DEEP VENOUS THROMBOSIS IN THE TRAUMA PATIENT

The incidence of deep venous thrombosis (DVT) in the trauma population and those risk factors which affect its development remain an enigma. We prospectively studied 100 trauma patients admitted to a Level I trauma center with duplex scans throughout their hospitalization. Fifteen patients (15%) developed DVT. The remaining 85 patients (85%) had no evidence of DVT during their hospitalization. The two groups were similar in sex ratio, Glascow coma scale, trauma score, and type of injury. Fourteen patients (93%) with DVT had been given prophylactic treatment with 5,000 units of Heparin subcutaneously q12h, and 36 patients (42%) without DVT were similarly treated. The data in this study describe the incidence of DVT (15%) in the trauma population and those patients at most risk for its development. Patients admitted with high Injury Severity Scores and extremity injuries are at most risk for development of DVT.
