Which one of the following is the drug of choice in a child presenting with supraventricular tachycardia?
Drug of Choice for Pediatric Supraventricular Tachycardia
Supraventricular tachycardia (SVT) in children requires prompt and effective treatment. The primary goal is to restore a normal heart rhythm.
Pharmacological Treatment for SVT in Children
For stable SVT in pediatric patients, specific medications are considered the first line of treatment. Evaluating the options provided:
- Adenosine: This medication is the preferred agent for terminating stable SVT in children. It acts by transiently blocking the AV node, interrupting reentrant pathways. Its extremely short half-life (less than 10 seconds) makes it safe and effective, as its effects are quickly reversible.
- Atropine: Primarily used to treat symptomatic bradycardia, not typically indicated for SVT.
- Lidocaine: Generally used for ventricular arrhythmias, not the first-line treatment for SVT.
- Naloxone: An opioid antagonist used to reverse opioid overdose; it has no role in managing SVT.
Conclusion
Based on established pediatric advanced life support guidelines and pharmacological properties, Adenosine is the drug of choice for managing supraventricular tachycardia in a child presenting with a stable rhythm.
