Regional anesthesia is a fast-growing field, fuelled by the application of ultrasound technology over the last decade. This book is a technique-oriented guide, which introduces the use of ultrasound technology with practical instruction in the placement of peripheral nerve blocks and continuous perineural catheters. Each procedure is summarized for quick, easy reference, and supplemented by ultrasound images, color photos, and detailed illustrations. Helpful hints and instructions are provided to further optimize block success. Chapters are organized into four sections, focusing on introductory concepts, upper extremity peripheral nerve blocks, lower extremity peripheral nerve blocks and continuous perineural catheters.
