An adhesive dressing for use on moist wounds which comprises a pressure sensitive adhesive-coated wound contacting first layer in which there are present holes capable of transmitting liquid water and a moisture vapor permeable, continuous film. The continuous film is attached to the first layer in such a way as to form a reservoir into which water can pass through the holes in the first layer and can evaporate from the reservoir through the continuous film. The adhesive coated first layer has a moisture vapor permeability of less than 300 gm-2 24 hr-1 at 37°C. and 100% to 10% relative humidity difference and the continuous film has a moisture vapor permeability which is greater when in contact with liquid water than when not in contact with liquid water. Optionally, an intermediate water transmitting layer may be present between the first layer and the continuous film.

An adhesive dressing suitable for use on moist wounds which dressing comprises a pressure sensitive adhesive-coated wound contacting first layer which has holes therethrough capable of transmitting liquid water and a moisture vapour permeable continuous film attached to the non-wound contacting surface of the first layer thereby forming a reservoir into which water can pass and evaporate therefrom, said adhesive coated first layer being of a material which has a moisture vapour permeability in the absence of holes therethrough of less than 300 gm-2 and 24 hr-1 and said moisture vapour permeable continuous film having a moisture vapour permeability which is greater when in contact with liquid water than when not in contact with liquid water.
