During pediatric advanced airway Induction for Airway Control, which induction agent is used for rapid onset?

• A. Etomidate 0.3 mg/kg IV/IO RAPID (1 Dose)
• B. Ketamine 1 mg/kg IV/IO RAPID
• C. Propofol 1 mg/kg IV/IO RAPID
• D. Succinylcholine 1 mg/kg IV

Answer: (A)

The main idea is choosing an induction agent that renders the patient unconscious quickly while keeping the heart and lungs stable enough for a safe airway procedure. Etomidate at 0.3 mg/kg given IV or IO acts very fast, typically producing loss of consciousness within seconds, and it does so with minimal impact on heart rate and blood pressure. It also tends to preserve spontaneous breathing, which can be advantageous during airway control in kids because it reduces the risk if the airway is difficult and ventilation becomes challenging. That combination—rapid onset plus stable hemodynamics and relatively gentle respiratory effects—makes it the preferred option for rapid induction in pediatric airway management. Propofol, while fast-acting, is more likely to cause significant drops in blood pressure and stronger respiratory depression, which can complicate securing the airway. Ketamine does provide rapid onset and preserves airway reflexes, but it raises heart rate and blood pressure and can increase secretions, which may complicate airway management in some children. Succinylcholine is a quick-acting muscle relaxant used to facilitate intubation, but it does not by itself provide anesthesia, so it’s not an induction agent.
