![]() These clots can eventually break off and make their way to the lungs. The goal of the device is to prevent the possibility of the formation of blood clots in the lower part of the leg. Sequential compression devices do not affect tissue plasminogen activator or plasminogen activator inhibitor-1 levels, suggesting no fibrinolytic benefit. A sequential compression device, or SCD, which also goes by the name lymphedema pump, is used by patients to place intermittent compression on their legs. No significant change in systemic fibrinolytic activity occurs during outpatient plastic surgery under total intravenous anesthesia. There were no significant changes in tissue plasminogen activator levels or plasminogen activator inhibitor-1 levels from the preoperative measurements at any hourly interval and no differences in levels comparing patients treated with or without sequential compression devices. No patient developed clinical signs or ultrasound evidence of a deep venous thrombosis. There was no outside funding for the study.Īll patients agreed to participate (inclusion rate, 100 percent). Ultrasound surveillance was used in all patients. Tissue plasminogen activator and plasminogen activator inhibitor-1 levels were measured. Blood samples were obtained from the upper extremity preoperatively and at hourly intervals until the patient was discharged from the postanesthesia care unit. Request PDF Pulmonary Embolism as a Consequence of Applying Sequential Compression Device on Legs in a Patient Asymptomatic of Deep Vein Thrombosis. Patients were randomized to receive calf-length sequential compression devices or no sequential compression devices during surgery. Rapid inflation, high pressures, and graded sequential intermittent compression systems. Compression stockings appear to function more by preventing distension of veins. The plasma levels of tissue plasminogen activator and plasminogen activator inhibitor-1 reflect fibrinolytic activity.Ī randomized trial was conducted among 50 consecutive plastic surgery outpatients undergoing cosmetic surgery performed by the author under total intravenous anesthesia and without paralysis. Results: All the major types of intermittent compression systems are successful in emptying deep veins of the lower limb and preventing stasis in a variety of subject groups. A systemic fibrinolytic effect has also been proposed, adding a second mechanism of action. The devices are believed to produce a milking action on the deep veins to prevent venous stasis. Sequential compression devices are often considered a mainstay of prophylaxis against deep venous thromboses in surgical patients.
