Rocuronium is used after succinylcholine to maintain paralysis. What is the typical RSI dose of Rocuronium?

• A. 0.5 mg/kg
• B. 2 mg/kg
• C. 0.25 mg/kg
• D. 1 mg/kg

Answer: (D)

In RSI, you want rapid, reliable muscle relaxation to allow a smooth, safe intubation window after induction. After giving a brief depolarizing agent for quick onset, rocuronium is used to sustain paralysis long enough to complete airway placement. The typical RSI dose of rocuronium is 1 mg/kg IV. This amount provides workable intubating conditions within about a minute and offers a block that lasts long enough (roughly 30–60 minutes) to cover the initial airway management without needing an immediate reversal. Lower doses may not maintain adequate relaxation, while higher doses prolong the blockade more than necessary and can complicate subsequent management if rapid reversal is required.
