What is the paralytic dose for pediatric airway control?

• A. Rocuronium 0.5 mg/kg
• B. Succinylcholine 1 mg/kg
• C. Rocuronium 1 mg/kg
• D. Vecuronium 0.1 mg/kg

Answer: (C)

In pediatric airway control, you want a paralytic that acts quickly and predictably to allow rapid and safe intubation. Rocuronium given at 1 mg/kg achieves rapid onset of neuromuscular blockade—typically around a minute—providing reliable intubating conditions in children. This rapid effect with a favorable safety profile makes it the preferred choice for urgent airway control. Lower doses of rocuronium would delay onset and might not provide adequate conditions in time, while a very small dose of another agent like vecuronium is too slow for urgent airway access. Succinylcholine at 1 mg/kg is also fast, but it carries higher risks in pediatric patients (such as hyperkalemia, bradycardia, and malignant hyperthermia) and is avoided in many protocols, which is why rocuronium at 1 mg/kg is considered the best option here.
