A Brief History of Intrathecal Therapy C. Douglas Stewart, PA/C MBA Dir. of Interventional Pain Medicine Center For Pain Relief Charleston, West Virginia
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
Followed on His HeelsAugustus Bier • About 1898 • Injected his Assistant • Injected 6 patients • Oh, and had his assistant inject him. • Mixed results
Next UP • About 1900 • Rudolph Matas • Mixed Morphine and Cocaine and got more stable results
Grafton Love • About 1935 • Neurosurgeon at Mayo Clinic • Developed a flexible needle • And used 5fr lacquered silk Catheter • Got infected • Not reproducible
William Leonard • About 1940 • Philadelphia Surgeon • Flexible needle and used continuous infusion
New Needle • About 1944 • Edward B. Tuohy • Developed Tuohy Needle
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
Another Advance, The use of plastic catheters was first described by Flowers in 1949. The first polymer (plastic)was polyethylene, which had been introduced as biomaterial for epidural catheters. but why now??
What Happened Between 1941 and 1945? World War 2
Set The Stage • Manufacturing • New Plastics • Techniques • Chemistry • Better Understanding Of How Drugs Worked • New Drugs • NEW SCIENCE ABOUNDS
And The Race Is On • 1960 ChohHao Li identified beta-endorphin • More work followed • 1973 Candace Pert & Solomon Snyder identify opiate receptor • 1977 Tony Yaksh & Thomas Rudy Study direct spinal action of narcotics in producing analgesia in rats • 1979 Epidural Morphine in Treatment of Pain (10) • 1981 First Report of continuous infusion of spinally administered opioiods with constant delivery pump • 1982 numerous reports of improvement of both epidural and intrathecal routes constant delivery pump
Still Racing On • 1986 High Dose Morphine Produced Hyperesthesia • 1987 Chronic Intrathecal morphine for intractable pain (43) • Pump Technology Grew • Continuous infusion VS. Programmable • Each iteration gets better
What’s Next • I truly do not know • Sets stage for where we are now
