Life-threatening organophosphate-induced delayed polyneuropathy in a child after accidental chlorpyrifos ingestion. 
Life-threatening organophosphate-induced delayed polyneuropathy with transient bilateral vocal cord paralysis occurred in a 3-year-old child.  Recovery was slow after prolonged ventilatory support.  Patients who recover from serious organophosphate intoxications should be closely monitored for the development of organophosphate-induced delayed polyneuropathy.
