Emergency & Critical Care

Veterinary Emergency and Critical Care is a veterinary specialty that could save your pet's life!

If your pet should become injured, or suddenly develop an acute, life threatening disease, he or she will need prompt emergency care. In addition to needing initial emergency treatment, many days may be needed for the disease process to run its course before recovery occurs. During this time, close monitoring and life support measures in the intensive care unit (ICU) may be needed. A vigilant team lead by a veterinarian who is specialty trained in emergency and critical care will improve the quality of care your pet receives.

Does this involve additional training beyond their veterinary training?

What is a specialist in veterinary emergency and critical care?

A specialist in emergency and critical care is a specially trained veterinarian who is dedicated to treating life-threatening conditions. Yes, they do have additional training! They must first be a graduate of a recognized veterinary school, then receive a minimum (or equivalent) of 3 additional years of intense training in emergency, surgery and critical care through completion of an American College of Veterinary Emergency and Critical Care (ACVECC)-approved training program.

This intense program is referred to as a residency in emergency and critical care and focuses on the most up-to-date techniques for diagnosis and treatment of life-threatening disease processes in an emergency, and for the critical time while the animal is recovering. The emergency and critical care residency is supervised by mentors who have been through similar training programs and are themselves board-certified Diplomates of the American College of Veterinary Emergency and Critical Care (DACVECC).

Once the veterinarian has completed these years of specialty residency training, the individual must then pass a tough board -certification examination given by the ACVECC. Upon successful completion of the training and passing of the examination, the veterinarian is a Diplomate of the ACVECC, is termed a specialist, and is board-certified in veterinary emergency and critical care.
