Effect of bilateral ultrasound-guided erector spinae blocks on postoperative pain and opioid use after lumbar spine surgery: A prospective randomized controlled trial

Background: The control of postoperative pain following major lumbar spine surgeries remains a challenge for anesthesiologists, and many new strategies methods have been developed control. This study’s main objective was to evaluate the efficacy bilateral ultrasound-guided erector spinae plane block (US-ESPB) as method perioperative management in patients undergoing surgeries.Methods: double-blinded prospective randomised controlled study conducted on 140 aged between 18 65 years; all were scheduled elective surgeries. Patients randomly allocated into one two groups: ESPB group (n = 70) or 70). All received US-ESPB after induction general anaesthesia, group; 20 mL levobupivacaine 0.25% used, while normal saline given instead. primary endpoint total amount morphine consumed during intraoperative first 24 hours. Secondary endpoints included, time request rescue analgesia well incidence adverse effects.Results: hours found be significantly lower compared (P < 0.001). Moreover, analgesic longer receiving No statistically significant differences observed groups regarding complications.Conclusion: Bilateral is useful intervention providing adequate
