Comparison of Topical and Intravenous Tranexamic Acid on Blood Loss and Transfusion Rates in Total Hip Arthroplasty

The objective of this study was to determine whether topical tranexamic acid (TXA) carried similar hemostatic effect compared with intravenous TXA in total hip arthroplasty (THA). Three hundred and three THA patients were enrolled and randomized into 3 groups: no TXA group, topical and intravenous TXA group. The results showed that the topical and intravenous TXA group had reduced but similar blood transfusion rates (5.88% v. s. 5.94%, P = 0.816). No significant difference was detected in total blood loss between the two TXA groups [(963.4 ± 421.3) ml vs. (958.5 ± 422) ml P = 0.733]. We conclude that topical use of TXA was equally effective and safe compared with intravenous TXA in reducing blood loss and transfusion rate following THA without substantial complications.     

The effect of tranexamic acid on wound complications in primary total Hip Arthroplasty: A meta-analysis

BackgroundAllogeneic blood transfusion has been linked with an increase in the risk of surgical site infections (SSIs) through the mechanism of immunomodulation. However, no studies to date have investigated the direct relationship between blood conserving strategies including antifibrinolytics and wound complications after total hip arthroplasties (THA).MethodsA systematic review and meta-analysis of published randomised controlled trials (RCTs) to investigate the effect of tranexamic acid (TXA) on wound complications after THAs has been conducted.ResultsWe identified 25 clinical trials which were suitable for detailed data extraction. There were no trials which utilised TXA in revision THA. All studies reported on wound complications including a total of 1608 patients. Using TXA led to a 2% reduction in the risk of developing wound complications compared to the control group with no significant statistical heterogeneity among the study groups (Risk Difference −0.02, 95%, confidence interval CI -0.04 to −0.00, P = 0.01, Heterogeneity I² = 0%). However, there was no significant difference in clinical outcomes in terms of antibiotic treatment or surgical intervention among the study groups. TXA also reduced intraoperative, postoperative and total blood loss and led to a significant reduction in the proportion of patients requiring allogeneic blood transfusion with no significant differences in deep venous thrombosis, pulmonary embolisms, or other complications between the study groups.ConclusionTXA reduced blood loss and transfusion rates after primary THA surgery. It also reduced wound complication rates but the clinical significance of this needs further investigation through well designed and adequately powered RCTs.     

An Aprotinin Containing Fibrin Sealant Does Not Reduce Blood Loss in Total Hip Arthroplasty

Background

Fibrin sealants are topical agents used to reduce perioperative blood loss; however, their efficacy in total hip arthroplasty (THA) remains uncertain. The purpose of this study was to determine if a fibrin sealant containing aprotinin as an antifibrinolytic agent, TISSEEL (Baxter, Deerfield, IL), reduces postoperative blood loss and transfusion during THA when compared with intravenous (IV) tranexamic acid (TXA) and control groups.

Blood-Sparing Efficacy of Oral Tranexamic Acid in Primary Total Hip Arthroplasty

Background

Tranexamic acid (TXA) has been shown to be effective in reducing blood loss, hemoglobin drop, and blood transfusion in primary total hip arthroplasty. Most studies used intravenous form or topical form. This study was to assess the blood-sparing efficacy and safety of oral TXA in total hip arthroplasty.

Combined treatment of intraoperative cell-salvage and tranexamic acid for primary unilateral total hip arthroplasty: Are there added benefits?

