Rodenticide Toxicity
Aussi appelé: Rodenticide Intoxication, Rodenticide Poisoning, Anticoagulant Rodenticide Toxicity
En bref
Rodenticide poisoning is a common and life-threatening veterinary emergency that occurs when pets ingest rat or mouse bait, leading to severe internal bleeding, neurological damage, or organ failure depending on the chemical involved. Immediate veterinary intervention is critical for survival.
TL;DR. Urgence vitale: hémorragie, neuro ou organes selon le toxique.
Appâts attractifs.
Qu'est-ce que c'est ?
Chemical baits against rats/mice. Classes: anticoagulants (vitamin K block and coagulopathy), bromethalin (neurotoxin, cerebral edema), cholecalciferol (hypercalcemia, renal failure), zinc phosphide (phosphine gas), strychnine (muscle rigidity).
Causes et facteurs de risque
Direct bait ingestion; cats also secondary poisoning via prey. Dogs often indiscriminate eaters. Consider blood types if transfusion needed.
Signes à surveiller
- Hemorrhage (cardinal for anticoagulants): epistaxis, hematuria, melena, petechiae (often 2-5 days after ingestion)
- Lethargy, pale mucous membranes, anemia, vomiting (common)
- Respiratory distress, ataxia, tremors/seizures, rigidity, polyuria/polydipsia (toxin-dependent)
Gencives pâles: perte de sang.
Comment les vétérinaires diagnostiquent
Identify active ingredient from packaging. PT/aPTT, PIVKA, anticoagulant screen, CBC, blood gas, thoracic/abdominal imaging for internal bleeding.
Radio thorax: hémorragie interne.
Options de traitement
Early: emesis (e.g. Apomorphine in dogs), Activated Charcoal. Anticoagulants: Phytonadione (vitamin K1) for weeks. Support: oxygen, plasma/blood transfusion. Neurotoxins and cholecalciferol: aggressive support, poorer prognosis.
Pronostic
Anticoagulants: excellent with early decontamination before bleeding; guarded with severe internal hemorrhage. Bromethalin/phosphide/cholecalciferol: guarded to poor after clinical signs.
Prévention
Prefer traps; secure bait stations only; keep packaging/photo of ingredients; limit hunting of wild rodents.
Quand appeler le vétérinaire
Level-5 emergency. Known/suspected ingestion, captured rodent in baited areas, unexplained bleeding, tremors/seizures: now.
