Objective To investigate the diagnosis and treatment method of acute respiratory distress syndrome (ARDS) caused by severe chest traumain. Methods Complicated 89 cases in our hospital from July 2007 to February 2015 with severe chest trauma in patients, among which 21 cases with acute respiratory distress syndrome (ARDS), the diagnosis, treatment were analyzed and summarized. Through the comparison of oxygen partial pressure (PaO2), partial pressure of carbon dioxide (PaCO2), oxygen index (PaO2/FiO2) before and after treatment, and were given thepatients to maintain respiratory tract unobstructed, through compared the change patient vital signs to value treatment effect evaluation. Results After treatment, PaO2 increased, PaCO2 decreased, PaO2/FiO2 increased significantly, there were significant differences compared with those before the treatment (P<0.05); in 21 cases, 6 cases were complicated with pneumonia appears, and they were recovered after symptomatic treatment; of which 2 cases died, 1 case of death due to excessive blood loss, also 1 case gave up the treatment.
