Thirty-six patients scheduled for knee arthroplasty were randomized to general or epidural anesthesia that was prolonged into the postoperative period. All the patients wore graded compression stockings until full ambulation. No other thrombo-prophylactic treatment was given. In diagnosing deep venous thrombosis, bilateral ascending venography was performed 9-11 days after surgery. The incidence of thrombosis was 2/13 in the epidural group versus 10/16 in the general anesthesia group (P less than 0.05).
36例计划进行膝关节置换术的患者被随机分为全身麻醉组或硬膜外麻醉组，且术后继续延长麻醉时间。所有患者均穿着分级压力弹力袜直至完全行走。未给予其他血栓预防治疗。在诊断深静脉血栓形成时，术后9 - 11天进行双侧上行静脉造影。硬膜外组血栓形成发生率为2/13，而全身麻醉组为10/16（P小于0.05）。
