When journeying
into the wilderness it is important to carry a complete first aid kit and book.
It is also wise to take a first aid course. A good diet, cleanliness and appropriate
clothing will lower the risk of harmful situations.
Disease, infection and often, insect bites can be avoided when maintaining
a proper diet. It is important to bathe daily but if this is not possible be sure
to wash your hands frequently. Soap can be made using ashes and animal fat or
by boiling the inner bark of a pine tree. Construct a toothbrush by mashing the
end of a green twig. When setting out for your journey remember to pack a wide
range of clothing and extra footwear.
FIRST AID
If an accident occurs in the wilderness it will be your responsibility to deal
with the situation. The specific sequence of actions when dealing with this situation
is:
1. Remain calm, providing your patient with quiet, efficient first aid
treatment.
2. Keep the patient warm and lying down. Do not move this injured person
until you have discovered the extent of the injuries.
3. Start mouth-to-mouth artificial respiration immediately if
the injured person is not breathing.
4. Stop any bleeding.
5. Give your patient reassurance. Watch carefully for signs of shock.
6. Check for cuts, fractures, breaks and injuries
to the head, neck or spine.
7. Do not allow people to crowd the injured person.
8. Do not remove clothing unless it is imperative.
9. Decide if your patient can be moved to a proper medical facility. If
this is not possible, prepare a suitable living area in which shelter, heat and
food are provided.
SHOCK
Shock is a depression of all of the body processes and
may follow any injury regardless of how minor. Factors such as hemorrhage, cold
and pain will intensify shock. When experiencing shock the patient will feel weak
and may faint. The skin becomes cold and clammy and the pulse, weak and rapid.
Shock can be more serious than the injury itself.
Use the following method to prevent and control shock:
1. When treating injuries:
i. restore breathing
ii. stop bleeding
iii. treat breaks and fractures
2. If there are no head or chest injuries place the patient on his/her
back with the head and chest lower than the legs. This will help the blood circulate
to the brain, heart, lungs and other major organs.
3. If severe head and chest injuries are present elevate the upper body.
If chest injuries are present, elevate the injured side to assist in the functioning
of the uninjured lung.
4. If the injured person becomes unconscious, place him/her in a face down
position to prevent choking on blood, vomit or the tongue.
5. Keep your patient warm and under shelter.
STOPPED BREATHING
If breathing has stopped, begin mouth-to-mouth resuscitation.
Place the patient on his/her back and follow these steps:
1. To open the airway lift the patient's neck and tilt the head back.
2. Keeping the neck elevated, pinch the nostrils to prevent air leakage.
3. Place your mouth completely around the victim's mouth and blow, watching
for chest expansion.
4. After removing your mouth, listen for air leaving the patient's lungs
and watch for the chest to fall. Check for an airway blockage if the chest does
not rise.
Repeat these steps approximately 12 to 15 times per minute. If treating a child,
cover the nose and mouth with you mouth. Use smaller puffs of air and repeat this
method 20 to 25 times per minute.
BLEEDING
To control bleeding, elevate the wounded area above
the heart and apply pressure using either gauze, clean cloth, dried seaweed or
sphagnum moss. Use pressure at the pulse point between the injured area and the
heart if bleeding fails to stop. If bleeding still persists, use a tourniquet
between the injury and the heart. This method should only be used in extreme situations.
After bleeding has been controlled, wash the wounded area with disinfectant and
apply a dressing and bandages.
FRACTURES
A fracture is classified as either a simple (closed)
or compound (open). Signs that a fracture is present include:
1. Pain at the affected area.
2. The area may or may not be deformed.
3. The victim is unable to place weight on the area without experiencing
pain.
4. A grating sensation or sound may be present during any motion of the
injured area.
Treatment is as follows:
1. If in doubt, treat the injury as a fracture.
2. Splint the joints above and below
the fracture.
3. If the fracture may penetrate the skin, it could be necessary to apply
traction to straighten the deformity.
4. Be sure to pad your splints.
5. Check the splint ties frequently to be sure they do not hinder circulation.
6. Cover all open wound with a clean dressing before splinting.
DISLOCATION
Dislocation happens when the ligaments near a joint
tear, allowing the movement of the bone from its socket. It is unwise to treat
a dislocation unless you are a trained professional as permanent damage may occur.
The affected extremity should be supported using a sling or other device and pain
controlled with aspirin or other suitable drugs.
SPRAINS
Treat sprains by applying cold to the area for the first
24 hours then once the swelling has subsided, let the sprain sit for a day. Apply
heat the following day to aid in the healing process. The sprain should be splinted
and rendered immobile until the pain has completely disappeared.
CONCUSSIONS
Concussions or other head injuries are often accompanied
by a leakage of watery blood from the nose or ears. Other symptoms may include
convulsions, an unresponsiveness of the pupils or headache and vomiting. Keep
the injured party warm, dispense a pain killer regularly and allow time for the
body to rest and repair.
HEAT EXHAUSTION
Heat exhaustion is not uncommon when water is not sufficient.
The body becomes dehydrated and salt-depleted, resulting in nausea, faintness,
a weak, rapid pulse and/or cold and clammy skin. Treatment includes plenty of
rest, liquid and salt tablets.
SUNSTROKE
Sunstroke may occur when the body is exposed to excessive
sun. The body becomes overheated and provides too much blood to the circulatory
system resulting in a flushed, hot face, rapid pulse, headache and/or dizziness.
