signs, symptoms and treatment of organophosphorus poisoning

 Organophosphorus poisoning results from exposure to organophosphate compounds, commonly found in pesticides and nerve agents. Here’s a brief overview:

Signs and Symptoms:

1. Cholinergic Symptoms: Due to overstimulation of the parasympathetic nervous system:

   • Miosis: Constricted pupils
   • Salivation: Excessive drooling
   • Lacrimation: Excessive tearing
   • Urination: Frequent urination
   • Diarrhea: Gastrointestinal distress
   • Gastrointestinal cramps
   • Emesis: Vomiting
   • Bradycardia: Slow heart rate
   • Muscle twitching or fasciculations
   • Respiratory distress

2. Central Nervous System Effects:

   • Confusion
   • Agitation
   • Seizures
   • Coma (in severe cases)

Treatment:

1. Decontamination: Remove contaminated clothing and wash skin thoroughly with soap and water.
2. Atropine: Administered to counteract muscarinic symptoms (e.g., salivation, bronchoconstriction).
3. Pralidoxime (2-PAM): Used to reactivate acetylcholinesterase if given early; it helps restore normal enzyme function.
4. Supportive Care: Monitor vital signs, provide respiratory support if needed, and manage seizures.

Early recognition and treatment are crucial for improving outcomes in organophosphorus poisoning cases.
