About this study

Official title: The Effect of Ultrasound-guided Alveolar Recruitment on Postoperative Atelectasis in Patients Receiving Laparoscopic Gynecological Surgery

The study aims to compare the degree of atelectasis between ultrasound-guided alveolar recruitment group and conventional alveolar recruitment group in patients receiving laparoscopic gynecologic surgery

Being tested
lung ultrasound-guided alveolar recruitment, conventional alveolar recruitment
Medical subject headings
Pulmonary Atelectasis

What participants receive

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

  • lung ultrasound-guided alveolar recruitmentProcedure or surgery

    Alveolar recruitment maneuver will be performed under lung ultrasound-guidance. Positive pressure will be not exceed 40cmH2O and duration of positive pressure inflation will not exceed 10 seconds.

  • conventional alveolar recruitmentProcedure or surgery

    Alveolar recruitment will be provided with positive pressure of 30cmH2O for 10 seconds

What is being measured

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

  1. modified lung ultrasound score at the end of surgery

    Both lung ultrasound scores can be calculated by adding up the 12 individual pulmonary quadrant scores yielding a score between 0 (no aeration loss) and 36 (complete aeration loss).

    Measured: At the end of surgery

Secondary outcomes (8)
  1. modified lung ultrasound score at post-anesthesia care unit (PACU)

    Both lung ultrasound scores can be calculated by adding up the 12 individual pulmonary quadrant scores yielding a score between 0 (no aeration loss) and 36 (complete aeration loss).

    Measured: intraoperative

  2. incidence of atelectasis diagnosed by ultrasonography

    the presence of atelectasis by ultrasonography

    Measured: intraoperative

  3. arterial blood gas analyses

    PaO2, PaCO2, SaO2, O2 index (PaO2/FiO2)

    Measured: intraoperative

  4. incidence of postoperative complications

    fever, pneumonia, atelectasis diagnosed by chest X-ray

    Measured: during the postoperative period until discharge from hospital, an average of 3 days

  5. intraoperative mean arterial pressure

    mean arterial pressure in mmHg

    Measured: intraoperative

  6. intraoperative SpO2

    SpO2 in %

    Measured: intraoperative

  7. intraoperative peak airway pressure

    peak airway pressure in cmH2O

    Measured: intraoperative

  8. Incidence of postoperative shoulder pain at POD #1

    patients will be asked whether they have shoulder pain or not, using NRS (0 to 10) scale

    Measured: assessed at postoperative day 1

Questions about this trial

What is this clinical trial studying?

A study testing lung ultrasound-guided alveolar recruitment and conventional alveolar recruitment in people with Pulmonary Atelectasis, run by Seoul National University Hospital at 2 sites 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 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 18 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

modified lung ultrasound score at the end of surgery (time frame: At the end of surgery). 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 NCT03607240, which also lists 3 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 18 Oct 2019.
