The first step in treating frostbite is to gently rewarm the affected area. This should be done using warm (not hot) water, ideally between 37°C to 39°C (98.6°F to 102.2°F). The affected area should be submerged for 30 to 45 minutes until normal color and sensation return. Avoid direct heat sources, as they can cause burns[2].

2. Avoiding Further Injury

Patients should be advised to avoid walking on frostbitten feet or using hands that have been affected. This helps prevent further damage to the tissues[2].

Medical Treatment

1. Pain Management

Pain associated with frostbite can be severe. Analgesics, such as non-steroidal anti-inflammatory drugs (NSAIDs) or opioids, may be prescribed to manage pain effectively[2].

2. Hydration and Electrolyte Balance

Intravenous fluids may be necessary to maintain hydration and correct any electrolyte imbalances, especially in severe cases where systemic effects are present[2].

3. Antibiotics

If there is evidence of infection or if necrosis is present, broad-spectrum antibiotics may be initiated to prevent or treat infections[2].

4. Tetanus Prophylaxis

Patients with frostbite should be assessed for their tetanus vaccination status. If they are not up to date, a booster may be administered[2].

Surgical Intervention

1. Debridement

In cases where necrotic tissue is present, surgical debridement may be necessary to remove dead tissue and promote healing. This can help prevent infection and facilitate the recovery of healthy tissue[2].

2. Amputation

In severe cases where the tissue is irreversibly damaged, amputation of the affected digits or limbs may be required. This decision is typically made after careful evaluation of the extent of tissue loss and the potential for recovery[2].

Rehabilitation

1. Physical Therapy

Post-treatment rehabilitation may include physical therapy to restore function and mobility to the affected areas. This is particularly important for patients who have undergone amputation or have significant loss of function due to frostbite[2].
