  1. A Brief History of Intrathecal Therapy C. Douglas Stewart, PA/C MBA Dir. of Interventional Pain Medicine Center For Pain Relief Charleston, West Virginia

  2. The Beginning Leonard Corning Followed on Karl Koller’s work published in 1884 - cocaine 1885 the first neuraxial anesthetic Gave rise to the idea that it might be possible to treat pain, acute surgical pain

  3. Followed on His HeelsAugustus Bier • About 1898 • Injected his Assistant • Injected 6 patients • Oh, and had his assistant inject him. • Mixed results

  4. Next UP • About 1900 • Rudolph Matas • Mixed Morphine and Cocaine and got more stable results

  5. Grafton Love • About 1935 • Neurosurgeon at Mayo Clinic • Developed a flexible needle • And used 5fr lacquered silk Catheter • Got infected • Not reproducible

  6. William Leonard • About 1940 • Philadelphia Surgeon • Flexible needle and used continuous infusion

  7. New Needle • About 1944 • Edward B. Tuohy • Developed Tuohy Needle

  8. The Next Few Steps YearDevelopmentClinician 1899 Successful demonstration of spinal anesthesia (Germany) August Bier 1901 Sacral epidural local anesthetic injections to treat chronic pain (Fr) Jean-AnthanaseSicard 1921 Single-shot lumbar epidural anesthesia (Spain) Fidel Page´s-Mirave´ 1933 Single-shot lumbar epidural anesthesia (United States) ArchileMario Dogliotti 1938 Continuous lumbar epidural anesthesia (Romania) EugenBogdanAburel 1944 Continuous lumbar epidural anesthesia (United States) Robert A. Hingson 1949 First report of successful continuous lumbar epidural anesthesia (US)Manuel Martinez Curbelo

  12. Set The Stage • Manufacturing • New Plastics • Techniques • Chemistry • Better Understanding Of How Drugs Worked • New Drugs • NEW SCIENCE ABOUNDS
