周期性充气加压预防髋关节置换术后下肢深静脉血栓的效果

目的比较观察单纯使用周期性充气加压系统（IPCS）与低分子肝素预防人工全髋关节置换术后下肢深静脉血栓（DVT）的临床效果。方法选取61例单侧初次全髋关节置换术的患者，随机分成IPCS组和低分子肝素组。低分子肝素组从术前第1天开始应用低分子肝素0．2ml/d，皮下注射。IPCS组术后立即使用IPCS治疗，每天5h，术后14d内持续使用。每个研究对象分别于术前1d、术后第3、7d各进行下肢深静脉超声、血浆D-二聚体、P-选择素测定。结果肝素组和IPCS组发生DVT分别为2例和3例；两组均未出现有临床症状的肺栓塞；两组临床效果差异无显著性（P〉0．05）。结论下肢IPCS系统对全髋关节置换术后的DVT形成具有很好的预防作用，是一种安全、简便的物理疗法。

Comparison of intermittent pneumatic compression system with low-molecular-weight heparin for the prevention of deep-vein thrombosis after total hip replacement

Objective To compare the safety and effectiveness of the intermittent pneumatic compression system with those of low-molecular-weight heparin for prevention of deep-vein thrombosis after total hip replacement.Methods 61 patients were performed a randomized trial to evaluate the effectiveness and safety of low-molecular-weight heparin as compared with the intermittent pneumatic compression system to prevent deep-venous thrombosis after total hip replacement.Patients in low-molecular-weight heparin group were...
