Poisoning with antifreeze and antifreeze: symptoms and consequences
What happens if you drink antifreeze
Antifreeze is a tool which is faced by every car owner. Therefore contact with this substance inevitable. What will happen to the man if you drink antifreeze? Sensitivity to poison every single person individual. Small doses of the substance can cause serious poisoning in children and animals.
Components of antifreeze and their effect on the body
Antifreeze is a liquid that does not freeze at low temperatures from 0 to -75 °C. It is used for cooling the engine. As the antifreeze used aqueous solutions of ethylene glycol, propylene glycol, glycerin, alcohols. Their composition also includes a corrosion inhibitor and fluorescent additives (silicate, carboxylate). The antifreeze is added the dyes, which impart color.
According to GOST, the ethylene glycol is a poisonous chemical compound, can permeate through the skin and by inhalation. The substance has a destructive effect on the cells of the liver, kidneys, and nervous system. Toxic effects on sexual function: in men develop impotence in women disrupted menstrual cycle. The concentration of ethylene glycol according to the sanitary standards shall not exceed in the air 0.005 g per m3. Nevertheless, in the cabin of the car it is always a little more.
The effect on the human body, propylene glycol is not toxic. It is used as an analogue of ethylene glycol to protect children and animals from accidental ingestion and poisoning.
Manufacturers produce antifreeze under different commercial names: antifreeze, UAS. Marking HP-40 or HP-65 is the temperature of their freezing.
Symptoms of intoxication antifreeze
Intoxication usually occurs by ingestion of the substance inside (digestive tract). The poisoning of antifreeze through the respiratory tract, the eyes or the skin happens rarely. Minimum toxic dose for humans is 50 ml. Lethal dose of antifreeze is 100-300 ml.
The initial stage of poisoning
Immediately after the coolant spill into the stomach the man may feel slight drunkenness that lasts for long. Then it is replaced by the phase of sleep – the first sign of damage to the nervous system with antifreeze. Significant deterioration occurs within 12 hours.
The initial symptoms of antifreeze poisoning:
- intense headaches;
- violation of movement coordination, loss of balance;
- muscle cramps.
Manifestations of lesions of the gastrointestinal tract in cases of poisoning by antifreeze – nausea, vomiting after eating, which does not bring relief. A person feels abdominal pain, radiating to the back and spine.
Disturbed function of vision:
- double vision;
- flies flashing;
- the reduced clarity of the image;
- photophobia, transient blindness.
Antifreeze poisoning is characterized by symptoms of General intoxication: a decrease in body temperature and blood pressure, chills. The skin becomes pale with a gray tint.
Phase of renal
On the second day after ingestion of the antifreeze rapidly developing symptoms of lesion of internal organs – kidneys and liver, which is the harbinger of severe poisoning.
The kidney is the first organ after the nervous system, which falls under the blow of antifreeze. Lose body is the result of synthesis of ethylene glycol to glycolic and oxalic acids (has moderate toxicity, is deposited in the kidneys in the form of concretions).
Functional disorders caused by antifreeze pose a threat to life and manifest symptoms such:
- the decrease in daily diuresis – decrease in urine;
- the high content in the urine protein and red blood cells;
- increased ESR (erythrocyte sedimentation rate);
- in the blood the presence of uric acid – the result of violations of nitrogen metabolism.
If you do not take timely measures to remove the antifreeze from the body, the victim developed acute renal failure. Symptoms of kidney:
- anuria – lack of urine;
- hematuria – blood in the urine;
- arrhythmia of the heart.
Against the background of these symptoms develops uremia delay in the body of toxic substances, nitrogenous degradation products. Disturbed water-salt metabolism.
With adequate treatment, this condition is reversible. Severe poisoning with antifreeze leads to uremic coma with a fatal outcome.
Phase of liver injury
Because the liver is actively opposed to the effects of toxic substances in antifreeze, the symptoms are lesions appear later, 3-5 days, sometimes latent period is prolonged to three weeks.
Clinical manifestations of liver damage antifreeze:
- pain in the right upper quadrant;
- enlarged liver, tenderness;
- excessive thirst due to low urine output;
- acidosis – acidification of the body;
- in the blood of a large number of leukocytes;
- high blood pressure.
If you do not stop the process of destruction of cells, the poisoning can become chronic with a deep dystrophic changes in the liver (jaundice, ascites, cirrhosis).
