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 ]
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.
Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. [1] It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant – alters the normal activity of the nervous system in such a ...
General chemical structure of the organophosphate functional group. In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure O=P(OR) 3, a central phosphate molecule with alkyl or aromatic substituents. [1] They can be considered as esters of phosphoric ...
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 ...
The magnitude of ethanol neurotoxicity in fetuses leading to fetal alcohol syndrome has been shown to be dependent on antioxidant levels in the brain such as vitamin E. [108] As the fetal brain is relatively fragile and susceptible to induced stresses, severe deleterious effects of alcohol exposure can be seen in important areas such as the ...
Furthermore, certain organophosphates can cause OPIDN, organophosphate-induced delayed polyneuropathy. This is a disease, which is characterized by degeneration of axons in the peripheral and central nervous system. This disease will show a few weeks after contamination with the organophosphate.
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.
