Summary

This trial tests two ultrasound-guided nerve blocks for pain relief after thoracotomy, a surgery that opens the chest. One block targets the paravertebral space, while the other targets a point between the transverse process and the pleura. Researchers will compare how much morphine patients need in the first 24 hours after surgery, along with pain scores and complications. The study includes adults aged 18 to 65 scheduled for elective thoracotomy.

What this could mean

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

Active substance
levobupivacaine
What this could lead to
If one block proves better, it could offer safer and more effective pain control after chest surgery, reducing the need for morphine.
What could go wrong
This is a small, early-stage trial, so results may not apply to all patients. Both blocks carry risks like accidental lung puncture or local anesthetic side effects.
