A fully updated new edition of this practical guide to managing anesthesia in horses and other equids, providing updated and expanded information in a concise, easy-to-read format
Manual of Equine Anesthesia and Analgesia provides practitioners and veterinary students with concise, highly practical guidance to anesthetizing horses, donkeys, and mules. Using a bulleted quick-reference format, this popular resource covers the basic physiological and pharmacological principles of anesthesia, patient preparation and monitoring, and the management of sedation and anesthesia. Chapters written by leading veterinary anesthesiologists contain numerous clinical images and illustrations, case examples, tables, diagrams, and boxed summaries of important points.
Now in full color, the second edition features extensively revised and updated information throughout. New sections cover chronic pain, management of horses undergoing MRI, ventilators, nerve blocks for reproductive surgery, muscle relaxants, various new drugs, paravertebral anesthesia, treatment of pain using acupuncture and physical rehabilitation techniques, and more. Up-to-date appendices contain drug lists and dosages as well as equations related to equine cardiovascular and respiratory systems. This concise, easy-to-follow guide:
- Provides practical, clinically oriented information on anesthetizing equids
- Uses a bulleted format designed for fast access of key information
- Offers step-by-step instructions and diagrams of nerve blocks of the limbs, head, and ophthalmic structures
- Includes new coverage of topics including regulation of extracellular fluid and blood pressure, acid-base disorders, and hemodynamic effects of autonomic drugs
Manual of Equine Anesthesia and Analgesia, Second Edition, remains a must-have resource for all equine practitioners and veterinary students involved with anesthetizing horses.
