Foam dressings are sheets of foamed polymer solutions (most commonly polyurethane) with small, open cells capable of holding fluids. They are layered in combination with other materials. Absorption capability depends on thickness and composition. The area in contact with the wound surface is non-adhesive for easy removal. Available with an adhesive border and/or a transparent film coating that acts as a bacterial barrier. Indicated for partial and full-thickness wounds.
A wound covering typically in the form of a multi-layered pad having a material or substance on its skin-contact surface (e.g., silicone gel), or designed to be soaked in saline prior to application, to prevent adherence to the wound bed thereby decreasing wound trauma potential; it does not contain an antimicrobial agent. It is typically used to absorb wound blood/exudates while protecting the wound from external contamination and maintaining a moist internal environment. It may be used as a primary or secondary dressing to treat chronic and postoperative wounds, burns, ulcers, abrasions, cuts, or puncture sites; it is not a dedicated burn dressing. This is a single-use device.
