Abstract
A method for dressing wounds to prevent adherence of the covering dressing to the wound includes applying a surfacing barrier (20) as an interpositional material between the wound and covering dressing. The barrier is an extruded, nonwoven polymeric material permeable to blood and serum and having an air permeability between about 300 and about 1140 ft..sup.3 /min./ft..sup.2 and a thickness of between about 0.5 mils to about 3.0 mils. The barrier is positioned over the wound and surrounding area and conformed to the shape of the body being treated. The covering dressing is then applied over the barrier.
