What is the average duration of action for vecuronium?

15 - 30 minutes
30 - 45 minutes
45 - 60 minutes
60 - 75 minutes

The correct answer is: 30 - 45 minutes

Vecuronium is a neuromuscular blocking agent often used in anesthetic practice to induce muscle relaxation during surgical procedures. Its average duration of action typically falls within the range of 30 to 45 minutes. This duration makes vecuronium particularly useful for procedures that require muscle relaxation without a long-lasting effect, allowing for more rapid recovery of muscle function once the medication is discontinued. The pharmacokinetics of vecuronium indicate that it has a relatively moderate duration of action compared to other neuromuscular blockers. It is metabolized primarily by the liver and eliminated through the kidneys, and as a result, the duration of effect can vary based on factors such as the patient's metabolic state, age, and concomitant medications. Understanding the duration of action is crucial for transport nurses, as they need to manage and anticipate the patient's recovery from neuromuscular blockade and ensure appropriate ventilation support until the effects wear off.
