Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Preoperative Erector Spinae Plane Block

In the preoperative period, under general anesthesia, after the linear ultrasound (US) probe will be placed 2-3 cm lateral to the L3 spinous process, 15 ml of 0.25% bupivacaine will be injected into the interfacial space below the erector spinae muscle, above the transverse process. The same ESPB procedure was performed on the other side. In total, 30 ml of 0.25% bupivacaine was administered.

Group Type ACTIVE_COMPARATOR

Preoperative Erector Spinae Plane Block

Intervention Type DRUG

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.

Postoperative Erector Spinae Plane Block

In the postoperative period, under general anesthesia, after the linear ultrasound (US) probe will be placed 2-3 cm lateral to the L3 spinous process, 15 ml of 0.25% bupivacaine will be injected into the interfacial space below the erector spinae muscle, above the transverse process. The same ESPB procedure was performed on the other side. In total, 30 ml of 0.25% bupivacaine was administered.

Group Type ACTIVE_COMPARATOR

Postoperative Erector Spinae Plane Block

Intervention Type DRUG

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.
