Foam dressings are made from semi-permeable polyurethane and are non-adherent and non-linting. They create a moist environment effective for healing of wounds. Foam dressings allow entry of moisture but keep bacteria and other contaminants away from the wound site. It is available in various shapes and sizes with an outer layer may be water proof or hydrophobic. Certain dressings possess adhesive tapes, or borders, across the edge so that application can be made with greater ease. Foam dressings are available in pads, sheets as well as cavity dressings.
Foam dressings are meant for partial or full thickness wounds with moderate or greater drainage. This dressing type helps treat wounds with moderate amount of exudate such as abrasions, incisions, lacerations, pressure ulcers, infected wounds as well as draining peristomal wounds. It can be used either as a primary dressing or secondary dressing with the former more in direct contact with the wound and the latter used to cover the primary dressing.
