PY - 2016 T2 - Anesthesiology Core Review: Part Two Advanced Exam AB - Intravenous regional anesthesia (IVRA) provides anesthesia to either the upper or lower extremity by means of local anesthetic introduction into a peripheral vein. Alternatively named the Bier block, this anesthetic is contraindicated for procedures requiring muscle paralysis, blockade of individual nerves, or prolonged surgical duration. Developed in 1908 by Dr August Bier, the Bier block remains popular due to its ease of use, reliability, and low incidence of complications. It is useful in short, modestly invasive procedures such as carpel tunnel release and ganglionectomy. The duration of the block is predicated on the duration of tourniquet inflation, limiting toxicity risk from longer acting agents; however, tourniquet discomfort precludes Bier blocks for longer procedures. When employed carefully, the Bier block is a safe and reliable method of producing anesthesia.
