My dr put sodium on an open wound that will not heal. what does that do?

Superfast healing: The real question is what not to do that slows down healing. Avoid using alcohol, peroxide, hibiclens, betadine, and bleach solutions. Inflammation ( red, hot, swollen, tender) is important to healing so anti-inflammatories (motrin, advil) are bad. Cover the area with a clean dressing changed every other day and protected from trauma. Antibiotics do not help healing unless it is truly infected.

Not sure: He may have cleaned the area with sodium chloride. A salt solution. Wash with plain old soap and water. Cover with antibiotic ointment. Cover with a secondary dressing.
