The role of anxiolytic premedication in the ambulatory surgical population is frequently debated. Anesthesiologists may consider the administration of anxiety-reducing drugs unnecessary when anxiety levels are low in outpatients presenting for minor surgery. However, the previous study reports that up to 80% of outpatients expressed a preference for a combination of anxiety-reducing and hypnotic premedication before surgery (1-4). In addition to anxiolysis, goals of anxiolytic premedication include sedation, amnesia, improved patient cooperation, and/or improved patient satisfaction. Intravenous (IV) midazolam is the most commonly used premedicant in the ambulatory setting due to its rapid onset, and short half-life (2,3,5), but its residual effects in the immediate postoperative period may contribute to postoperative sedation, as well as to delayed recovery and discharge-readiness after brief outpatient surgery. Furthermore, White et al. (6) noted that the slope of the dose-response curve for sedation was much steeper with midazolam compared with diazepam, which suggests that midazolam may possess a smaller margin of safety and greater need for careful titration to achieve the desired clinical end-point without untoward side effects.
