Ultrasound-Guided Regional Anesthesia A1 - Dizdarevic, Anis A1 - Yap, Steven A1 - Garvin, Eugene A1 - Marshall, Cameron A2 - Schrope, Beth PY - 2014 T2 - Surgical and Interventional Ultrasound AB - The use of ultrasound guidance for peripheral nerve blocks in regional anesthesia and pain management offers several advantages over traditional methods including the paresthesia technique and neural stimulation technique. Studies in regional anesthesia and pain medicine seem to indicate that ultrasound guidance can decrease the time required to perform a nerve block and hasten the onset of block, thus potentially improving efficiency between operative cases. Patient discomfort may also be reduced as ultrasound decreases the number of attempted needle passes while performing a block. Direct visualization of neural and vascular structures, including the use of Doppler and visual confirmation of local anesthetic spread around the target nerves, could decrease the risk of intravascular injection, intraneural injection, injury to the lung, or other nearby vital structures.
