Experimental Pulmonary Edema. IV. Pulmonary Edema Accompanying Trauma to the Brain.∗

Summary Experimental pulmonary edema occurs in the rat in a matter of seconds as a result of a blow to the calvaria causing fatal trauma to the brain. This edema is prevented or reduced in degree by agents which produce a deep narcosis and by adrenergic blocking compounds. The mechanism of its production is discussed in relation to other types of experimental pulmonary edema.
