This prospective randomized trial aims to compare recovery time from discontinuation of remimazolam followed by flumazenil administration vs. propofol-based total intravenous anesthesia in patients undergoing breast cancer surgery.
Adult patients undergoing breast cancer surgery are randomized to receive either remimazolam with flumazenil or propofol-based total intravenous anesthesia. When the surgery is ended, anesthetic agents are discontinued. The study's primary outcome is a comparison of the time to the first eye-opening response to the doctor's command from the discontinuation of anesthetic agents between the groups. Secondary outcomes include the time from anesthetics off to extubation/discharge from operating room (OR), BIS score at eye-opening/extubation/discharge from OR, the incidence of emergence agitation at OR, the PAT score, the modified Aldrete score, modified OAA/S (Observers Assessment of Alertness/Sedation Scale) after PACU administration. In addition, the investigators investigate postoperative pain score at 10/20/30 minutes and postoperative nausea and vomiting after PACU administration, Korean version of quality of recovery-15 in postoperative 24 hours, postoperative pain score and postoperative nausea and vomiting, postoperative opioid consumption in postoperative 24 hours.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Remimazolam with flumazenil | Experimental | Patients allocated to remimazolam with flumazenil group receive remimazolam as the main anesthetics during general anesthesia and then flumazenil administration at the end of anesthesia. Remifentanil continuous infusion can be used for hemodynamic stability and analgesia. |
|
| Propofol-based total intravenous anesthesia | Active Comparator | Patients allocated to the propofol-based total intravenous anesthesia group receive propofol as the main anesthetics during general anesthesia until the end of anesthesia. Remifentanil continuous infusion can be used for hemodynamic stability and analgesia. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| REMIMAZOLAM BESYLATE 2.5 Mg in 1 mL INTRAVENOUS INJECTION, POWDER, LYOPHILIZED, for SOLUTION [BYFAVO] | Drug | Remimazolam Besylate is used as an intervention drug for general anesthesia, followed by flumazenil administration at the end of anesthesia, compared to propofol-based total intravenous anesthesia during breast cancer surgery under general anesthesia |
| Measure | Description | Time Frame |
|---|---|---|
| Time to eye opening (minute) | The time to the first eye-opening response to the doctor's command from the discontinuation of anesthetic agents | 20 minutes after anesthesia emergence |
| Measure | Description | Time Frame |
|---|---|---|
| Time to emergence (minutes) | The time from anesthetics off to extubation/discharge from operating room | 20 minutes after anesthesia emergence |
| Bispectral index score (Score) | A BIS score quantifies changes in the electrophysiologic state of the brain during anesthesia. In patients who are awake, a typical BIS score is 90 to 100. Complete suppression of cortical activity results in a BIS score of 0, known as a flat line. Lower numbers indicate a higher hypnotic effect. |