Phase of brain damage
The ethylene glycol acts as a narcotic, and has the excitatory and paralytic effects. In single dose of high concentrations of antifreeze after 2 hour develops such characteristics:
- redness of the mucous membranes and skin, followed by cyanosis;
- excited behaviour, restlessness;
- atactic gait is wobbly, unstable, requiring a larger area of the support;
Inappropriate behavior is a violation of the mechanism of transmission of nerve impulses from the brain to nerve endings. Such is the impact of toxic substances on the nerve cells. Gradually, the anxiety is replaced by apathy, and replaced the euphoria comes depression.
The physiological symptoms of brain damage in cases of poisoning by antifreeze:
- frequent vomiting due to irritation of the vomiting center;
- increased tone of the muscles of the neck;
- trembling of the hands and feet;
- clonic seizures;
- loss of sensitivity of skin receptors.
In severe cases, there is hypersalivation (drooling), urinary incontinence and fecal incontinence. Pupils dilate, and there is no reaction to light. Breath becomes superficial, unstable. Frequent heartbeat bradycardia is replaced. Blood of the transcendent content of neutrophils, which indicates a severe intoxication. The phase lasts a maximum of 48 hours, and in the absence of treatment goes into a coma. May occur death.
The poisoning of antifreeze leaking with less severe symptoms and life-threatening is not.
Immediately after receipt of antifreeze inside needs to quickly wash out the stomach. You need to prepare a 2% soda solution. Method of preparation: in one liter of water take 20 grams of baking soda, stir well until it dissolves completely.
Give the victim to drink the mixture for 5 minutes. Then, pushing down on the tongue with two fingers, induce vomiting.
If there are no soda, washing is done with ordinary water.
Before the arrival of the ambulance or if transport of the victim needs warmth to tuck and permanently provide drinking water to increase urine output and prevent renal failure.
Treatment in a hospital
Special antidote therapy in poisoning with antifreeze does not exist. First aid is bleeding. This method is used in case of poisoning and poisonous substances that are difficult are removed from the body and long circulate in the blood stream. The purpose of the method is to remove a certain amount of blood by venipuncture. After the procedure is carried out the transfusion of donor blood.
To maintain renal function, prevent symptoms of dehydration prescribe intravenous solutions of glucose, saline (0.9% NaCl), 500 or 1000 ml.
Cardiac glycosides – tone the heart muscle, making her normally shrink, relieve swelling, prevent the development of symptoms of hypoxia (oxygen starvation of cells). Drugs korglikon, digoxin, adonizid.
Respiratory analeptics stimulate the respiratory center of the brain, exert drug action. Drugs: tsititon, etimizol, Lobelia.
Dehydrating agent – take liquid from the tissues into the blood stream and excrete it from the body. Prevent disturbance of the water balance. Drugs: mannitol, urea.
Anti-convulsants – these medications stop the muscle cramps, spasms, eliminate epileptic seizures. Drugs: phenytoin, phenobarbital, and clonazepam.
To combat the symptoms of acidosis (increased acidity) is a 3-5% solution of sodium bicarbonate.
Injection of magnesium sulfate is indicated for the excretion of oxalic and magnesium salts.
Symptomatic treatment of poisonings with antifreeze:
- thiamine (vitamin B1) – supports the heart and nervous system;
- pyridoxine (vitamin B6) is a stimulator of metabolic processes in the body;
- cyanocobalamin (vitamin B12) – has beneficial effects on the nervous system, heart muscle, the blood;
- ascorbic acid restores metabolic processes, regulates the acidity of the body.
Interesting fact! If you accidentally drank antifreeze, then the best antidote is alcohol. This was confirmed in medical practice, doctors from the UK. When the hospital received a patient who had been drinking accidentally a small amount of antifreeze, the doctor immediately gave her to drink as much whiskey. The woman was recommended to take this strong drink during the first days after poisoning, every hour on the throat. This experiment was a success. The poisoning has passed without serious consequences for the organism.
If the person is a long time, breathed a couple of freeze and feel sick, it needs to be put to bed and organize the circulation of fresh air in the room. To provide a sufficient amount of drinking. First aid, depending on the symptoms of poisoning – warm with fever, give antipyretic if fever, pain migraine.
If antifreeze gets on your skin, this place should be thoroughly rinsed under running water for 5-10 min. Dry clean dry towel. Health risks contamination of the skin is not.
The outcome of the poisoning with antifreeze is usually favorable, the period of recovery depends on the extent of involvement of internal organs. In order to prevent poisoning of the body with the cooling liquid, it is necessary to observe safety when using it. To exclude the possibility of getting antifreeze in the hands of the child.
