• Registration Number: NCT06963424
• Lead Sponsor: Keimyung University Dongsan Medical Center

Brief Summary

The primary endpoint of this study is to compare the pain relief and peripheral perfusion index when local anesthetics injected in different final target area during lumbar erector spinae block The secondary endpoint of this study is to compare the procedure related pain

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. The final target area of ESPB of cervical, thoarcic, and lumbar regiona is transverse process. Once the needle contact the tip of the transverse process, local anesthetics is injected subsequentely. However, contacting the bony structure with the needle can generage procedure related pain. If ESPB can be performed without touching the transverse process, the satisfaction of patient would be increased. Actually, intertransverse ligament, which is visibe by ultrasound, is present between transverse process. Therefore, if local anesthetics is injected after targeting intertransverse ligament, same effect of pain relief with tarting of transverse process of ESPB is uncertain
