ORGANOPHOSPHATE TOXICITY

Course overview

ORGANOPHOSPHATES ENCOMPASS A DIVERSE GROUP OF CHEMICAL COMPOUNDS WITH COMMON APPLICATIONS IN PESTICIDES AND HERBICIDES, AS WELL AS NERVE AGENTS IN CHEMICAL WARFARE. WHEN INTRODUCED INTO THE BODY, ORGANOPHOSPHATES INHIBIT THE ENZYME ACETYLCHOLINESTERASE, RESULTING IN AN OVERABUNDANCE OF THE NEUROTRANSMITTER ACETYLCHOLINE. THIS SURPLUS OF ACETYLCHOLINE IN THE BODY MANIFESTS WITH CHOLINERGIC TOXIDROME, WHICH INCLUDES EFFECTS ON NICOTINIC AND MUSCARINIC RECEPTORS, AS WELL AS THE CENTRAL NERVOUS SYSTEM. RESPIRATORY FAILURE RESULTING FROM BRONCHORRHEA AND BRONCHOSPASM IS THE LEADING CAUSE OF DEATH IN CASES OF ORGANOPHOSPHATE TOXICITY. CHRONIC TOXICITY AND NEUROLOGICAL COMPLICATIONS, SUCH AS THE INTERMEDIATE SYNDROME, ARE ALSO WELL DOCUMENTED. ALTHOUGH DEVELOPED NATIONS HAVE EXPERIENCED A DECLINE IN POISONING CASES DUE TO STRICTER REGULATIONS ON THE USE OF THESE CHEMICALS, DEVELOPING COUNTRIES STILL FACE A CLINICAL CONCERN, ESPECIALLY WHEN THESE CHEMICALS ARE USED FOR SELF-HARM PURPOSES. ANTIDOTAL THERAPY AND COMPREHENSIVE SUPPORTIVE CARE FROM HEALTHCARE PROFESSIONALS ARE NECESSARY FOR THE EFFECTIVE TREATMENT OF ORGANOPHOSPHATE TOXICITY TO PREVENT MORBIDITY AND MORTALITY. THIS ACTIVITY REVIEWS THE ASSESSMENT AND TREATMENT OF ORGANOPHOSPHATE TOXICITY WHILE HIGHLIGHTING THE ROLE OF THE INTERPROFESSIONAL HEALTHCARE TEAM IN RECOGNIZING ORGANOPHOSPHATE TOXICITY AND TREATING PATIENTS WITH THIS CONDITION.
