  5. 5.Severe Frostbite of the Lower Limbs

    Frostbite is tissue damage caused by exposure to the cold (at or below 32F or 0C). It is most commonly found in people doing leisurely activities like camping, hunting, or snow sports. It is also more likely in those who are intoxicated or have a mental disorder.

If rewarming can occur without chance of refreezing, it can be tried in the field. There, the doctors will guide you in gently re-warming the wounded area in 98-102F (37C-39C) water. Further, ibuprofen, antibiotics, a tetanus shot, and possibly surgery will be done to treat the pain and dead tissue. IV fluids will also be started. Hydrotherapy will be done daily to help with the wounded area.
