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
