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

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
