Video Summary

Beth Ann Clayton presents an overview of vertebral anatomy, focusing on its relevance to neuraxial anesthesia. Central neuraxial blockades involve introducing local anesthesia near the spinal cord using either spinal or epidural methods. Understanding vertebral anatomy—primarily the 33 vertebrae and their distinct curves—is crucial for precise anesthetic placement. This knowledge aids in forming a mental image of vertebral structures, enhancing tactile navigation during procedures. The vertebral column, protecting the spinal cord, is comprised of cervical, thoracic, lumbar, sacral, and coccygeal vertebrae, differing in size and structure to accommodate various physiological roles. Ligaments, including the supraspinous and ligamentum flavum, offer structural support and stability. Neuraxial anesthesia impacts the sympathetic nervous system by blocking nerve conductance and influencing motor and sensory pathways. Clayton emphasizes the importance of anatomy in mitigating risks such as inconsistent anesthetic distribution and facilitating interventions even in complex cases like scoliosis, prevalent in older adults.
