Ultrasound-Guided Nerve Blocks T2 Handbook of Critical Care and Emergency Ultrasound YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-160489-5 LK accessanesthesiology.mhmedical.com/content.aspx?aid=56302117 RD 2024/03/29 AB Regional anesthesia provides an alternative to general or local anesthesia, procedural sedation, and parenteral pain management. Conventional anatomic approaches to nerve blocks are imprecise, and success rates vary greatly from one practitioner to another. Electronic nerve stimulation is often used for improved nerve localization, but may not be available outside of surgical suites. In recent years, ultrasound-guided regional anesthesia has gained popularity as an adjunct or alternative to anatomic and nerve stimulation techniques. While simple blocks (eg, a digital block) have long been performed by non-anesthesiologists using the anatomic approach, the more widespread availability of point-of-care ultrasound is providing a safe and effective method to expand the use of nerve blocks in the emergency and critical care setting.
