaminants and microscopic organisms. The non-adhesive formed gel reduces the risk of wound trauma during dressing changes.
