低分子肝素对老年卧床患者下肢深静脉血栓的预防

Prevention of Low Molecular Weight Heparin on Deep Vein Thrombosis of Elderly Bedridden Patients and the Security

目的:探讨低分子肝素对老年卧床患者下肢深静脉血栓(Deep Vein Thrombosis,DVT)发生预防的有效性和安全性。方法:选取65岁以上、卧床时间大于3天的住院患者患者76例随机分为2组:对照组行物理方法预防;试验组行物理方法+低分子肝素预防。分别于入院14天查血常规、凝血全项,下肢静脉彩超。结果:对照组3例发生DVT,发生率g%,实验组1例发生DVT,发生率3%,两组比较有统计学差异(P<0.05)。结论:应用低分子肝素能有效地预防内科老年卧床住院患者深静脉血栓的发生。

Objective：we observed the effect of low molecular weight heparin on deep vein thrombosis of elderly bedridden patients and the security.Methods：Create hospitalized patients（age〉75 old）76 cases who is greater than 3 days in bed were used in this study, After operation, patients were randomly divided to 2 groups： model group （treat with physical methods ）,enhanced group （treat with physical methods and low molecular weight heparin ）. Model and Enhanced were test routine blood, items of coagulation, lower extremity venous color Doppler ultrasound lasted for 14d in hospital. Results： Deep vein thrombosis of model group occur be 3 cases ,the ineidence of 11%, and enhanced group occur be 1 case, the incidence of 3%. Comparing the two groups was statistically different（P〈0.05）. Conclusion： Low molecular weight heparin could effentive in preventing deep vein thrombosis of elderly bedridden patients.
