Spray on skin proves helpful for healing leg ulcers.
August 5, 2012 – According to researchers from Canada and the U.S., a spray on skin putting a covering of skin cells over a wound could help in the healing process. Researchers tested the spray on 228 people who had leg ulcers, which are open wounds that are very painful and can take months to heal. The researcher’s findings were recently published and found that the ulcers that had been treated with the spray were more apt to heal and to heal quicker.
Experts believe the quicker healing would save money even despite of the high cost of the spray. Ulcers on the leg are very difficult to treat. Compression bandages are the best way to treat them, but will only heal around 70% of ulcers following six months of treatment. There are other options such as lifting skin from another location on the person’s body and grafting it on top of the wound.
The spray coats the area of the wound with skin cells and proteins that help in blood clotting. The study’s participants who received the spray once every two weeks showed the best improvement. Researchers said the wound’s size decreased as soon as the spray was applied. Of the patients who received the spray, 70% were healed entirely in three months. That was compared to just 46% that was given other type treatment.
Healthpoint Biotherapeutics from the U.S. developed the spray and funded the study.
