Influences of Antithrombotic Elastic Socks Combined with Air Pressure in Reducing Lower Extremity Deep Venous Thrombosis for Patients Undergoing Cardiothoracic Surgery

Abstract

This study was designed to investigate the application and therapeutic effect of antithrombotic elastic socks combined with air pressure in the prevention of lower extremity deep venous thrombosis in patients undergoing cardiothoracic surgery. Sixty patients in cardiothoracic surgery of our hospital from January 2019 to December 2020 were randomly divided into a study group and control group. The control group was treated with routine treatment intervention. Based on routine treatment intervention, the study group was treated with antithrombotic elastic socks combined with pneumatic treatment intervention. The activated partial thromboplastin time (APTT), thrombin time (TT), femoral venous blood flow velocity of both lower limbs, and the incidence of lower extremity deep venous thrombosis (LEDVT), postoperative lower extremity swelling, inflammatory factors, and satisfaction were measured. After intervention, APTT ( $31.74\pm 1.15$  s) and TT ( $14.58\pm 0.24$  s) in the study group were higher than those in the control group APTT ( $25.13\pm 1.14$  s) and TT ( $12.14\pm 0.23$  s) ( $P<0.05$ ). The left lower limb femoral vein blood flow velocity and the right lower limb femoral vein blood flow velocity in the study group were better than those in the control group ( $P<0.05$ ). The incidence of postoperative lower limb swelling and deep vein in the study group was lower than that in the control group ( $P<0.05$ ). Serum tumor necrosis factor alpha and interleukin-6 concentrations in the study group were lower than those in the control group ( $P<0.05$ ). The satisfaction rate of patients in the study group (93.33%) was significantly higher than that in the control group (70.00%) ( $P<0.05$ ). In conclusion, after cardiothoracic surgery, antithrombotic elastic socks combined with air pressure can significantly reduce the incidence of LEDVT by improving patients’ coagulation function, reducing inflammatory reaction. It is worthy of popularization and application in relevant surgery.
