A farmer was suspected of some unknown substance poisoning, as he presented with bronchorrhoea, sweating and excessive salivation. Examination revealed bradycardia with bilateral miosis. Consider the following statements regarding his poisoning: 1. The symptoms represent Anti-Cholinergic Syndrome. 2. Activation of Acetylcholinesterase (AChE) enzyme is the underlying mechanism. 3. Intravenous Atropine should be given for treatment. Which of the statements given above is/are correct?
3 only
This presentation (bronchorrhoea, salivation, sweating, bradycardia, miosis) is the classic cholinergic (SLUDGE) syndrome of organophosphate poisoning, not an anticholinergic syndrome, so statement 1 is false. The mechanism is inhibition, not activation, of acetylcholinesterase, so statement 2 is false. IV Atropine is the correct first-line antidote, making only statement 3 correct.
