Frost Bite and Hypothermia

hypowrapWell, It snowed here in Oregon today.  The first real snow fall of the “Winter”.  And as much as we have already prepared for our winter camping experiences, the snow reminded me of the risk we accept when winter camping and more to the point the risk that we mitigate or manage through proper training and preparation.  First Aid is perhaps the most training we do to prepare for winter outings and we make sure that everyone going on the outing is versed in being prepared for cold weather injuries.
The scariest thing that I can think of in training first aid is Frost Bite and Hypothermia.  They can strike fast and have tremendous damaging effects if not prevented and once affected, treated.
As the snow fell today, I thought it would be good to refresh ourselves on those two cold weather injuries.
Frostbite mostly affects areas where the circulation is poor. Since cold weather will cause the body to take preventive measures by constricting (making smaller) the blood vessel, this opens the door to frostbite injuries.

Look for the 4 Ps of frostbite:
Pink – affected areas will be reddish in color. This is the first sign of frostbite.
Pain – affected areas will become painful.
Patches – white, waxy feeling patches show up – skin is dying.
Pricklies – the areas will then feel numb.

Tips to prevent frostbite:
Get to a warm area before frostbite sets in.  If it’s too cold outside, consider staying indoors.
Protect areas of poor circulation (ears, nose, fingers and toes).
Keep extra mittens and gloves in an area quickly accessible.
Wear larger sized mittens over your gloves.
Wear a scarf or gaiter to protect the chin, lips and cheeks. They are all extremely susceptible to frostbite.
Wear two pairs of socks – wool if possible
Keep feet warm and dry
Remove any wet clothing.

What to do in case of frostbite:
Do not rub or massage affected areas.  It may cause more damage.
NOT HOT – warm up the area slowly. Use warm compresses or your own body heat to re-warm the area. Underarms are a good place.
If toes or feet are frostbitten, try not to walk on them.
Seek immediate medical attention if you see white or grey colored patches or if the re-warmed area is numb.
Always be on the lookout for the symptoms of frostbite.  In case of serious cold weather injury, seek immediate medical attention.

Hypothermia
Whenever the body’s normal temperature becomes too low, hypothermia (hypo = low and thermia = temperature) occurs and will starve the brain of much-needed oxygen.  We experience hypothermia conditions when we engage in strenuous activity like hiking into camp, getting sweaty and then standing idle allowing the body to cool to fast.  During cold weather months, finding warmth can be the key to survival, but hypothermia can occur even during the hot days of July.  Swimming in cold water for a long period of time can induce hypothermia even in the hottest months of the year.  Remember, hypothermia can quickly become life-threatening.

Signs of Hypothermia
Look for the “UMBLES” from people affected by cold temperatures:
A person who mumbles;
A person who stumbles; and
A person who fumbles objects.

Tips to prevent Hypothermia
Wear clothes in layers: The under layer should be the insulating layer to prevent loss of your body heat while keeping the cold outside air away; the outer layer should be the “wind breaking” layer to reduce the chances of cold air reaching the insulating layer.
Drink warm fluids.
If you start to sweat, cool off a little. Wet clothes will accelerate other cold weather injuries.
Wear a hat – up to 40% of body heat loss can occur through the head.
Wear gloves or mittens or both!
Wear a scarf or gaiter to protect the chin, lips and cheeks – all are extremely susceptible to cold weather injuries.

What to do in case of Hypothermia
Remove wet clothing that promotes hypothermia.
Get to a warm place as soon as possible. Use several layers of blankets or sleeping bags, heated if possible.  Place the injured person in the Hypothermia Wrap.
If the person is alert, give warm beverages.
Seek immediate medical attention.
Always be on the lookout for signs of frostbite and hypothermia.  In case of serious cold weather injury, seek immediate medical attention.  Here is a quick video from Wilderness Medical Associates (WMA) that illustrates the Hypothermia Wrap.

BE PREPARED! We use the buddy system to watch out for each other! These two injuries are serious and can hurt you in the long-term.  Camping in the winter can be the funnest time of your Scouting life! But you have got to be prepared!

Hope that helps you in your preparation for your next winter outing.  I am glad that our guys pay attention, in 10 years of winter camping we have never had a cold weather injury.
Have a Great Scouting Day!
