Trial summary

The investigators hypothesized that intraoperative opioid consumption would be different between remimazolam and propofol if the ANI-guided remifentanil continuous infusion rate was adjusted when the depth of anesthesia was maintained at similar depths with remimazolam or propofol under total intravenous anesthesia.

About this study

Official title: Comparison of Intraoperative Remifentanil Requirements During Remimazolam Versus Propofol Total Intravenous Anesthesia With Analgesia Nociception Index-guided Remifentanil Administration: a Randomized Controlled Study

The investigators hypothesized that intraoperative opioid consumption would be different between remimazolam and propofol if the ANI-guided remifentanil continuous infusion rate was adjusted when the depth of anesthesia was maintained at similar depths with remimazolam or propofol under total intravenous anesthesia. The purpose of this study is to compare the intraoperative remifentanil requirement in patients undergoing total knee arthroplasty when the intraoperative remifentanil dose adjustment was performed under the ANI guidance while maintaining a similar depth of anesthesia with remimazolam or propofol.

Being tested
remimazolam group, propofol group

Osteoarthritis, Knee

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • remimazolam groupDrug

    Remimazolam 6 mg/kg/hr is administered as an intravenous infusion until the patient loses consciousness. Anesthesia is maintained at 1 mg/kg/hr of remimazolam. After confirming that the eyelash reflex disappears, rocuronium 0.8 mg/kg is administered, and SGA insertion is performed. During maintenance of general anesthesia, the concentration of remifentanil is continuously adjusted so that the ANI is above 50.

  • propofol groupDrug

    Propofol intravenous infusion is initiated by the application of a target concentration infusion (TCI) pump to cause the patient to lose consciousness. After confirming that the eyelash reflex disappears, rocuronium 0.8 mg/kg is administered, and SGA insertion is performed. During maintenance of general anesthesia, the concentration of remifentanil is continuously adjusted so that the ANI is above 50.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Intraoperative remifentanil consumption (mcg/kg/min)

    At the start of anesthesia induction, intravenous remifentanil infusion is started and the intraoperative remifentanil infusion rate is adjusted based on the ANI 50 during surgery. The total dose of remifentanil infused intraoperatively is recorded.

    Measured: Day 0, intraoperative

Secondary outcomes (2)
  1. Numeric rating scale pain score at rest

    Pain intensity at rest will be evaluated by an 11-point numeric rating scale (NRS: 0 = no pain, 10 = worst imaginable pain) 1, 6, 24 hours after the surgery.

    Measured: up to 24 hours after the surgery

  2. Postoperative opioid consumption

    Postoperative opioid consumption

    Measured: up to 24 hours after the surgery

Questions about this trial

What is this clinical trial studying?

A study testing remimazolam group and propofol group in people with Knee Osteoarthritis and Total Knee Arthroplasty, run by Gangnam Severance Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Intraoperative remifentanil consumption (mcg/kg/min) (time frame: Day 0, intraoperative). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jul 2023.
