Abstract
Remifentanil is a potent μ-opioid receptor agonist, and its onset and duration of action are very short. Its action disappears very quickly after ceasing infusion, and it is therefore thought to be useful in anesthetic management for day surgery. Because its plasma concentration can be easily controlled, remifentanil is suitable for awake intubation and insertion of a laryngeal mask airway. For these reasons, remifentanil is thought to be useful for the anesthetic management of orthopedic surgery.
