About this study

Official title: Diluted VAsopressin During Robot-assisted Laparoscopic myomEctomy for dimiNishing Blood Loss According To the Dilution Concentration of Normal salINE: a Randomized Controlled Pilot Study

The purpose of this study is to compare the effect of the concentration of vasopressin, which is used as a method for reducing blood loss in robot-assisted laparoscopic myomectomy.

Read the detailed description

This study is to compare the effect of the concentration of vasopressin, which is used as a method for reducing blood loss in robot-assisted laparoscopic myomectomy. We would like to evaluate the feasibility and validity of this study for future Phase III randomized clinical trials through this preliminary randomized assignment study.

Uterine fibroids are the most common tumors in women, and uterine myomectomy, which is performed as a treatment for them, is basically a high risk of bleeding and blood transfusion. A common method to reduce intraoperative bleeding is to inject diluted vasopressin into the subserosal areas of the fibroids. However, no proper level of vasopressin dilution has been determined so far, so we want to determine an effective dilution concentration of vasopressin that can minimize side effects through this clinical trial.

What participants receive

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

  • VasopressinDrug

    Also called Vasopressin 20U

    During robot-assisted laparoscopic myomectomy, vasopressin diluted to different concentrations will be injected before uterine serosal incision.

What is being measured

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

  1. Estimated blood loss (EBL) during operation

    The volume of blood loss will be estimated by using simple visual assessment technique referring to irrigation bottle

    Measured: during operation

Secondary outcomes (6)
  1. Hemoglobin

    Change of serum hemoglobin from baseline

    Measured: Post-op 1 day

  2. Hematocrit

    Change of serum hematocrit from baseline

    Measured: Post-op 1 day

  3. Operation running time

    Time from anesthesia start to delivery of patient to recovery room

    Measured: during operation

  4. Transfusion

    Whether patients are transfused during admission period Number of units transfused red blood cell

    Measured: Post-op 2 days

  5. The amount of fluid injected during operation

    The amount of fluid injected during operation

    Measured: during operation

  6. Hospitalization period

    Days from admission day to discharge day

    Measured: Within post-op 1 week

Questions about this trial

What is this clinical trial studying?

A study testing Vasopressin in people with Uterine Leiomyoma, run by Seoul National 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 6 inclusion and 7 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 26 Jun 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?

Estimated blood loss (EBL) during operation (time frame: during operation). 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 NCT04874246, which also lists 2 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 26 Jun 2023.
