Which management step is central to treating trench foot and chillblains?

• A. Elevation, warming and bandaging
• B. Cold immersion
• C. Oral antibiotics
• D. Pressure therapy

Answer: (A)

Prolonged cold exposure causes trench foot and chillblains through vasoconstriction, tissue hypoxia, and edema, so the central management is to restore perfusion safely while protecting the skin. Elevating the affected limbs reduces venous congestion and edema, alleviating pain and helping return blood flow. Warming should be gradual and in a dry, warm environment using ambient heat or warm (not hot) water to avoid burns or further tissue injury. Protective bandaging helps keep the skin intact, prevents secondary infection, and maintains a barrier against further cold exposure. Cold immersion would worsen the injury by exposing tissue to more cold and delaying proper rewarming. Oral antibiotics are not routinely needed unless there is an evident infection, and pressure therapy is not a standard treatment for these conditions.
