Organophosphate poisoning is poisoning due to organophosphates (OPs). [4] Organophosphates are used as insecticides , medications, and nerve agents . [ 4 ] Symptoms include increased saliva and tear production, diarrhea , vomiting, small pupils , sweating, muscle tremors, and confusion. [ 2 ]
Pralidoxime (2-pyridine aldoxime methyl chloride) or 2-PAM, usually as the chloride or iodide salts, belongs to a family of compounds called oximes that bind to organophosphate-inactivated acetylcholinesterase. [1] It is used to treat organophosphate poisoning [2] in conjunction with atropine and either diazepam or midazolam. It is a white solid.
Organophosphate-induced delayed neuropathy (OPIDN), also called organophosphate-induced delayed polyneuropathy (OPIDP), is a neuropathy caused by killing of neurons in the central nervous system, especially in the spinal cord, as a result of acute or chronic organophosphate poisoning.
It is essential to seek medical attention immediately in cases of suspected dichlofenthion poisoning to ensure appropriate treatment and prevent potentially life-threatening complications. Additionally, proper handling and application practices should be followed to minimize the risk of exposure to organophosphate pesticides like dichlofenthion.
Atropine is not an actual antidote for organophosphate poisoning. However, by blocking the action of acetylcholine at muscarinic receptors, atropine also serves as a treatment for poisoning by organophosphate insecticides and nerve agents, such as tabun (GA), sarin (GB), soman (GD), and VX.
Organophosphate insecticides are acetylcholinesterase inhibitors, which disrupt the transmission of nerve signals in exposed organisms, with fatal results. The risk of human death through organophosphate poisoning [32] was obvious from the start and led to efforts to lower toxicity against mammals while not reducing efficacy against insects ...
Common mnemonics for the symptomatology of organophosphate poisoning, including sarin, are the "killer Bs" of bronchorrhea and bronchospasm because they are the leading cause of death, [8] and SLUDGE – salivation, lacrimation, urination, defecation, gastrointestinal distress, and emesis (vomiting). Death may follow in one to ten minutes after ...
Contamination with - or excessive exposure to - certain chemicals including: nerve agents, (e.g., sarin, VX, Novichok agents). organophosphorus insecticides (e.g., parathion, aldicarb) nicotine poisoning can be thought of as a subset of cholinergic crisis, as it also involves excessive parasympathetic stimulation.