BackgroundBlood management strategies in total hip arthroplasty (THA) are essential in reducing intraoperative blood loss, blood transfusion and associated complications. This study investigates whether using intraoperative cell-salvage (ICS) with tranexamic acid (TXA) has additional effects on blood loss and allogeneic transfusion in primary THA. Additionally, we evaluated the financial impact of using ICS on our institution.MethodsUsing an institutional database, 1171 cases of primary unilateral THA performed between May 2015 and January 2016 were identified. Subjects were separated into those who received only TXA (n = 323) and those who received TXA and ICS (n = 848). Calculated blood loss and post-operative blood transfusions were assessed using logistic regression. Drop in hematocrit was assessed using linear regression. Multivariable models adjusted for intraoperative blood transfusions, pre-operative autologous blood donation, anticoagulation medications, sex, and body mass index. Pricing data was used to calculate the costs associated with these interventions.ResultsThe likelihood of post-operative allogeneic blood transfusion was similar for the combined group relative to the TXA group (OR = 0.63; 95% CI: 0.26, 1.54), as was the likelihood of any post-operative blood transfusion (OR = 1.13; 95% CI: 0.63, 2.01). There was no correlative relationship between use of ICS and hematocrit drop when accounting for baseline hematocrit (R² = 0.118). Factoring in rental, service fees, and disposable equipment, the utilization of ICS added $146 to each case, resulting in a gross expenditure of over $123,000 during the study period.ConclusionsThe combination of ICS with TXA for primary unilateral THA did not improve blood loss or transfusion outcomes compared to TXA alone. As there was no observed clinical benefit to combined treatment, additional costs associated with routine usage of ICS may not be justifiable. Our institution would have reduced expenditures for blood loss management products by 85% during the study period if all patients had only received TXA.     

氨甲环酸减少初次非骨水泥全髋置换围术期失血有效性及安全性研究

背景：全髋关节置换术是治疗髋关节终末期疾病的有效手段,但其常伴随显著的失血且需要输血,人工合成抗纤溶药氨甲环酸在全髋关节置换术围手术期血液管理中正扮演着越来越重要的角色。目的：探讨术前静脉单剂量使用氨甲环酸减少初次单侧非骨水泥全髋关节置换术围术期失血的有效性及安全性。方法方法：回顾分析2012年9月至2013年3月行初次单侧非骨水泥全髋关节置换术前未使用氨甲环酸患者291例（对照组）和2013年4月至9月术前静脉单剂量使用15 mg/kg氨甲环酸患者220例（氨甲环酸组）的临床资料。比较两组术前及术后第1、3天血红蛋白,血细胞比容,住院时间,失血量,输血及血栓事件发生率。结果：氨甲环酸组围术期平均总失血量和输血率显著低于对照组[（973.30±355.65）ml vs（1275.20±453.75）ml,5.45%vs 20.62%,P〈0.001]。氨甲环酸组和对照组术后肌间静脉血栓发生率分别为5.00%和5.15%（P=0.937）。氨甲环酸组中1例（0.45%）发生深静脉血栓,对照组2例（0.69%）,两组比较差异无统计学意义。无1例出现肺栓塞。术后第1天、第3天氨甲环酸组的血红蛋白及血细胞比容均显著高于对照组（P〈0.001）。结论：术前静脉滴注15 mg/kg氨甲环酸可安全、有效地减少初次单侧非骨水泥全髋关节置换术围术期的失血及输血。     

Hemostatic and Anti-Inflammatory Effects of Carbazochrome Sodium Sulfonate in Patients Undergoing Total Knee Arthroplasty: A Randomized Controlled Trial

BackgroundPostoperative recovery after total knee arthroplasty (TKA) is associated with postoperative anemia, allogeneic transfusion, and stress immune responses to surgery. Carbazochrome sodium sulfonate (CSS) reduces bleeding through several mechanisms. We assessed the effect of CSS combined with tranexamic acid (TXA) on postoperative anemia, blood transfusion, and inflammatory responses.MethodsThis study was designed as a randomized, placebo-controlled trial of 200 patients undergoing unilateral primary TKA. Patients were divided into 4 groups: group A received TXA plus topical and intravenous CSS; group B received TXA plus topical CSS only; group C received TXA plus intravenous CSS only; group D received TXA only.ResultsTotal blood loss in groups A (609.92 ± 221.24 mL), B (753.16 ± 247.67 mL), and C (829.23 ± 297.45 mL) was lower than in group D (1158.26 ± 334.13 mL, P < .05). There was no difference in total blood loss between groups B and C. We also found that compared with group D, the postoperative swelling rate, biomarker level of inflammation, visual analog scale pain score, and range of motion at discharge in groups A, B, and C were significantly improved (P < .05). No thromboembolic complications occurred. There were no differences in transfusion rate, intraoperative blood loss, platelet count, or average length of stay among the 4 groups (P > .05).ConclusionCSS combined with TXA was more effective than TXA alone in reducing perioperative blood loss and inflammatory response and did not increase the incidence of thromboembolism complications.     

