AIM: The aim of this meta-analysis was to assess the safety and efficacy of tranexamic acid (TXA) in the management of hip fracture surgeries in comparison with placebo. METHODS: A systematic search was conducted from August 6, 2021. Eligible studies included randomized clinical trials and prospective studies comparing the use of intravenous TXA in patients treated for hip fractures, in comparison with placebo. Review Manager was used for the meta-analysis. RESULTS: Eighteen prospective studies including 14 RCTs met the eligibility criteria. The results favored the TXA group in the quantity of total blood loss (MD = - 196.91 mL, 95% CI - 247.59, - 146.23, I = 92%), intraoperative blood loss (MD = - 26.86 mL, 95% CI - 36.96, - 16.78, I = 62%), and rate of blood transfusion (OR 0.35, 95% CI 0.28, 0.42, I = 0%). TXA also exhibited higher hemoglobin level at day 1 (MD = 6.77 g/L, 95% CI 4.30, 9.24, I = 83%) and day 3 (MD = 7.02 g/L, 95% CI 3.30, 10.74, I = 82%) postoperatively. There was no significant difference found in the incidence of thromboembolic events from occurring between the two groups, such as deep vein thrombosis (OR 1.22, 95% CI 0.73, 2.02, I = 0%) and pulmonary embolism (OR 0.82, 95% CI 0.33, 2.05, I = 0%). CONCLUSION: Administration of intravenous TXA appears to reduce blood loss, rate of blood transfusions and pose no increased risk of thromboembolic events. Therefore, TXA should be considered by physicians when managing hip fracture patients.
目的:本荟萃分析旨在评估氨甲环酸(TXA)在髋部骨折手术管理中的安全性和疗效,并与安慰剂进行比较。
方法:系统检索 2021 年 8 月 6 日至 2021 年 8 月 6 日期间的相关研究。纳入比较静脉注射 TXA 与安慰剂治疗髋部骨折患者的随机临床试验和前瞻性研究。采用 Review Manager 进行荟萃分析。
结果:纳入了 18 项前瞻性研究,其中包括 14 项 RCT。结果显示,TXA 组的总失血量(MD = -196.91 mL,95% CI -247.59,-146.23,I²=92%)、术中失血量(MD = -26.86 mL,95% CI -36.96,-16.78,I²=62%)和输血率(OR 0.35,95% CI 0.28,0.42,I²=0%)均更优。TXA 组在术后第 1 天(MD = 6.77 g/L,95% CI 4.30,9.24,I²=83%)和第 3 天(MD = 7.02 g/L,95% CI 3.30,10.74,I²=82%)的血红蛋白水平也更高。两组深静脉血栓形成(OR 1.22,95% CI 0.73,2.02,I²=0%)和肺栓塞(OR 0.82,95% CI 0.33,2.05,I²=0%)等血栓栓塞事件的发生率无显著差异。
结论:静脉注射 TXA 可减少失血、输血率,且不会增加血栓栓塞事件的风险。因此,在管理髋部骨折患者时,医生应考虑使用 TXA。
