What is the management for pesticide poisoning?

Management of Chlorantraniliprole 18.5 Poisoning

Chlorantraniliprole poisoning should be managed with supportive care, as there is no specific antidote for this pesticide. The management focuses on decontamination, monitoring, and treating symptoms as they arise.

Initial Assessment and Management

• Ensure airway, breathing, and circulation - Standard resuscitation protocols apply
• Decontamination:
  • Remove contaminated clothing immediately
  • Wash skin thoroughly with large volumes of water and soap 1
  • For eye exposure, irrigate with copious amounts of water for at least 15 minutes

Specific Management Steps

1. Dermal decontamination: Perform while wearing protective equipment to prevent secondary contamination of healthcare providers 2

   • Use soap and water for thorough skin cleansing
   • Shampoo hair if contaminated

2. Gastric decontamination (if ingestion occurred within 60 minutes):

   • Consider activated charcoal (1 g/kg) with a cathartic 1, 3
   • Gastric lavage may be indicated if presenting within 60 minutes of ingestion 3

3. Supportive care:

   • Monitor vital signs, oxygen saturation, and mental status
   • Provide supplemental oxygen if needed
   • Maintain hydration with IV fluids
   • Monitor for respiratory depression and provide ventilatory support if necessary

Monitoring and Follow-up

• Continuous cardiac monitoring for at least 24-36 hours post-exposure 1
• Regular assessment of vital signs and mental status
• Monitor for delayed symptoms, particularly respiratory issues
• Laboratory tests: Complete blood count, electrolytes, liver and kidney function tests

Clinical Considerations

• Chlorantraniliprole has relatively low mammalian toxicity compared to organophosphate pesticides 4, 5
• Unlike organophosphates, chlorantraniliprole does not inhibit acetylcholinesterase, so atropine and pralidoxime are not indicated 2
• The primary mechanism of action is ryanodine receptor modulation in insects, with much lower affinity for mammalian receptors

Special Populations

• Children: May be more susceptible due to higher minute ventilation and lower body mass 2

  • Adjust activated charcoal dosing appropriately
  • Monitor more closely for respiratory depression

• Pregnant women: Management principles remain the same, with special consideration for the pregnancy status 1

Disposition

• Patients should be observed until asymptomatic and all vital signs have normalized
• Ensure source of poisoning is eliminated before discharge 1
• Patient education regarding safe handling of pesticides and prevention of future exposures

Prevention Recommendations

• Proper storage of pesticides away from children and food
• Use of appropriate personal protective equipment when handling
• Consideration of less toxic alternatives in agricultural and residential settings 2

While chlorantraniliprole has lower acute toxicity than many other pesticides, particularly organophosphates, poisoning should still be taken seriously with appropriate decontamination and supportive care measures.
