To determine whether a small fixed perioperative dose of warfarin would prevent deep vein thrombosis after total hip replacement.
Prospective, randomised, double blind placebo controlled trial.
Winford Orthopaedic Hospital, Bristol.
148 patients having primary total hip replacement.
Warfarin 1 mg given daily for one week before and three weeks after surgery.
Deep vein thrombosis diagnosed by the iodine-125 labelled fibrinogen uptake method.
Deep vein thrombosis occurred in 25 (34%) of the patients given warfarin and 19 (26%) of the controls (difference 8%; 95% confidence interval -6.8% to 22.8%).
Fixed minidose warfarin does not prevent deep vein thrombosis after total hip replacement.
确定围手术期小剂量固定剂量的华法林是否能预防全髋关节置换术后深静脉血栓形成。
前瞻性、随机、双盲、安慰剂对照试验。
布里斯托尔温福德骨科医院。
148例行初次全髋关节置换术的患者。
术前1周及术后3周每天给予1毫克华法林。
采用碘-125标记纤维蛋白原摄取法诊断深静脉血栓形成。
服用华法林的患者中有25例(34%)发生深静脉血栓形成,对照组中有19例(26%)发生(差异8%;95%置信区间为-6.8%至22.8%)。
固定小剂量华法林不能预防全髋关节置换术后深静脉血栓形成。
