Bandages infused with electricity can help heal wounds faster than typical bandages or antibiotics—but for years, researchers have not really understood why. A recent study by a team at The Ohio State University is offering new clues about the science behind those bandages, and researchers say the findings could help lead to better wound treatment.
Each year, approximately 5 million patients in the United States receive treatment that includes the insertion of a medical device such as a catheter, which puts them at increased risk of potentially life-threatening infection. Researchers have found a strategy that greatly reduced both overall infection and infection with antibiotic-resistant bacteria in a group of these patients. The results of their study were published today in the online issue of The Lancet.
