Treatment of a contaminated wound typically involves several steps: 1. Cleaning the wound thoroughly with sterile saline solution to remove debris and bacteria. 2. Debridement, which is the removal of dead tissue to promote healing. 3. Application of antiseptic or antibiotic ointments to prevent infection. 4. Closing the wound with sutures or staples if necessary, although some wounds may be left open to heal from the inside out. 5. Administering systemic antibiotics if the risk of infection is high. 6. Regular dressing changes to keep the wound clean and promote healing.
