A longtime standard for military healthcare personnel, the second edition of Military Advanced Regional Anesthesia and Analgesia Handbook (MARAA) has been thoroughly revised and updated. Although the MARAA handbook initially gained its reputation as a useful resource for managing pain associated with battlefield trauma, its beautifully illustrated step-by-step guidance provides pertinent and practical guidance for managing vital acute pain services in all civilian and military clinical settings. Opening chapters review equipment, local anesthesia and additives, and physics of ultrasound and nerve stimulation. Much of the book is devoted to step-by-step guidance on performing various regional anesthesia nerve blocks organized by pertinent neuroanatomy, use of nerve stimulation, and use of ultrasound. The concluding group of chapters discusses organization of the acute pain service and staff, a review of multidisciplinary care, basics of pediatric regional anesthesia, first-aid acupuncture, and more.
