What is the treatment for a 10-year-old with rodenticide (rat killer powder) poisoning?

Treatment for Rat Killer Powder Poisoning in a 10-Year-Old Child

In case of rat killer powder poisoning in a 10-year-old child, immediately contact the Poison Control Center (800-222-1222 in the US) and seek emergency medical care. 1

Initial Assessment and Management

1. Determine the type of rodenticide

   • Most common types:
     • Anticoagulant rodenticides (warfarin, brodifacoum, bromadiolone)
     • Bromethalin (neurotoxic)
   • Identify the specific product if possible to guide treatment

2. Immediate actions:

   • Activate emergency medical services (EMS) if the child shows any signs of:
     • Sleepiness
     • Seizures
     • Difficulty breathing
     • Vomiting 1
   • Do NOT administer anything by mouth (including water or milk) unless specifically advised by poison control or emergency medical personnel 1
   • Do NOT induce vomiting with syrup of ipecac as this can cause intractable emesis and delay care 1

Treatment Based on Rodenticide Type

For Anticoagulant Rodenticides (most common)

1. Assessment:

   • Monitor International Normalized Ratio (INR) 36-48 hours post-exposure 2
   • Watch for signs of bleeding: epistaxis, gingival bleeding, bruising, hematomas, hematuria, gastrointestinal bleeding

2. Treatment protocol:

   • If INR is normal at 48 hours, no further action is required 2
   • If INR ≥4.0 without active bleeding: administer vitamin K1 (phytomenadione) 2
   • If active bleeding occurs:
     • Administer prothrombin complex concentrate (50 units/kg) or
     • Fresh frozen plasma (15 mL/kg) if concentrate unavailable
     • Vitamin K1 (phytomenadione) 100 μg/kg intravenously 2

For Bromethalin Rodenticides

1. Assessment:

   • Monitor for neurological symptoms (seizures, tremors, weakness)
   • Note: Pediatric exposures rarely result in serious effects - studies show 96.38% of pediatric exposures had no effects, and no major clinical effects or deaths were reported 3

2. Treatment:

   • Supportive care
   • No specific antidote available 3
   • Manage seizures if they occur

Decontamination Procedures

1. If powder is on skin/clothing:

   • Brush powdered chemicals off the skin with a gloved hand or cloth
   • Remove all contaminated clothing
   • Thoroughly wash affected areas with copious amounts of water 1

2. If exposure to eyes:

   • Rinse eyes immediately with copious amounts of water 1

3. For ingestion:

   • Do NOT administer activated charcoal unless advised by poison control or emergency medical personnel 1

Important Considerations

• The majority of pediatric exposures to rodenticides result in minimal or no toxicity, but prompt medical evaluation is still essential
• Long-acting anticoagulant rodenticides can cause prolonged anticoagulation lasting weeks to months 2
• Follow-up monitoring may be necessary depending on the specific rodenticide involved

Prevention of Future Exposures

• Store rodenticides in locked cabinets out of reach of children
• Use tamper-resistant bait stations
• Consider safer packaging and appearance of rodenticides to prevent children from mistaking them for food 4

Remember that poison control centers are excellent resources for specific guidance based on the exact product ingested and the child's symptoms.
