Gelfoam is a material used in fresh open wounds to stop bleeding. The Gelfoam is put directly on the base of the wound. It helps the blood to form a clot. Another bandage is put on top of the Gelfoam to protect it and keep it in place.
The Gelfoam material that touches the wound base will dissolve or fall off with the scab. Any Gelfoam that’s left may be taken off during a follow-up visit.
