    Area of Science:

    • Cardiology
    • Clinical Pharmacology
    • Pediatric Emergency Medicine

    Background:

    • Propranolol is a beta-blocker commonly prescribed for various cardiovascular conditions.
    • Overdosage of propranolol can lead to life-threatening toxicity, particularly in pediatric patients.
    • Understanding the clinical presentation and management strategies for propranolol toxicity is crucial for emergency care.

    Observation:

    • A 14-year-old male ingested a significant amount of propranolol (8000 mg).
    • The patient presented with acute onset of cardiac arrhythmias, heart failure, and seizures.
    • Clinical monitoring revealed severe cardiovascular compromise following the ingestion.

    Findings:

    • The overdose led to significant cardiac dysfunction and central nervous system effects.
    • Successful management involved a multi-modal approach including mechanical ventilation.
    • Transvenous pacing and high-dose isoprenaline administration were critical in stabilizing the patient's cardiac function.

    Implications:

    • This case highlights the potential severity of propranolol overdose even in adolescents.
    • Aggressive supportive care and targeted pharmacological interventions are essential for survival.
    • The case underscores the importance of prompt recognition and management of beta-blocker toxicity in emergency settings.
