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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares a less invasive device that uses sound waves to measure blood flow from the heart (esophageal Doppler) with a standard, more invasive method (transpulmonary thermodilution) in children who are sedated and on breathing machines. The goal is to see if the gentler approach gives equally reliable readings of cardiac output and stroke volume. If it does, it could offer a safer way to monitor heart function in critically ill young patients.

What this could mean

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

Active substance
CardioQ (esophageal Doppler cardiac output monitor) compared to PiCCO (transpulmonary thermodilution cardiac output monitor)
What this could lead to
If successful, this could validate a less invasive way to measure heart function in critically ill children, potentially reducing risks associated with more invasive monitoring.
What could go wrong
This is a small validation study with only 11 participants, so results may not apply broadly. The device may not match the accuracy of the standard method.

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.

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.

Anyone

Healthy volunteers

Not accepted

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

Show the full entry requirements

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

Inclusion Criteria: * Patients aged 0 to 16 years with an indication for invasive CO monitoring (TPTD). Indication for invasive CO monitoring always implies intubation and sedation. * Signed informed consent Exclusion Criteria: * Congenital or acquired cardiovascular diseases (intracardiac/extracardiac intrathoracic shunt * Cardiac valve diseases * Aortic arch anomalies * Tissue necrosis of oesophagus * Carcinoma of pharynx, larynx of oesophagus * Severe bleeding diatheses * Age \> 16 years * Weight \< 3.5 kg or \> 50 kg.
