What is the treatment of OP poisoning?
The mainstays of medical therapy in organophosphate (OP) poisoning include atropine, pralidoxime (2-PAM), and benzodiazepines (eg, diazepam). Initial management must focus on adequate use of atropine. Optimizing oxygenation prior to the use of atropine is recommended to minimize the potential for dysrhythmias.
When do you give atropine in OP poisoning?

Atropine (LB) If these targets are not achieved by 3-5 minutes, double the intravenous dose. Continue to double the dose and give intravenously every 3-5 minutes until atropinisation has been achieved. Some patients may require large doses (hundreds of mg).
How is OP poisoning diagnosed?
The diagnosis of OP poisoning is made on the basis of history of poisoning, smell of pesticides, the characteristic clinical signs and reduced cholinesterase activity. Measurement of plasma cholinesterase is useful for diagnosis of OP poisoning although it may not directly correlate with severity of the poisoning.

What happens to cholinesterase in OP poisoning?
Organophosphate Poisoning At a Glance Organophosphates inhibit cholinesterase enzymes, including red blood cell (RBC) cholinesterase and plasma cholinesterase, thereby preventing the breakdown of acetylcholine.