The Effect of Tranexamic Acid on Transfusion Rate in Primary Total Hip Arthroplasty

Total hip arthroplasty (THA) may produce blood loss requiring allogenic blood transfusion. Recently several authors have reported success decreasing their transfusion rate with tranexamic acid (TXA). We retrospectively reviewed our last 1595 primary THA in 1494 patients looking at whether the patients received TXA via IV infusion, topical application, or neither, and the need for a blood transfusion. Infusion of TXA acid produced a statistically significant difference in transfusion rate (p < 0.001) while topical TXA failed to reach statistical significance (P = 0.15). The transfusion rate without TXA was 19.86%, 4.39% with TXA infusion (odds ratio = 5.36), and 12.86% (odds ratio = 1.67) with topical TXA.     

Risk factors for blood transfusion after revision shoulder arthroplasty

BackgroundHigher blood transfusion rates have been reported in revision shoulder arthroplasty than in primary arthroplasty. This study seeks to evaluate factors associated with blood transfusions after revision shoulder arthroplasty and to evaluate the effectiveness of tranexamic acid (TXA) to reduce blood transfusion rates in revision shoulder arthroplasty.MethodsAll shoulder arthroplasties performed at one institution were retrospectively reviewed using a research database over two time periods: before (November 2011 to November 2012) and after (April 2015 to April 2017) a protocol for the use of TXA was implemented. The inclusion criterion was any revision shoulder arthroplasty performed during the study time periods. Demographic, preoperative, intraoperative, and postoperative factors were reviewed and compared based on transfusion. Patients who received TXA were compared with those patients who did not. Two-tailed Fisher exact tests, unpaired Welch’s t-tests, and multivariate logistic regression analysis were used to compare groups.ResultsA total of 135 revision shoulder arthroplasties were performed and evaluated during the study period. The overall transfusion rate for revision shoulder arthroplasty was 14.1%. Preoperative hematocrit (Hct) <42 was associated with a higher transfusion rate (18% vs. 5%; P = .03) on univariate analysis. Patients who received a transfusion had a significantly longer length of hospital stay (4.3 vs. 2.0 nights; P < .001). After controlling for covariates in the multivariate analysis, gender, body mass index, heart disease, diabetes mellitus, a history of a bleeding disorder, American Society of Anesthesiologists score, surgery type, and humeral stem retention were not individually associated with the need for a blood transfusion. A higher estimated blood loss was associated with a higher risk of blood transfusion (odds ratio, 2.04 per 100 mL increase; P < .001). On multivariate analysis, a one-unit decrease in preoperative Hct increased the odds of a blood transfusion by 1.20 (P = .03). On multivariate analysis, the use of TXA was associated with a decreased transfusion rate, but this only approached significance (odds ratio, 0.26; confidence interval, 0.05-1.24; P = .09).ConclusionBlood transfusion after revision shoulder arthroplasty is more common in patients with lower preoperative Hct and a higher estimated blood loss on multivariate analysis with an overall transfusion rate of 14%. The use of perioperative TXA was associated with a decreased risk of transfusion, but this only approached significance.     

Oral vs Intravenous vs Topical Tranexamic Acid in Primary Hip Arthroplasty: A Prospective,Randomized, Double-Blind,Controlled Study

Background

Tranexamic acid (TXA) has demonstrated efficacy in reducing blood loss, reduction in hemoglobin, and blood transfusion requirements in primary total hip arthroplasty (THA). The optimal mode of TXA administration for patients undergoing primary THA is unclear. The purpose of this randomized controlled trial is to determine whether oral administration of TXA was superior to intravenous or topical routes in these patients.

