INTERACTIVE REGIONAL ANESTHESIA has established itself as the best-selling CD-ROM on Churchill Livingstone's list. The disk employs movies, videos, and spoken narration to illuminate the anatomical and practical aspects of regional anesthesia. Residents and practitioners are presented with a dynamic guide to the placement and administration of neural blockade. The new edition contains additional illustrations (including 3-D animations), a new chapter on pain syndrome, and a new Q & A self-assessment section.
