What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
recruitment maneuverProcedure or surgery
Recruitment maneuver is provided with positive pressure of 30 cmH2O for 10 seconds.
ultrasonography-guided recruitment maneuverProcedure or surgery
Recruitment maneuver is guided by ultrasonography.
| Study group | Role | What they receive |
|---|---|---|
| Recruitment maneuver group | Active comparator | After anesthetic induction, recruitment maneuver is provided with positive pressure of 30 cmH2O for 10 seconds. Receives: Procedure: recruitment maneuver |
| Lung ultrasonography group | Experimental | After anesthetic induction, recruitment maneuver is performed, being guided by ultrasonography. Receives: Procedure: ultrasonography-guided recruitment maneuver |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of postoperative atelectasis
Postoperative atelectasis is measured using lung ultrasonography
Measured: within 1 hour after the end of surgery

Questions about this trial
What is this clinical trial studying?
A study testing recruitment maneuver and ultrasonography-guided recruitment maneuver in people with Atelectasis, 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 3 inclusion and 4 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 15 May 2019. 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?
Incidence of postoperative atelectasis (time frame: within 1 hour after 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 NCT03453762, 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 15 May 2019; AzTrials last refreshed its copy on 7 Nov 2026.
