PURPOSE: We conducted this meta-analysis of randomized controlled trials (RCTs) to compare the efficacy of different doses of intravenous tranexamic acid (TXA) in spinal surgery. METHODS: We searched relevant academic articles from PubMed, Embase, the Cochrane Library, and CNKI. Two reviewers independently selected studies, assessed quality, extracted data, and evaluated the risk of bias. RevMan 5.4 was used for data analysis. RESULTS: Ten randomized controlled trials (RCTs) met the inclusion criteria and were identified, including 740 patients. According to the different dose regimens of intravenous TXA, the included studies' patients were divided into the high dose of intravenous TXA group and the low dose of intravenous TXA group. Compared with the low-dose group, the high-dose group can reduce the intraoperative blood loss (MD = - 100.87, 95% CI: [- 147.81, - 53.92], P < 0.0001). For the postoperative Hb and HCT, the high-dose group can separately maintain 4.54 g/dL (MD = 4.54, 95% CI: [2.08, 6.99], P = 0.003) and 1.27% (MD = 1.27, 95% CI: [0.59, 1.94], P = 0.0002). There were no statistically significant differences in total blood loss, preoperative Hb and HCT, operative time, and blood transfusion rate between the high-dose group and the low-dose group. CONCLUSIONS: Based on the present meta-analysis, compared with the low-dose of intravenous TXA in spinal surgery, the high dose of intravenous TXA decreases the intraoperative blood loss and preserves higher postoperative Hb and HCT levels without increasing the operative time and blood transfusion rate.
