A case of 'superwarfarin' poisoning
Scandinavian Journal of Haematology
|March 1, 1986
Summary
A young adult experienced prolonged bleeding for over six months after ingesting a potent rodenticide, brodifacoum. High doses of vitamin K1 were required to treat this severe superwarfarin poisoning.
Area of Science:
- Toxicology
- Pharmacology
- Emergency Medicine
Background:
- Brodifacoum is a highly potent anticoagulant rodenticide.
- Superwarfarin compounds pose significant poisoning risks due to their long half-lives.
- Intentional ingestion can lead to severe, life-threatening complications.
Observation:
- A young adult intentionally ingested 10 mg of brodifacoum.
- The patient presented with prolonged and severe bleeding episodes.
- Bleeding persisted for an extended duration, exceeding six months.
Findings:
- The case highlights the extreme toxicity and prolonged action of brodifacoum.
- Standard anticoagulant reversal protocols may be insufficient.
- Vitamin K1 therapy required high doses and extended administration.
Implications:
- Clinicians must be aware of the prolonged and severe coagulopathy caused by superwarfarins.
- Management requires aggressive and prolonged vitamin K1 supplementation.
- This case underscores the critical need for prompt and intensive treatment in superwarfarin poisoning.
