A 4-year-old in pulseless VT requires defibrillation and medication. What is the correct dose of amiodarone for pediatric VF/pulseless VT?
Answer: 5 mg/kg IV/IO
Amiodarone for pediatric VF/pulseless VT is 5 mg/kg IV/IO (maximum 300 mg per dose).
Which vasopressor is considered first-line for anaphylaxis in the pediatric patient?
Answer: Epinephrine
Epinephrine (IM into anterolateral thigh) is the first-line treatment for anaphylaxis in all age groups.
A 6-year-old with symptomatic bradycardia does not respond to oxygenation and ventilation. What is the first medication given?
Answer: Atropine
Atropine 0.02 mg/kg IV/IO is the first-line drug for symptomatic bradycardia after oxygenation/ventilation fails.
What is the minimum dose of atropine recommended in PALS to avoid a paradoxical bradycardic effect?
Answer: 0.1 mg
The minimum atropine dose in PALS is 0.1 mg to prevent paradoxical bradycardia from excessive muscarinic stimulation at very low doses.
Which drug is indicated for torsades de pointes in a pediatric patient?
Answer: Magnesium sulfate
Magnesium sulfate 25–50 mg/kg IV/IO is the treatment of choice for torsades de pointes in children.
A child with SVT weighing 20 kg receives adenosine. The correct initial dose is:
Answer: 0.1 mg/kg (2 mg) rapid IV push
The initial adenosine dose is 0.1 mg/kg (maximum 6 mg) given as a rapid IV push followed by a NS flush.
Sodium bicarbonate may be considered in pediatric arrest for which specific condition?
Answer: Hyperkalemia-induced cardiac arrest
Sodium bicarbonate is considered in cardiac arrest associated with hyperkalemia or sodium-channel blocker toxicity.
