Clinical trials

This prospective, single-center, randomized controlled trial aims to compare remimazolam anesthesia with planned flumazenil reversal and sevoflurane-based balanced anesthesia in adult women undergoing ambulatory hysteroscopic surgery. Participants will be randomly assigned in a 1:1 ratio to receive either remimazolam for induction and maintenance followed by flumazenil reversal or propofol induction followed by sevoflurane-based balanced anesthesia. The primary outcome is anesthesia-controlled time, defined as the sum of induction time and emergence time. Secondary outcomes include recovery profiles, postoperative symptoms, quality of recovery, hemodynamic stability, and the incidence of re-sedation. The study will evaluate whether a remimazolam-flumazenil strategy can improve operating room efficiency while maintaining recovery quality and safety comparable to conventional sevoflurane-based anesthesia in the ambulatory surgery setting.

The purpose of this study is to compare the effects of remimazolam and propofol on postoperative recovery time, complications, and safety in patients undergoing ambulatory upper airway surgery under general anesthesia.
