About this study
Official title: Benefit of Intraoperative Lung Ultrasound in Pediatric Patients Undergoing Cardiac Surgery
Investigators hypothesized that perioperative lung ultrasound would be beneficial in pediatric patients undergoing cardiac surgery compared to those who did not receive lung ultrasound.
- Being tested
- Lung ultrasound
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Lung ultrasoundDevice
Lung ultrasound with appropriate interventions depending on the ultrasound finding
| Study group | Role | What they receive |
|---|---|---|
| Control | Placebo comparator | No intervention during the perioperative period. Perform lung ultrasound twice only for the diagnostic purpose at the end of surgery and 6 to 12 hours after surgery in the intensive care unit. Receives: Device: Lung ultrasound |
| Ultrasound | Active comparator | Perform lung ultrasound three times during the perioperative period; after the induction of general anesthesia, at the end of surgery, and 6 to 12 hours after surgery in the intensive care unit. According to the lung ultrasound finding, conduct appropriate interventions such as, alveolar recruitment maneuver for atelectasis, or chest tube insertion for pneumothorax. Receives: Device: Lung ultrasound |
What is being measured
The primary outcome is the main question the study is designed to answer.
Intraoperative incidence of pulse oximetry (SpO2) ≤ 95% (or 10% below the baseline value)
Measured: from the induction of general anesthesia until the end of the surgery, up to 24 hours
Postoperative incidence of SpO2 ≤ 95% (or 10% below the baseline value)
Measured: within the first day after surgery
Postoperative incidence of respiratory complications
Measured: within the first day after surgery
Secondary outcomes (4)
Intraoperative partial pressure of oxygen in arterial blood (PaO2) from arterial blood gas analysis
Measured: from the induction of general anesthesia until the end of the surgery, up to 24 hours
Postoperative partial pressure of oxygen in arterial blood (PaO2) from arterial blood gas analysis
Measured: within the first day after surgery
Initial SpO2 on arriving at pediatric intensive care unit
Measured: from the end of the surgery until postoperative 1 hour
Days needed to wean from mechanical ventilation
Measured: up to 1 month

Questions about this trial
What is this clinical trial studying?
A study testing Lung ultrasound in people with Ultrasonography and Pediatrics, 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 1 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 26 Dec 2016. 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. Some participants in this study may receive a placebo. 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?
Intraoperative incidence of pulse oximetry (SpO2) ≤ 95% (or 10% below the baseline value) (time frame: from the induction of general anesthesia until the end of the surgery, up to 24 hours). The study lists 3 primary outcomes in all. 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 NCT02535013, which also lists 5 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 Dec 2016; AzTrials last refreshed its copy on 7 Nov 2026.
