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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is testing whether a special ultrasound technique called VExUS can help doctors manage fluids better during chest surgery. The goal is to see if it lowers the chance of lung and kidney problems after surgery. About 230 adults having video-assisted lung surgery will take part.

What this could mean

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

Active substance
Venous Excess Ultrasound (VExUS) protocol
What this could lead to
If successful, this could show that using VExUS ultrasound to guide fluid management reduces the risk of lung and kidney complications after thoracic surgery.
What could go wrong
This is a relatively small, early-stage study focused on measuring outcomes, not a treatment. The approach may not significantly improve patient outcomes or may be difficult to implement widely.

This is an AI summary of the original study and may miss details. Read our disclaimer.

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 230 people

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

Started

Nov 2024

Expected to finish

Nov 2029

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

18 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

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: * Adults \>18 years undergoing video assisted thoracic surgery/ lobectomy requiring one-lung ventilation. Exclusion Criteria: * Refusal to participate. * Pneumonectomy. * Young athletes (risk of physiologically large IVC \>2 cm). * Moderate-severe tricuspid regurgitation, moderate to severe pulmonary hypertension * Heart failure with reduced ejection fraction, EF\<35% * Portal hypertension, portal vein thrombosis, or liver cirrhosis. * Stage 4 or end-stage chronic kidney disease (eGFR \<30 mL/min/1.73 m² or dialysis). * Transfusion with more than 2 packed red blood cells unit perioperatively (intraoperatively, in the PACU, in the ward)
