The Effect Of Intermittent Pneumatic Compression In Orthopedic Surgery For Lower Limbs To Prevent Deep Venous Thrombosis

Objective:To investigate the effect of intermittent pneumatic compression(IPC)in dynamics of blood flow,blood coagulation function,operation time,intraoperative blood loss and the prevention of deep vein thrombosis(DVT)in these patients undergoing orthopedic surgery for lower limbs.To seek effective measures to prevent DVT in orthopedic surgery for unilateral lower limbs,decrease the incidence of DVT and provide a basis for the prevention of DVT in surgery.Methods:120 cases of patients undergoing orthopedic surgery for unilateral lower limbs were randomly divided into control group and intervention group,and each group had 60 cases.Patients of control group were given conventional nursing.Based on conventional nursing,patients of intervention group were given IPC during surgery to compare the incidence of DVT,venous diameter,venous velocity,coagulation index,operative time and intraoperative blood loss between the two groups.Results:1.The incidence of DVT was 8.33% in the control group and 3.33% in the intervention group.Although the incidence of DVT in the intervention group was lower than that in the control group,the difference was not statistically significant(P > 0.05).2.There was no statistically significant difference in diameter of external iliac vein,common femoral vein,deep femoral vein and popliteal vein between the two groups after surgery(P > 0.05).There was statistically significant difference in flow velocity of external iliac vein,common femoral vein,deep femoral vein and popliteal vein between the two groups after surgery(P < 0.05).3.There was statistically significant difference in fibrinogen and D-dimer between the two groups after surgery(P < 0.05).There was no statistically significant difference in prothrombin time,activated partial thromboplastin time,thrombin time and platelet count between the two groups after surgery(P > 0.05).4.There was no statistically significant difference in the operative time and intraoperative blood loss between the two groups(P > 0.05).Conclusion:1.Intraoperative application of IPC in the non-operative side doesn't significantly decrease the incidence of DVT after orthopedic surgery for unilateral lower limbs.2.Intraoperative application of IPC can effectively promote blood reflux in lower limbs,relieve intraoperative blood stasis and activate the fibrinolysis system and promote fibrinolysis,while it doesn't increase the risk of intraoperative bleeding.It is safe and convenient to applicate IPC in surgery.
