What if I get bitten by a cobra?

Cobra is a general term for animals of the genus Cobra. It often likes to live in bushes or bamboo forests in plains, hills, mountains, mountains, streams and fish ponds, fields, and houses. It is highly poisonous. If it angers people, it is one of the main venomous snakes in our country. Let's take a look at what to do if we are bitten by a cobra.

Bite diagnosis of Cobra

The bite marks are wider and less bleeding, and the pain is obvious, but there is a sense of numbness in the center of the wound, the center of the wound is quickly purple, but the surrounding area is red and swollen, the pupils of the heavy ones are reduced, and tissue necrosis and ulcers are easy to occur.

Toxicological effects of Cobra

1. Toxicity to the nervous system: Naja naja atra venom is a mixed poison dominated by nerve poison to people or animals, and its effect on the nervous system is extensive and complex, and there is often a bi-directional effect, that is, due to different doses, or individual differences in animals, or differences in nervous system sensitivity to show excitement or inhibition.

2. Toxicity to the circulatory system: although respiratory paralysis is the first cause of death caused by venomous snakebites of the cobra family, most patients with mild poisoning or respiratory inhibition have shown myocardial damage and electrocardiographic changes of myocarditis, and patients with severe cobra bite poisoning have experienced severe shock even before respiratory inhibition. Therefore, the toxicity to the circulatory system is also an important factor of poisoning and death, which can not be ignored.

3. The role of enzymes in snake venom: snake venom itself contains many enzymes, which can have a serious toxic effect on the body.

The bite symptoms of a cobra

1. Early symptoms: immediately after the cobra bite, the pain worsened gradually, and numbness appeared in the center of the wound for about 10 minutes. The wound did not bleed much, it soon closed and blackened, and the surrounding skin quickly became red and swollen. There are often local blisters, blood blisters and ecchymosis, accompanied by lymphadenitis, prone to tissue necrosis and ulcers.

2. Late symptoms: drowsiness, dizziness, giddiness, chest tightness, palpitation, vomiting, abdominal pain, chills, fever, muscle weakness, dysphagia, stiff neck, dumb voice, stumbling gait may occur 2-6 hours after cobra bite. Severe patients with closed teeth, dyspnea, pupil narrowing, and finally shock, often have convulsions before death.

What if I get bitten by a cobra?

The general treatment for cobra bites is to use antivenom and may require artificial ventilation (such as endotracheal intubation) until the venom is degraded and the patient can breathe on his own. If the ineffective treatment of patients is more than 6-12 hours after the bite, the cause of death is mostly asphyxiation due to respiratory paralysis (such as diaphragmatic paralysis).
