Regional and local anesthesia techniques provide targeted pain relief by numbing specific areas of the body, allowing for surgical procedures without the need for general anesthesia. Local anesthesia, administered through topical application, infiltration, ring blocks, or peripheral nerve blocks, is widely used due to its safety, simplicity, and effectiveness. Regional anesthesia, including spinal, epidural, and nerve blocks, is commonly employed in orthopedic, gynecological, and urological surgeries, as well as for pain management during labor and delivery. Advances in delivery methods continue to expand the clinical applications of these techniques, enhancing patient comfort and reducing recovery times.
