Student Learning Outcomes

  • Describe the steps involved in a pre-anesthetic assessment of a veterinary patient and correctly identify the risk category of that patient.
  • Evaluate a case study of a dog or cat during an anesthetic procedure.

Description

Principles and practice of veterinary anesthesia for the veterinary technician. Anatomy and physiology of the respiratory, cardiovascular, and nervous systems relevant to anesthesia. Pharmacology, indications, contraindications and adverse effects of common pre-anesthetic and anesthetic agents. The veterinary technician's role in patient assessment, preparation, induction, monitoring, maintenance, and recovery of anesthesia. Sedation, analgesia, general anesthesia, and local anesthesia techniques will be discussed. Intended for students in the Veterinary Technology Program; enrollment is limited to students accepted in the program, or by special permission of the instructor.

Course Objectives

The student will be able to:
A. List the objectives and expectations for the course, and briefly describe the history of veterinary anesthesia, as well as the common definitions and indications for sedation, analgesia and anesthesia.
B. Describe the role of the veterinary technician in the anesthetic event.
C. Describe the steps of a thorough pre-anesthetic evaluation of a veterinary patient and develop a comprehensive anesthetic plan.
D. Develop a nursing care plan.
E. Identify and explain the function of each of the components of the veterinary anesthesia machine.
F. Recognize, critically evaluate, and respond appropriately to common anesthetic problems and emergencies.
G. Explain how anesthesia affects the nervous system.
H. Explain how anesthesia affects the cardiovascular system.
I. Explain how anesthesia affects the respiratory system.
J. Know and articulate the general principles of inhalation anesthesia.
K. Discuss the indications for manual and mechanical ventilation techniques.
L. Describe the indications and common protocols for injectable agents.
M. Explain the common protocols and procedures used for the canine and feline.
N. Explain the common protocols and procedures used in the equine, bovine, ovine, caprine, and porcine.
O. Explain the principles of local anesthesia and list the common protocols and procedures.
P. Explain the principles of rabbit and rodent anesthesia and list the common protocols and procedures.
