About this study

Official title: Correlative Analysis of Upper Airway Collapse in Sleep Endoscope and Submental Ultrasound

In this study, submental ultrasound during awake and simultaneous under Drug-induced sleep endoscopy is applied in the diagnostic workup of obstructive sleep apnea patients. The aim is to assess the tongue base thickness during awake and sleep with different head positions. By correlation with Drug-induced sleep endoscopy findings, more parameters could be used for evaluation and management of upper airway collapse in obstructive sleep apnea patients.

Read the detailed description

Obstructive sleep apnea (OSA) is a syndrome characterized by recurrent episodes of apnea and hypopnea during sleep that are caused by repetitive upper airway (UA) collapse and often result in decreased blood oxygen levels and arousal from sleep. Successful treatment lies in precise mapping the site of airway narrowing.

Drug-induced sleep endoscopy (DISE) is a well described modality to mimic the dynamic change of UA in OSA patients during natural sleep. Nevertheless, the tongue base thickness (TBT), one of the important anatomic factors in OSA, is hard to evaluate under this method. Recently, submental ultrasound (US), the noninvasive and convenient tool, has been widely applied to measure the TBT in awake OSA patients, so as to predict the severity and relationship with UA collapse. However, few evidence has addressed the relationship between UA collapse and the TBT in different head positions, awake and sleep period In this study, submental US during awake and drug induced sleep period is applied in the diagnostic workup of OSA patients. By correlation with DISE findings, more parameters could be used for evaluation and management of upper airway collapse in OSA patients.

  • submental ultrasonographyDiagnostic test

    Submental ultrasound, the noninvasive and convenient tool, has been widely applied to measure the tongue base thickness in patients with obstructive sleep apnea, so as to predict the severity and relationship with upper airway collapse.

What is being measured

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

  1. The value of drug induced sleep ultrasonography in patients with obstructive sleep apnea

    In this study, we proposed a novel method, drug induced sleep ultrasonography (DISU), which was applied to measure the tongue base thickness in OSA patients during drug induced sleep, so as to further understand the impact of dynamic change of tongue base thickness in OSA patients.

    Measured: May, 2017 to Aug, 2017

Questions about this trial

What is this clinical trial studying?

An observational study of Obstructive Sleep Apnea, run by Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation at 1 site in Taiwan.

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 1 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: status not confirmed, as of the sponsor's last update on 18 Sep 2017. 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 Taiwan. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Ming-Chin Lan, MD (+886920734552, lanmingchin@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The value of drug induced sleep ultrasonography in patients with obstructive sleep apnea (time frame: May, 2017 to Aug, 2017). 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 18 Sep 2017.
