For over a century USC’s Department of Anesthesiology has contributed to the art and science of anesthesiology. One of our most storied faculty, Dr. Arthur Guedel, codified the stages of anesthesiology and designed the “Guedel airway” which was in use for nearly 90 years. Dr. Guedel’s innovations were based on his clinical practice, setting the approach for the department’s ongoing contributions to our profession.
