Efficacy of Dexmedetomidine Plus Ropivacaine 0.375% Versus Dexamethasone Plus Ropivacaine 0.375% Administered by Ultrasound-Guided Bilateral Spinal Erector Block on Post-Surgical Patients of Lumbar Spine Surgery

Introduction: The ultrasound-guided erector spinae block is an analgesic option that has shown a positive response in postoperative pain control in spinal surgery. Objective: To evaluate the efficacy of dexmedetomidine plus 0.375% ropivacaine compared with dexamethasone plus 0.375% ropivacaine administered in the ultrasound-guided bilateral erector spinae plane in the management of postoperative pain in patients undergoing lumbar spine surgery at Hospital Civil de Guadalajara. Material and Methods: Fourteen patients scheduled for lumbar spine surgery were included, divided into two groups. Group A received dexmedetomidine plus ropivacaine bilaterally in the plane of the spinal erector guided by ultrasound, while group B received ropivacaine plus Bilateral dexamethasone using the same technique. Results: Post-surgical pain in group A and group B presented an average baseline pain of 3.88 ± 0.84 and 5.17 ± 1.17 on VAS, respectively. At 8 hours, an average value of 3.13 ± 1.64 and 2 ± 1.55 on VAS, at 24 hours. hours was 2.13 ± 0.84 and 2.33 ± 1.03 VAS and at 48 hours it was 1.88 ± 0.641 and 2.33 ± 1.37 VAS. Conclusions: The administration of dexamethasone generates a more effective analgesia at 8 postoperative hours compared to dexmedetomidine in our group. The spinal erector plane block is a good alternative for postsurgical pain, demonstrating efficacy and safety in patients scheduled for lumbar spine surgery.
