Abstract:

BACKGROUND: Deep venous thrombosis and blood loss are common complications after total hip arthroplasty in elderly patients. Thus, it needs to pick valid treatments to reduce the harm in the clinical treatment.

OBJECTIVE: To compare and observe the effects of rivaroxaban and low molecular heparin on preventing deep venous thrombosis and blood loss after total hip arthroplasty in elderly patients. 
METHODS: 196 cases in Department of Orthopedics, General Hospital of Shuicheng Mining Group of Guizhou Province treated by unilateral total hip arthroplasty were enrolled between January 2015 and January 2017. They were randomly divided into observation group (98 cases) and control group (98 cases). The observation group was treated with oral rivaroxaban 6 hours after surgery for 2 consecutive weeks. The control group was subcutaneously injected with low molecular heparin injection 6 hours after surgery for 5 consecutive weeks. The coagulation index was measured by automatic coagulation analyzer at preoperative, 1 day, 1 and 2 weeks after surgery. Deep venous thrombosis was evaluated in the two groups. The caliber sizes of superficial femoral vein and popliteal vein were measured by color Doppler ultrasound before surgery, 1, 2, 3 and 4 weeks after surgery. Blood loss was recorded in the two groups.
RESULTS AND CONCLUSION: (1) The difference in serum D-dimer levels was statistically significant 1 and 2 weeks after surgery in both groups (P < 0.05). Serum D-dimer levels were lower in the observation group than in the control group. (2) The incidence of deep venous thrombosis was lower in the observation group than in the control group (P < 0.05). (3) The caliber size of superficial femoral vein and popliteal vein was significantly different 1, 2, 3 and 4 weeks after surgery in both groups (P < 0.05). The caliber size of superficial femoral vein and popliteal vein was larger in the observation group than in the control group. (4) Hidden blood loss and total blood loss were significantly different between the two groups (P < 0.05). The hidden blood loss and total blood loss were higher in the observation group than in the control group. (5) Results suggest that rivaroxaban has a positive meaning for prevention of deep venous thrombosis after total hip arthroplasty in elderly patients. However, hidden blood loss is worthy of attention.
