Frostbite

Charlie , Joseph E and Ethan j

What not to do

- Do not rub or massage the frozen area. The tiny ice crystals in the tissues can cause more tissue damage

- Do not rewarm the frozen area with radiant heat (eg fire , exhaust pipes) because this can rewarm the area to quickly and cause further tissue damage

- Do not apply snow or cold water to the frozen area because this can cause further freezing and tissue damage

What not to do

What to Do

What to do

- Follow DRSABCD

- Move the patient to a warm, dry place. If the feet or legs are affected do not let the patient walk.

- Gently remove the patient's clothing and jewellery from the affected limb. Handle the frozen tissue very gently to prevent further tissue damage

-As soon as possible, put the whole affected limb in a bath of warm water between 40 to 42 degrees celsius, for 15 to 30 minutes. The aom is to minimise tissue loss. Lower water temperature will be less benefical to tissue survival; higher water temperatures can produce a burn wound and increase the injury.

-Keep adding warm water to maintain a constant tempreture. During rewarming, ask the patient to gently move the injured limb. Do not massage the effected area.

-Keep the limb warm. Do not allow the limb to be refrozen. Do not break any blisters that form.

-After rewarming, cover the injured area with a light, loose nonstick dressing, preferebly clean, dry, non fluffy material (eg plastic cling film).

-Check the patient for shock, and treat if neccesary
