For the American man Jeremy, if he could turn back the clock, he would no longer rush to reach out and pick up the decapitated snake's head, after which he wandered on the edge of life and death several times, and the doctor injected him with anti-venom 26 times in a short period of time, and finally took his life back at the hands of the god of death.
Three years ago to May 30, Jeremy, a Texas man in the United States, was attacked by a rattlesnake that had been dead for a long time, resulting in a severe erosion of venom, and even the attending doctor at the time was not sure whether Jeremy would survive.
Jeremy and his wife Jennifer have been living in South Texas, and they have been busy tending the lawn in the garden to welcome their daughter and granddaughter who are about to return home.
In the local area, there is a frightening animal, the western diamond-spotted rattlesnake. Unfortunately, while mowing the lawn, Jennifer encountered a 1.3-meter-long rattlesnake, which quickly raised its head and rustled its tail behind her.
The rattlesnake may attack Jennifer at any time, and in order to protect his wife, Jeremy directly slaps the snake with a shovel and decapitates the snake's head.
In this case, the average person's practice is to wait for the snake to completely die, and bury the snake's head deep with a shovel, but Jeremy did not do this, which also laid the groundwork for the tragedy that followed.
For ordinary animals, if the head is cut off, it means the end of life, but the snake is a maverick existence. Jeremy didn't expect that ten minutes had passed, and the snakehead was still aggressive.
After the two men finished taking care of the garden, Jeremy thought that the snake was dead, and without protection, he directly reached out to pick up the snake's head, but when the hand touched the snake's head, the snake head actually opened its mouth and bit jelly on Jeremy's hand, and after hearing her husband's cry for help, Jennifer rushed to her husband's side and helped him drag the snake's head down together.
Jennifer, a nurse before retiring, was in danger and quickly called to inquire whether the nearby hospital had antivenom in stock.
Knowing that the nearest hospital was also a few tens of minutes by car, she directly picked up her husband and drove there, but after only two kilometers of driving, Jeremy fell into a coma.
Eventually, through the coordination of the relevant authorities, Jeremy was taken by helicopter to the nearest hospital for treatment.
After the examination, the doctor found that Jeremy had developed sepsis shock, blood pressure began to drop rapidly, bleeding inside the body began to bleed, and various organs began to fail, and could only be used to maintain life with a ventilator.
In just one day, the hospital issued three critical notices, but Jeremy survived with frequent injections of antivenom, excellent physical fitness and strong will, during which he was injected with a total of 26 antivenoms, and the average patient who was bitten by a snake could be detoxified by about four injections.
Seven years ago, a chef in Foshan, Guangdong Province, cut off the head of a black-necked cobra and placed it next to the board, and 20 minutes later, the chef was accidentally bitten by the snake's head, resulting in the death of the chef.
Scientists have also analyzed that snakes belong to reptiles of cold-blooded animals, and the metabolism rate of snakes is much slower than that of thermostatic animals, which means that if the head is decapitated, the snake's autonomous activity time is much longer than that of the thermostatic mammals, so beware of snakes, even if it is decapitated, it is still extremely dangerous.
After investigation, scientists found that the snake could still maintain its conditioned reflexes for several hours after death. For venomous snakes, their main reflex is to bite their prey and inject venom.
Jayn, a biology professor at the University of Cincinnati in the United States, believes that since people subjectively believe that snakes have been dead for a while, in fact, their bodies can still maintain activity, which is very similar to the situation where the head of the chicken is cut off when killing the chicken, and the headless chicken struggles and dances around.
The principle is that the decapitated snake does not need the brain to send command signals at all, and the preset nervous system can make certain fixed movements, and the decapitated snake will bite and inject venom when stimulated by the outside world.
According to statistics, about 11,000 people in the United States are bitten by snakes every year, of which about 5 to 8 people die from snake venom. Jayne believes that the vast majority of people who are bitten by snakes are caused by misconceptions.
Snakes are a very shy animal, they generally rarely take the initiative to attack humans, human size is large, so it is not the food of snakes, snakes encounter people, try to avoid.
Only when humans attack, trample or disturb snakes will they enter a state of attack, defending with precious venom.
If you encounter a snake in the wild, try not to disturb, avoid, and do not panic and run away or actively provoke or attack the snake.
Snakes are very important throughout the ecosystem, and if all snakes disappear, they will definitely affect humans. Rats often steal grain from farmers and have a large number of ticks parasitic on their bodies, and the main food of snakes is rodents such as rats. So when the snake is eating, it inadvertently protects the crops and eliminates a large number of ticks.
In the western United States, a single rattlesnake can kill about 4,500 ticks and nearly a thousand rats a year, not only protecting crops, but also indirectly helping humans reduce various deadly infectious diseases caused by tick bites. For example: Lyme disease, forest encephalitis, etc.
In addition, if you are bitten by a poisonous snake, you must be as calm and calm as Jennifer, go to the hospital in time, inject antivenom, and race against the clock to bring hope to life.
Don't learn the method of sucking snake venom in the TV series, if there is a wound in the digestive tract or mouth, it is likely to be poisoned together.
