Why are prophylactic antibiotics used in battlefield injuries?

• A. To treat established infections
• B. To prevent allergic reactions
• C. To save cost
• D. To reduce risk of infection and sepsis in contaminated wounds

Answer: (D)

Prophylactic antibiotics are used in battlefield injuries to prevent infection and sepsis in contaminated wounds. In war, wounds are often dirty with soil and debris, tissue is damaged, and immediate definitive care may be delayed. Giving antibiotics early helps curb bacterial growth before an infection can become established, reducing the risk that the wound will become infected and progress to sepsis. They’re intended as a preventive measure, not a treatment for an already established infection, and they’re chosen to cover the likely foul-contaminant organisms found in battlefield injuries.
