ANESTHESIOLOGY
The anesthesiology department at King Animal Hospital works closely alongside all other hospital departments and clinicians to provide safe, effective, and pain-free sedation and anesthesia for your pet. Most diagnostic and many therapeutic procedures require your pet to be immobilized when in hospital to undergo care, so our board-certified anesthesiologists, Dr. Rodrigo Aguilera and Dr. Annatasha Bartel, personally work with the anesthesiology veterinary technicians to provide the safest and most efficient protocols for either sedating or anesthetizing your beloved pet.
