Clinical Trial Summary

This prospective, randomized, single-blinded study is designed to compare the recovery profile between propofol-based total intravenous anesthesia (TIVA) and remimazolam-based TIVA in patients undergoing thyroidectomy. In the remimazolam group, its antagonist, flumazenil, is administered at the end of surgery. We hypothesize that remimazolam-based TIVA antagonized by flumazenil can significantly shorten the time from the end of anesthetic administration to eye-opening compared to propofol-based TIVA.

Description:

Adult patients undergoing elective thyroidectomy are randomly allocated to receive propofol-based TIVA (n=35) or remimazolam-based TIVA (n=35). The recovery profile including the time from the end of anesthetic administration to eye-opening, the time from the end of anesthetic administration to extubation, hemodynamic stability, stability of anesthetic depth, duration of post-anesthetic care stay, the incidence of postoperative nausea and vomiting during the first 24 hours, and the quality of recover 24 hours after surgery using the quality of recovery-15 was assessed by an investigator. The primary outcome is the time from the end of anesthetic administration to eye-opening.

Related Conditions & MeSH terms

• Anesthesia, Intravenous

Intervention

Drug:
• remimazolam-based TIVA
In the remimazolam-based TIVA group, general anesthesia is induced and maintained with a continuous infusion of remimazolam using an infusion pump. In the remimazolam group, its antagonist, flumazenil, is administered at the end of surgery.
• propofol-based TIVA
In the propofol-based TIVA group, general anesthesia is induced and maintained with a target-controlled infusion of propofol using an infusion pump (Orchestra®; Fresenius Vial, France).
