Ice Burn First Aid: Treating Blisters and Frostbite from Direct Ice Application

Direct ice-to-skin contact causes thermal injury (frostbite) within minutes. Ice packs must always have a barrier (towel, cloth).

Immediate First Aid

1. Remove ice immediately.
2. Rewarm gradually: Lukewarm water (37–40°C / 98–104°F) for 15–30 min. Do NOT use hot water, radiators, or friction.
3. Protect: Sterile non-adherent dressing; elevate.
4. Pain control: Ibuprofen 400–600 mg q6h.
5. Do not pop blisters: Intact blisters are sterile barriers.

When to Seek Medical Care

• Blister >2 cm, hemorrhagic, or on face/hands/genitals/joints.
• Signs of infection: spreading erythema, purulence, fever.
• Numbness, color change (white, gray, black) → deep frostbite.
• Underlying neuropathy, vascular disease, immunosuppression.

Prevention

• Barrier: towel, gel pack sleeve, commercial ice wrap.
• Limit: 10–15 min on, 30–60 min off.
• Check skin every 5 min for pallor, numbness.
