## 解决方案

1. ```
   If ingestion is within 2 hours, administer activated charcoal (1-2 g/kg orally) and immediately transport to vet for blood clotting time test (PT/PTT).
   ```
2. ```
   For confirmed anticoagulant poisoning, start vitamin K1 therapy: 5 mg/kg SC initially, then 2.5 mg/kg PO every 12 hours for 3-4 weeks, with weekly PT monitoring.
   ```
3. ```
   For severe bleeding, administer fresh frozen plasma (10-20 ml/kg IV) and vitamin K1; consider blood transfusion if PCV < 20%.
   ```

## 无效尝试

- **Induce vomiting immediately after ingestion** — Vomiting is ineffective for anticoagulant rodenticides as they absorb quickly; also risks aspiration if pet is already bleeding internally. (85% 失败率)
- **Give vitamin K1 only once** — Anticoagulant rodenticides require repeated vitamin K1 therapy for 3-4 weeks; a single dose is insufficient and bleeding resumes. (90% 失败率)
- **Use activated charcoal for all rodenticide types** — Activated charcoal is only effective within 1-2 hours of ingestion and does not neutralize absorbed toxins; also contraindicated for some bait formulations. (70% 失败率)
