About this study
Official title: Comparation of Efficacy and Safety of Proseal Laryngeal Mask Airway With Flexible Laryngeal Airway Mask in Otitis Media Surgery
Objective To investigate the comparative effect of proseal laryngeal mask airway and flexible laryngeal airway mask during otitis media surgery. Methods 200 patients of ASA I or II classification, 18-65 years old, BMI<30 kg/m2 undergoing otitis media surgery are randomly divided into two groups (Group P with proseal laryngeal mask airway and Group F with flexible laryngeal airway mask, respectively). After induction, selecting a appropriate size of LMA to patient,s weight, using the standard index finger-guided technique inserting the LMA, and then the patients were ventilated mechanically. The success rate of inserting laryngeal mask, the intubation time, surgery time and wake time were also recorded. Tidal volume and leakage pressure in patients with supine and lateral positioning were assessed respectively. The scale of fiberoptic bronchoscopy was also recorded to show airway exposure. Related complications such as sore throat, hoarseness, cough, laryngospasm, bloating, nausea and vomiting, soft tissue injury, blood residue after pulling out the LMA were analyzed.Postoperative voice and laryngopharyngeal symptom are also recorded.

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 19 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.
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?
Results are not available in the source record.
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?
successful insert rate (time frame: 0 minute after insertion). The study lists 5 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 19 Aug 2021; AzTrials last refreshed its copy on 8 Nov 2026.
