About this study

The "Analgesia Nociception Index" (ANI; MetroDoloris Medical Systems, Lille, France), derived from an electrocardiogram (ECG) trace, has been proposed as a noninvasive guide to analgesia. The ANI monitor calculates HR variation with respiration, a response mediated primarily by changes in the parasympathetic nervous system (PNS) stimulation to the sinoatrial node of the heart. The aim of this study is to determine the relation between ANI monitor values and serum catecholamine levels. We will compare the serum catecholamine (norepinephrine, epinephrine) levels of conventional nociception control group and ANI-monitor guided nociception control group at the end of surgery.

Being tested
conventional nociception control, ANI monitor guided nociception control

What participants receive

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

  • conventional nociception controlDevice

    While Intraoperative opioid will be administered by conventional clinical practice in control arm.

  • ANI monitor guided nociception controlDevice

    The intraoperative opioid will be administered by maintaining the 4-minute moving average of ANI ≥50 in ANI-monitor guided nociception control arm.

What is being measured

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

  1. Serum catecholamine (norepinephrine, epinephrine) level at the end of surgery

    Blood samples for serum catecholamine (norepinephrine, epinephrine) will be drawn at the end of surgery and 1 hour after the end of surgery..

    Measured: at the end of surgery (skin closure)

Secondary outcomes (3)
  1. plasma inflammatory markers (IL-6, IL-10, HMGB1)

    Blood samples for plasma inflammatory markers (IL-6, IL-10, HMGB1) will be drawn at the end of surgery (skin closure) and 1 hour after the end of surgery.

    Measured: at the end of surgery (skin closure) and 1 hour after the end of surgery

  2. hormone level (cortisol, adrenocorticotropic hormone)

    blood samples for hormone levels (cortisol, adrenocorticotropic hormone) will be drawn at the end of surgery (skin closure) and 1 hour after the end of surgery.

    Measured: at the end of surgery (skin closure) and 1 hour after the end of surgery

  3. serum catecholamine (norepinephrine, epinephrine) level

    Blood samples for serum catecholamine (norepinephrine, epinephrine) will be drawn 1hour after surgery.

    Measured: 1 hour after the surgery

Questions about this trial

What is this clinical trial studying?

A study of Patients Undergoing Total Laparoscopic Hysterectomy, run by Yonsei University 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 1 inclusion and 8 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 29 Dec 2021. 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?

Serum catecholamine (norepinephrine, epinephrine) level at the end of surgery (time frame: at the end of surgery (skin closure)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04343638, which also lists 1 linked publication.

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 29 Dec 2021.
