Moderate to severe pain following surgery represents a major problem for patients, occurring in up to 80% of cases [Laminectomy is a common surgery for patients suffering from spinal canal stenosis in which the lamina, the posterior part of the vertebra, is removed for pain and disability relief. Patients experience severe postoperative pain, usually within the first 12 hours. This pain is caused by postoperative irritation of the posterior horn neurons due to surgery-related tissue damage. Reducing postoperative pain decreases mortality, ensures early patient movement, and increases patient satisfaction [While spinal anesthesia has replaced general anesthesia in many surgeries (e.g., caesarean section), regional blocks and fascial plain blocks feature fewer overall side effects and, in some cases, similar or even better analgesic effects. These procedures have therefore been proposed as reasonable alternatives to systemic narcotics and spinal anesthesia [The erector spinae plane (ESP) block is a fascial plain block that can relieve neuropathic chest pain, postoperative pain, and posttraumatic pain. First described in 2016, this technique represents a safe, simple, promising, and well-performing alternative to the neuraxial block for various surgeries. In addition, this block reduces the risk of direct spinal cord injury, epidural hematoma, and central nervous system infection [Although many studies have been conducted on the ESP block for different types of surgery, the complications must be examined more closely. In addition, methods are needed to optimally test movement and sensory changes depending on the block's location [
