Topic Two: Fibrous Hydrocolloid Dressings (Gelling Fibres)
Composition & Properties
These dressings are usually comprised entirely of sodium carboxymethyl-cellulose (CMC) fibres, although they can also be a combination of a high percentage of CMC and other fibre types. The dressing functions by a hydrophilic action as it absorbs exudate by vertical wicking and has a rapid uptake of fluid directly into its fibres. The dressing becomes a soft, conformable gel and allows an increased amount of exudate to be absorbed and retained within the fibres (Morris, 2006; Edwards et al., 2013).
Fibrous hydrocolloids are indicated for the management of exuding wounds. They are best used in moderate to highly exuding sloughy and necrotic wounds. The dressing aids autolytic debridement of a wound and helps to provide an ideal environment for wound healing (Vuolo, 2009).
