    noci-associations are excluded can be described only by coining a new word. That word is ‘anoci-association.’ “The difference between anesthesia and anoci-association is that, although inhalation anesthesia confers the beneficent loss of consciousness and freedom from pain, it does not prevent the nerve impulses from reaching and influencing the brain, and hence does not prevent surgical shock nor the train of later nervous impairments so well described by Mumford. Anoci-association is accomplished by a combination of special management of patients (applied psychology), morphine, inhalation anesthesia, and local anesthesia. “ In operations under inhalation anesthesia the nerve impulses from the trauma reach every part of the brain—the cerebrum that is apparently anesthetized as well as the medulla that is known to remain awake—the proof being the physiological exhaustion of and the pathological change in the nerve cells. Under ether anesthesia the damage is at least four times greater than under nitrous oxide. Inhalation anesthesia is, therefore, but a veneer, a mask that ‘covers the deep suffering of the patient.’ The cause of the exliaustion of the brain is the discharge of nervous energy in a futile effort to energize the paralyzed muscles in an effort to escape from the injury just as if no anesthetic had been given. The exhaustion is, therefore, of the same nature as that from over- exertion. “But if the nerve paths connecting the field of operation and the brain be blocked, then there is no discharge of nervous energy from the trauma, and consequently no exhaustion, however severe or prolonged the operation.” HEMORRHAGE Hemorrhage denotes the escape from the bloodvessels of all the constituents of the blood. The recognized forms are: Arterial, venous, ca])illary, mixed, hemorrhage ])cr diapcdism, i. e., dia- pedesis and extravasation through intact vessels; and hemorrhage per rhexin, i. e., by actual rupture of the vessel.
