The methods of self-help are as follows:
1. Ligature. Tie the top of the wound with a tourniquet or cloth, etc.. Its degree of tightness to be able to prevent venous blood and lymphatic fluid back to prevail. After the snake venom, in order not to expand the area of poisoning, we must tie the injured limb tightly to prevent blood flow caused by a larger area of poisoning. If you are traveling in the countryside, there is no tourniquet, you can tear off a piece of cloth from your shirt to tie. The ligature should not be too tight, as it can easily lead to necrosis of the organism. Every 20 minutes after ligation, loosen it for 1-2 minutes and tie it again. In this way, not only can ensure the blood supply of the injured limb, but also can make the venous blood and lymphatic fluid return. After the ligation should be sent to the hospital as soon as possible.
2, in the field rescue conditions are very difficult, to use a match to cauterize the wound, destroy the snake venom, and then ligature, and find ways to send to the hospital rescue.
3. If you are close to home, or there are people nearby, find a way to flush the wound immediately with cold boiled water, soapy water, but do not use well water or river water to flush, so as not to infect the wound.
4, if the critical moment around the fire and knife, you can expand the wound detoxification. Put the knife on the fire to burn, disinfection, and then cut the skin longitudinally according to the direction of the fang marks, it is best to connect the two fang marks. This will encourage the lymphatic fluid to flow out and the venom to be eliminated. However, do not cut too y so as not to injure the limb. Some teenagers find this too painful to bear. However, in the critical moment of snake venom, this is necessary. There is a principle in self-protection and self-rescue awareness, which is to choose the lesser of two evils. That is to say, in the event of danger, disaster, to be willing to give up some, in order to get some. For example, if a driver is driving on a steep slope and suddenly realizes that his car's brake is not working, he can intentionally crash his car into a tree on the side of the road, preferring to destroy both the car and the tree, rather than letting the car go down the steep slope and destroying the car and the people. The same is true for the snake venom, which is a skin and muscle injury, but also to save the life of the snake.
In addition, in the absence of the above conditions, you can also use the mouth to take drugs. But the sucker has to be free of dental caries, no breaks or ulcers in the mouth to be able to do so. After sucking to spit out as soon as possible, and rinse the mouth. If there is a wound in the mouth, you can't use drugs to prevent yourself from being infected by snake venom.
5, as a poisoned person, must be quiet, do not struggle indiscriminately, running, to bed, limit limb activity.
In the event of a dangerous situation, the rescuer must also learn to improvise and act opportunistically. Especially in the field and home is different, home may have a first aid kit, supplies are available, but also can call the emergency vehicle. But the vast field may not even a shadow of a person, not to mention the readily available first aid supplies. In this case, try to find alternatives.
It's also important to prevent snakebites, just in case. In places where snakes are expected to be present, you can hold a long pole or stick, and knock on the weeds before walking, and then land on your feet, and you generally won't be bitten by a snake.
Nature is certainly very beautiful and attractive, but it is still important to be careful and put self-protection first.
