A retrospective study of 521 Charnley hip replacements involving 471 patients is presented, assessing the effect of mechanical prophylaxis against deep vein thrombosis. During the operation venous flow was stimulated in all cases by passive movement at the ankle joint. In addition, all patients used Flowtron leggings--a non-invasive, intermittent pneumatic compression device - on the unoperated leg during the operation and on both legs during the first 24 hours after the operation. The patients were mobilized as soon as possible with weight-bearing on the operated leg from the second postoperative day. As indicated by the results, the above combination of early mobilization, peroperative stimulation of the venous flow and the use of Flowtron leggings lowered the incidence of thromboembolic complications to 3.6 per cent.
本文呈现了一项针对471例患者的521例Charnley髋关节置换术的回顾性研究，评估了机械性预防深静脉血栓形成的效果。手术过程中，所有病例均通过踝关节被动运动来刺激静脉血流。此外，所有患者在手术期间对未手术侧腿使用Flowtron弹力袜——一种非侵入性间歇性气动压迫装置，术后24小时内双侧腿均使用。从术后第二天起，患者尽快进行活动，手术侧腿负重。结果表明，早期活动、术中静脉血流刺激以及使用Flowtron弹力袜的上述组合将血栓栓塞并发症的发生率降至3.6%。
