The role of World War II and the European theater of operations in the development of anesthesiology as a physician specialty in the USA.

World War II was a time of growth and development of anesthesia as a physician specialty. Wartime training exposed neophyte physician-anesthetists to role models who showed the potential of anesthesiology and to the richness of practicing anesthesia. Wartime anesthesia required dexterity, imagination, and pluck, and surgeons and other physicians were suitably impressed. Drawing historical conclusions about cause and effect is hazardous. Recognized and unrecognized biases, preconceived notions, and the quality and type of resources available affect writers. With this in mind, consider how the effects of World War II on the growth of physician anesthesia loosely parallel the growth of anesthesia in Great Britain during the 19th century. Anesthesia became a medical profession in Great Britain because of the interest and support of physicians and the complexity of administering chloroform anesthesia. Similarly, World War II physician-anesthetists showed they could provide complex anesthesia care, such as pentothal administration, regional anesthesia, and tracheal intubation, with aplomb and gained the support of surgical colleagues who facilitated their growth within a medical profession. They returned to a medium ready to support their growth and helped to establish the medical profession of anesthesiology in the United States.
