What is the Rocuronium dose for adult post‑intubation sedation/paralysis?

• A. 0.5 mg/kg IV/IO
• B. 0.75 mg/kg IV/IO
• C. 1 mg/kg IV/IO (Minimum dose: 50 mg; Maximum dose: 100 mg)
• D. 2 mg/kg IV/IO

Answer: (C)

Rocuronium is given at 1 mg/kg IV/IO for adult post-intubation paralysis to achieve rapid, reliable neuromuscular blockade. This dose typically produces onset within about a minute, which is crucial after intubation to secure the airway and allow controlled ventilation. Lower doses, like 0.5 or 0.75 mg/kg, can still paralyze muscles but have slower, less predictable onset, increasing the risk that the patient moves or that ventilation isn’t optimal while waiting for the block. The dosing is bounded for practical safety: a minimum of 50 mg ensures smaller adults receive enough drug for effective blockade, while a maximum of 100 mg helps prevent overdosing in larger adults and reduces the chance of prolonged blockade. If deeper or sustained paralysis is needed beyond the initial bolus, clinicians may repeat dosing or use a protocol-guided infusion as appropriate.
