Superficial second-degree frostbite is that which extends through the full thickness of the skin.
Frostbite occurs when the skin and body tissue are exposed to cold temperature for a prolonged period of time.
They cause redness, fluid accumulation and significant swelling of the area, bulging in the form of a small pouch filled with clear fluid and blisters that flake off and form a blackish crust with loss of sensation. They are very painful since the nerve endings are yet to be affected.
A detailed clinical history and complete physical examination are required to reach a diagnosis.
Superficial frostbite is treated on an outpatient basis and the common treatment for any degree of frostbite is aimed primarily at avoiding aggravation of the clinical picture and at restoring blood circulation to the affected area.
