低分子肝素联合间歇充气加压预防髋膝关节术后静脉血栓的效果

目的：观察低分子肝素联合间歇充气加压对髋膝关节术后静脉血栓的预防效果。方法：从笔者所在医院收治的髋膝关节周围骨折及行人工关节置换术的患者中抽取90例随机分成两组,观察组患者在入院后使用腹壁皮下注射低分子肝素同时对双下肢交替进行间歇性充气加压来预防下肢关节的静脉血栓,对照组患者只在术后使用低分子肝素。对两组患者的静脉血栓症状进行评估,观察下肢深静脉彩超,记录围手术期的出血量。结果：观察组经过两种预防方法联合介入,其术后术侧下肢静脉血栓的发生率明显低于对照组;围手术期的出血量明显少于对照组,差异有统计学意义（P〈0.05）。结论：对髋膝关节手术使用低分子肝素联合间歇充气加压可以有效的预防术后静脉血栓,在预防髋膝关节术后静脉血栓中具有重要的应用价值。

The Preventive Effect of Low Molecular Weight Heparin Combined with Intermittent Pneumatic Compression in The Venous Thrombosis of Hip and Knee

Objective： To investigate the preventive efficacy on venous thromboembolism in patients undergoing hip or knee operation using low molecular heparin in combination with intermittent pneumatic compression. Method： 90 cases with hip or knee joint peripheral fractures and artificial joint replacements who were admitted to our hospital were randomly divided into 2 groups, the cases in observation group were treated with low molecular heparin by subcutaneous injection and intermittent pneumatic compression to both lower limbs alternately after admission, cases in control group were only treated with low molecular heparin after operation, aU patients were evaluated the clinical symptom of venous thromboembolism, examined by colour duplex ultrasonography of both lower limbs deep venous, recorded the volume of blood loss in perioperation. Result： The incidence rates of venous thromboembolism in lower limbs after operation in observation group were significantly lower than those in control group, the amourot of bleeding in obserration group is lower than the control group, and the differences both had statistical significance （ P〈0.05 ） .Conclusion ： Combined with low molecular heparin and intermittent pneumatic compression are effective to prevent the venous thromboembolism after hip or knee operation and which have preventive application value in perioperation of lower limb joints.
