Effects and Safety Observation of Different Treatment Courses of Rivaroxiban in Prevention and Treat-ment of Deep Venous Thrombosis after Total Hip Replacement / 中国药房

ABSTRACT

OBJECTIVE:To observe the effects and safety of different treatment courses of rivaroxaban in prevention and treatment of deep venous thrombosis(DVT)after total hip replacement. METHODS:The clinical data of 127 patients under-went selective total hip replacement in our hospital during Dec. 2014-Dec. 2015 were selected and analyzed retrospectively. They were divided into group A [83 cases,subdivided into group A1(40 cases)and A2(43 cases)by treatment course] and group B (44 cases) according to anticoagulant duration. Group A was given Rivaroxaban tablet 10 mg,po,qd,6-8 h after surgery;the treatment course of group A1 was 5 weeks(35 d)while that of group A2 was 2 weeks(14 d). Group B was giv-en Enoxaparin sodium injection 5000 AxaIU,sc,qd,12d before surgery;and then given Enoxaparin sodium injection 5000 AxaIU,sc,qd,after surgery;the treatment course lasted for 2 weeks. The incidence of DVT were compared among 3 groups as well as thrombin time(TT),activated partial thromboplastin time(APTT),hemoglobin(Hb)content,whole blood viscos-ity,plasma viscosity,platelet count and anticoagulant safety 3 days before surgery and after treatment. RESULTS:The inci-dence of DVT in group A1 was 0,which was significantly lower than that in group A2 (9.30%) and group B (11.36%), with statistical significance(P0.05). Wheth-er 3 d before surgery or after treatment,there was no statistical significance in PT,APTT,Hb content,whole blood viscosi-ty,plasma viscosity and platelet count among 3 groups (P>0.05). No major bleeding events or pulmonary embolism was found in 3 groups. The incidence of mild bleeding events in group A was 5.00%,which was slightly higher than that in group A2 (2.33%) and group B (2.27%),without statistical significance (P>0.05);there was no statistical significance between group A2 and group B(P>0.05). CONCLUSIONS:Rivaroxiban long-term anticoagulation after total hip replacement has no significant effect on coagulation function and platelet,not only decrease the incidence of DVT,but also will not increase no bleeding with good safety.
