髋臼及骨盆骨折患者术前深静脉血栓形成的危险因素

目的：探讨髋臼及骨盆骨折患者术前深静脉血栓（DVT）形成的危险因素。方法：选取我院2012年4月至2014年4月收治的194例髋臼及骨盆骨折患者为研究对象，通过影像学检查结果分为深静脉血栓组（A 组，n ＝24）和非深静脉血栓组（B 组，n ＝170）。回顾性分析两组患者临床资料，用Logistic 回归分析深静脉血栓形成的危险因素。结果：①A 组患者一般临床资料与 B 组患者对比差异具有统计学意义（P＜0．05）；②Logistic 回归分析中可知，年龄≥45岁、合并系统疾病、卧床时间长、血清 D－二聚体水平≥0．5mg ／L 均为患者术前危险因素（P＜0．05）；抗凝预防措施能有效预防术前 DVT 形成，为相关保护因素（P＜0．05）。结论：患者年龄、高凝状态、合并创伤、卧床时间长短及血清 D－二聚体水平等因素直接影响髋臼与骨盆骨折患者术前 DVT 形成，对于高危患病人群，应做好筛查工作，术前抗凝预防治疗可降低 DVT 形成几率。

The Risk Factors of Presence of Preoperative Deep Venous Thrombosis in Patients with Acetabular and Pelvic Fracture

Objective: To investigate the risk factors of preoperative deep venous thrombosis of patients with acetabular and pelvic fracture .Methods: 194 cases of acetabular and pelvic fracture patients treated in our hospital from April 2012 to April 2014 were selected as the research object , and they were divided into deep vein thrombosis group ( group A, n=24 ) and non DVT group ( group B, n=170 ) by imaging exami-nation.Results:① There's statistical significance in general data of patients of groups A and patients in group B (P<0.05); ② Logistic regression analysis showed and age over 45 years, with system disease, long bed time, serum D-two dimer level ≥ 0.5 mg/L patients were risk factors for preoperative patients with fracture reduction (P<0.05).Anticoagulant prophylaxis measures can effectively prevent the formation of preoperative DVT, as protective factors, (P<0.05).Conclusion: The age of patients, hypercoagulable state, combined with injury, the duration of bed rest and the serum D -two dimer level and other factors directly affect the ace -tabulum and pelvis fracture patients before DVT formation , for high-risk population screening,should do the screening work, preoperative anticoagulant prophylaxis can reduce the DVTformation .
