Poisoning with mushroom poisons of neurovegetotropic effectIn poisoning with Amanita rubescens a clinical picture of poisoning with muscarine and muscaridine develops since this mushroom contains them. Amanita pantherina contains atropine-like substances — scopolamine and other amines. Muscaridine causes atropine-like reaction and muscarine — proserine-like symptomatology of poisoning. A clinical picture of poisoning with these mushrooms depends on the ratio of the contents of the above-mentioned poisons in mushrooms. An injurious effect on CNS is manifested with skin hyperemia, tachycardia,visual hallucinations, convulsions, disorder of consciousness up to coma. In proserine-like poisoning — paleness of skin coverings, disorder of hemodynamics and cardiac activity, convulsions, gastrointestinal disorders are noted. A latent period is from 25 min to two hours. A period of neurologic disorders starts in 25-120 min and reaches its maximum in 2-4 hours since the moment of mushroom ^consumption. In grave cases of poisoning we may observe a disorder of cardiac activity, convulsions, cerebral edema, paralysis of respiratory muscles that may last 2-3 days. Treatment: a complex of measures stipulated by the main principles of intensive care of poisonings, situational and correction therapy. In poisoning with mushrooms of neurovegetotropic effect — antidote therapy planning an atropine administration prior to symptoms of the overdosage in proserine-like poisoning, and proserine — in atropine-like poisoning. Of methods of situational therapy it is necessary to envisage a possibility to apply oxygen inhalation, APV, dopamin administration, blood oxygenation and anticonvulsant therapy.
