全髋关节置换术后发生深静脉栓塞的危险因素分析及干预对策

目的分析全髋关节置换术后发生深静脉栓塞(DVT)的危险因素,针对性制定干预对策。方法回顾性分析本院于2007年10月至2012年10月收治的全髋关节置换术患者302例,分为血栓组(40例)和非血栓组(262例)。统计两组患者的临床资料,量化和赋值相关危险因素,通过统计学软件进行单因素和多因素分析。结果单因素分析显示,年龄、女性、三酰甘油(TG)大于或等于1.7mmol/L、使用骨水泥以及手术时间过长为发生DVT的独立危险因素(P<0.05);而多因素分析则说明,使用骨水泥危险性最大(OR=9.247),其他因素依次为年龄(OR=6.781)、性别(OR=6.374)、TG(OR=5.647)、手术时间(OR=4.247)。结论全髋关节置换术后发生DVT与多种因素关系密切,临床上应针对性的开始围术期干预,确保患者的手术疗效。

Analysis of risk factors and intervention strategy of deep venous thrombosis after replacement of total hip

Objective To analyze the a risk factors and intervention strategy of deep venous thrombosis（DVT）after replacement of total hip（RTH）.Methods 302cases of patients treated by RTH in this hospital during Oct.2007and Oct.2012were divided into DVT group（40cases）and non-DVT group（262cases）.Risk factors were identified and analyzed by single factor and multiple factors analysis of clinical data.Results Single factor analysis indicated that age,women,triglyceride（TG）level higher or equal with 1.7mmol/L,usage of bone cement and operation for a long time were independent risk factors of DVT（P0.05）.Multiple factors analysis indicated the risk factors,ranged by odds ratio（OR）,were usage of bone cement（OR=9.247）,age（OR=6.781）,gender（OR= 6.374）,TG level（OR=5.647）and operation time（OR=4.247）.Conclusion DVT after RTH might be closely correlated with many factors,and perioperative intervention should be strengthened to ensure the therapeutic effect of RTH.
