The optimal dose and protocol of tranexamic acid (TXA) for reducing blood loss in total hip arthroplasty (THA) is controversial. Intravenous TXA (IV-TXA) and combined IV-TXA with topical TXA are the two common protocol after THA. A meta-analysis of randomized controlled trials (RCTs) to compare the efficacy and safety of combined IV and topical TXA with IV-TXA alone in reducing blood loss after THA.
PubMed, Medline, Embase, Web of Science, the Cochrane Library, China Wanfang database and Google database were searched from the inception to February 2017 to identify RCTs that comparing combined IV and topical TXA with IV-TXA alone for patients prepared for primary THA. Total blood loss, hidden blood loss, transfusion rate, hemoglobin drop, length of hospital stay and the occurrence of deep venous thrombosis (DVT) were pooled to comprehensive analyses the efficacy and safety of combined IV and topical TXA with IV-TXA alone. Software Stata 12.0 was used to calculated relevant data.
Six RCTs involving 747 patients were finally included in the meta-analysis. Combined TXA decrease the volume of total blood loss and hidden blood loss by 250.37 ml (MD = -250.37; 95% CI: -376.43 to -124.31, P = 0.000) and 117.23 ml respectively (MD = -117.23; 95% CI: 228.38 to -6.07, P = 0.091). Meanwhile, combined TXA can also decrease the transfusion rate by 9.1% (RR = 0.32; 95% CI: 0.17 to 0.63; P = 0.001). No significant differences were seen in hemoglobin drop, the length of hospital stay and the occurrence of DVT between the two groups (P > 0.05).
Our meta-analysis suggests that the combined application of IV and topical TXA for patients undergoing THA may reduce the total blood loss compared with IV use alone without increasing the risk of postoperative complications. However, due to the quality and number of included studies, more studies were need to further identify the optimal dose for combine IV-TXA.
氨甲环酸(TXA)在全髋关节置换术(THA)中减少失血的最佳剂量和方案仍存在争议。静脉注射 TXA(IV-TXA)和 IV-TXA 联合局部 TXA 是 THA 后的两种常见方案。本研究旨在通过荟萃分析比较 IV-TXA 与 IV-TXA 联合局部 TXA 用于初次 THA 的疗效和安全性。
从建库至 2017 年 2 月,检索 PubMed、Medline、Embase、Web of Science、Cochrane 图书馆、中国万方数据库和 Google 数据库,以识别比较 IV-TXA 与 IV-TXA 联合局部 TXA 用于初次 THA 的随机对照试验(RCT)。汇总分析总失血量、隐性失血量、输血率、血红蛋白下降、住院时间和深静脉血栓形成(DVT)发生率,以综合分析 IV-TXA 联合局部 TXA 与 IV-TXA 单独应用的疗效和安全性。采用 Stata 12.0 软件计算相关数据。
最终纳入 6 项 RCT,共 747 例患者。与 IV-TXA 相比,联合 TXA 可分别减少总失血量和隐性失血量 250.37ml(MD=-250.37;95%CI:-376.43 至-124.31,P=0.000)和 117.23ml(MD=-117.23;95%CI:228.38 至-6.07,P=0.091)。同时,联合 TXA 还可降低输血率 9.1%(RR=0.32;95%CI:0.17 至 0.63;P=0.001)。两组血红蛋白下降、住院时间和 DVT 发生率差异无统计学意义(P>0.05)。
本荟萃分析表明,与单独使用 IV 相比,THA 患者联合应用 IV 和局部 TXA 可能会减少总失血量,而不会增加术后并发症的风险。但是,由于纳入研究的质量和数量,需要更多的研究来进一步确定联合 IV-TXA 的最佳剂量。
