TY - CHAP M1 - Book, Section TI - Optimizing Ultrasound Image A1 - Hadzic, Admir Y1 - 2021 N1 - T2 - Hadzic's Peripheral Nerve Blocks and Anatomy for Ultrasound-Guided Regional Anesthesia, 3e AB - Optimization of the ultrasound (US) image is important to improve the visualization of the relevant anatomy during US-guided peripheral nerve blocks (PNBs). Because a nerve block is an injection of local anesthetic (LA) into a tissue space that contains the nerve, it is often more practical and easier to identify the interfascial tissue space containing the nerve than the nerve(s) to be blocked. Optimizing the US image requires knowledge of how the US machine operates and adequate training in image acquisition. In this chapter, we describe standardized scanning steps, including the selection of sonographic modes, adjustment of function keys, essential transducer maneuvers, and interpretation of artifacts to optimize the US view and guide the needle toward the target.
