About this study

The main purpose of this study is to investigate voice production, speech intelligibility and routine physiologic parameters associated with the Blom low profile voice inner cannula and the Passy-Muir one-way tracheotomy tube speaking valves.

Additionally, the purpose of this study is to investigate the effects (if any) associated with the Blom low profile voice inner cannula and the Passy-Muir one-way tracheotomy tube speaking valves on swallowing behavior and biomechanical movement of the hyolaryngeal complex during routine diagnostic modified barium swallowing evaluations.

Read the detailed description

The goal of a one-way tracheotomy tube speaking valve is to allow cognitively intact individuals who require a tracheotomy tube communicate with their own voice. All non-verbal communication strategies have shortcomings. Lip reading is unreliable, communication boards are simplistic, writing very laborious, and computerized augmentative communication systems too costly. This inability to communicate effectively prevents optimal patient participation in their plan-of-care. Verbal communication, therefore, plays an integral role in psychological functioning, social interactions, and overall medical care.

The primary criteria for determining success or failure of any one-way tracheotomy tube speaking valve is how well it allows for adequate voice intensity greater than ambient room noise to achieve both audible voice production and intelligible speech. The first purpose of this study is to investigate voice production and speech intelligibility abilities associated with the Blom low profile voice inner cannula and the Passy-Muir one-way tracheotomy tube speaking valves. It is hypothesized that there will be no significant differences between the two speaking valves regarding physiologic parameters, voice production, or speech intelligibility capabilities.

There are conflicting reports in the literature regarding the relationship between a tracheotomy tube and swallowing success. Some authors report an improvement in swallowing success when the tracheotomy tube is occluded while others report no change in aspiration status based on occlusion status of the tracheotomy tube. Recently, it has been reported that there was no causal relationship between the tracheotomy tube and aspiration status. There is a paucity of research, to date, reporting on movement of the hyolaryngeal complex based upon occlusion status of a tracheotomy tube or presence of a tracheotomy tube. The second purpose of this study is to investigate how the Blom low profile voice inner cannula and the Passy-Muir one-way tracheotomy tube speaking valves impact on swallowing behavior and movement of the hyolaryngeal complex during routine diagnostic modified barium swallow evaluations.

Study groupRoleWhat they receive
Speaking ValvesExperimentalAll participants will either have a Blom tracheotomy tube in place or have their current tracheotomy tube changed to a Blom tracheotomy tube to allow for use of both the Blom low profile voice inner cannula and the Passy-Muir one-way speaking valves. The Blom low profile voice inner cannula and Passy-Muir speaking valves will be provided to participants in a random order. All valves will be placed by the PI. Duration of data collection trials will range from 10 to 30 minutes.
Receives: Procedure: Blom Low Profile Voice Cannula/Passty-Muir Speaking Valves

What is being measured

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

  1. Maximum Duration of Voicing (seconds)

    Maximum duration of voicing (seconds) will be obtained, after instructing the patient to say the vowel /a/ as long as possible timed with a stopwatch.

    Measured: 30 minutes

  2. Maximum Voice Intensity (dBA scale)

    Maximum voice intensity (on the dBA scale) will be obtained, after instructing the patient to say the vowel /a/ as loud as possible, using a digital sound level meter placed 15 cm from the patient's lips.

    Measured: 30 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Blom Low Profile Voice Cannula/Passty-Muir Speaking Valves in people with Mechanical Complication of Tracheostomy, run by Yale University at 1 site in United States.

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: finished, as of the sponsor's last update on 13 Jun 2014. 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 United States. 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?

Maximum Duration of Voicing (seconds) (time frame: 30 minutes). The study lists 2 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 13 Jun 2014.
