Efficacy and safety of the injection of the traditional Chinese medicine salviae miltiorrhizae and ligustrazine hydrochloride for the treatment of perioperative period of fracture

The injection of the traditional Chinese patent medicine salviae miltiorrhizae and ligustrazine hydrochloride injection (SMLHI) has been widely used in treatment of various diseases such as angina pectoris or ischemic stroke in China. We aim to evaluate the efficacy and safety of SMLHI for the treatment of perioperative period of fracture.A systematic literature search was performed in seven medical databases from their inception until February 2019. 16 studies with randomized controlled trials, totaling 1589 patients, were included in this meta-analysis. The included studies were assessed by the cochrane risk of bias and analyzed by Review Manager 5.3 software.The meta-analysis showed that SMLHI for the treatment of perioperative period of fracture was significantly better compared with the control group in terms of the total effective rate. The result showed that SMLHI could significantly reduce the risk of deep vein thrombosis and inflammatory cytokines. Furthermore, the result showed that SMLHI could significantly improve the coagulation function indexes such as prothrombin time, plasma fibrinogen and D-Dimer (P < .0001).This meta-analysis demonstrated that SMLHI may be more effective and safe for the treatment of perioperative period of fracture. However, further and higher quality randomized controlled trials are required to prove treatment outcome.
