Thoracic epidural versus paravertebral blockade for reducing chronic post-thoracotomy pain (TOPIC-2): open label, parallel group, superiority, multicentre, randomised controlled trial.
This open-label, multicentre, parallel-group superiority randomised trial compared perioperative paravertebral blockade with thoracic epidural in adults undergoing thoracotomy at 15 UK centres.
Why it matters
The trial addresses whether the choice of regional analgesia for thoracotomy affects persistent pain as well as immediate postoperative outcomes.
