What are the symptoms of being bitten by a cobra

In modern life, people live in harmony with all kinds of creatures and live in the same environment. However, some creatures can bring troubles to people's lives. For example, snake, rat and insect pests are extremely difficult to avoid. Especially venomous snakes cause a large number of casualties every year, and venomous snakes are one of the culprits. Among them, cobras are extremely threatening venomous snakes. What are the symptoms of being bitten by a cobra?

First of all, there is obvious pain when being bitten by a cobra at first, but the pain will subside after a while. This is because the neurotoxin has a paralyzing effect, which is often easily ignored by patients and leads to serious consequences without timely treatment.

When bitten by a cobra, the wound will be painful at first, but after about ten minutes, there will be a noticeable numbness, accompanied by symptoms of chills and fever all over the body.

If anti-snake venom drugs are not taken promptly and effectively, the patient will experience dizziness, blurred vision, vomiting, drooling, chest tightness, and difficulty breathing within 1-2 hours. Severe patients may also experience difficulty speaking, peripheral respiratory paralysis, limb weakness or whole body paralysis, etc. But the patient is very conscious at this time. If rescue is not timely, the patient will die of respiratory failure, circulatory failure and renal failure, and will suffer from incontinence before death.

After a cobra bite, we will see two tooth marks on the wound. Some bites are special and may have 1-4 tooth marks. This is because some bites are caused by only one fang or multiple bites. Observing the patient with the bite, it can be found that there is obvious swelling around the tooth marks and on the patient, as well as ecchymosis, blisters and blood blisters, tissue necrosis and ulcers. There is lymphangitis and lymphadenopathy in the affected limb. The body temperature rises, the blood also rises in the early stage, and the heart rate accelerates. When respiratory paralysis occurs, after being bitten by a cobra, there will be cyanosis and other hypoxic conditions. If rescue is not timely, circulatory failure will occur along with respiratory failure. At the same time, the eyes may be fixed, the pupils may be dilated, the whole body may be paralyzed, and the firing of various nerves may be weakened or disappear. When the whole body paralysis disappears. Local ulcers are often left behind or abnormal healing occurs.

When patients undergo blood tests after being bitten by a cobra, elevated white blood cells and alanine aminotransferase will be found. Hematuria examination showed symptoms such as hematuria, proteinuria and tubular urine. Electrocardiogram features include changes such as myocardial damage. These are the diagnostic criteria for cobra bites, especially when no snake is found. These data are important for determining what kind of venomous snake bite it is.
