Erector Spinae Block -Dexmedetomidine
Postoperative pain is common after spinal surgeries, including lumbar disc surgery. Surgical anesthesia and perioperative analgesic regimen are aimed at complete intraoperative amnesia, deep analgesia, effective control of autonomic responses and rapid discharge from the hospital.

Although there are many studies on the use of these techniques for postoperative analgesia, the number of data comparing these techniques that can be used in meta-analyses is low. In our study, investigators aimed to compare the effects of remifentanil and dexmedetomidine accompanied by ESP block, which are different multimodal analgesia methods, on pain.
