About this study

Official title: Speaking Valve Combined With Airway Pressure Predicts Upper Airway Patency in Adult Tracheotomized Patients: a Prospective Cohort Study

This study was aimed to evaluate whether speaking valve combined with airway pressure could predict upper airway patency non-invasively in prolonged tracheostomized patients, identify candidates who need following endoscopy examination.

Read the detailed description

Tracheotomy is an effective means of treating critically ill patients, but its postoperative management faces many challenges, especially in the assessment and monitoring of upper airway patency. Although the indwelling tracheostomy tube plays an important role in maintaining airway patency and assisting breathing, it may also cause a series of complications, including airway stenosis, granulation tissue hyperplasia, airway collapse, and laryngeal dysfunction. The patency of the upper airway after tracheotomy is directly related to the patient's spontaneous breathing ability and quality of life. Although the existing bronchoscopy provides accurate diagnostic information, its invasiveness and high cost limit its application in extensive and high-frequency monitoring. Finding a non-invasive, easy-to-operate and accurate alternative method is of great clinical significance.The speaking valve is a one-way valve placed at the end of the tracheostomy tube that directs airflow to the upper airway when the cuff is deflated. Airway pressure measurement is a simple, non-invasive method that measures the pressure inside the tracheostomy tube to infer airway patency and resistance levels. Combining the two for a systematic assessment of upper airway patency in tracheostomy patients may provide a new, efficient, non-invasive monitoring tool for the clinic. By comparing the results of speaking valve combined with airway pressure measurement with the "gold standard" bronchoscopy results, its sensitivity and accuracy in assessing upper airway patency are verified, which is expected to not only provide a non-invasive, easier-to-use bedside assessment tool, but also improve the quality of patient care and their quality of life. Our hospital's respiratory rehabilitation center has the appropriate infrastructure and professional staffing to conduct research safely and in a standardized manner.

What participants receive

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

  • speaking valve combined with airway pressureDiagnostic test

    All patients were given speaking valves and airway pressure was measured to assess upper airway patency.

  • BronchoscopyDiagnostic test

    The same examiner performed bronchoscopy on all patients to assess upper airway patency.

What is being measured

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

  1. Upper airway patency

    Speaking valve combined with airway pressure protocol: After suction of oral and nasal secretion, the cuff was deflated. Then the speaking valve was placed. Supplement oxygen could be provided from nose. Connect a pressure measuring device for airway pressure. Then the tracheostomy tube was downsized according to patient's status (This decision was decided by a multidisciplinary team through consultation). Patients who could tolerate speaking valve and airway pressure<10cmH2O were assumed Upper airway patency group. Patients who cannot tolerate the speaking valve or whose airway pressure is ≥10cmH2O even after downsizing the tracheostomy are in the Upper airway obstruction group.

    Bronchoscopy protocol: Use bronchoscopy through nose to observe the upper airway through the glottis and around the cuff. Patients with bilateral vocal cord distance <3 mm or Cotton grade II or above were considered to have upper airway obstruction during bronchoscopy evaluation.

    Measured: The patients started using the speaking valve combined with airway pressure measurement on the day of enrollment. After that, bronchoscopy should be performed within 48 hours.

Questions about this trial

What is this clinical trial studying?

A study testing speaking valve combined with airway pressure and Bronchoscopy in people with Tracheotomy, run by Capital Medical University 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 7 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 2025. 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.

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?

Upper airway patency (time frame: The patients started using the speaking valve combined with airway pressure measurement on the day of enrollment. After that, bronchoscopy should be performed within 48 hours.). 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 2025.
