目的：分析髋关节置换术患者深静脉血栓形成的危险因素，探讨Autar量表风险评估的应用价值。方法：选择2015年1月～2016年12月收治的髋关节置换术手术患者101例为研究对象，采用单因素及多因素Logistic回归分析的方法分析髋关节置换术患者深静脉血栓形成的危险因素，采用Autar量表评估深静脉血栓形成危险程度。结果：101例髋关节置换术患者中，术后发生深静脉血栓15例，发生率14.85%。单因素分析表明，发生深静脉血栓形成患者女性、合并疾病（高血压、糖尿病、心脑血管疾病）明显多于无深静脉血栓形成者，术后早期活动、术后使用抗凝药明显少于无深静脉血栓形成组，年龄明显大于无深静脉血栓形成者；多因素Logistic回归分析表明，女性、高龄、合并高血压、糖尿病、心脑血管疾病是髋关节置换术后深静脉血栓发生的危险因素，术后早期活动、术后应用抗凝药物是预防深静脉血栓形成的保护因素；高度风险患者深静脉血栓形成发生率明显高于低度风险组、中度风险组，中度风险组深静脉血栓形成发生率明显高于低度风险组。结论：髋关节置换术患者深静脉血栓形成发生率较高，与性别、年龄、合并疾病明显相关，应加强对患者深静脉血栓形成的风险评估，给予预见性及针对性护理干预策略，以减少深静脉血栓形成发生率。

 Objective To analyze the risk factors of deep venous thrombosis in patients undergone hip replacement, and to investigate the application value of Autar Scale risk assessment. Methods A total of 101 cases of patients admitted to hospital from January 2015 to December 2016 and undergone hip replacement were selected as the research objects. The methods of single factor and multi-factor logistic regression analysis were used to analyze the risk factors of deep venous thrombosis in those patients, and Autar Scale was used to assess the risk degree of deep venous thrombosis. Results Among the 101 cases of patients, 15 cases had postoperative deep venous thrombosis, with the incidence rate of 14.85%. Single factor analysis showed that the incidence rate of deep venous thrombosis in female patients and patients with complicating diseases (hypertension, diabetes, cardiovascular and cerebrovascular diseases) was significantly higher than that of patients without deep venous thrombosis; the incidence rate of patients with postoperative early activities and postoperative use of anticoagulants was significantly lower than that of patients without deep venous thrombosis; the incidence rate of aged patients was significantly higher than that of patients without deep venous thrombosis. Multi-factor logistic regression analysis showed that female, advanced age, complicated hypertension, diabetes and cardiovascular and cerebrovascular disease are risk factors of deep venous thrombosis after hip replacement, postoperative early activities and postoperative use of anticoagulants are protective factors that prevent deep venous thrombosis; the incidence rate of deep venous thrombosis in high risk patients was significantly higher than that of low risk and medium risk patients; the incidence rate of deep venous thrombosis in medium risk patients was significantly higher than that in low risk patients. Conclusion The incidence rate of deep venous thrombosis in patients undergone hip replacement is high, and it is significantly correlated with gender, age and complicating diseases. The risk assessment on deep venous thrombosis should be strengthened, and predictable and targeted nursing intervention strategies should be proposed to reduce the incidence rate of deep venous thrombosis.
