What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a special breathing tube that can be seen with ultrasound, making it easier for doctors to confirm it's in the right place. Twenty children undergoing heart procedures will be intubated with the tube, and researchers will check if ultrasound can detect it. The goal is to see if this approach could replace X-rays for verifying tube placement.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Ultrasound-detectable endotracheal tube (a special breathing tube visible on ultrasound)
What this could lead to
If successful, this could lead to a safer, more reliable way to confirm breathing tube placement without X-rays.
What could go wrong
This is a very small, early feasibility study with only 20 participants. It only checks if the tube can be seen on ultrasound, not whether it improves patient outcomes.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 20 people

The number the study aims to enrol. It can still change while the study runs.

Started

Nov 2023

Expected to finish

Apr 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

6 to 42 months

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patient is undergoing scheduled or planned diagnostic or interventional cardiac catheterization with planned general anesthesia requiring endotracheal intubation. Exclusion Criteria: * Patient has a known airway abnormality, including tracheal stenosis, previous tracheal stenosis, or tracheobronchomalacia. * Patient has a tracheostomy. * Patient is ventilator-dependent. * Patient has an anticipated difficult intubation based upon airway exam and/or history of difficult intubation. * Patient is unlikely (in opinion of anesthesia team) or is unable to be intubated with 3.5 mm, 4.0 mm, or 4.5 mm Inner Diameter USD-ETT due to the size of the patient or their airway. * Patient is already intubated prior to the scheduled procedure. * It is anticipated that the patient will not be extubated after the catheterization procedure. * Concurrent enrollment in another clinical trial with an intervention during the cardiac catheterization procedure or 30 days afterwards. * Allergy to plastic/materials in USD-ETT
