Gentell Gelling Fiber Dressing (formerly Gentell CMC Fiber Dressing) is a carboxymethylcellulose absorptive dressing for wounds with moderate to heavy exudate. A reaction between the fiber in the dressing and the wound fluid creates a gel-like substance that promotes moist wound healing and the formation of granulation tissue. The gelling fiber facilitates the removal of dead, damaged, and infected tissue from the wound and manages drainage to reduce the risk of periwound maceration.
