A randomized, controlled, parallel group clinical trial of a polyurethane foam dressing versus a calcium alginate dressing in the treatment of moderately to heavily exuding venous leg ulcers

A polyurethane foam dressing and a calcium alginate dressing were compared in the treatment of moderately to heavily exuding venous leg ulcers in a pa rallel group study of 63 patients. Dressings were changed as evidenced by l eakage from the wound but could remain in place for a maximum of seven days . Although similar performance was seen in terms of exudate absorption, the polyurethane foam dressing was superior in terms of sticking to the wound, leakage, causing wound odor, and patient comfort.
