The American Society of Anesthesiologists says it is "extremely troubled" to learn that the anesthetic sodium thiopental, or Pentothal, has been removed from the U.S. market after its sole manufacturer ceased production of the drug, according to an ASA release.

Research at Duke University Medical Center in Durham, N.C., suggests anesthesia providers may be able to improve ultrasound imaging of injected anesthetics and perineural distribution, according to a presentation at the 2010 Annual Meeting of the American Society of Anesthesiologists.
