Foam dressings are extremely absorbent and were first introduced approximately 25 years ago. These dressing are generally made up of polyurethane, and also silicone, and are available is different shapes, sizes and compositions. Foam dressings are soft and cushion-like absorbent dressing for granulating wounds of different etiologies and intensity. Also, these dressings are gas-permeable, give thermal insulation and assist in maintaining a moist wound environment. Foam dressing can be used as either primary or secondary dressing on different types of wound, ranging from leg ulcers to cavity wound where exudation is a problem. Dissimilar to gauze, foam dressings do not cast off fibers particles, and therefore depending on their preparation they can be used on light, moderate or heavy wounds. Furthermore, foam dressings can be left in a wound for several days without causing any kind of softening and thereby increasing their cost-efficiency. Let us put some light on a few advantages of foam dressings.
Advantages of Foam Dressings are that, they…
…do not stick to the wound directly
…act as cushion to protect the wound
…can be used in case of an infection
…might be used at the time of compression therapy
…are suitable for wounds with hypergranulation
A wide range of foam dressings which include both self-adhesive and non-adhesive, is available and their quality to adjust and match according to the size and shape of a wound makes them predominantly useful for cumbersome anatomical surfaces such as heel and sacrum. Based on the composition, foam dressings have the ability to absorb and soak-up form light to heavy amounts of fluid which oozes from the wound. Also, because these foam dressings help in maintaining a moist environment, they can be removed with bare minimum to no pain. Foams are versatile materials which can be used in combination with other dressing materials, e.g., for diabetic foot ulcers, compression bandages are used along with foam dressings.
