Another common type of dressing is foam dressings. Foams are made of foamed polymer, usually polyurethane, and made into sheets or other shapes. They have open cells which can hold fluids, enabling absorbency. But the extent of absorbency is based on the thickness and composition of the foams. Foams absorb the excess fluids as well as keep the area moist at the same time, allowing for faster healing as well. The ultra-soft nature of the material also helps cushion the injury, protecting it from further harm.
These dressings can sometimes come pre-soaked in solutions, or combined with other materials. Foams come in many shapes and sizes. They can easily be removed because the contact with the wound is non-adhesive. Foams can come with an adhesive border, often with a coating of a protective transparent film that helps prevent bacteria from entering but allows water vapor to enter. This aids in maintaining adequate moisture for the wound’s healing.
Best Uses: Foams help prevent bad odors, as well as moderate to heavy discharge. They are ideal for both partially-thick and full-thickness wounds, and both serious and unserious wounds. You can also use foams for pressure injuries.
