Objective To investigate the risk factors for acute respiratory distress syndrome (ARDS) in patients with severe trauma.Methods Clinical data of 308 severe trauma patients admitted to the emergency department of the fourth medical center of PLA general hospital from June 2010 to June 2017 were retrospectively analyzed.And the patients were divided into the observation group (77 cases) and the control group (231 cases) according to whether they suffered from ARDS.Age

thoracic trauma severity (TTS)

basic disease and shock duration were compared between the 2 groups.Univariate analysis and multivariate analysis were used to determine the risk factors of ARDS in patients with severe trauma.Results The severity of chest trauma is correlated with the occurrence of ARDS

and the mechanical ventilation rate in the observation group is much higher than that in the control group

with statistically significant difference (P<0.05).The incidence of pulmonary infection

length of EICU and hospital stay

and mortality of the two groups were statistically significant (P<0.05).Unifactorial analysis showed that shock duration greater than or equal to 4 hours

TTS score greater than or equal to 14 points

complicated with pulmonary infection

and previous history of diabetes were statistically significant between the two groups (P<0.05).Logistic regression analysis showed that TTS score greater than or equal to 14

shock duration greater than or equal to 4 hours and hypoxemia at admission were risk factors for ARDS after trauma (P<0.001)

among which TTS score greater than or equal to 14 was the high risk factor (P<0.01). ConclusionARDS in patients with severe trauma is associated with shock duration

TTS score and hypoxemia at admission.
