Clinical information Recently, we have encountered several strange cases of patients with symptoms such as panic, dry mouth, chest tightness, dizziness, blurred vision, hand tremors, etc., after consuming animal offal (liver, lung, kidney, etc.), or with dyspareunia. Physical examination: flushed face, dry skin, dilated pupils, slightly shortness of breath, heart rate of about 120 beats per minute. These are typical manifestations of anticholinergic (atropine, 654-2, etc.) poisoning. Co-feeders or family members with similar symptoms, the milder ones resolve on their own, and those with ECG manifestations of inadequate blood supply are quickly relieved by giving coronary expansion, improving microcirculation and detoxification treatment. Background According to sources, certain livestock are injected with large amounts of atropine before being sold to slaughterhouses for profit because the animals are thirsty for water and do not pull or urinate to gain weight after poisoning. The pharmacology of atropine is an anticholinergic drug, which can release smooth muscle spasm, inhibit glandular secretion, release the vagus nerve inhibition of the heart to speed up the heart rate, dilate the pupil, and excite the respiratory center. Atropine clinical applications: rescue of toxic shock, treatment of A-S syndrome, rescue of organophosphorus pesticide poisoning, relief of visceral colic, preanesthetic use, ophthalmic pupil dilatation. Atropine overdose or poisoning manifestations dry mouth, dizziness, dilated pupils blurred vision, flushed skin, rapid heartbeat, excitement, irritability, delirium, hallucinations, etc. Atropine treatment dosage Adults should not exceed 1mg each time and 3mg per day, lethal dose is 80-130mg, except for rescue of organophosphorus pesticide poisoning. Atropine is a colorless and tasteless crystal extracted from the plants such as Aconite, Belladonna and Scopole, which is easily dissolved in water and can withstand high temperature of 100℃ for 30 minutes. Atropine poisoning can be rescued from acute poisoning by gastric lavage and diarrhea; sedation can be used for excitement, and nikethamide can be used for respiratory depression, and neostigmine can be used as a special antidote.