The effect of tranexamic acid on hidden bleeding in older intertrochanteric fracture patients treated with PFNA

ObjectiveTo investigate the effect of tranexamic acid (TXA) on hidden bleeding in older intertrochanteric fracture patients treated with intramedullary nails.MethodBetween January 2016 and January 2017, 100 cases of intertrochanteric fractures eligible for the study were treated with proximal femoral nail antirotation (PFNA) in our hospital. All patients were divided into two groups of 50 patients each: the TXA group and a blank control group. In the TXA group, all patients received TXA at a dose of 10 mg/kg⁻¹ intravenously, 10 min preoperatively and 5 h postoperatively. The control group did not receive TXA. We recorded the volume of intraoperative blood loss and postoperative drainage, and the need for postoperative blood transfusion and transfusion volume for all patients. Blood routine examination was performed on the day of surgery and 2 days postoperatively. We calculated the total blood loss and hidden blood loss in the two groups separately according to the Gross equation. All patients underwent deep vein ultrasound of the lower limbs preoperatively and 1 week postoperatively to detect thrombosis.ResultsCompared with controls, patients in the TXA group had lower: overt bleeding (50.59 ml; p = .012), total blood loss (181.58 ml; p = .005), hidden blood loss (130.64 ml; p = .037), volume of blood transfusion (110.0 ml; p = .019), and 20% lower transfusion rate compared with the control group. Patients receiving short-nail fixation had significantly lower hidden blood loss compared with patients receiving long-nail fixation (p < .05). However, we found no statistically significant difference in the incidence of deep vein thrombosis in the lower limbs between the two groups (p = .938).ConclusionTXA significantly reduced hidden blood loss in older intertrochanteric fracture patients treated with intramedullary nails without an increased risk of thrombosis in lower limb deep veins.     

Tranexamic acid in non-elective primary total hip arthroplasty

PurposeBlood loss during and following elective total hip arthroplasty (THA) can be substantial and may require allogeneic blood transfusions which carries significant risks and morbidity for patients. Intraoperative use of tranexamic acid (TXA) has been proven to reduce the need for allogeneic blood transfusion in elective THA patients. Data regarding TXA efficacy in reducing blood loss in trauma patients undergoing non-elective primary THA is sparse, and its routine use is not well established.MethodsThis is a retrospective analysis of a consecutive cohort of patients who underwent non-elective primary THA in a tertiary medical center between January 1st 2011- December 31st 2019. The cohort was divided into two groups; one received perioperative TXA treatment while the other did not. Blood loss, blood product administration, peri and postoperative complications, readmissions and 1-year mortality were compared between groups.ResultsA total of 419 patients (146 males, 273 females) who underwent THA were included in this study. The "TXA" group consisted 315 patients compared to 104 patients in the "no TXA" group. TXA use reduced postoperative bleeding, as indicated by changes in hemoglobin levels before and after surgery (ΔHb= -2.75 gr/dL vs. ΔHb= -3.34 gr/dL, p<0.001) and by administration of allogeneic blood transfusions (7.0% vs. 16.3%, p = 0.004).ConclusionSimilar to the known effect of TXA in elective THA patients, the use of TXA treatment in patients undergoing non-elective THA led to a significant reduction in postoperative blood loss and in the proportion of patients requiring allogeneic blood transfusions.     

