The Effect of Spinal Flexion in the Lateral Decubitus Position on the Unilaterality During Spinal Anesthesia

May 26, 2012 updated by: Jin-Tae Kim, Seoul National University Hospital
For unilateral spinal block, spinal local anesthetics should take effect on the spinal nerves of one side. With full flexion of the spine, the cauda equina becomes tightened and hangs in the middle of the subarachnoid space. This study was performed to assess if flexion of the vertebral column facilitates unilateral spinal anesthesia.
