Spinal anesthesia

In 1899, Dr. Rudolph Matas of New Orleans, Louisiana, anesthetized a patient by "spinal subarachnoid method" for surgery. His report, the first on the subject in the U.S. was "The Growing Importance and Value of Local and Regional Anesthesia in Minor and Major Surgery," which was published in the Journal of the Louisiana state Medical Society (1900). Matas is known as "the Father of Modern Vascular Surgery." Delicate surgery was his forte. In 1888 Matas reported the first known aneurysmorrhaphy worldwide. Also in 1888, Dr. Leonard Corning performed the first spinal block with cocaine, but it was over a decade later when Matas performed the first successful preplanned attempt at intraspinal cocainization.
