Abstract:
Objective To analyse the clinical effect and mechanism of hirudin in the treatment of patients with lower limb venous thrombosis after fracture.Methods 56 patients who were diagnosed with lower limb venous thrombosis after fracture in our hospital were collected.All patients were randomly divided into experimental group (n:28) and control group (n:28).12h after fracture operation, patients in control group were treated with subcutaneous injection of low molecular weight heparin calcium, patients in experimental group were treated with Maixuekang capsule ( hirudin) orally on the basis of control group.Before and after the treatment, the plasma levels of thrombin antithrombin complex ( TAT) , thrombin activated fiber soluble inhibitor (TAFI), D-Dimer (D-D), fibrinogen (FIB), thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT) and clinical effect were detected in all patients.Results After treatment, the total effective rate of experimental group ( 92.86%) was significantly higher than that of the control group ( 71.43%) ( P<0.05 );compared with control group, the plasma levels of TAT, TAFI were lower in the experimental group (P<0.05); the plasma levels of D-D, FIB were lower in the experimental group (P<0.05); the plasma levels of TT,PT,APTT were higher in the experimental group ( P<0.05 ) .Conclusion The hirudin could inhibit thrombin activation and coagulation function in fracture patients with lower limb venous thrombosis, decrease the plasma D-D and FIB levels for improving blood hypercoagulable state and preventing thrombosis,thus improve the clinical efficacy.
