Why is paraquat incurable once drunk?

A 13-year-old boy in Henan Province drank half a bottle of paraquat in a fit of rage. However, after drinking paraquat, she was taken to the hospital, but four days later her lungs had changed dramatically. Many netizens expressed their wonder why paraquat is incurable once they drink it.

This is mainly because paraquat is a herbicide that is highly toxic to humans, and so far there is no antidote to paraquat toxicity to humans.

Paraquat was not originally a poison, but a herbicide. In general, paraquat is used only to facilitate the removal of weeds. Despite its name, paraquat is actually so effective that many people call it paraquat.

It is mainly sprayed, so that some weeds absorb a series of changes, and finally cause the weeds to die.

Once a person has consumed paraquat, there is no cure, mainly because paraquat is not meant to be drunk by humans, it is a pesticide that is used to control weeds. However, if paraquat is consumed, it becomes a poison that can cause irreversible damage to the internal organs. When scientists study paraquat, they don't intend to use it on humans, but on grasses, so they don't study the antidote to paraquat.

A person who drinks paraquat inevitably dies. This is because when a person drinks paraquat, the entire internal organs change, starting with the throat and esophagus. Immediately afterwards, paraquat can damage a person's lungs, causing the loss of function of the entire lungs.

The deadliest aspect of paraquat is that it causes fibrosis throughout the lungs. So personally, I don't think we should use paraquat anymore.

Because paraquat is highly toxic and can slowly damage the lungs, leading to pulmonary fibrosis and multi-organ failure, there is currently no effective antidote.

Because paraquat is a poison, it can be said that drinking paraquat is unlikely to survive today.

Also known as the 'grass shark', paraquat is a highly effective herbicide that is inherently highly toxic. It is formed by the reaction of pyridine, metal sodium, and chloromethane, and is easily soluble in water. Contact with the soil quickly fails, so it will not hurt the roots of the plant, but for people, the toxicity is huge, and there is no medicine to **, its toxicity is staggering.

Let's take a look today to find out what the symptoms of paraquat poisoning are.

Toxic pathology of paraquat

Paraquat is also known as "paraquat lung" because the toxicity does not take effect immediately after poisoning, but instead transfers to the lungs, producing large amounts of oxygen radicals that are harmful to tissues, which can quickly destroy the body's defenses and eventually lead to fibrosis in the lungs. Because the human body cannot degrade the toxicity of paraquat in the body, it is also excreted in faeces and urine during poisoning, and even so, the mortality rate of paraquat is terrible, with a fatality rate of 90-100%.

Symptoms of paraquat poisoning

First of all, you will feel a burning sensation in your mouth and throat, accompanied by nausea, dizziness, vomiting and other uncomfortable symptoms, if you have contact, you will have dermatitis and burns at the contact point, and if your fingernails are in contact, it will cause white spots on your nails, and even eventually fall off. This is followed by abdominal pain, hematemesis, hematochezia and other symptoms, followed by pain in the liver, hepatomegaly and other symptoms.

Eventually, paraquat poison enters the lungs, and in the most severe cases, patients will experience chest tightness, coughing, difficulty breathing, pulmonary hemorrhage, etc., and may die in 1-3 days in severe cases, while in general, patients will slowly develop pulmonary fibrosis and die, which will take about 1-2 weeks.

First aid for paraquat poisoning

If contact is only, immediately remove clothing that has been in contact with paraquat and rinse the contact with water as soon as possible. If paraquat is taken orally, vomiting should be induced immediately, and gastric lavage should be required upon arrival at the hospital.

The excretion of poisons can be carried out under the doctor's **, for example, hemoperfusion combined with hemodialysis, this method is mostly used in the case of human poisoning, the principle is that through physical adsorption, the toxins in the body can be removed, the immune function can be regulated, and at the same time the microcirculation can be improved, free radicals can be removed, and the incidence of pulmonary fibrosis is reduced, and the mortality rate is reduced.

It is because it is a very powerful poison, and after drinking it, our body will quickly deplete and die in a dozen seconds.

Because the toxicity of babarella is very strong, and there is no specific drug at present, the possibility of being able to ** after drinking it is very low.

Because paraquat is so toxic that it can quickly kill multiple organs in the shortest amount of time, death is a certainty.

