Effect of combination of remimazolam and sevoflurane on elderly patients' recovery quality from general anesthesia after laparoscopic abdominal surgery: a randomized controlled trial.

Purpose: Remimazolam toluene sulfonic acid is a short-acting benzodiazepine primarily studied for intravenous anesthesia. To date, few studies have focused on the effects of the combination of remimazolam and inhalation anesthesia or its impact on postoperative recovery. Our study aims to investigate the influence of remimazolam combined with sevoflurane for general anesthesia maintenance on postoperative recovery quality in elderly patients undergoing laparoscopic abdominal surgery.
