Comparison of the efficacy and safety of thoracic epidural and paravertebral block in postoperative analgesia after thoracic surgery: a meta-analysis of randomized trials

While TEA demonstrated slightly superior resting and movement pain control at the 24-h, these differences were no longer significant by 48 h. Most notably, PVB was associated with a significantly lower risk of hypotension, postoperative nausea and vomiting, and urinary retention. Overall, PVB is a safer and equally effective alternative to TEA for thoracic surgery.
