周期性充气加压预防下肢手术后深静脉血栓

目的 探讨单独使用周期性充气加压（ＩＰＣ）预防下肢手术后深静脉血栓（ＤＶＴ）的效果。方法１９９７年１０月￣１９９８年８地４０例下肢手术患者使用ＩＰＣ预防ＤＶＴ。其中人工全髋关节置换术２４例，髋滑动加压鹅头钉术１２例，人工全膝关节表面置换术４例。术前超声多普勒证实双下肢无ＤＶＴ，术后开始使用ＩＰＣ，术后当天持续使用ＩＰＣ８小时，术后第１天起每隔６小时使用ＩＰＣ一次，每次２小时，直至出院，整个疗程至少

PREVENTION OF POSTOPERATIVE DEEP VENOUS THROMBOSIS IN LOWER LIMB AFTER OPERATION BY INTERMITTENT PNEUMATIC COMPRESSION

Objective To investigate the effect of intermittent pneumatic compression on prevention of deep venous thrombosis after operation of lower limbs. Methods From Oct. 1997 to Aug. 1998, forty cases were received Doppler examination preoperatively, which showed no deep venous thrombosis in all the lower limbs of 40 cases. Among them, 24 cases were received total hip arthroplastics, 4 cases were received total knee arthroplastics and 12 cases were received dynamic hip screw. Postoperatively, every case were continuously received intermittent pneumatic compression for 14 to 21 days(2 hours, qid), and venography were performed on the operated lower limb on the 7th day after operation to check the presence of deep venous thrombosis.Results Among the 40 cases, there were 4 cases of deep venous thrombosis without symptom of pulmonary embolism, the incidence rate was 10%. Conclusion Intermittent pneumatic compression can significantly reduce the incidence rate of deep venous thrombosis after the operation of the lower limbs.
