Snakes are common in many parts of the world. While most snakes are not dangerous to humans and will not attack unprovoked, some species like vipers can be aggressive and their bites carry toxins that affect the body. Symptoms of a snake bite include effects on neural structures, blood cells, the heart and blood vessels, and neuromuscular transmission due to components in the venom. Immediate first aid following a bite includes keeping the victim still and horizontal, sucking out venom if possible, applying a bandage, and providing CPR if shock develops.

2. What is the Serpent Sting
Snakes ubiquitous, so wherever there was a
man, he may be subjected to attack. Especially
dangerous are a poisonous snake. In Russia
and neighboring countries and the most
common viper snakes. It is worth noting that
snakes are not dangerous for humans.
Moreover, they never attack first. Snake attack
can undergo only if deliberately to annoy him.
Quite different is the case with other
types of vipers and poisonous snakes.
They initially aggressive. Better to get
around their party as to provoke an
attack is enough presence of human or
animal.

3. The symptoms of
snake bite
• The clinical manifestations of snake bites, regardless
of their type, are characterized by certain common
features. This is due to the presence of components of
snake venom.
• 1. Neurotoxin - affects neural structures;
• 2. Hemolysin - causes disintegration of red blood
cells and other blood cells;
• 3. Cardio toxins - has a toxic effect on the heart and
blood vessels;
• 4. Cholinesterase - an enzyme that violates
neuromuscular transmission;
In addition to these toxins venom contains many other
components, which have a destructive effect on tissue.

4. First aid for the bite of a snake / viper
1. Reassure the victim and put in a horizontal position. This slows down the blood flow and
the spread of venom.
2. No pain, swelling and any local or general manifestations is an indication of non-poisonous
snake bite;
3. If you clearly know that the poisonous snake - action begin without delay;
4. Suction of venom from the wound surfaces. Ideally it should be made by means of a
suction or blower. But in their absence resorted to suctioning mouth, if there is no obvious
damage to the mucous membrane;
5. If necessary, a better suction can make small linear incision wounds from the bite;
6. Overlay compressive bandage above the bite area. This overlaps only partially lymphatic
drainage and venous. The arteries to function that will prevent severe disorders of
microcirculation and necrotic changes;
7. With the development of lightning and toxic shock reaction shown resuscitation to restore
airway and chest compressions.
