Brief Summary

Spinal surgery patients generally have chronic pain in the preoperative period and are exposed to widespread and severe acute pain postoperatively. In spinal surgery patients, providing postoperative analgesia is important not only for the patient's comfort but also for preventing the negative effects of pain on the systems, allowing early mobilization, reducing hospital stay and especially reducing chronic pain syndrome. Although ESP block is routinely used in spinal analgesia, the answer to the question of whether investigators should perform the block after putting the patient to sleep or before waking the patient after completing the surgery is not clear. Preference varies among anesthesiologists.YOU investigators propose a randomized double-blind study comparing patients who underwent ESP block before surgery (Group 1) with patients who underwent ESP block after surgery (Group 2).

Study Arms (2)

group 1

OTHER

Following induction of anesthesia, ESP block will be performed before the surgery begins

Other: erector spine plane block

group 2

OTHER

An ESP block will be performed before waking the patient at the end of surgery.

Other: erector spine plane block

Interventions

erector spine plane block OTHER

After anesthesia and surgical procedures, bilateral ESP block will be applied under ultrasonography guidance from the midline 3 cm lateral from the T10 level. After cleaning the area with povidone-iodine before the block, the T10 transverse protrusion will be determined using a linear ultrasound probe. Local anesthetic will be applied between the transverse process and the erector spinae muscle with the help of an insulated needle designed for peripheral block procedures. The location of the needle will be confirmed by hydrodissection with physiological saline without local anesthesia. After the location of the needle is confirmed, 20 ml of LA and saline mixture will be applied and the same process will be repeated in the contralateral side. Of the total 40 ml LA, 20 ml will consist of bupivacaine 0.5% (MARCAİNE), 10 ml will consist of lidocaine 2% (Aritmal), and 10 ml will consist of physiological saline.
