Article Notes
Article pearls, summaries and comments.
Although this Cochrane review supports the belief that epidural and paravertebral blocks may reduce persistent-surgical pain after thoracotomy or breast cancer surgery respectively, the authors highlight the low total number of subjects (only 339 patients) in the five trials analysed. This is enough evidence to consider the PSP-benefits of regional anesthesia, but far from enough to be conclusive or change practice.
