Summary
Activated charcoal therapy can cause serious harm if not used carefully. Key risks include aspiration, gastrointestinal obstruction, and electrolyte imbalances, necessitating judicious dosing and patient monitoring for safe use.
Area of Science:
- Medical Toxicology
- Emergency Medicine
- Pharmacology
Background:
- Activated charcoal is widely used for poisoning treatment.
- Potential adverse effects can occur with its administration.
- Understanding these risks is crucial for patient safety.
Purpose of the Study:
- To review adverse effects of activated charcoal therapy.
- To provide recommendations for safe administration.
- To minimize morbidity and mortality associated with its use.
Main Methods:
- Manual literature search of Index Medicus (1970-1993).
- Inclusion of detailed case reports with significant morbidity/mortality.
- Bibliographic scanning of relevant articles.
Main Results:
- Major causes of harm: aspiration, GI obstruction, electrolyte abnormalities.
- Aspiration linked to unprotected airways and improper dosing/dilution.
- Obstruction associated with multiple doses without cathartics or impaired peristalsis.
Conclusions:
- Judicious use of activated charcoal is vital to prevent adverse events.
- Patient airway protection, appropriate dosing, and cathartic use are critical.
- Monitoring fluid/electrolyte status and clinical condition ensures safe therapy.
