This comprehensive, authoritative text presents the scientific foundations and clinical practice of neural blockade in both regional anesthesia and the management of pain. The descriptions and illustrations of pain mechanisms are considered classic examples. The Fourth Edition has been refined for clarity and flows logically from principles and pharmacology, to techniques for each anatomic region, to applications. This edition has two new co-editors and several new chapters on topics including neurologic complications, neural blockade for surgery, treatment of pain in older people, and complications in pain medicine.
