Physical methods became recently more important as an alternative to anticoagulation for prophylaxis of thromboembolism and were studied for their efficacy. The AV-impulse-system proved efficient in reducing thromboembolic complications in patients undergoing hip surgery by increasing the return of venous blood in the deep veins of the leg. In a preclinical trial we studied the influence of the AV-impulse-system and of active forefoot movement on venous blood return in 12 lower extremities of 6 healthy individuals immobilized in below the knee plaster casts. Our results show a significant increase in venous blood flow caused by the AV-impulse-system (p < 0.05) and by active forefoot movements (p < 0.05). Prevention of thromboembolic complications in trauma and orthopaedic patients immobilized in plaster cast seems possible by using the AV-impulse-system which significantly increases the venous blood flow independent from patient compliance.
作为预防血栓栓塞的抗凝替代方法，物理方法近来变得更为重要，并对其疗效进行了研究。AV脉冲系统通过增加腿部深静脉的静脉血回流，被证明在降低髋关节手术患者的血栓栓塞并发症方面有效。在一项临床前试验中，我们研究了AV脉冲系统和主动前足运动对6名健康个体固定于膝下石膏模型的12条下肢静脉血回流的影响。我们的结果显示，AV脉冲系统（p < 0.05）和主动前足运动（p < 0.05）均导致静脉血流显著增加。通过使用AV脉冲系统，似乎有可能预防固定于石膏模型的创伤和骨科患者的血栓栓塞并发症，该系统可显著增加静脉血流，且与患者的依从性无关。
