Book excerpt: This full-color text/atlas describes all of the nerve blocks for which ultrasound guidance has proved efficacious, including upper and lower limb blocks. The chapter organization is similar to Chelly's Peripheral Nerve Blocks book: each block is described by concise text covering the indications for use, necessary equipment, anatomic landmarks, approach, and technique. The blocks are richly illustrated by ultrasound stills and relevant anatomy. A companion Website will have video modules on 1. principles of sonography, including how to turn on the machine, set up the transducers, move the transducers, change the contrast, depth, frequency and dynamic range compression settings, how to use color Doppler flow imaging and align the needle with the beam and 2. ultrasound-guided blocks of the interscalene, supraclavicular, infraclavicular, axillary, femoral, subgluteal, popliteal, and caudal regions.
