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 Results may not be published yet.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 types of ultrasound-guided nerve blocks to see which provides better pain relief after colorectal surgery. Fifty adults scheduled for open colorectal surgery will receive either an erector spinae plane block or an oblique subcostal transversus abdominis plane block. Researchers will measure pain levels and how soon patients need extra pain medication.

What this could mean

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

Active substance
nerve block (local anesthetic injection)
What this could lead to
If one block works better, it could improve pain control after colorectal surgery and reduce the need for strong painkillers like morphine.
What could go wrong
This is a small, early-stage study with only 50 participants. Results may not apply to all patients, and nerve blocks carry risks like bleeding or infection.
