A systematic review and meta-analysis comparing combined intravenous and topical tranexamic acid with intravenous administration alone in THA.

ABSTRACT: To compare the effectiveness and safety of combined intravenous and topical tranexamic acid with intravenous use alone in THA.The electronic databases MEDLINE, EMBASE, BIOSIS, Cochrane central, and further adapted for Google and Google Scholar internet, last updated on Dec 30, 2016, were searched. Evaluated outcomes included total blood loss, transfusion rate, maximum postoperative Hb drop, and incidence of thromboembolic complications. The standard mean difference (SMD) or the relative risk (RR) was calculated for continuous or dichotomous data respectively. The quality of the trial was assessed, and meta-analyses were performed with the Cochrane Collaboration's RevMan 5.0 software.Five RCTs with 457 patients were included. Combined TXA administration reduced blood loss (SMD, 1.39; 95%CI, 0.55 to 2.23; P<0.00001, I2 = 94%), hemoglobin decline (SMD, 0.84; 95%CI, 0.13 to 1.54; P = 0.01, I2 = 83%) and the need for transfusion (RR, 2.58; 95%CI, 1.59 to 4.18; P = 0.65, I2 = 0%) without increasing the rate of thromboembolic complications significantly (RR, 0.83; 95%CI, 0.27 to 2.54; P = 0.81, I2 = 0%).The present study has emphasized that combined TXA administration can effectively reduce blood loss, hemoglobin decline and the need for transfusion without increasing the rate of thromboembolic complications.

Project description:OBJECTIVE:This study aimed to compare the effects of intravenous, topical and combined routes of tranexamic acid (TXA) administration on blood loss and transfusion requirements in patients undergoing total knee arthroplasty (TKA) and total hip arthroplasty (THA). DESIGN:This was a meta-analysis of randomised controlled trials (RCT) wherein the weighted mean difference (WMD) and relative risk (RR) were used for data synthesis applied in the random effects model. Stratified analyses based on the surgery type, region, intravenous and topical TXA dose and transfusion protocol were also conducted. The main outcomes included intraoperative and total blood loss volume, transfusion rate, low postoperative haemoglobin (Hb) level and postoperative Hb decline. However, the secondary outcomes included length of hospital stay (LOS) and/or occurrence of venous thromboembolism (VTE). SETTING:We searched the PubMed, Embase and Cochrane CENTRAL databases for RCTs that compared different routes of TXA administration. PARTICIPANTS:Patients undergoing TKA or THA. INTERVENTIONS:Intravenous, topical or combined intravenous and topical TXA. RESULTS:Twenty-six RCTs were selected, and the intravenous route did not differ substantially from the topical route with respect to the total blood loss volume (WMD=30.92, p=0.31), drain blood loss (WMD=-34.53, p=0.50), postoperative Hb levels (WMD=-0.01, p=0.96), Hb decline (WMD=-0.39, p=0.08), LOS (WMD=0.15, p=0.38), transfusion rate (RR=1.08, p=0.75) and VTE occurrence (RR=1.89, p=0.15). Compared with the combined-delivery group, the single-route group had significantly increased total blood loss volume (WMD=198.07, p<0.05), greater Hb decline (WMD=0.56, p<0.05) and higher transfusion rates (RR=2.51, p<0.05). However, no significant difference was noted in the drain blood loss, postoperative Hb levels and VTE events between the two groups. The intravenous and topical routes had comparable efficacy and safety profiles. CONCLUSIONS:The combination of intravenous and topical TXA was relatively more effective in controlling bleeding without increased risk of VTE.
