Q26 marksEssays

Answer

Probable diagnosis

  • Organophosphorus (anticholinesterase) poisoning — the clinical picture (profuse sweating, excess salivation, laboured breathing/bronchospasm, pinpoint pupils/miosis, bradycardia, convulsions) is the classic muscarinic/CNS toxidrome of OP poisoning (SLUDGE syndrome)

Line of management

  • Maintain airway, breathing, circulation; give oxygen, suction secretions
  • Remove contaminated clothing, wash skin thoroughly to prevent further absorption
  • Gastric lavage if ingested and within a safe time window
  • Continuous cardiac and respiratory monitoring; assisted ventilation if needed
  • Treat convulsions with IV Diazepam

Specific antidotes and their usefulness

  • Atropine sulphate (IV, titrated until atropinisation): Competitively blocks muscarinic receptors, reversing bradycardia, excess secretions, and bronchospasm — does not reverse nicotinic (neuromuscular) effects
  • Pralidoxime (2-PAM) (IV): Reactivates acetylcholinesterase by removing the phosphate group from the enzyme-inhibitor complex, most effective if given early before “ageing” occurs — reverses both muscarinic and nicotinic effects, unlike atropine alone
