For clinical frostbite caused by icing, the first step should be to temporarily stop icing and give immediate rewarming. Most frostbite caused by icing is relatively mild, such as first- or second-degree frostbite. For first-degree frostbite, the wound should be kept clean and dry to prevent pressure, and it will heal spontaneously within a few days. For second-degree frostbite, soft gauze can be applied when the wound is dry and clean to avoid local friction and pressure. If large blisters appear, they should be disinfected with iodophor and aspirated under sterile conditions, with the blister skin preserved and wrapped with sterile gauze. When the trauma is infected, wet dressing with gauze soaked with antibacterial drugs can be applied, followed by frostbite cream and treated by bandaging or semi-naked method. In addition, for patients with second-degree frostbite, local medications to improve microcirculation and anticoagulants, such as low molecular dextran, may be considered. If the pain is obvious, oral non-steroidal anti-inflammatory drugs can also be given, and in severe cases, painful spots can be closed, etc.
