First aid for a snakebite should be provided correctly and on time. In this case, the main thing is to avoid a number of erroneous actions that will not only not help the victim, but can also lead to serious complications. First aid for a snakebite should in no case include the application of a tourniquet, as this will interfere with blood circulation and increase the decay of tissues at the site of damage. As a result - additional poisoning by decay products and almost 100% chance of gangrene. In addition, you can not cauterize, cut and moisten the wound with potassium permanganate. Alcohol and food will also only worsen the situation. The use of substances containing acid, boiling oil and ash can cause ulcerative formations and subsequent gangrene.
Proper assistance with a snakebite is to immediately immobilize the victim as a whole or his injured limb. This is especially true for viper attacks. The venom of this snake spreads through the body through the lymphatic vessels, and any muscle movements will increase the speed of its spread. For the same reason, first aid for a viper bite should include the application of a tight bandage of fabric. In this case, the bandage should not interfere with blood flow, but to some extent slow down the spread of poison along the lymph. The optimal tension force of the fabric is when two fingers can be pushed under it. At the same time, in the process of increasing edema, it is necessary to gradually loosen the dressing.
When first aid is provided for a snakebite, the victim should be placed so that the head is below the level of the legs. Due to this, blood circulation in the brain will be maintained at an almost acceptable level, since part of the liquid will be destroyed due to the poison.
First aid for a snakebite should include a reduction in the amount of poisonous substance. For this, it is necessary immediately after immobilization to begin to remove the poison from the wound, squeezing and sucking it for at least 10-15 minutes. Using these procedures, you can reduce the amount of poison by almost half. The carer should not be afraid of poisoning if he does not have wounds and ulcers in the oral cavity, since only an insignificant dose of the poisonous substance can enter the blood through the oral mucosa. After such a first aid for a snakebite is provided, the wound needs to be washed. A person who removes poison needs to periodically spit saliva, and at the end of the procedure, rinse your mouth with water.
To reduce the concentration of the poisonous substance, a bitten snake needs to be given a plentiful drink. With a sharp deterioration in the condition of the victim away from medical institutions, he needs to inject an anti-inflammatory hormonal agent into the blood. When transporting a bitten person, ensure maximum immobility. The best option is to transfer the victim on a stretcher or on his hands, if it is a child. An affected arm or leg is best secured with a tire. We must not forget about the moral support of the victim, since many people perceive a snake bite as certain death. In addition, he may begin to have visions, hallucinations, depression. It is necessary to convince a bitten person that not everything is so scary.
