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
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Completed This study
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 Results may not be published yet.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.

Summary

This study compares two methods of giving a nerve block to control pain after lung surgery (thoracotomy). One method uses ultrasound to guide the needle, the other uses a camera inside the chest during minimally invasive surgery. The goal is to see which approach reduces the need for morphine and improves recovery. 180 adults having lung surgery will take part.

What this could mean

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

Active substance
Thoracic paravertebral block (pain relief procedure)
What this could lead to
If successful, this could show that one method of pain block is better or easier, leading to less morphine use and faster recovery after lung surgery.
What could go wrong
This is a small, single-center study comparing two established techniques, so any difference may not apply to all hospitals or patients. The main risk is that neither method proves clearly superior.
