What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 whether a quick, bedside ultrasound of the internal jugular vein in the neck can help tell how severe bronchiolitis is in infants aged 1 to 23 months. Researchers will measure how much the vein's diameter changes with breathing and compare that to standard clinical severity scores, oxygen levels, and need for intensive care. No treatment is given—the ultrasound is added to usual care to see if it can serve as a reliable marker of disease severity.

What this could mean

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

Active substance
Point-of-care ultrasonography (POCUS) measuring internal jugular vein diameter variation
What this could lead to
If it works, this could give doctors a quick, non-invasive way to gauge bronchiolitis severity in infants, helping guide treatment decisions.
What could go wrong
This is an observational study, so it can only show a link, not prove cause. The ultrasound technique may not reliably predict severity in all infants, and results may not apply beyond this specific setting.

Who can take part

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

Who is studied

Infants aged 1 to 23 months presenting to the Pediatric Emergency Department with a clinical diagnosis of acute bronchiolitis according to the American Academy of Pediatrics (AAP) clinical criteria will be prospectively enrolled. Eligible participants will be evaluated within the first 6 hours of emergency department presentation after written informed consent is obtained from a parent or legal guardian. Participants will undergo standardized clinical severity assessment and point-of-care ultrasonography of the internal jugular vein, lungs, and diaphragm in addition to routine clinical care. No study-specific therapeutic intervention will be assigned.

Ages

Inclusion Criteria: * Infants aged 1-23 months * Clinical diagnosis of acute bronchiolitis per AAP (2014) criteria (first wheezing episode following an upper respiratory infection prodrome, with tachypnea, retractions, and/or crackles) * Written informed consent obtained from parent/legal guardian * Evaluable within the first 6 hours of emergency department presentation Exclusion Criteria: * Underlying congenital heart disease * Chronic lung disease (bronchopulmonary dysplasia, cystic fibrosis) * Prior history of recurrent wheezing/suspected asthma * Anatomical abnormality of the neck or prior history of central venous catheterization or jugular vein thrombosis * Hemodynamic instability/shock * Immediate need for intubation/mechanical ventilation precluding ultrasound assessment * Parent/legal guardian declines consent
