Premergency First Aid, CPR and AED Manual

9 Other Emergencies

• Immerse the affected part. Add warm water as needed to keep the temperature constant. • Keep the part immersed until colour returns to normal or no longer improves; this may take 45 minutes. For severe frost-bite re-warm within 24 hours. • The thawing of a frozen part is usually very painful. Reassure the patient frequently and provide what comfort you are able. • Gently pat the skin dry. Dress any wounds or blisters. If fingers or toes are affected, lightly pad between the digits with dressings. • Keep wounded part elevated, warm, and dry. • Provide ongoing care. Get medical help as soon as possible. Do not disturb the formation of blisters. If blisters develop, cover them with a dressing and bandage lightly.

If you are unable to get medical help and there is access to a safe and warm place and there is no chance of the frostbitten part refreezing: • Place the patient in a position of comfort. • Remember, once thawed, the injured part must be kept at rest and not used. If the patient needs to walk as a means of reaching medical help, then do not thaw a frostbite injury to the leg, foot, or toes. Less pain and additional injury will occur if the part remains frozen. • Gently remove jewelry and clothing from the affected part. • If available, fill a container big enough to completely immerse the affected body part in lukewarm (approximately 37° C-40° C) water for 20-30 minutes.