Tranexamic acid reduces blood loss in paediatric proximal femoral and/or pelvic osteotomies

PurposeProximal femoral and/or pelvic osteotomies (PFPO) are associated with significant blood loss, which can be harmful, especially in paediatric patients. Therefore, considering methods to reduce blood loss is important. The purpose of this study was to examine the efficacy of tranexamic acid (TXA) in reducing intraoperative estimated blood loss (EBL) in paediatric patients undergoing a PFPO.MethodsPaediatric patients who had a PFPO between 2014 and 2019 were retrospectively reviewed. Outcome measures included patient demographics, TXA use (none, preoperative and/or intraoperative bolus, pump), EBL, transfusion rate and thromboembolic complications. Univariate and multivariate analyses were performed to assess associations between investigated outcome measures and EBL.ResultsA total of 340 PFPO (263 patients) were included. Mean age at surgery was 8.0 years (sd 4.3). In all, 269 patients received no TXA, 20 had a preoperative bolus, 43 had an intraoperative bolus and eight patients had other TXA regimes (preoperative and intraoperative bolus or pump). Overall, mean blood loss was 211 ml (sd 163). Multivariate analysis showed significant associations between higher EBL and higher age at surgery, male sex, higher body mass index and longer procedure time. There was a significant association between lower EBL and a preoperative TXA bolus: 66 ml (33%) less EBL compared with patients without TXA (95% confidence interval -129 to -4; p = 0.04). No thromboembolic complications were reported in any of the studied patients.ConclusionPreoperative TXA administration is associated with a decreased EBL in PFPO. No thromboembolic events were reported. Administering TXA preoperatively appears to be effective in paediatric patients undergoing a PFPO.Level of evidenceLevel III – retrospective comparative study.     

Epsilon Aminocaproic Acid to Reduce Blood Loss and Transfusion After Total Hip and Total Knee Arthroplasty

Background

Total hip and knee arthroplasty (THA and TKA) are associated with significant blood loss and some patients require postoperative blood transfusion. While tranexamic acid has been studied extensively among this population, we tested the hypothesis that epsilon aminocaproic acid (EACA) can reduce blood loss and transfusion after joint arthroplasty.

口服和静脉注射氨甲环酸对于腰椎椎管减压融合术的围手术期失血量影响

目的 ：探讨氨甲环酸（tranexamic acid,TXA）不同给药方式对腰椎椎管减压融合术围手术期失血量、隐性出血量、输血率,以及不良反应等各方面的影响。方法：对2019年7月至2020年7月接受腰椎椎管减压融合术的60例患者进行回顾性分析,根据TXA不同给药方式分为观察组和对照组,每组30例。观察组术前2 h口服2 g TXA;对照组在切皮前5～10 min予以1 g TXA静脉输注,术后6 h予以1 g TXA静脉输注1次。分别记录两组患者术中出血量、术后引流量、总失血量、隐性失血量、引流管拔除时间、输血率、静脉血栓形成率、不良事件发生率,观察术前和术后1、3 d血红蛋白（hemoglobin,Hb）,红细胞比容（hematocrit,HCT）的变化情况。结果：术后1、3 d的Hb及HCT均较术前有明显改善（P<0.01）,但组间比较差异无统计学意义（P>0.05）。两组术中出血量、术后引流量、总失血量、术中失血量、隐性失血量、拔管时间、输血率比较差异无统计学意义（P>0.05）。两组患者均未见静脉血栓形成和不良事件发生。结论：在腰椎椎管减压融合术围手术期口服...     

Topical Tranexamic Acid is Equivalent to Targeted Preoperative Autologous Blood Donation in Total Hip Arthroplasty

Background

Topical tranexamic acid (TXA) was introduced to replace the previous targeted preoperative autologous blood donation (PABD) program. This study aims to analyze the efficacy of topical TXA compared with targeted PABD in anemic patients undergoing primary total hip arthroplasty (THA).

