Incidence rate of chronic pain after 1.5-2 years of thoracotomy between paravertebral block versus epidural block: a cohort study.

ABSTRACT: Paravertebral block and epidural block are frequently employed for post-thoracotomy pain relief. It is not clear which postoperative analgesia method is effective for the chronic pain after the postoperative long term progress. Our hypothesis was that paravertebral block would be more effective than epidural block for chronic pain 1.5-2 years after thoracotomy. A cohort study investigating postoperative pain was performed in lung cancer patients undergoing thoracotomy between the ages of 20-80 year-old, employed for another randomized controlled trial. In previously study, the patients were randomly allocated into either the epidural block or paravertebral block group (n = 36/group). Patients in each group received the respective block placement with continuous 0.2% ropivacaine infusion at
