How to treat a liquefied gas frostbite

After being frostbitten by liquefied gas, it is essential to immediately leave the cold environment, rapidly rewarm the affected area, protect the injured site, prevent infection, and monitor changes in condition. Scientific management can reduce tissue damage and lower the risk of complications. If frostbite occurs, prompt medical attention is recommended.

1. Immediately leave the cold environment: Quickly move away from the source of leaking liquefied gas to avoid further exposure to the cold gas. Close the liquefied gas valve to prevent additional leakage, and transfer to a warm, dry indoor area to minimize continued cold exposure and prevent worsening injury.

2. Rapid rewarming: Immerse the frostbitten area in warm water at 37°C–40°C for approximately 15–30 minutes, or until the skin regains a pinkish color and sensation gradually returns. Avoid using hot water or direct heat (such as fire), as excessive temperature differences may cause tissue damage.

3. Protect the frostbitten area: After rewarming, gently pat the affected area dry with a clean, soft towel. Avoid rubbing or applying pressure. If blisters are present, do not puncture them yourself. Cover them lightly with sterile gauze to prevent rupture and reduce the risk of infection.

4. Prevent infection: If the skin is broken, apply an antibacterial ointment such as mupirocin once or twice daily. Keep the wound clean and dry, avoid contact with dirty water or contaminants, and reduce the risk of bacterial infection to promote healing.

5. Monitor for changes in condition: Closely observe the color, temperature, and sensation of the frostbitten area after rewarming. Signs such as purple or black discoloration, increased swelling, severe pain, or fever may indicate worsening frostbite, requiring immediate further medical intervention.

In daily care, ensure the frostbitten area stays warm to avoid re-exposure to cold. Wear loose, breathable clothing to minimize friction, and consume a diet rich in vitamins and protein to support tissue repair.
