easy · MCQ · Q-12A1EA

A 35-year-old male is scheduled for an emergency exploratory laparotomy. Rapid sequence intubation (RSI) is planned. Which of the following neuromuscular blocking agents has the fastest onset of action at standard intubating doses?

  1. A.Atracurium
  2. B.SuccinylcholineCorrect answer
  3. C.Rocuronium
  4. D.Vecuronium

Solution

Succinylcholine is a depolarizing neuromuscular blocker with the fastest onset of action (approximately 30 to 60 seconds) among all muscle relaxants, making it ideal for rapid sequence induction. Rocuronium is the fastest among non-depolarizing agents (60 to 90 seconds), but still slower than succinylcholine.
