ABSTRACT

Objective To identify the risk factors for deep vein thrombosis(DVT) in the lower extremities during hospitalization for acute spinal cord injury(SCI).Methods Retrospective data analyses were performed for 49 SCI patients admitted within a week after they were diagnosed.The patients were divided into a DVT-free(n =40) group and a DVT group(n =9) according to their lower limbs' color Doppler ultrasound results.And the subjects' gender,age,chronic diseases (diabetes,hypertension and hyperlipidemia,etc.),complications (pulmonary infection,urinary tract infections and pressure sores,etc.),the history of cancer,smoking history and lower extremity fractures were recorded.Intermittent pneumatic compression treatment,the early rehabilitation intervention,antithrombotic therapy,history of venous catheterization,operative intervention,blood transfusion history,muscle strength of lower extremity and time from onset to being transfered to rehabilitation department were also recorded Single factor analysis,was conducted,followed by Binary logistic regression to pick out the risk factors for DVT.Results The result of the binary logistic regression analysis showed that gender (OR 6.87 ; 95％ CI 1.09-43.22 ;P ＜ 0.05) and intermittent pneumatic compression treatment (OR 12.47 ; 95％ CI 1.09-142.36 ; P ＜ 0.05) were significant predictors of DVT.Conclusion Gender and intermittent pneumatic compression treatment are related with DVT risk for patients with acute SCI.
