Lumbar spinal surgery is one of the operations performed for the treatment of leg and back pain. Severe pain may occur at postoperative period in patients following lumbar fusion surgery. Postoperative effective pain treatment provides early mobilization and shorter hospital stay, thus complications due to hospitalization such as infection and thromboembolism may be reduced.~Parenteral opioids are generally preferred in the management of acute postoperative pain. However opioids have undesired adverse events such as nausea, vomiting, itching, sedation and respiratory depression (opioid-related adverse events). Regional anesthesia techniques may be preferred as the use of ultrasound (US) increases in daily anesthesia practice.~The ultrasound(US) guided erector spina plan block (ESPB) is injected with a local anesthetic into the deep fascia of the erector spinae. Visualization of sonoanatomy with US is simple and the spread of local anesthetic solution can be seen easily the deep fascia of the erector spinae. In the literature, it has been reported that ESPB provides effective analgesia after lumbar spine surgery. The surgical team visualizes the transverse processes and erector spina muscle during surgery. The erector spina plane block can be performed by administering local anesthetic solution between the transverse process and the erector spina muscle.~The aim of this study is to compare US-guided ESPB and surgical infiltrative ESPB for postoperative analgesia management after lumbar spinal fusion surgery. The primary aim is to compare perioperative and postoperative opioid consumption and the secondary aim is to evaluate postoperative pain scores (VAS), adverse effects related with opioids (allergic reaction, nausea, vomiting).
