Aim and Objective: To evaluate the efficacy and safety of Chinese herbal medicines for promoting blood circulation and removing blood stasis (PBCRBSM) in preventing deep venous thrombosis (DVT) after total hip arthroplasty
Materials and Methods: The Databases were searched for studies comparing the preventive abilities of PBCRBSM and
Western medicine, such as low molecular weight heparin (LMWH), rivaroxaban, and aspirin, as well as for randomized controlled trials on DVT after THA. Data were analyzed using RevMan 5.3 software.
Results: A total of 3254 randomized controlled trials were included, including 1630 cases in the experimental group and
1624 cases in the control group. Meta-analysis showed that compared with Western medicine, PBCRBSM reduced the incidence of DVT (OR=0.38, 95% CI [0.30, 0.48], P < 0.001); prolonged activated partial thromboplastin time (APTT)
(SMD=0.44, 95% CI [0.35, 0.53], P < 0.001); reduced D-dimer (SMD=-0.75, 95% CI [-0.84，-0.65], P < 0.001), FIB
(SMD=-0.61, 95% CI [-0.72, -0.50], P < 0.001), blood viscosity (P<0.01), circumference difference in lower extremities
(P<0.01), venous blood flow velocity (SMD=0.97, 95% CI [0.77, 1.16], P < 0.001), and drainage volume (SMD=-1.53, 95%
CI [-1.71, -1.35], P < 0.001); and reduced adverse reactions (OR = 0.32, 95% CI [0.19, 0.56], P < 0.001). There was no significant difference in prolonging prothrombin time (PT) between traditional Chinese medicine and Western medicine (SMD
= 0.07, 95% CI [-0.0.01). 3, 0.16], P > 0.05.
Conclusion: PBCRBSM is an effective method for preventing DVT after THA and has fewer adverse effects.
