Farm Animal Anesthesia: Cattle, Small Ruminants, Camelids, and Pigs

A completely revised and updated reference for farm animal anesthesia, sedation, and pain management The newly revised Second Edition of Farm Animal Anesthesia: Cattle, Small Ruminants, Camelids, and Pigs is a practical and easy-to-use manual for techniques associated with anesthesia and pain management in farm animal species. The new edition incorporates advances in surgical and diagnostic techniques, with the latest drugs and equipment, updated images, and new technique descriptions added throughout the book. Farm Animal Anesthesia offers additional and updated information on drug combinations and anesthetic techniques relevant to small ruminants and potbellied pigs, reflecting their growing popularity. New chapters and topics on paralytic drugs for complete muscle relaxation, use of ventilators for advanced and complex surgeries, updated local and regional anesthetic techniques, and comprehensive standing surgery and diagnostic procedures have been added. Readers will also benefit from access to a companion website with video clips demonstrating local and regional anesthetic techniques described within. The book also includes: A thorough introduction to general preanesthetic considerations for ruminants, camelids, including alpacas and llamas, and potbellied pigs A comprehensive exploration of commonly used preanesthetics and injectable anesthetics, including anticholinergics, sedatives, tranquilizers, analgesics, and injectable anesthetics Practical discussions of standing sedation and chemical restraint, including new drug combinations for reliable restraint and remote drug delivery In-depth description of the use of neuromuscular blocking drugs and monitoring in farm animals Complete review of regulatory and legal considerations of anesthetics and analgesics used in farm animals Farm Animal Anesthesia is an indispensable resource for farm animal practitioners, veterinary surgeons, veterinary anesthetists, and researchers, as well as for veterinary students and residents in surgery and anesthesia.
