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 Results may not be published yet.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.

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.

Summary

This study investigates whether high-flow nasal cannula (HFNC) oxygen therapy can reduce lung collapse (atelectasis) after laparoscopic surgery. About 90 adults undergoing elective laparoscopic procedures will receive either HFNC or standard oxygen after breathing tube removal. Doctors will use lung ultrasound to compare lung health between the two groups. The goal is to see if HFNC helps keep lungs open and lowers the risk of breathing problems after surgery.

What this could mean

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

Active substance
High-Flow Nasal Cannula (HFNC) oxygen therapy
What this could lead to
If effective, HFNC could become a standard way to prevent lung collapse after laparoscopic surgery, reducing breathing complications.
What could go wrong
This is a small observational study, not a large trial. Results may not apply to all patients, and HFNC might not significantly reduce atelectasis.
