目的 探讨低分子肝素对于普外科手术后静脉血栓形成的预防效果。方法 选取2012年1月~2013年6月叶县人民医院普外科收治的手术患者90例,随机均分为2组（n=45）。观察组术后低分子肝素治疗,对照组不采取此治疗手段,观察2组患者体征及B超检查结果的差异。结果 观察组45例患者中33例术后大出血患者在使用低分子肝素后有明显的缓解作用,所有患者在术后15d后均未出现血栓症状。明显好于对照组的治疗效果。结论 低分子肝素对于防止普通外科手术后静脉血栓的形成具有较好的预防作用。

ObjectiveTo observe the preventive action to venous thrombus of the low molecular weight heparin for the surgical operation. Methods Select 90 cases of patients who were for surgical operation in our hospital as the research object,divided them into observation group and control group.Treated the observation group with low molecular weight heparin and the conventional treatment method,but thecontrol group only with the conventional treatment method.Control the difference of signs and examination results by B ultrasound in two groups.Results There are 33 cases of postoperative bleeding with obvious relieve effect after using the low molecular weight heparin in patients of 45,all the patients showed no thrombosis symptoms after 15 days,better than the control group.Conclusion Low molecular weight heparin has a good preventive action to venous thrombus of the surgical operation.
