[Dynamics of changes in pulmonary catecholamine content and lipid fatty acid composition in traumatic shock]

The content of noradrenaline in the lungs, pulmonary arteries and veins was found to be reduced at definite stages of traumatic shock. At the same time the level of oleic acids was decreased in pulmonary lipid fractions. The content of adrenaline rose in the pulmonary arteries and veins, and it was high in the blood collected from the right atrium as compared to the blood from the carotid artery. It is assumed that the changes in the content of fatty acids are linked with those occurring in lung catecholamine metabolism.