Treat sunstroke by resting in a cool area and applying and consuming cold liquid.
Prevent sunstroke by wearing proper headgear.
MUSCLE CRAMPS
Muscle cramps occur when the muscle accumulates excessive
lactid acid or a loss of salt through perspiration. Treatment includes resting,
deep breathing and stretching.
BURNS
Burns are most commonly followed by shock. Administer a
pain reliever immediately, apply sterile, dry gauze to the affected area
and bandage. The patient should consume more water than usual.
SNOWBLINDNESS
Symptoms of snowblindness include scratchy or burning
eyes, excessive tearing, sensitivity to light, headache, halos around light and
temporary loss of vision. Bandage the victim's eyes and use cold compresses and
a painkiller to control the pain. Vision will generally be restored after 18 hours
without the help of a doctor. Always wear snow goggles or sunglasses in snowy
areas to prevent snowblindness.
FROSTBITE
Frostbite occurs when the tissue of an area, most commonly
the toes, fingers or face, is frozen either from direct exposure to the elements
or high wind. First degree frostbite turns the area cold, white and numb. When
heated the area becomes red and can be compared to a first degree burn. A blister
will form after warming with second degree frostbite. Dark skin, gangrene, and
a loss of some skin and tissues is common in third degree. Fourth degree frostbite
causes irreparable damage. The affected area will remain cold and lifeless and
generally a part of the area is lost. With adequate clothing frostbite can easily
be avoided. Superficial frostbite may be treated by cupping one's hands and blowing
on the affected area, warming from another warm hand or, with fingers, placing
them in your armpits. For more severe cases, medical aid should be sought.
BLISTERS
Blisters are the painful, and common, result of ill-fitting
footwear. At the first sign of discomfort, remove boots and socks and place a
piece of adhesive tape over the affected area. Apply disinfectant and a bandage.
HEADACHES
Headaches are often experienced in the mountains due
to inadequate eye protection, tension in the neck, constipation or "water
intoxication", a swelling of the brain tissue which happens when the hiker
has sweated excessively over a period of days and consumed large quantities of
water without enough salt in the body. Aspirin may be used to alleviate the pain but
one should find the source of headache to prevent further discomfort.
SNAKE BITES
See the SNAKEBITE EMERGENCY FIRST-AID INFORMATION section.
BEE STINGS
Bee stings are common and harmless unless you are allergic.
Remove the stinger then apply disinfectant and clod water to reduce the swelling.
A change of diet, dirty cooking utensils or the consumption of tainted water
may result in diarrhea which in turn will cause a loss of nutrients and precious
body fluids. Take extra care in cleanliness and boil water for an additional three
to five minutes to avoid diarrhea.
HYPOTHERMIA
When the temperature of your body falls to a level at which your vital organs
can no longer function you are experiencing hypothermia or exposure sickness.
Hypothermia will develop rapidly and is caused by cold, wet and/or windy weather
that chills the body at a speed faster than it can produce heat. A lack of energy-producing
food and proper clothing will heighten the speed at which hypothermia will affect
you. Always remember to bring extra clothing. It is important to hike at the speed
of the slowest member of your party. Take frequent breaks and keep a close watch
for members experiencing signs of fatigue. Exposure sickness generally occurs
in temperatures of less than 10 C (50 F).
Symptoms are easily recognizable:
1. Feeling cold and constantly exercising to keep warm.
2. Uncontrollable shivering and numbness.
3. Violent shivers. Your mind becomes slow and starts to wander.
4. Violent shivering ceases and muscles begin to stiffen and become un-coordinated.
Exposed skin becomes blue and thoughts are foggy. Victim usually lacks the capability
of realizing how serious the situation is.
5. Pulse and respiration slows.
6. Victim will not respond and becomes unconscious.
7. The section of the brain controlling the heart and lungs ceases functioning.
Treatment must be quick and efficient:
1. Move the victim to a sheltered area, out of the elements.
2. Remove wet clothing and replace with dry clothes and if possible, a
sleeping bag.
3. Wrap warm rocks and place them near the patient.
4. Do not let the victim fall unconscious.
5. Give the victim a warm, non-alcoholic drink.
6. Allow another person in the sleeping bag to share body heat.
7. Exhale warm air near the vicinity of the patients mouth and nose.
HYPERTHERMIA
Hyperthermia is a result of the body being overheated due to increased air
temperature, solar or reflected radiation, poorly ventilated clothing, a low fitness
level or excess bulk.
Symptoms include:
1. Heat cramps may occur and should be treated by moving the victim
to a shady area and supplying water and salt tablets.
2. Heat exhaustion is a mild form of hyperthermia and includes symptoms
such as headache, dizziness, fainting, clammy skin, blurred vision, nausea and
vomiting. Treatment is the same as heat cramps.
3. Heat stroke is the most serious degree of hyperthermia. The victim will
have little or no perspiration, a hot and flushed face, full pulse, and become
either apathetic or aggressive. Cool the victim as quickly as possible paying
extra attention to the head, neck and chest. If the bodies temperature continues
to rise, unconsciousness, delirium, convulsions and ultimately death may occur.
To avoid hyperthermia, avoid strenuous activity on hot days, wear loose clothing
and a hat, drink plenty of fluids and take salt tablets.
