What Are the Symptoms of Iodine Poisoning?

Iodine is a purple-black crystal, which can sublimate and evaporate at room temperature to release iodine vapor. Common poisoning is caused by inhalation of a large amount of iodine vapor or taking iodine. Oral poisoning iodine includes iodine crystals, iodine tincture, Lugol's solution (containing 5% iodine), potassium iodide (containing potassium iodide 10%), iodine glycerol (containing iodine 3%), and the like. Iodinepoisoning in children is mostly caused by accidental use or excessive dosage; children mistakenly taking 3 ~ 4ml of iodine tincture can cause death; 7-year-old children have been seen to die of anaphylactic shock caused by iodine tincture.

Iodine-containing preparations such as iodine tincture, compound iodine solution, iodine laryngeal tablets, and iodine glycerol are widely used medicines in medicine. Iodine tincture is a disinfectant drug commonly used in households. Iodine poisoning in children is mostly caused by accidental use or excessive dosage. Some people once took iodine tincture as a cough syrup and gave it to children. A small number of sick children are allergic to iodine, and the treatment dose also has serious reactions. Children mistakenly take 3 ~ 4mL of iodine tincture can cause death.

Children mistakenly take a higher concentration of iodine, which has a strong irritating and corrosive effect on the gastrointestinal tract. After absorption, it reacts with proteins in the tissue and causes systemic poisoning. The iodine smell in the oral cavity, burning, pain in the oral cavity, esophagus, and stomach, edema in the oral cavity and throat, and brownish color, which can cause scars and stenosis of the esophagus and stomach. Sick children also show symptoms of dizziness, headache, thirst, nausea, vomiting, diarrhea, fever, and blood in the stool. Severely poisoned children are pale, shortness of breath, cyanosis, tremor in the limbs, blurred consciousness, loss of orientation, sensory disturbances, confusing speech, and even coma, shock, or toxic nephritis with hematuria and proteinuria. Severe cases cause acute kidney disease. Functional failure. Allergic children can cause anaphylactic shock.

Due to the corrosive nature of iodine preparations, it may cause edema of the throat, even suffocation, and severe symptoms may also cause coma. If not rescued in time, it can cause severe hypoxia in the brain, damage the central nervous system, and affect children's intellectual development. Therefore, we should keep the iodine preparations in a safe place, and prevent them from being taken by children. Especially, iodine laryngeal tablets should be taught to children not to take more. In addition, iodine tincture should be placed separately from cough syrup, and the name should be marked to prevent iodine tincture from being used as cough. Syrup is given to children to prevent poisoning. If taking a large amount of iodine preparations, they should be immediately sent to the hospital for treatment, which can reduce symptoms.

What are the symptoms of iodine poisoning and what to do after it?

After oral poisoning, the mouth has an iodine smell, edema in the mouth and throat, brown stains, and a burning sensation in the esophagus and stomach. Sick children have headache, dizziness, thirst, nausea, vomiting, diarrhea, and fever: the vomit is yellow-brown. If there is starch in the stomach, the vomit is stained blue, which can cause blood. Severe tremor, limb tremor, pulmonary edema, cyanosis, delirium, convulsions, shock caused coma. Toxic nephritis can even lead to acute renal failure. Iodine can corrode the esophagus and gastric mucosa, and scars and stenosis of the esophagus or stomach may remain after healing.

Rescue and treat iodine poisoning immediately by taking a large amount of starch orally (such as rice soup, noodles, porridge, potato, bread, etc.), so that it absorbs iodine and reacts with blue, and then induces vomiting: gastric lavage can use 1 to 10% starch solution (rice soup (Also) or 1% sodium thiosulfate solution. Until the eluent is blue. After gastric lavage, diarrhea was relieved with sodium sulfate. Orally take raw egg whites, milk, and edible vegetable oils to protect the gastric mucosa. Laryngeal edema can cause respiratory tract obstruction and suffocation. Tracheotomy must be performed immediately. Angioedema caused by iodine allergic reactions can also cause obstruction of the throat, and tracheotomy should be performed with adrenal corticosteroids.

Children who are poisoned by oral iodine preparations should immediately give children a large amount of starchy foods, such as rice soup, rice noodles, noodles, porridge, bread, biscuits, etc., and then induce vomiting. Then use 1% to 10% starch solution or rice soup to lavage the stomach, or use 1 Stomach lavage with a sodium thiosulfate solution until the washing liquid is blue. After the gastric lavage, diarrhea is taken orally, and rice soup, raw egg white, milk, vegetable oil, etc. are taken orally to protect the gastric mucosa. Severe laryngeal edema should be given oxygen, and the trachea should be opened immediately when suffocation is caused, and artificial respiration should be performed. Also pay attention to symptomatic treatment.

"Excessive" iodine generally means that one or more intakes significantly exceed the upper limit of the human body's safe range, but it does not necessarily have a manifestly harmful effect. Iodine "poisoning" means that iodine intake not only greatly exceeds the upper limit of the safe range, but also has different types of symptoms of poisoning. When the daily intake of iodine exceeds 1000 micrograms, and excessive iodine may occur for several weeks. Today, when iodized salt is consumed, the daily intake of iodine through iodized salt is about 200 micrograms, which is safe for the human body. Accidents of iodine poisoning have also been reported in the past, mainly for several reasons: such as eating a large amount of iodine for a short period of time; taking iodine is a species that is excreted more slowly in the body; different people have different tolerances to iodine, and this occurs People in this situation are often individuals who are more sensitive to iodine.
