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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 international trial investigates whether the way a patient's airway is managed during general anesthesia affects the risk of lung complications after surgery. Researchers randomly assign about 6,800 adults having elective non-cardiac surgery to different combinations of breathing tube type and muscle relaxation depth. The goal is to see which approach, if any, leads to fewer postoperative pulmonary complications during the hospital stay.

What this could mean

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

Active substance
airway management strategy and neuromuscular blockade during general anesthesia
What this could lead to
If certain airway or muscle-relaxation approaches lower lung complications, anesthesiologists could adjust routine practice for millions of surgeries worldwide.
What could go wrong
The trial may find no meaningful difference between approaches, or benefits seen in controlled settings may not hold across diverse hospitals and patients.

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 6,800 people

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

Expected to start

Oct 2026

An estimate. Start dates often move.

Expected to finish

Sep 2030

An estimate. End dates often move.

Lead sponsor

Other sponsor

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: Adult patients (≥ 18 years) with an ASA physical status ≤ 3 scheduled for elective non-cardiac surgery under general anaesthesia whose airway can be secured via tracheal tube or SGA. Exclusion Criteria: Contraindications for using supraglottic devices, tracheal tube, or neuromuscular blocking agents (and reversal drugs); surgery in prone positioning; surgical procedures scheduled outside the operating room; ambulatory surgery; pregnancy; patients planned for consecutive anaesthetic/surgical procedures in the following 14 days or within the past 14 days.
