Rodenticide Toxicity
Ayrıca bilinen adıyla: Rodenticide Intoxication, Rodenticide Poisoning, Anticoagulant Rodenticide Toxicity
Kısaca
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.

Nedir?
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).
Nedenler ve risk faktörleri
Direct bait ingestion; cats also secondary poisoning via prey. Dogs often indiscriminate eaters. Consider blood types if transfusion needed (type B cats).
Belirtiler
- 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)

Veterinerler nasıl tanır
Identify active ingredient from packaging. PT/aPTT, PIVKA, anticoagulant screen, CBC, blood gas, thoracic/abdominal imaging for internal bleeding.

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