Clinical evaluation of a polymeric membrane dressing in the treatment of pressure ulcers

The healing effects of the Ferris polymeric membrane dressing were tested in a 70-day evaluation of 18 ulcers on 13 elderly subjects with Stage I, II, and III pressure ulcers. The mean length of time these ulcers had been present prior to the trial dressing was 144 days with 50% of the ulcers (n = 9) present for 75 days or longer. Over 60% of the ulcers were completely healed and over 94% were improved during the study.
