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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial compares two ultrasound-guided nerve blocks—the erector spinae plane block and the external oblique intercostal plane block—to see which better supports breathing recovery after liver resection surgery. Adults aged 18-75 scheduled for elective liver surgery will be randomly assigned to receive one of the two blocks before the surgical incision. The study measures diaphragm movement, lung ultrasound scores, oxygen needs, and lung complications, along with pain intensity, to determine which block offers better respiratory recovery and pain control.

What this could mean

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

Active substance
Ultrasound-guided nerve blocks (erector spinae plane block or external oblique intercostal plane block) with bupivacaine
What this could lead to
If one block proves better, it could become the standard for easing pain and speeding breathing recovery after liver surgery.
What could go wrong
This is a single-center trial with 116 patients, so results may not apply broadly. Nerve blocks carry small risks like bleeding or infection, and the benefit over standard care is not guaranteed.

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 116 people

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

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 aged 18-75 years * Adult with American Society of Anesthesiologists (ASA) physical status I-III * Scheduled for elective hepatic surgery via upper abdominal incisions will be eligible. * All participants will be required to understand the Numeric Rating Scale (NRS) and provide informed consent.
