Abstract
A novel stellate ganglion sympathetic block needle having a side port positioned at a predetermined distance from the needle tip. The novel stellate ganglion sympathetic block needle allows for an effective stellate ganglion sympathetic block even if the needle is placed such that the needle tip opening is under the anterior longitudinal ligament which results in the needle tip opening being constricted, thereby interfering with the injection of the anesthesia. When this interference occurs, the side port of the novel stellate ganglion sympathetic block needle allows directional injection onto the surface of the anterior longitudinal ligament in order to spread onto the surface of the longus coli muscle toward the stellate ganglion, thereby achieving an effective stellate ganglion sympathetic block.
