This guide to the principles of anesthesia administration in animals combines user-friendly coverage of essential information with an outstanding illustration program and improved readability. Anesthesia and Analgesia for Veterinary Technicians, 4th Edition prepares you to administer anesthesia with information on pre-anesthetic preparation of the patient, induction procedures, monitoring animals' vital signs during the anesthetic period, and postoperative care. Expert authors John A. Thomas, DVM, and Phillip Lerche, BVSc PhD, Dipl ACVA, also include discussions of actions and side effects of anesthetic agents, the physiology of respiration, heart rate and blood pressure, emergency response, anesthetic equipment, and specialized techniques.
