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 Results may not be published yet.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

Summary

This study compares two ways of adjusting the air cushion (cuff) on the breathing tube used during general anesthesia in children having laparoscopic appendectomy. One group uses the standard finger-palpation method, while the other uses a pressure sensor to keep the cuff within a safe range (15-18 mmHg). Researchers will check for sore throat, hoarseness, and cough at 2, 6, and 24 hours after surgery to see if active monitoring reduces these common side effects.

What this could mean

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

Active substance
Pressure transducer (device) for continuous cuff pressure monitoring
What this could lead to
If it works, this simple technique could become a standard way to prevent sore throat and hoarseness in children after surgery.
What could go wrong
This is a small, early-stage study with only 60 children, so results may not apply to all surgeries or ages. The benefit may be small or absent.
