Insights
Rivastigmine poisoning in a child caused a severe cholinergic syndrome requiring intensive care. Prompt recognition and management of its toxic effects, including cardiac complications, are crucial for survival.
Area of Science:
- Toxicology
- Pediatric Emergency Medicine
- Clinical Pharmacology
Background:
- Rivastigmine, an acetylcholinesterase inhibitor, is used to treat dementia.
- Poisoning can lead to a severe cholinergic syndrome with nicotinic, muscarinic, and central nervous system effects.
Observation:
- A 3-year-old girl ingested rivastigmine, presenting with altered mental status, sialorrhea, sweating, diarrhea, and respiratory failure.
- She developed significant gastrointestinal distress and frequent ventricular ectopic beats, indicating cardiac involvement.
- Follow-up revealed a transient cardiac dysrhythmia.
Findings:
- Cholinergic syndrome from rivastigmine poisoning can be life-threatening in pediatric patients.
- The case highlights the need for intensive care and supportive management for severe poisoning.
- Cardiac complications, such as dysrhythmias, can occur and require careful monitoring.
Implications:
- Early identification and management of rivastigmine toxicity are essential for patient outcomes.
- Assessment for cardiac complications is critical in patients with cholinergic syndrome due to poisoning.
- Autonomic dysfunction, hypoxemia, acidosis, and electrolyte imbalances are key factors predisposing to complications.
Background:
We report a case of rivastigmine poisoning resulting in a full cholinergic syndrome with nicotinic, muscarinic, and central effects requiring supportive or intensive care in a pediatric patient.
Case Report:
A 3-year-old girl was admitted to the Emergency Department suspected of having ingested one or two pills of rivastigmine. The child was hyporeactive, with symptoms of altered mental status, sialorrhea, sweating, and diarrhea. Subsequently, she started showing signs of respiratory failure, severe tracheobronchial involvement, and gastric and abdominal distension. An electrocardiogram recorded frequent monomorphic ventricular ectopic beats with bigeminy and trigeminy. Long-term follow-up showed a transient dysrhythmia.
Conclusion:
Poisoning with rivastigmine can be a life-threatening condition. Timely identification and appropriate management of the toxic effects of this drug are essential and often life-saving. This is particularly true in cases of cholinergic syndrome subsequent to drug poisoning. Patients with cholinergic syndrome should also be assessed for possible cardiac complications such as dysrhythmias. The main factors predisposing to the development of such complications are autonomic disorder, hypoxemia, acidosis, and electrolyte imbalance.
