Rodenticide Toxicity
Juga dikenali sebagai: Rodenticide Intoxication, Rodenticide Poisoning, Anticoagulant Rodenticide Toxicity
Ringkasnya
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. Kecemasan mengancam nyawa: pendarahan atau kegagalan organ mengikut toksin.

Apakah itu?
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).
Punca dan faktor risiko
Direct bait ingestion; cats also secondary poisoning via prey. Dogs often indiscriminate eaters. Consider blood types if transfusion needed (type B cats).
Tanda yang perlu diperhatikan
- 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)

Bagaimana doktor haiwan mendiagnosis
Identify active ingredient from packaging. PT/aPTT, PIVKA, anticoagulant screen, CBC, blood gas, thoracic/abdominal imaging for internal bleeding.

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