The Sonosite SII ultrasound machine provides clear visualization of needle and nerve during block placements, allowing precise placement of local anesthetic with minimal patient discomfort. Interscalene nerve blocks with Sonosite II permit the placement of local anesthetic around the roots or trunks of the brachial plexus at the level of the C6 vertebral body between the anterior and middle scalene muscles. Anesthesiologist Dr. David Auyong MD of Seattle, Washington here reviews scanning techniques and sonographic landmarks for this procedure which is typically performed to provide anesthesia or analgesia for surgery of the shoulder and upper arm.

The Sonosite SII ultrasound machine supports regional anesthetic techniques used during supraclavicular blocks – serving as an alternative or adjunct to general anesthesia needed for postoperative pain control for upper extremity surgeries (mid-humerus through the hand). Anesthesiologist Dr. David Auyong MD of Seattle, Washington here reviews scanning techniques and sonographic landmarks for the ultrasound guided nerve block. Dr. Auyong highlights patient position, the type of transducer used, the needle position and injection technique. The ability to image the plexus, rib, pleura, and subclavian artery increases safety due to improved monitoring of anatomy and needle placement.
