Remimazolam Versus Propopol Based Total Intravenous Anesthesia for Breast Surgery
- Registration Number
- NCT05375747
- Lead Sponsor
- Seoul National University Hospital
- Brief Summary
Comparison of the incidence of hypotension under remimazolam and propofol-based anesthesia in patients undergoing breast surgery under general anesthesia
- Detailed Description
The purpose of this study was to investigate whether remimazolam-based general anesthesia could reduce the incidence of hypotension in patients undergoing breast surgery under general anesthesia compared to propofol-based general anesthesia. The purpose of this study is to establish and test the hypothesis that the incidence of hypotension under general anesthesia based on remimazolam will be less than that of propofol based general anesthesia. In addition, this study compares the proportion of patients who require a vasopressor, the time taken for anesthesia induction, the time to recover from anesthesia, postoperative pain, the incidence of postoperative nausea and vomiting, the quality of postoperative recovery, and patient satisfaction.

Group Intervention Description Propofol based total intravenous anesthesia Propofol For induction and maintenance of anesthesia, total intravenous anesthesia is performed using continuous intravenous infusion of propofol and remifentanil. Remimazolam based total intravenous anesthesia Remimazolam For induction and maintenance of anesthesia, total intravenous anesthesia is performed using continuous intravenous infusion of remimazolam and remifentanil.
