A Block Method for Pain After Back Surgery

Overview

The purpose of this clinical trial is to evaluate whether bilateral lumbar erector spinae plane (ESP) block can reduce postoperative pain in adult patients undergoing lumbar spine surgery. The study also assesses the safety of this method and its effects on the recovery process. The main questions it aims to answer are: Do patients who receive the ESP block experience less postoperative pain? Do these patients require fewer opioid (morphine-derived) analgesics? Does the first analgesic requirement occur later? Do patients mobilize earlier (stand/walk sooner)? Does the ESP block affect hemodynamic stability during and after surgery? Researchers will compare the ESP block group with the standard analgesia group to determine whether these effects occur. Participants: Patients in this study will be asked to: Be randomly assigned to one of two groups before lumbar spine surgery Receive either a bilateral ESP block or standard analgesic therapy Undergo postoperative follow-up including: measurement of pain scores, recording of analgesic consumption, assessment of time to first analgesic requirement, monitoring of mobilization time, valuation of possible side effects

This randomized controlled study was designed to evaluate the effect of bilateral lumbar erector spinae plane (ESP) block on postoperative analgesia in patients undergoing lumbar spine surgery. A total of 102 patients scheduled for lumbar spine surgery were enrolled in the study and randomly assigned into two groups. One group received a bilateral ESP block at the L2-L4 levels using 20 mL of 0.25% bupivacaine on each side, while the control group received standard postoperative analgesia. Postoperative pain assessment, opioid consumption, time to first analgesic request, mobilization time, intraoperative hemodynamic parameters, and the occurrence of adverse events were prospectively recorded according to a predefined follow-up protocol. The study was conducted using a prospective, randomized design to assess the efficacy and safety of bilateral lumbar ESP block for postoperative pain management in lumbar spine surgery.
