In April, we reported about ropivacaine being injected IV and directed to it's site of action by magnetic nanoparticles; just too interesting to pass by. Well, in case you were as intrigued by this development as we here at Anesthesia Insights were, here is the citation for the full journal article that has since been published:
Anesth Analg 2014;118:1355–62. Nanoanesthesia: A Novel, Intravenous Approach
to Ankle Block in the Rat by Magnet-Directed Concentration of Ropivacaine-Associated Nanoparticles.
