Efficacy of Surgical Injection Lumbar Erector Spinae Plane Block

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.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 aim of this study is to compare US-guided ESPB and surgical infiltrative ESPB for postoperative analgesia management after lumbar spinal fusion surgery.
