[目的]研究髋关节大手术前深静脉血栓（deep venous thrombosis,DVT）形成的危险因素,为预防DVT的发生提供有效的预测指标。[方法]选取本院行髋关节置换术患者200例,其中发生DVT 78例,未发生DVT 122例,对所有入选患者的临床资料,手术情况、DVT发生的可能危险因素进行收集,通过单因素分析和logistic回归分析筛选出DVT的危险因素。[结果]Logistic回归显示高龄、高BMI、骨水泥使用、全麻是导致DVT发生的危险因素,而术前使用抗凝药物是DVT发生的保护因素。[结论]高龄、高BMI、骨水泥使用、全麻患者行髋关节大手术后容易发生DVT,术前使用抗凝药可以降低术后发生DVT的风险。
[ Objective] To analyze the risk factors for deep venous thrombosis （DVT） before hip joint replacement, and to provide effective predictive factors for the prevention of DVT. [ Methods ] Two hundred patients undergoing hip joint replace- ment in our hospital were enrolled as subjects. Seventy - eight of the patients had DVT. The clinical data, surgical information, and potential risk factors for DVT were collected in those patients. Univariate analysis and logistic regression analysis were used to identify risk factors for DVT. [ Results] The logistic regression analysis showed that old age, high body mass index （BMI）, use of bone cement, and general anesthesia were risk factors for DVT, while preoperative use of the anticoagulant drug was a protective factor for DVT. [ Conclusion ] Patients with old age, high BMI, use of bone cement, or general anesthesia are likely to have DVT after hip joint replacement. Preoperative use of the anticoagulant drug can reduce the risk of DVT after hip joint replacement.
