Is there anything wrong with being bitten by bamboo leaf green?
Many people will tell you: Bamboo leaf green is a slightly venomous snake, and it is okay to be bitten. They will even give examples of many people who are okay after being bitten to prove that what they say is true. Is that really the case?
According to news reports, on the evening of May 18, 2022, a man was traveling in Sanya when he was bitten by Bamboo Leaf Qing. He immediately contacted the head of the hotel.
The person in charge of the hotel immediately contacted the police, and the police found 3 hospitals in a row through relay medical treatment, and finally sent the man to the hospital with serum, which took less than half an hour before and after. Although it has been sent to the hospital as quickly as possible and injected with serum. However, the man's arm was still bleeding, even swollen like a bun, and the man said in an interview:
After arriving at the hospital 20, 30 minutes, the whole person is not OK. In the end, I played for 5 hours and felt like I had come back to life.
Therefore, if you are bitten by a bamboo leaf green snake and do not treat it in time, it is easy to explain yourself if you don't do well. So the question is, why do so many people think that Bamboo Leaf Qing is a micro-venomous snake, or even a non-venomous snake?
In fact, let's think about this question carefully: can you understand the cases of those who have major problems or even die because they are bitten by bamboo leaf green? Or will they still say it?
Yes, in fact, there is a typical survivor bias about being bitten by a bamboo leaf green snake. We often hear some cases of bamboo leaf green and slightly poisonous, poison does not cause death.
For example, a 64-year-old aunt in Quanzhou, Fujian Province, was suddenly bitten by Bamboo Leaf Qing when she was changing shoes at the door. Because the first bite did not see what kind of snake it was, mistakenly thought it was a centipede, but unexpectedly in the process of throwing away the poisonous snake was bitten twice, it was found that it was a poisonous snake ZhuYeqing.
If she was bitten twice in a row, if it was replaced by another poisonous snake, she may not have been sent to the doctor, and the situation was already very critical, but this aunt did not seem to have symptoms so severe, and after injecting antivenom, the situation has improved.
These cases can easily make us think that the snake venom of bamboo leaf green is not so strong, and even if it is bitten, the survival rate is still high.
But in fact, the people who can tell you these cases are those who are not seriously injured, or when the bamboo leaf green bites people, the injection of venom is minimal, only part of the case, not all.
What we do know is that if we collect enough data to see it, it is possible to get results that are more truth-oriented.
According to the results of many studies, bamboo leaf green is the number of injuries in our country that can rank in the top three. This is mainly due to its wide distribution range, which is distributed in Anhui, Fujian, Gansu, Guangdong, Guangxi, Guizhou, Hainan, Hubei, Jiangsu, Jiangxi, Sichuan, Yunnan, Zhejiang, Hunan Xiangxi, Taiwan and other places on the mainland.
According to data from the Snake Injury Center of Shenzhen Hospital of Traditional Chinese Medicine, the total number of patients with bamboo leaf green snake injuries they treated from 2013 to 2017 totaled 593.
You should know that this is only the data of the Snake Injury Center of Shenzhen Hospital of Traditional Chinese Medicine, if you look at the whole country, this data will be very scary. In so many bites, there are some minor injuries, which are also normal, and we cannot conclude that Bamboo Leaf Qing is a slightly venomous snake based on a single case or a few minor injuries.
Bamboo leaf green is one of the ten most venomous snakes in the mainland, belonging to the chordate phylum - reptiles - scaly - viper family - bamboo leaf green snake genus. You know, there is no good stubble in the viper family, it is a poisonous snake distributed all over the world.
In the genus Bamboo Leaf Green Snake, there are more than thirty species. In the mainland, the bamboo leaf green snake that hurts the most people is called: Fujian bamboo leaf green, scientific name: red tail green bamboo silk.
Most of the bamboo leaf green snakes that often appear on the news to bite people are Fujian bamboo leaf green. Many people say that bamboo leaf green belongs to the slightly venomous snake, this is because fujian bamboo leaf green bites people, often has mild symptoms.
