[Diagnosis of "shock lung"].

The dynamic x-ray changes in the lungs of 57 cases with severe non-thoracic traumas and shock were studied. 18 patients showed a symmetric injury to the lung, increase of the size of the pulmonary roots and dramatic markedness of the vascular picture within the first hours after trauma. The small peripheral vessels dilated and became very visible. Alveolar oedema was found in 39 patients 6 to 12 hours after trauma. In 11 patients alveolar oedema progressed to massive oedema. Two phases were found in the development of alveolar oedema: microfocal and macrofocal ones.
