Efficacy of erector spina plane blocks and paravertebral blocks in kyphoplasty surgery

Aims: Kyphoplasty (KP) surgeries are commonly performed under local, general and regional anesthesia. The purpose of our study was to compare the perioperative and postoperative effects of ultrasound (USG) guided erector spinae plane blocks (ESPB) and paravertebral blocks (PVB) in patients with KP. Methods: Forty patients who underwent kyphoplasty were evaluated retrospective as Group 1 (ESPB, n=20) and Group 2 (PVB,n=20). Perioperative additional opioid, hemodynamic parameters, complications, postoperative analgesia requirement, pain with visual analog scale (VAS) at specified times, amount of analgesic used within 24 hours, first mobilization and discharge time, and complications were compared. Results: There was no difference between the study groups regarding demographic data, ASA, preoperative analgesic use, mean arterial pressure (MAP), heart rate (HR), SpO2, additional opioid requirement, perioperative complication rates, VAS and surgical level. A significant difference was observed between Group 1 and Group 2 regarding the VAS score and paracetamol dose at 6 hours postoperatively (p:0.023 and p:0.006, respectively). There was no statistical difference between the groups first mobilization and discharge time, postoperative complications, postoperative intensive care needs (PICU), and tramadol dose rates used (p>0.05). Conclusion: The USG-guided ESPB and PVB did not appear superior to one another in kyphoplasty procedures regarding 12 and 24-hour VAS scores, first mobilization and discharge time, postoperative complications, PICU needs and tramadol dose. The analgesic effect of ESPB in KP surgery was superior to that of PVB, 6hours postoperatively. Therefore, it is possible to consider them a safe and alternative method of anesthesia and analgesia.
