Effect of Intraoperative Paravertebral Block on Postoperative Pain and Recovery in Patients Undergoing Mechanical Correction for Scoliosis

Overview

Pain management after scoliosis surgery is challenging for the anesthesiologists. This surgery causes severe postoperative pain and patients undergoing these operations are children or adolescents who are increased pain sensation compared with adults. Therefore, we aim to evaluate whether intraoperative paravertebral block (PVB) decreases postoperative pain in these patients. Thirty-two patients scheduled for mechanical correction due to scoliosis will be divided into PVB (n=16) and control (n=16) groups. Randomly selected patients of the PVB group are performed PVB with 0.2% ropivacaine on both sides. In contrast, PVB are not performed in the control group.