As long as you take a sip, you will definitely die, and even if you don't die, it will cause great damage to your body; Paraquat is very toxic, as long as it is drunk, it will produce a large number of harmful oxygen free radicals, quickly corrode the body's organs, destroy the defense mechanism of various cells, and gradually make the lungs fibrotic, and eventually die of respiratory failure.

Paraquat is terrible because it is very toxic. As long as you drink a little paraquat, you can be poisoned.

It is particularly scary because this poison is particularly toxic, can cause organ failure in a short period of time, and has a particularly high mortality rate.

Paraquat, the king of herbicides, has grown everywhere it walks, so you can imagine how toxic it is. In addition to being highly lethal to plants, paraquat is also very harmful to humans.

1. Direct contact reaction.

Paraquat can cause swelling, edema, and ulceration in the mucosal layers of the oropharynx, esophagus, stomach, and small intestine.

2. Digestive tract reactions.

Once paraquat enters the gastrointestinal tract, about 5-10% of paraquat is rapidly absorbed, and then the toxicity spreads to the lungs, liver, kidneys, and muscle tissue, where it slowly erodes.

3. Acute renal failure.

The kidneys are the most important excretory organs, and paraquat vacuolals the proximal tubular cells of the kidneys, resulting in tubular necrosis. Acute tubular necrosis can be caused by the disappearance of 24 after accidental ingestion, and when the kidneys are damaged, the excretion of toxicity in the body will be slowed down, thus further causing comprehensive or bad damage to the human body.

4. Pulmonary fibrosis.

Appears 2 to 14 days after poisoning, and is characterized by pulmonary hemorrhage, impaired gas exchange, and will show symptoms of "SARS" such as pulmonary fibrosis, until death from hypoxia. This is also one of the most serious and common symptoms, and most poisoned patients are conscious, but eventually die of asphyxiation.

Mild poisoning: intake < 20mg kg, gastrointestinal reactions, temporary decline in lung function, no symptoms of organ failure.

Moderate poisoning: Ingestion of 20-40 mg kg, organ damage, pulmonary fibrosis occurs after a few days, and most people die within 14-21 days.

Fulminant poisoning: ingestion >> 40 mg kg, oropharyngeal erosion and ulceration, with multi-organ failure, most of whom die within a few hours.

Paraquat is absorbed through the digestive tract, ** and respiratory tract, and its toxicity affects multiple organs throughout the body, and in severe cases, it can lead to multi-organ insufficiency syndrome (MODS), the lungs are the main target organs, which can lead to paraquat lung, which manifests as acute lung injury ALI or acute respiratory distress syndrome (ARDS) in the early stage, and intraalveolar and pulmonary interstitial fibrosis in the later stage, which is the main cause of death from paraquat poisoning, with a case fatality rate of up to 50% to 70%.

Paraquat is a highly toxic pesticide, and taking more than 5 ml of paraquat is considered a lethal dose, but it does not die immediately after taking it, and will survive for about half a month to a month. Its main target organ is the lungs, and alveolar fibrosis eventually leads to the inability of alveolar oxygen delivery into the bloodstream, and finally the patient suffers from breathing difficulties and dies of respiratory failure. There is currently no specific antidote to paraquat poisoning, so it is important to take care to prevent paraquat poisoning.

The drug must be kept out of the reach of children, and it is necessary to avoid accidental ingestion of paraquat, **contact is also a route of poisoning, and attention must be paid to avoid **contact** as much as possible.

Your adoption is my greatest support! Break a leg! Thank you!

Yes, paraquat can cause gastrointestinal congestion, which can lead to organ failure and death. This is a very cruel and undignified death.

Because after drinking, there will be a strong chemical reaction.

I drank it in a hurry and regretted it.

There is a direct correlation between the time of death and the patient's intake of paraquat, but most patients with less than 20 mg are not life-threatening.

If the intake is between 20 and 40 mg, in addition to obvious gastrointestinal symptoms, the patient's functional damage is also very serious, generally in about a week, lung and liver function will decline rapidly, and death will occur after 2 to 3 weeks.

After the intake is greater than 40 mg, it is an explosive severe disease, and the patient will have a large failure of organs in about a day, and death will occur in about a week, and the survival rate of this type of patient is very low.
