it. The gauze covered with petroleum jelly have the advantage of not sticking to the wound. In the case of deep ulcers, the use of special bandages that contain a gelatinous material may favor the growth of new skin. If the ulcer appear to be infected or festering, rinse it, wash it gently with soap or use disinfectants such as povidone iodine can remove dead and infected material. However, clean it by rubbing it too can delay healing. Sometimes the doctor needs to remove (debride) dead matter with a scalpel (or scalpel). Instead of chemical agents may be used, but generally its effect is not as complete as that obtained using the scalpel. The pressure ulcers are difficult to treat. Some cases require transplantation of healthy skin to the damaged area. Unfortunately, this type of surgery is not always possible, especially in elderly, frail, which manifest malnutrition. It often happens when an infection develops in the depths of an ulcer, antibiotics are administered. The bones located beneath the ulcer can become infected and this infection (osteomyelitis) is extremely difficult to cure, can pass into the bloodstream and spread to other organs, requiring treatment with an antibiotic for several weeks.7 - Some products used to perform healing.
