Rationale
Organophosphate poisoning within Australia is uncommon. Life-saving treatment involves atropinisation and ventilation. A Cochrane review found insufficient evidence to support the routine use of pralidoxime. It may be associated with increased harm. Pralidoxime is rarely recommended by clinical toxicologists.
