Comparison of Pain Relief After Upper and Lower Lumbar Erector Spinae Plane Block

February 23, 2023 updated by: Ji Hee Hong, Keimyung University Dongsan Medical Center

Comparison of Pain Relief and Spread Level in Upper and Lower Lumbar Erector Spinae Plane Block

The primary endpoint of this study was to identify if eretor spinae plane block (ESPB) has any effect in relieving low back pain or leg pain in lumbar radiculopathy. The secondary endpoint was to compare the number of spread level when upper or lower lumbar ESPB was performed.

Detailed Description

The erector spinae plane block (ESPB) is a less invasive, safer, and technically easy alternative procedure to conventional neuraxial anesthetic techniques. In contrast to common neuraxial techniques such as paravertebral and epidural injections, the ESPB targets an interfascial plane which is far from the spinal cord, root, and pleura. First applied to thoracic neuropathic pain, currently ESPB is being applied to postoperative pain control and includes variable clinical situations. In the abdomen and thoracic wall, thoracic ESPB can be applied for pain control after cardiac surgery, video-assisted thoracic surgery, laparoscopic cholecystectomy, and thoracotomy. Recently, favorable postoperative pain control after lumbar spinal or lower limb surgeries has been reported with lumbar ESPB. In addition, ESPB has also been used for chronic pain conditions in the upper and lower extremities. To investigate the possible mechanism of action of the ESPB, many previous studies have focused on examining the physical spread of the injected agent. Commonly, contrast dye injections in human cadavers have been utilized to assess the spread level. Physical spread level was determined using various methods including direct dissection or sectioning, computed tomography (CT), thoracoscopic inspection, or magnetic resonance imaging (MRI) with radiocontrast injection. Apart from human cadaver studies, physical spread level has been evaluated in alive patients using a variable volume of local anesthetics mixed with radiocontrast. However, these studies are limited by the small number of included patients. Therefore, the exact spread level of injected local anesthetics remains unclear and a study on a large number of patients is still required
