Rodenticide Toxicity
Nota anche come: Rodenticide Intoxication, Rodenticide Poisoning, Anticoagulant Rodenticide Toxicity
In breve
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. Emergenza vitale: emorragia o danno d organo secondo il tossico.

Cos'è?
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).
Cause e fattori di rischio
Direct bait ingestion; cats also secondary poisoning via prey. Dogs often indiscriminate eaters. Consider blood types if transfusion needed (type B cats).
Segni da osservare
- 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)
Mucose pallide segnalano grave perdita di sangue.
Come diagnosticano i veterinari
Identify active ingredient from packaging. PT/aPTT, PIVKA, anticoagulant screen, CBC, blood gas, thoracic/abdominal imaging for internal bleeding.
Radiografie toraciche aiutano a individuare sanguinamento interno.
Opzioni di trattamento
Early emesis (e.g. Apomorphine in dogs), Activated Charcoal. Anticoagulants: Phytonadione (vitamin K1) for weeks. Support: oxygen, plasma/blood transfusion.
Prognosi
Anticoagulants: excellent with early decontamination before bleeding; guarded with severe internal hemorrhage. Bromethalin/phosphide/cholecalciferol: guarded to poor after clinical signs.
Prevenzione
Prefer traps; secure baits in stations only; keep packaging/photos of ingredients; limit hunting of rodents.
Quando chiamare il veterinario
Grade-5 emergency. Known/suspected ingestion, captured rodent in bait areas, unexplained bleeding, tremors/seizures: go now.
