Nerve agent toxicity and treatment

Opinion statement

  • The clinical syndrome of nerve agent toxicity varies widely, ranging from the classic cholinergic syndrome to flaccid paralysis and status epilepticus.

  • All nerve agents are capable of producing marked neuropathology. Seizure control is strongly associated with protection against acute lethality and brain pathology.

  • The mainstays of therapy of nerve agent poisoned patients are atropine, pralidoxime, and benzodiazepines.

  • Fosphenytoin provides little therapeutic anticonvulsant effectiveness for nerve agent-induced status epilepticus.

  • Tachycardia is not a contraindication to treatment with atropine in nerve agent toxicity.

  • Atropine should be administered to alleviate respiratory distress, symptomatic bradycardia, and as an adjunct to benzodiazepines and pralidoxime to alleviate seizure activity.

  • In significant nerve agent toxicity, a continuous pralidoxime infusion may be considered.

This study indicates that a loading dose followed by a continuous infusion of pralidoxime maintains therapeutic concentrations for a longer period of time than the historically recommended intermittent bolus infusion method.

Midazolam was the most potent and rapidly acting benzodiazepine.
