Recalling my pharmacy assistant wound dressing training....I would say its opsite that they would use, also known as second skin. (opsite is brand name, made by smith and nephew)
there is a trick to removing it squid! gently lift one corner and pull it taut, strteching it across the area, keeping it close to the surface, it should come away easily and just lift off. ask at the hospital for them to show you how to get it off painlessly, they should know how!
