The goal of this study is to compare the efficacy in controlling postoperative pain of paravertebral block (PVB) with methylene blue visual confirmation and thoracic epidural anesthesia (TEA). This is a single center, parallel-group, prospective study. Patients will be randomly assigned in a 1:1 ratio to receive either PVB or TEA.
