About this study
Official title: Airway Management Effects of Flexible Reinforced Laryngeal Mask Airway Versus Endotracheal Tube for Childhood Adenotonsillectomy：a Randomized Controlled Trial
The goal of this clinical trial is to compare the airway management effects of flexible reinforced laryngeal mask and endotracheal tube in childhood adenotonsillectomy.
Participants will be randomly allocated to two groups: endotracheal tube group (ETT) and flexible reinforced laryngeal mask group (FLMA). For those in ETT group: they will be intubated after induction of anesthesia .For those in FLMA group: they will be put in flexible reinforced laryngeal mask after induction of anesthesia .
The investigators will compare FLMA with ETT to see if flexible reinforced laryngeal mask can be used safely and effectively in childhood adenotonsillectomy，and if there will be less severe adverse events in FLMA.
- Being tested
- Airway Management: Flexible Reinforced Laryngeal Mask Airway, Airway Management: Endotracheal Tube
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Airway Management: Flexible Reinforced Laryngeal Mask AirwayOther
In the FLMA group, a FLMA was applied according to the manufacturer's recommendations. After lubrication of the posterior surface with oxybuprocaine hydrochloride gel, the FLMA was inserted after propping the shoulders. Its cuff was fully deflated before insertion, and the pressure was adjusted to 40 cm H2O with a manometer after insertion.
Airway Management: Endotracheal TubeOther
In the ETT group, guided by a visual laryngoscope, a ETT was intubated after lubrication of the surface with oxybuprocaine hydrochloride gel: endotracheal tube size = (16+ age) /4. The cuff pressure of ETT was adjusted to 20 cm H2O with a handheld manometer after inflation.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Airway Management: Flexible Reinforced Laryngeal Mask Airway and Airway Management: Endotracheal Tube in people with Anesthesia Intubation Complication and Airway, run by Maternal and Child Health Hospital of Hubei Province at 1 site in China.
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 4 inclusion and 5 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 24 Apr 2024. 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 China. 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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Peak airway pressure (time frame: intraoperative period,10 minutes-1 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?
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 24 Apr 2024; AzTrials last refreshed its copy on 9 Nov 2026.
