Comparison of dexmedetomidine and benzodiazepine for intraoperative sedation in elderly patients: a randomized clinical trial.

Background And Objectives: Elderly individuals have a greater sensitivity to sedation, and the most commonly used drugs for sedation are benzodiazepines, which exhibit some complication. Therefore, this study aimed to compare the use of dexmedetomidine and midazolam regarding proper sedation and postoperative complications in elderly individuals who require intraoperative sedation.

Methods: This study was a parallel-randomized clinical trial, which included 120 patients aged >70 years undergoing regional anesthesia and sedation.
