Cold Emergencies: Understanding Frostbite and Hypothermia
Preparing for the overlooked peril: make sure your provisions are ready
In the cold winter months, two potentially dangerous conditions can arise: frostbite and hypothermia. While both are related to exposure to cold, they differ in their causes, symptoms, and treatment.
Differences and Symptoms
Frostbite occurs when skin and underlying tissues freeze due to prolonged exposure to cold temperatures. It usually affects extremities such as fingers, toes, nose, ears, cheeks, and chin, causing localized injury to the skin and deeper tissues. Symptoms include numbness, white, pale, grayish-yellow, or waxy skin, skin that feels firm or hard, blisters in second or third-degree frostbite, and pain especially after rewarming.
On the other hand, hypothermia is a systemic condition that occurs when the core body temperature drops below normal (below 95°F or 35°C), caused by prolonged exposure to cold. It affects the whole body, causing symptoms such as uncontrollable shivering that may stop as the condition worsens, poor coordination, slurred speech, confusion, lethargy, apathy, slow, shallow breathing, weak pulse, and, in severe cases, unconsciousness and death if untreated.
First Aid Measures
For frostbite, it's crucial to avoid rubbing or massaging affected areas as this can cause further tissue damage. Instead, protect the affected areas by covering them gently and keep them covered while warming. Rewarm the affected areas in water that is just above body temperature (around 37-40°C or 98-104°F) until the numbness and whiteness disappear. Remove wet clothing and cover with warm, dry clothing, and keep the person sheltered from further cold exposure. Seek emergency medical care especially for second-degree or worse frostbite, which may require thrombolytic therapy and further interventions.
For hypothermia, move the person to a warm environment (warm room or shelter) and remove wet clothing, replacing it with dry, warm coverings like blankets. Warm the body core gradually using warm (not hot) blankets or skin-to-skin contact (e.g., armpits or groin). Provide warm, non-alcoholic beverages if the person is conscious and able to swallow. Avoid rapid rewarming of limbs first; focus on core warming to prevent shock. Avoid direct heat sources that can burn or cause irregular heart rhythms. Get emergency medical help immediately as hypothermia can be life-threatening.
