Comparison of Recovery From General Anesthesia in Remimazolam With Flumazenil vs. Propofol

Registration Number
NCT05435911
Lead Sponsor
Seoul National University Hospital
Brief Summary

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.

Detailed Description

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.

Remimazolam with flumazenilREMIMAZOLAM BESYLATE 2.5 Mg in 1 mL INTRAVENOUS INJECTION, POWDER, LYOPHILIZED, for SOLUTION [BYFAVO]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.
Remimazolam with flumazenilFlumazenilPatients 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 anesthesiaPropofolPatients 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.
Primary Outcome Measures
NameTimeMethod
Time to eye opening (minute)20 minutes after anesthesia emergence

The time to the first eye-opening response to the doctor's command from the discontinuation of anesthetic agents

Secondary Outcome Measures
NameTimeMethod
Incidence of emergence agitation at operating room (n(%))Time Frame: 20 minutes after anesthesia emergence

Ricker sedation agitated scale ≥5 was defined as emergence agitation, (1-7)

The modified Observers Assessment of Alertness/Sedation Scale (Score)30 minutes after post anaestheisa care unit adminstration

The modified Observers Assessment of Alertness/Sedation Scale (0-5), Score 5 was defined as respond readily to name spoken in normal tone.

Postoperative Pain (score)upto 24 hours

Numerical rating scales score (0-10) of pain, The higher score was defined as severe pain

Postoperative opioid consumption (The number of analgesic use)upto 24 hours

Postoperative opioid requirement

Bispectral index score (Score)During 20 minutes after anesthesia emergence (3 point : Time from anesthetics off to eye opening/extubation/discharge from operating room)

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.

The modified Aldrete score (Score)30 minutes after post anaestheisa care unit adminstration

The modified Aldrete score (0-10), Score ≥9 was defined as the possibility of discharge from PACU

Time to emergence (minutes)20 minutes after anesthesia emergence

The time from anesthetics off to extubation/discharge from operating room

Postoperative nausea and vomiting (The incidence of PONV, n(%))from post anaestheisa care unit administation to post anaestheisa care unit discharge (during 30-40 minutes, upto 1 hours)

Postoperative nausea and vomiting

Postoperative quality of recovery (score)upto 24 hours

Korean version of quality of recovery-15, The higher score was defined as good satisfaction.
