Thoracic Paravertebral Block for Postoperative Analgesia After Video-assisted Thoracic Surgery. (PARAVI)

December 13, 2025 updated by: Hospices Civils de Lyon

Thoracic Paravertebral Block: a Comparative Study of Ropivacaine With Ropivacaine and Sufentanil for Treating Pain After Video-assisted Thoracic Surgery.

The use of paravertebral catheters is a recommended technique to achieve postoperative analgesia after thoracic surgery. To date there is no consensus on which drug regime (local anesthetics with or without opioid) is best. The aim of this prospective clinical trial is to determine wether the use of ropivacaine and sufentanil injected through a thoracic paravertebral catheter results in decreased acute postoperative pain compared with plain ropivacaine in patients after thoracoscopic lung surgery.
