How is symptomatic bradycardia with poor perfusion managed in pediatric resuscitation?

• A. Only observe and repeat vitals in 5 minutes
• B. Treat reversible causes, provide oxygen and ventilation; consider atropine 0.02 mg/kg IV/IO (min 0.1 mg, max per dose 0.5 mg); escalate to pacing
• C. Immediate defibrillation
• D. Ignore bradycardia if perfusion poor

Answer: (B)

In pediatric resuscitation, symptomatic bradycardia with poor perfusion requires active management that combines treating reversible problems with supporting oxygenation and circulation. Start by ensuring the airway is open and provide high‑flow oxygen and ventilation as needed, because improving oxygen delivery helps correct bradycardia and perfusion. At the same time, identify and correct reversible factors such as hypoxia, electrolyte disturbances, electrolyte or toxin issues, and other causes of reduced heart rate. If the patient remains unstable, administer atropine at 0.02 mg/kg IV/IO, with a minimum of 0.1 mg and a maximum per dose of 0.5 mg, and repeat every 3–5 minutes if perfusion does not improve. If bradycardia persists despite atropine, escalate to pacing—transcutaneous pacing is the next step, with consideration of transvenous pacing as needed. This approach balances rapid symptom relief with addressing the underlying causes; observation, defibrillation, or ignoring the bradycardia do not provide the necessary treatment for a child with poor perfusion.
