Rodenticide Toxicity
Tunnetaan myös nimellä: Rodenticide Intoxication, Rodenticide Poisoning, Anticoagulant Rodenticide Toxicity
Lyhyesti
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. Hengenvaarallinen hata: verenvuoto tai elinvaurio toksiinista riippuen.
Syotit houkuttelevat tuholaisia ja uteliaita lemmikkeja.
Mikä se on?
Chemical baits against rats/mice. Classes: anticoagulants (vitamin K block; coagulopathy), bromethalin (neurotoxin; cerebral edema), cholecalciferol (hypercalcemia; renal failure), zinc phosphide (phosphine gas), strychnine (muscle rigidity).
Syyt ja riskitekijät
Direct bait ingestion; cats also secondary poisoning via prey. Dogs often indiscriminate eaters. Consider blood types if transfusion needed (type B cats).
Oireet
- 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, PU/PD (toxin-dependent)
Kalpeat limakalvot viittaavat vakavaan verenhukkaan.
Miten eläinlääkärit diagnosoivat
Identify active ingredient from packaging. PT/aPTT, PIVKA, anticoagulant screen, CBC, blood gas, thoracic/abdominal imaging for internal bleeding.

Hoito
Early emesis (e.g. Apomorphine in dogs), Activated Charcoal. Anticoagulants: Phytonadione (vitamin K1) for weeks. Support: oxygen, plasma/blood transfusion.
Ennuste
Anticoagulants: excellent with early decontamination before bleeding; guarded with severe internal hemorrhage. Bromethalin/phosphide/cholecalciferol: guarded to poor after clinical signs.
Ehkäisy
Prefer traps; secure baits in stations only; keep packaging/photos of ingredients; limit hunting of rodents.
Milloin soittaa eläinlääkärille
Grade-5 emergency. Known/suspected ingestion, captured rodent in bait areas, unexplained bleeding, tremors/seizures: go now.
