9/6/2023 0 Comments Sequential compressionThese devices help blood move more efficiently through the veins. When the sleeve deflates, blood flows back to the legs. This squeezing motion forces blood through the veins all the way to the heart. At certain intervals, air pumps through connector tubes and inflates the sleeves, squeezing your legs similar to the way a blood pressure cuff works on your upper arm. Leg compression machines-called intermittent pneumatic compression (IPC) machines in the medical community-are sleeves or cuffs with air chambers that are worn around the legs and, occasionally, the feet.

Sequential compression devices do not affect tissue plasminogen activator or plasminogen activator inhibitor-1 levels, suggesting no fibrinolytic benefit.The Forbes Health editorial team is independent and objective. 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. Patients were randomized to receive calf-length sequential compression devices or no sequential compression devices during surgery. 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. 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.
