Objective: To analyze the epidemiological features of severe chest trauma (SCT) and investigate the risk factor of its mortality in the Three Gorges Area of China.
Methods: The clinical data of 1834 SCT patients who were admitted in three hospitals in this area from January 1990 to December 2009 were retrospectively reviewed. Th epidemiological features of SCT were analyzed using a database. Stepwise logistic regression analysis was used to analyze 15 possible risk factors affecting mortality.
Results: The morbidity rates of blunt trauma (68.5% vs. 74.7%,p=0.006) and sharp instrument injury (12.2% vs. 15.9%,p=0.039) showed significant differences before and after 2000. The pre-hospital time [(3.45±2.38)h vs. (2.20±4.39)h,p<0.01] and transfer rate (32.39% vs. 36.80%,p=0.01) significantly improved. The thoracic Abbreviated Injury Scale (AIS)(3.56±0.71vs. 3.43±0.58,p<0.01)score and Revised Trauma Score (RTS)(7.14±2.18 vs. 6.93±1.07,p<0.01) significantly increased. Treatment for pulmonary infection (12.63±4.79 vs. 17.16±6.41,p=0.019) and hemorrhagic shock (2.4±0.75 vs. 3.4±1.34,p=0.008 )was significantly improved. The leading cause of death was hypovolemic shock (59.41%). The independent rik factors of death among these SCT patients included: hemorrhagic shock (B=1.710,OR=1.291,p=0.001), multiple organ dysfunction syndrome (B=3.453,OR=1.028,p<0.001), pulmonary infection(B=2.396,OR=10.941,p<0.001), abdominal organ injury(B=1.542,OR=1.210,p=0.005), and thorax AIS(B=0.487,OR=1.622,p<0.001).
Conclusions: The prevalence of SCT shows an increasing trend in the Three Gorges Area in recent years, but with a decreased rate of complications and improved treatment. Age, complications, thorax AIS, and GCS are useful prognostic indicators.
