  "abstract": "Background and Aims Lumbar spine surgery is commonly associated with severe postoperative pain, which can impair recovery, extend mobilization, and cause chronic pain. Erector spinae plane block (ESPB) is a regional analgesia technique as a potent option in numerous surgical procedures. Our study aims to evaluate the effects of preoperatively administered ESPB on postoperative pain, opioid consumption, and cognitive functions in patients undergoing lumbar surgery.Methods This prospective, randomized, single-center study included 56 patients aged 18–65 years with ASA physical status I–II, who were undergoing elective lumbar spine surgery. Patients were randomly assigned to either the ESPB group or the sham block group. Before the surgery, both groups underwent ultrasound-guided ESPB, with one group receiving 0.3 ml/kg of 0.25% bupivacaine injection on both sides, while the other group received only hydrodissection. Pain was assessed on the Visual Analog Scale (VAS), cognition on the NuDESC scale, and additional outcomes such as opioid consumption, nausea, vomiting, anxiety, stress, and satisfaction with the patient. The data were analyzed using SPSS 11.5 software.Results A total of 56 patients were included in the study. Differences in variables between the ESPB and sham block groups were examined, but no significant differences were found between the two groups for any variables (p>0.05). In the group that received ESPB, postoperative pain scores at rest and during movement (VAS scores) and opioid consumption were found to be significantly lower compared to the sham block group (p<0.05). The overall well-being was significantly higher in the ESPB group (p=0.048).Abstract EP148 Figure 1Erector spinae plane block USG visionConclusions The application of ESPB after lumbar surgery is effective in controlling postoperative pain and contributes to the prevention of side effects by reducing opioid consumption. While it does not have a significant impact on postoperative cognitive functions, the use of ESPB as part of multimodal analgesia is recommended.",
