Dressings and Wound Care. Help wounds to heal and prevent further issues like infection or complications. Dressings are designed to be in direct contact with the wound, which is different from a bandage that holds the dressing in place. Dressings serve a variety of purposes depending on the type, severity and position of the wound. Aside from the major function of reducing the risk of infection, dressings are also important to help stop bleeding and start clotting so the wound can heal.
