Objective To investigate the clinical effects of local analgesia in treatment of thoracolumbar fractures with percutaneous pedicle screw fixation. Methods Using self-control prospective method, 35 patients with thoracolumbar fractures who underwent percutaneous pedicle screw fixation in our department from Jan 2014 to Mar 2016 were enrolled in this study. For every patient, the right incision and left incision were randomly divided into group A (local analgesia with combination of ropivacaine and epinephrine), and group B (control group). The VAS of unilateral back pain after surgery (3, 6, 12, 24, 48 h, 1 year), preoperative and 1 year postoperative ODI, postoperative complications and incisions were recorded. Results VAS score in local analgesia group were lower than those in control group at 3, 6, 12, 24 h (P<0.05); there were no significant differences in 48 h and 1 year VAS score between the 2 groups (P>0.05). 1 year postoperative ODI were lower than preoperative ODI (P<0.05). No serious postoperative complication was found in these patients. Conclusion Local analgesia with combination of ropivacaine and epinephrine in posterior spinal surgery can effectively reduce early pain after operation, which is a simple, safe and effective early analgesia method. |
