It is important to take the right steps after meeting a frostbite patient because improper handling will not only not allow the patient to mitigate the damage in time, but will cause them to suffer more damage. The first step is to quickly get out of the cold environment and prevent further freezing. The basic treatment is all about revolving around the goal of rapid rewarming and preventing further cold exposure as well as restoring blood circulation. In the early stages, the frozen area can be covered with clothing or warm hands, or other body surfaces can be kept at the proper temperature to maintain adequate blood supply. In the second step, a water bath can be used to rewarm the area, with a water temperature of about 40 degrees, and a frozen cream can be applied locally. Anti-shock and anti-infection in the process of treatment, do not rewarm too quickly and too rapidly when there is a respiratory heartbeat, otherwise it will easily cause arrhythmia and ventricular fibrillation, etc.
