Dry and burning throat
Introduction
Introduction Zinc poisoning is mainly due to the preparation or storage of acidic beverages using galvanized vessels, in which case the acidic solution can decompose more zinc to cause poisoning. Other reasons are medicinal zinc oxide (usually used as astringent) or zinc sulfate (usually used to treat conjunctivitis) or large area wounds to absorb zinc oxide (often mildly astringent or antiseptic powder), after misuse of zinc salt There are mouth, pharynx and digestive tract erosion lips and glottis swelling, abdominal pain, diarrhea, vomiting and water and electrolyte disorders, severe cases of high blood pressure, shortness of breath, dilated pupils, shock, convulsions and other crises. After inhalation of zinc oxide dust, there may be a dry throat and a burning sensation, hoarseness or even a loss of sound, and a metallic taste and chest in the mouth.
Cause
Cause
Causes of dry throat and burning sensation
Poisoning is caused by accidental administration of large doses of zinc preparations and inhalation of zinc-containing dust.
Inhalation of zinc oxide soot: 1 casting heat: short incubation period generally 1 to 8 hours after inhalation, sudden chills last for 1-2 hours, high fever up to 38-40 ° C, may be accompanied by headache, dizziness, fatigue, sweating, Muscles and joints, acidity, tinnitus, etc., similar to the "malaria" episodes, respiratory symptoms, gastrointestinal disorders, severe neurological symptoms such as convulsions, jealousy and confusion, physical examination can find pulse rate, The throat is congested, the lungs are in the voice, the breath sounds are rough, etc.; repeated authors may have hepatomegaly, tenderness, elevated transaminase, anemia, etc. General fever lasts for 6-7 hours, and symptoms worsen within 24-48 hours. 2 respiratory symptoms: after inhalation of zinc oxide dust, there may be dry throat and burning sensation, hoarseness or even loss of sound, metal taste, chest and so on. The lighter gradually recovers after 2-3 days. In severe cases, bronchitis, pneumonia and pulmonary edema may occur, and dyspnea, hypoxia and hair loss may occur. Long-term inhalation of zinc stearate dust may cause pneumoconiosis and cough and cough. , shortness of breath, hemoptysis, chest and so on.

Dry throat and burning sensation
Inhalation may be complicated by bronchitis, pneumonia and pulmonary edema and dyspnea, hypoxia and hair loss, long-term inhalation of zinc stearate dust, can cause pneumoconiosis and cough, cough, shortness of breath, hemoptysis, chest and so on.
Those who are severely convinced may have shortness of breath, rapid pulse rate, increased blood pressure, enlarged pupils, convulsions, coma, shock, etc. Even after a little late death or temporary recovery, kidney damage occurs, such as low back pain, proteinuria, hematuria, and tubular urine.
Salts that are misused by zinc: may have oral mucosa and digestive tract erosion, pain in mouth, throat and abdomen, swelling of the lips and glottis, and thirst, nausea, vomiting, diarrhea, etc.; vomiting is purple-blue, stool Blood and even perforated peritonitis may also cause water and electrolyte disturbances. In severe cases, there may be rapid breathing, pulse rate, elevated blood pressure, dilated pupils, convulsions, coma and shock, etc. Even after a little late or after temporary recovery Renal damage occurs with low back pain, proteinuria, hematuria, and tubular urine. Some patients may have pancreatitis and abdominal pain, nausea, vomiting, abdominal distension, fever, water, electrolytes and acid-base balance disorders, diabetes, ketonuria, severe poisoning patients often have stomach and esophageal stenosis after the acute phase, and A series of symptoms and signs appear.
What should I do for zinc poisoning?
Determination of Toxic (Zinc) by Flame Atomic Absorption Method Blood zinc and urine zinc are higher than normal, white blood cells are increased, neutrophils are shifted to the left, platelets can reduce multiple acute attacks and can cause anemia, blood sugar is increased, urine sugar is positive, urinary bladder The increase in hormones, occasionally leaf urinary urinary, elevated transaminase.
Diagnosis
Differential diagnosis
Throat dryness and burning sensation are distinguished from other poisoning
Low-chlorine alkalosis: Low-chlorine alkalosis is a type of metabolic alkalosis, which is more common in the pediatric intensive care unit. Metabolic alkalosis is harmful to the body, in addition to causing acid-base balance and electrolyte imbalance, Severe cases can be life-threatening. Because it occurs in critically ill children and is based on other diseases (such as respiratory system, digestive system, nervous system, etc.), it is often covered by the primary disease, and the clinical manifestations are diversified. Lack of specificity, so it is easily overlooked, often due to the inability to timely diagnosis and appropriate treatment to make the disease prolonged or aggravated.
Cadmium poisoning: Cadmium poisoning is mainly caused by inhalation of cadmium soot or cadmium compound dust. A large inhalation can cause acute pneumonia and pulmonary edema; chronic poisoning causes pulmonary fibrosis and kidney disease. The industries exposed to cadmium are smelting, spraying, welding and casting bearing surfaces of cadmium, cadmium rods of nuclear reactors or cadmium-coated graphite rods as neutron absorbers, cadmium batteries and other cadmium compounds. Japan reported that "pain" is a chronic cadmium poisoning caused by long-term feeding of water contaminated with cadmium sulfate.
