Silicone Heel Foam
Although the film is permeable to moisture vapour, it provides an effective barrier to water or wound exudate and also prevents the passage of microorganisms through the back of the dressing.
The wound contact surface is covered with a perforated film, designed to prevent it from adhering to fragile new tissue.
When applied to an exuding wound, the foam layer absorbs excess fluid, but as exudate production decreases, the film backing regulates the evaporative loss of moisture and stops the dressing from drying out completely.
In this way the dressing maintains the wound in a moist condition and thus provides a micro-environment that is conducive to healing.
Silicone Heel Foam may be applied to a variety of granulating wounds on difficult to dress areas such as heels, elbows, stumps, scrotums, babies’ heads and other anatomical areas where a flat dressing is not appropriate.
No absolute contra-indications to the use of Silicone Heel Foam have been reported, but the dressing will be of limited value if applied to dry wounds such as those covered with a scab or hard black necrotic tissue. Before application of the dressing this should be removed, either surgically, or by some other means.
Method of use
After cleansing the wound in accordance with normal practice, the dressing is applied with the inner white layer in contact with the wound and the pink surface facing outwards. The dressing, which can be cut if necessary, may be secured with a bandage, surgical tape or some other suitable adhesive product, taking care not to occlude the semi-permeable outer membrane.
Frequency of Change
The frequency with which Silicone Heel Foam should be changed depends upon the nature of the wound and the amount of exudate produced. On a clean non-infected wound, it may be left in position for up to seven days, but more frequent changes will be required on infected or heavily exuding wounds.
