It is an important sign of organophosphorus pesticide poisoning due to increased secretion of glands and more secretions with “garlic odor” in the mouth and respiratory tract of the poisoned person. So, how to diagnose the garlic odor of breath? Here is the analysis. Symptom diagnosis The time and severity of the symptoms of garlic odor in the breath are closely related to the route of entry, the nature of the pesticide, the amount of entry and absorption, and the health condition of the human body. General acute poisoning mostly develops within 12 hours, if it is inhalation, oral high concentration or highly toxic organophosphorus pesticides, symptoms and even death can appear within a few minutes to ten minutes. Skin contact poisoning has a slower onset, but can show serious symptoms after absorption. Early or mild cases of this type of pesticide poisoning may show dizziness, headache, nausea, vomiting, salivation, excessive sweating, blurred vision, and weakness. In addition to the above-mentioned symptoms, more severe cases have narrow pupils, muscle tremors, lacrimation, increased bronchial secretions, dry and wet rales and rales in the lungs, abdominal pain, diarrhea, confusion, staggering, bradycardia, fever, chills, etc. In severe cases, there are often abnormal heart rhythm such as tachycardia, atrioventricular block and atrial fibrillation, increased or decreased blood pressure, cyanosis, dyspnea, froth at the mouth and nose or even with blood (pulmonary edema), convulsions, coma, incontinence or retention of urine, paralysis of limbs, loss of reflexes, etc. Death may occur due to respiratory paralysis or circulatory failure. Inhalation poisoning patients, respiratory and eye symptoms appear earlier, oral poisoning often occurs first gastrointestinal symptoms, skin contact poisoning with local sweating and adjacent muscle fiber contraction as the initial manifestation, dichlorvos and skin contact with more erythema-like changes, gradually become blisters, the child has itching, burning sensation. Once the breath is garlic odor, if it is oral poisoning, immediately wash the stomach, while inducing vomiting, and use drugs to detoxify. If poisoned by inhalation while spraying pesticides, get out of the poisoned environment immediately, quickly remove the contaminated outer clothing, and flush the contaminated parts with soapy water and running water. If the symptoms are severe, take the patient to a hospital for emergency treatment immediately after initial treatment.
