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 parallel group study of 63 patients. Dressings were changed as evidenced by leakage 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.
