Sorbsan Plus Surgical Dressings Sorbsan Plus Surgical Dressings consist of a layer of alginate fibre bonded on to an absorbent viscose pad which in turn is backed with a pink viscose/polyester layer to indicate the outer surface of the dressing. 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 Sorbsan Plus Surgical Dressings have the same general indications as the regular Sorbsan Surgical Dressings, for example leg ulcers and pressure areas, but is particularly indicated for heavily exuding wounds. Directions Sorbsan Plus Surgical Dressings are applied to the wound and held in place with tape or a suitable bandage. Secondary dressings are not usually required because of the extra absorbency imparted by the integral absorbent pad. It has been reported that a small percentage of patients experience a mild `drawing’ or `burning’ sensation immediately after the application of an alginate dressing to a dry wound bed. This sensation, which is usually transient, is thought to be due to the hydrophilic nature of the dressing causing temporary localised drying of the surface of the wound. In most instances, this discomfort may be prevented by moistening the surface of the wound with a small quantity of sterile normal saline immediately prior to the application of the dressing. The interval between dressing changes will depend entirely upon the state of the wound. When applied to heavily exuding or sloughy wounds, Sorbsan Plus Surgical Dressing may need replacing daily at the beginning of treatment but as healing progresses and the amount of exudate decreases, the interval between changes may be extended to two or three days.
