Graded pressure stockings significantly reduced the incidence of venographically determined deep venous thrombosis (DVT) after total hip arthroplasty. Seventy-six patients were studied; the incidence of DVT was 54 per cent in 41 control patients and 20 per cent in 35 patients who wore stockings. Administration of blood during the operation and in the first 24 h after operation, if given in excess of blood loss, was associated with a significantly increased risk of developing DVT. The application of graded pressure stockings and the avoidance of unnecessary perioperative blood transfusion are worth while in the management of total hip arthroplasty.
分级压力弹力袜显著降低了全髋关节置换术后经静脉造影确定的深静脉血栓形成（DVT）的发生率。对76例患者进行了研究；41例对照患者中DVT的发生率为54%，而35例穿着弹力袜的患者中该发生率为20%。手术期间及术后24小时内，如果输血超过失血量，发生DVT的风险会显著增加。在全髋关节置换术的管理中，应用分级压力弹力袜并避免不必要的围手术期输血是值得的。
