History of the Development of Anesthesia for the Dolphin

Abstract

Abstract It is important for academic-minded human anesthesiologists to have an interdisciplinary perspective when engaging in cutting-edge research as well as the practice of human anesthesiology. This was a philosophy promoted by Dr. Robert Dripps, former pioneering Chairman of the Anesthesiology Department at the University of Pennsylvania (Philadelphia, Pennsylvania). Many human and veterinary anesthesiologists as well as biomedical engineers and neuroscientists benefited from Dr. Dripps’s constructive outlook personified in the quest to develop dolphin anesthesiology. The motivation to anesthetize dolphins came from the fact that scientists and physicians wanted to study the brain of the dolphin, a brain as large as man’s. Also, investigators wanted to develop anesthesia for the dolphin in order to study the electrophysiology of the dolphin’s highly sophisticated auditory system, which facilitates the dolphin’s amazing echolocation capability. Dolphin anesthesia involves a complex matter of unique neural control, airway anatomy, neuromuscular control of respiration, and sleep behavior.
