Study: Improved Ultrasound Imaging of Injected Anesthetics on the Horizon

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.

Researchers administered saline injections to a 40-year-old man at the popliteal fossa, supraclavicular brachial plexus and interscalene brachial plexus. They then captured raw radiofrequency data at a rate of 42 frames per second at various stages throughout the injection process.

The researchers concluded that pictures and videos of the injection may provide another tool for regional anesthesiologists to improve distribution of anesthetic around a particular nerve. This could in turn reduce the likelihood of nerve block failure and improve pain management.
