When should IV antibiotics be started for open fractures?

Open fractures carry a high risk of infection because contaminated environment and exposed tissues can rapidly seed bacteria. Giving IV antibiotics as soon as possible after injury helps curb bacterial growth and lowers the chance of infection, with the fastest protection seen when antibiotics are started within the first hour. This timing matters because it complements urgent surgical debridement and irrigation—the definitive step to remove contaminated tissue—without waiting for debridement to begin antibiotic therapy. Waiting for imaging or postponing antibiotics until after the wound is debrided delays this critical protective measure and increases infection risk. So, starting intravenous antibiotics within one hour of injury provides the best balance of rapid protection and definitive care.
