Since heart-lung machines, also known as cardiopulmonary bypass (CPB), had not been invented yet, stopping the heart meant stopping blood circulation to the whole body, including the brain. (wikipedia.org)
The advent of cardiopulmonary bypass in the United States during the 1950s allowed the heart to be stopped for surgery without having to stop circulation to the rest of the body. (wikipedia.org)
Cardiopulmonary bypass machines allow blood circulation and cooling to continue below the temperature at which the heart stops working. (wikipedia.org)
In 1959, using cardiopulmonary bypass (CPB), Barnes Woodhall and colleagues at Duke Medical Center performed the first brain surgery using DHCA, a tumor resection, at a brain temperature of 11 °C and esophageal temperature of 4 °C.
