Abstract
Background and aims Optimal postoperative care and analgesia are the key factors in the management of cases of lumbosacral spine surgery. The erector spinae plane (ESP) block is a recently evolving entity and has a dynamic role in postoperative pain management. However, its role in the management of pain in lumber spinal surgeries is still not clear, and the literature remains anecdotal. Therefore, we planned to study the efficacy of ultrasound-guided preoperative ESP block at the T12 level using levobupivacaine for perioperative analgesia in lumbosacral spine surgeries. Methods A total of 60 patients scheduled for elective or emergency lumbosacral spine surgery were divided into two groups - the GA group received standard general anesthesia (GA) and the GA+ESP group received standard general anesthesia along with ultra-sound guided ESP block at the T12 level with a bilateral injection of 20 ml 0.25% levobupivacaine. Perioperative analgesia was assessed by total intra-operative fentanyl dose and frequency, intra-operative hemodynamic parameters, post-operative numeric rating scale (NRS) scores, time of first systemic rescue analgesia, tramadol usage, mobilization day, and hospital stay duration. Results Intraoperative fentanyl sparing was observed in 83% of the GA+ESP group compared to 33% in the GA group. Postoperative tramadol sparing was observed in 80% of the GA+ESP group compared to 26.7% of the GA group. Twenty-four-hour postoperative NRS scores >3/10 were observed in 20% of the GA+ ESP group compared to 73.3% of the GA group. Conclusion In this study, superior perioperative analgesia, opioid-sparing effect, and decreased requirement of postoperative rescue analgesia were observed with ESP block.
