About this study

Official title: The Impact of the Timing of Rocuronium After Induction With Propofol on Temporal Summation of Pain in Gynecologic Laparoscopic Surgery-prospective and Controlled Study.

Temporal summation of pain, which is defined as the perception of increasingly greater pain evoked by repetitive painful stimuli, is highly variable between individuals. This study aimed to determine the impact of the timing of rocuronium after induction with propofol on temporal summation of pain in gynecologic laparoscopic surgery.

Being tested

What participants receive

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

  • The difference of the timing of rocuronium administration after propofol injectionOther

    The difference of the timing was rocuronium was administered immediately after propofol injection or when BIS score became below 60 after propofol administration.

What is being measured

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

  1. the grade of rocuronium induced withdrawal movement.

    withdrawal movements were graded by the investigator according to the following scale:

    1. - no pain (no response);
    2. - mild pain (movement at wrist only);
    3. - moderate pain (movement involving the arm only with elbow or shoulder);
    4. - severe pain (generalized response or movement in more than one extremity

    Measured: during anesthesia induction

Secondary outcomes (3)
  1. visual analog scale (VAS) for injection pain

    check VAS for pain after propofol administration. visual analog scale with 100 mm for pain after surgery. 0 = no pain, 100 = the worst pain

    Measured: during anesthesia induction

  2. VAS for pain

    check VAS with 100 mm for pain after surgery. 0 = no pain, 100 = the worst pain

    Measured: at 1 hour, 24 hours and 48 hours

  3. Patient controlled analgesia (PCA) Opioid consumption

    check the volume of PCA Opioid consumption (ml) (PCA) pump containing fentanyl (800 ug), ketorolac (150 mg), and ramosetron (0.6 mg) in a total volume of 150 mL of saline was set to deliver a basal infusion of 2 mL/h and bolus doses of 0.5 mL, with a 15-min lockout period for postoperative analgesia.

    Measured: at 24 and 48 hours

Questions about this trial

What is this clinical trial studying?

A study testing The difference of the timing of rocuronium administration after propofol injection in people with Gynecological Disorder, run by Wonkwang University 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 3 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 16 Sep 2020. 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?

the grade of rocuronium induced withdrawal movement. (time frame: during anesthesia induction). 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 NCT04547608, which also lists 4 linked publications.

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 16 Sep 2020.
