In recent years, regional anesthesia techniques have also been frequently applied to patients for pain relief. Erector spinae plane block (ESPB), is among the regional anesthesia techniques frequently used in lumbar spine surgery. General anesthesia (GA) is the main method of anesthesia for lumbar spine surgery. However, GA can only inhibit the projection system of the cortical limbic system or hypothalamic cortex. GA cannot completely block the transmission of peripheral noxious stimulus to the central nervous system and cannot effectively inhibit the intraoperative stress response. With the addition of peripheral blocks such as ESPB, lower remifentanil consumption, and more stable hemodynamics are expected by providing preemptive analgesia in patients. As a result of all these; it was aimed to compare the intraoperative remifentanil consumption of patients who underwent preoperative ESPB in patients who will undergo lumbar spine surgery resection under GA with those who underwent postoperative ESPB.

Erector spinae plane block will be performed bilaterally, under US guidance, before the surgical operation, after the induction of anesthesia, and when the patient is placed in the prone position.
Erector spinae plane block will be performed unilaterally, under US guidance, after the surgical operation, under general anesthesia, and when the patient is placed in the prone position.
Ankara Etlik City Hospital
Yenimahalle, Ankara, Turkey (Türkiye)
Intraoperative remifentanil consumption
The amount of remifentanil that patients need to maintain anesthesia during the intraoperative period will be recorded.
Time frame: During the intraoperative period
Mean arterial pressure
Mean arterial pressure values will be recorded before anesthesia, before surgical incision, after surgical incision at the 5th, 30th, 60th, 90th, 120th minutes, and after general anesthesia.
Time frame: Perioperative period
Heart rate
Heart rate values will be recorded before anesthesia, before surgical incision, after surgical incision at the 5th, 30th, 60th, 90th, 120th minutes, and after general anesthesia.
Time frame: Perioperative period
Pain scores
Pain will be assessed at rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). Pain assessment will be done at the 1st, 2nd, 6th, 12th, and 24th hours after surgery.
Time frame: First 24 hours after surgery
