They are thermally insulating and permeable to moisture vapour and atmospheric gases. They do not adhere to the wound, nor do they release any particles or toxic components into the wound. Foams are highly conformable and generally provide excellent cushioning and protection of the wound site. They can be used effectively under compression. They are available in many different shapes and sizes, including cavity fillers and can be cut to size.
Some brands are available in waterproof island dressings.
Indications Foams are extremely versatile and can be used on a wide range of wounds including lightly to moderate or highly exudating wounds and superficial or cavity wounds. Burns, leg ulcers, pressure wounds, simple wounds that are exudating, skin grafts or donor sites are all suitable candidates for foam dressings. They also have an important role as protective cushioning over bony prominences to prevent the development of pressure ulcers. Method of Application Foams are applied either directly to the wound, or as a secondary dressing. They can be cut to size, but the dressing should leave about 3-4cm clearance from the outer edges of the wound.
