Summary
Severe acute digoxin poisoning is predicted by vomiting, hyperkalemia, and bradycardia. A fatal outcome is more likely in patients over 65 with existing conditions, vomiting, and bradycardia.
Area of Science:
- Cardiology
- Clinical Toxicology
- Pharmacology
Context:
- Acute digoxin overdose presents significant electric instability and a notable mortality rate.
- Identifying risk factors for severe digoxin intoxication is crucial for timely intervention.
- This study retrospectively analyzed 50 cases of acute digoxin poisoning over eight years.
Purpose:
- To identify predictive risk factors for severe acute digoxin intoxication.
- To determine factors associated with a fatal outcome in digoxin overdose cases.
Summary:
- Severe poisoning (PSS 3-4) was associated with hyperkalemia, bradycardia, and vomiting.
- Risk of severe poisoning increased with hyperkalemia, bradycardia, vomiting, age over 65, and digoxin dose over 10 mg.
- Fatal outcomes were linked to age over 65 with comorbidities, vomiting, and bradycardia.
Impact:
- This research provides critical insights into predicting severe digoxin toxicity.
- The findings can aid clinicians in risk stratification and management of digoxin overdose patients.
- Early identification of these risk factors can potentially reduce mortality associated with digoxin poisoning.
