Key Features of Sorbsan Flat Dressings

Description Sorbsan is made from the calcium salt of alginic acid, prepared as a textile fibre, and presented as a loose `rope' or packing for cavities, a ribbon for narrow wounds or sinuses, and a flat non-woven pad for application to larger open wounds. When in contact with serum, wound exudate, or solutions containing sodium ions, the insoluble calcium alginate is partially converted to the soluble sodium salt, and a hydrophilic gel is produced, which overlays the wound and provides a micro-environment that is believed to facilitate wound healing Indications Sorbsan sheets may be applied to exuding lesions including leg ulcers, pressure areas, donor sites, and most other granulating wounds but for deeper cavity wounds and sinuses, the packing and ribbon forms are generally preferred. The dressing also appears to be of value as an adjunct to the systemic treatment of infected or malodorous wounds and for the management of painful wounds when removal of other more traditional dressings causes unacceptable levels of pain or trauma. Contra-indications Although there are no known contra-indications to the use of Sorbsan, the dressing will be of little value if applied to wounds that are very dry, or covered with hard black necrotic tissue.
