    The pathogenesis of shock lung as well as the success of therapy in this condition was studied in 79 cases of extrathoracic trauma. The water-, hemoglobin-, and DNA contents of the lungs were measured in order to determine the extent of edema, the rate of perfusion, and proliferation. The cases were divided into two groups according to whether they had or had not received medical therapy before death. The data from these two groups were compared using statistical methods in which time of survival was especially taken into account. The fluid balance, pO2, pCO2, central venous pressure, pH of the serum, total serum protein and serum creatinine were also studied in these cases. Results of the study are as follows. Three phases of the posttraumatic syndrome of shock-lung could be distinguished: phase I (initial phase): blood perfusion is increased, edema is beginning to form, and medical treatment has not yet begun. Phase II (early phase = sydrome of early respiratory failure): pulmonary edema is developing rapidly while perfusion is decreasing. Phase III (late phase = syndrome of late respiratory failure): proliferative changes predominante and the edema is still increasing. The mean weight of the lungs was 397 g (s = 170) in phase I, 774 G (S = 361) In phase II, and 1124 g (s = 310) in phase III. The survival times correlated significantly and positively with the amount of water and DNS in the lungs and significantly and negatively to the amount of hemoglobin in the lungs. Thus, increasing pulmonary edema and increasing proliferative changes occurred with decreasing pulmonary perfusion. This correlation was even noted in groups of patients who had not received medical treatment and whose survival times were short. In treated cases, the fluid balance was significantly and negatively correlated to the total serum protein.
