Poisoning the WCF

фосфор в периодической системе Phosphorus and its compounds are the right substances in the human body. This is one of the main components of proteins, enzymes in vital reactions that occur daily. Thanks to phosphorus, our bones and teeth have a strong structure, and the human body can make active movements. A nervous system without its connections cannot work productively.

Without a doubt, phosphorus is needed in every cell. But he possesses not only useful properties, some of his compounds, artificially created by man, are harmful. Is it possible to overabundance of phosphorus in the body, what kind of substances and in what quantity will cause poisoning with this element?

Phosphorus compounds around us

It will be a question of chemicals which in the industry and in life carry the name FOS (FOV). Organophosphate compounds are a group of complex substances that contain phosphoric acids.

в чем содержится фосфор

Where are organophosphates used?

  1. обработка растений удобрениями с фосфором In agriculture for the processing of orchards, vineyards, vegetables and grains.
  2. To combat animal parasites.
  3. In service with the army as chemical warfare agents (sarin, soman and V-gases).
  4. In medical practice (drops in ophthalmology, in surgery preparations for the normalization of the muscles of the gastrointestinal tract, in the treatment of pediculosis).

Everyone can encounter one of the derivatives of phosphorus in their lives without knowing it. Therefore, it is necessary to be fully armed if FOS is poisoned.

Organophosphate compounds are most often solid or liquid volatile substances, most of which have a specific kerosene-garlic odor. Well soluble in fats and poorly in water. The toxicity of aqueous solutions at a temperature of 35 ° C day increases to 35 times.

Organophosphate compounds are part of many things that people face daily in their lives. They enter the body mainly through the respiratory tract, the digestive system or the skin. Organophosphate poisoning occurs when contaminated water is consumed, foodstuffs treated with such substances, when FOS comes in contact with the skin during the treatment of rooms, clothes and linen.

Once inside a person, organophosphorus compounds are rapidly absorbed in the mouth, then in the stomach and intestines. Almost instantly enter the blood. Organophosphate poisoning is dangerous due to its consequences: about 50% of FOS is converted into more toxic compounds in the body, and cyclical transformation is characteristic of the poison. That is why 8–10% of people who have experienced only once with FOS poisoning have relapses. In this case, repeated contact with any phosphorus compound was not observed. This condition is called chronic phosphorus intoxication.

damage to the nervous system

Organophosphate compounds primarily affect the nervous system. In the development of acute poisoning, it is customary to distinguish three periods.

  1. Acute - the first three days.
  2. The period of complications is from the 4th to the 14th day.
  3. The period of remote consequences, which can last up to three years.

The acute period of phosphorus poisoning is characterized by the excitation of body systems. Affected central and peripheral nervous system, which is expressed in the following symptoms.

  1. Blurred vision
  2. последствия отравления фосфорорганическими соединениями Excessive secretion of saliva - hypersalivation, increased sweating.
  3. Bronchospasm, bradycardia or a decrease in heart rate.
  4. Intestinal motility increases, spasmodic pains appear, and stool is later disturbed as diarrhea.
  5. The symptoms of phosphorus poisoning include muscle weakness, muscle twitching of various groups.
  6. Paralysis of the respiratory muscles, respiratory failure.
  7. Signs of damage to the central nervous system: agitation, shortness of breath, the appearance of convulsions, an abnormal heart rhythm, an increase with a subsequent decrease in pressure, an increase and a decrease in temperature.
  8. If a poisonous substance enters the body in high concentration, confusion, coma, paralysis of the respiratory center occurs.

pressure reduction

In the second period of the development of poisoning, the symptoms somewhat subside, but other signs join them.

  1. Lack of reflexes.
  2. Cyanosis of the skin.
  3. Reduced pressure.
  4. Edema of the brain.

Additionally, in the second stage of phosphorus intoxication, pneumonia, toxic hepatitis, and kidney damage can join.

The third period - long-term effects, which affect the neuromuscular system, kidneys and liver.

Diagnosis of FOS poisoning

The diagnosis is based on symptoms of damage to the nervous system:

  • диагностика отравлений ФОС
    blurred vision

    muscle twitching;

  • bumps;
  • hypersalivation;
  • impaired vision;
  • violation of the bowel.

You need to carefully inspect the place where the victim was. The presence of a specific kerosene-garlic smell from unfamiliar substances may give rise to the idea of ​​the presence of FOS in the room. In the subsequent biochemical blood test will help to finally make a diagnosis.

During acute poisoning secrete lightning and slow-flowing forms. In victims of the fulminant convulsive syndrome develops within 30 minutes after contact with organophosphorus compounds.

Emergency care in organophosphate poisoning

First aid in case of poisoning with phosphorus compounds depends on the way the chemical agent enters the body.

  1. If FOS got through the mouth of the victim immediately washed the stomach with a probe, injected magnesium sulfate, activated charcoal, liquid paraffin.
  2. In case of inhalation poisoning, a person should be immediately taken out of the room, the stomach should be flushed, a laxative and an antidote (antidote) should be administered.
  3. Affected skin should be washed with soap and water, 2% soda solution, treated with chloramine.

Treatment of FOS poisoning

If you suspect poisoning with phosphorus compounds, all people are subject to emergency hospitalization in the intensive care units of hospitals.

лечение отравлений ФОС Antidotes for organophosphate poisoning are:

  • "Diazepam";
  • "Atropine sulfate";
  • "Dipyroxime";
  • "Izonitrosin".

Prevention of FOS poisoning

профилактика отравлений ФОС To avoid infection, you need to follow safety rules.

  1. Work with phosphorus compounds only in closed clothes, so the substances will not fall on the skin.
  2. Prevention of FOS poisoning - do not allow children to tanks containing this product, dispose of the container in time.
  3. In the case when the poison got on the clothes - it should be removed immediately, cut hair and nails cut off.

The specific signs of phosphorus poisoning are damage to the nervous system at all levels. Each organ can be affected by acute poisoning with FOS. The only correct decision that must be made in case of suspected poisoning is timely hospitalization in the hospital. This will not only save the life of a person, but also save him from chronic serious illnesses afterwards.
