[Skin wound granulation from contact with synthetic foil of teflon-polyurethane type].

When a plastic-foil consisting of teflon-polyurethan foam is applied to ulcer cruris and to polyurethan foam is applied to ulcera cruris and to combusted skin, pronounced granulation and formation of new capillaries and collagen fibers are observed in the contact area. The tightly adhering foils are tolerated by the wounds for more than 40 days with continous granulation. An adverse reaction against the foreign material and development of eosinophils and giant cells is not observed, though the polyurethan-foam of the foil was burst by the ingrowing granulation tissue. When the wound surface is clean, change of the dressing with this foil is necessary only every second or third day.
