In the infant population, which of the following NMBA is an intermediate acting agent?

A. Atracurium

B. Rocuronium

C. Vecuronium

D. Pancuronium

Answer

The answer is A. Pancuronium is a long acting agent (>50 mins) in any population. While in adults and children rocuronium and vecuronium are intermediate acting agents (20-50 mins), in the infant population these agents have a consistently prolonged duration of action (making them long acting agents in this population). This is due to a longer residence time and a lower site concentration needed for effect (increased sensitivity) in the infant.