The main reason is actually that the amount of venom in Fujian Bamboo Leaf Qing is too low, and it is actually meaningless to talk about toxicity without dose. However, in fact, a considerable proportion of people have been seriously injured by the bite of Fujian bamboo leaf green, and there are many cases of DIC (disseminated intravascular coagulation). In addition to Fujian bamboo leaf green, there is also a kind of bamboo leaf green snake in China that has many injury cases, that is: white-lipped bamboo leaf green.
Here to add, the case of white-lipped bamboo leaf green injury is slightly less than that of Fujian bamboo leaf green, but the toxicity of white-lipped bamboo leaf green is actually stronger than that of Fujian bamboo leaf green, and it is easier to cause DIC, and the average fatality rate is much higher than that of Fujian bamboo leaf green. Of course, it should be mentioned here that there are regional differences in the toxicity of white-lipped bamboo leaf green.
The venom released by the bamboo leaf green bite is mainly a mixture of venom based on blood circulation, and its main harm is to destroy the coagulation system of the bitten person, causing mild coagulation dysfunction, and a certain proportion will cause DIC, cerebral infarction cerebral infarction and toxic shock
Onset of symptoms.
After being bitten, light subcutaneous bleeding, nosebleeds, bleeding gums, severe cases can cause blood decoagulation, bleeding from the wound, hematuria, gastrointestinal bleeding, and even cerebral hemorrhage.
LD50 is half the lethal amount, and the smaller the value, the more toxic it is. The subcutaneous injection of LD50 = 3.3 mg/Kg in Fujian Zhuyeqing is about 3 times that of the five-step snake (the value of LD50 injected under the injection is 9.2 mg/kg). However, the average detoxification amount of 5.1mg, is really relatively small, if we also take the five-step snake to compare, the average detoxification amount is about 214 mg, the maximum can reach 400 mg, so it seems that the five-step snake bites people far more serious than bamboo leaf green.
The white-lipped bamboo leaf green, the vein LD50 = 0.5mg / kg, equivalent to 20 times the five-step snake, the average detoxification amount of about 28mg.
According to a paper entitled "Epidemiology and Treatment of Emergency Snake Injuries in Guangxi", the authors collected 257 cases of emergency snake injuries from the First Affiliated Hospital of Guangxi Medical University from 2006 to 2009, of which 55 cases were bitten by bamboo leaf green, ranking second.
Of these cases of being bitten by bamboo leaf green, there were 30 mild cases, 16 severe cases and 9 critical cases. So, see?
It is not that after being bitten by bamboo leaf green, it will be fine, at least half of the snake wound patients are severe and critical, if not treated in time, there may be a danger to life.
In an article entitled "Clinical Characteristics and Therapeutic Effect Analysis of 146 Cases of Bamboo Leaf Green Snake Bite Poisoning", the authors collected the clinical data of 146 cases of bamboo leaf green snake bite poisoning admitted to the Emergency Department of the First Affiliated Hospital of Guangxi Medical University from January 2009 to October 2014.
Among them, the proportion of patients with skin and soft tissue necrosis reached 44.9%, coagulation dysfunction accounted for 34.9%, liver and kidney dysfunction accounted for 11%, multi-organ dysfunction accounted for 5.5%, and there were 2 deaths, accounting for 1.4%.
According to some statistics, the average fatality rate of Fujian bamboo leaf green is 1.14%, while the average fatality rate of white-lipped bamboo leaf green has reached 18.87%.
That is to say, if you are bitten by bamboo leaf green, there will not only be severe illness, but even death. From these points of view, if you encounter Bamboo Leaf Qing, or as far away as possible, and can not be close to or even play with Bamboo Leaf Green because you hear others say that it is a slightly venomous snake, after all, you can't determine how much venom Bamboo Leaf Qing injected into you when you were bitten to death, if this time it is just very much, it is not a tragedy?