Blood loss and transfusion rate compared among different dosing regimens of tranexamic acid administration in patients undergoing hip hemiarthroplasty for femoral neck fracture: A randomized controlled trial

BackgroundIntravenous tranexamic acid (TXA) administration is a proven safe and effective method for reducing both blood loss and transfusion in total joint arthroplasty. However, data specific to its efficacy in hip hemiarthroplasty (HHA) for femoral neck fracture are scarce. Furthermore, no study has investigated the efficacy of an additional dose of TXA administration. Accordingly, this study aimed to assess blood loss and the transfusion rate compared among different regimens of TXA administration in patients undergoing HHA for femoral neck fracture.MethodsBetween January 2019 to December 2020, 90 HHA patients were randomized into one of three groups (30 patients/group). Control group patients received intravenous normal saline solution (NSS) 20 mL before skin incision, and NSS 20 mL at 3 hours after surgery. one-dose (1D) group patients received 750 mg of intravenous TXA before skin incision, and NSS 20 mL at 3 hours after surgery. Two-dose (2D) group patients received 750 mg of intravenous TXA before skin incision, and 750 mg of TXA at 3 hours after surgery. The primary outcome was blood transfusion rate. Intraoperative blood loss, hemoglobin levels at 24- and 48-hours postoperation, and calculated total blood loss were compared among the three groups.ResultsThe mean age of the study population was 79.7 years, and 76.7% of participants were women. The transfusion rate in the control, 1D and 2D groups was 43.3%, 16.7%, and 3.3%, respectively. Total hemoglobin loss; total red blood cell loss; intraoperative blood loss; hemoglobin level at 24- and 48-hours postoperation; change in hemoglobin level between 0 and 24 hours, and between 0 and 48 hours; blood transfusion rate; and, the number of patients who did not require blood transfusion were all significantly improved in the 2D group compared to baseline. No parameters were significantly improved in the 1D group compared to controls.ConclusionsThe results of this study demonstrate both the efficacy of TXA administration in HHA, and the superiority of two-dose TXA administration over one-dose TXA administration in HHA for femoral neck fracture.     

Blood Management Following Total Joint Arthroplasty in an Aging Population: Can We Do Better?

BackgroundTo evaluate the transfusion rates for octogenarians and nonagenarians following total knee and hip arthroplasty (TKA, THA), we compared transfusion rates and associated risk factors among sexagenarians, septuagenarians, octogenarians, and nonagenarians.MethodsThis retrospective cohort study included 13,603 sexagenarians, 9796 septuagenarians, 2706 octogenarians, and 158 nonagenarians that received a primary, unilateral THA or TKA between 2016 and 2020 at a high-volume institution. Using multivariable logistic regression analysis, the study analyzed risk factors for postoperative transfusions including use of tranexamic acid (TXA) and compared preoperative and postoperative hemoglobin (Hgb) levels and the drop in Hgb.ResultsNonagenarians had significantly higher transfusion rates (THA 25.5%, TKA 26.7%) than octogenarians (THA 9.9%, TKA 9.2%), septuagenarians (THA 3.3%, TKA 4.5%), and sexagenarians (THA 1.9%, TKA 2.9%) (P < .01). Significant risk factors for transfusion requirement following THA were American Society of Anesthesiologists level III (odds ratio [OR] 5.3, P < .01) and American Society of Anesthesiologists level IV (OR 8.0, P = .01), nonuse of TXA (intravenous: OR 0.3, P < .01; topical: OR 0.5, P < .01), lower preoperative Hgb levels (OR 0.4, P < .01), longer duration of surgery (OR 1.0, P < .01), and hepatopathy (OR 3.1, P < .01). Significant risk factors following TKA were nonuse of TXA (intravenous: OR 0.3, P < .01; topical: OR 0.5, P < .01; combined: OR 0.2, P < .01), lower preoperative Hgb levels (OR 0.4, P < .01), and longer surgery time (OR 1.0, P < .01).ConclusionThe strongest independent risk factors for increased transfusion rates among octogenarians and nonagenarians were lack of TXA application and lower preoperative Hgb levels. Routine TXA application and preoperative patient optimization are recommended to reduce transfusion rates in patients aged 80+.     

Tranexamic Acid Administration Is Not Associated With an Increase in Complications in High-Risk Patients Undergoing Primary Total Knee or Total Hip Arthroplasty: A Retrospective Case-Control Study of 38,220 Patients

BackgroundTranexamic acid (TXA) administration to reduce postoperative blood loss and transfusion is a well-established practice for total knee arthroplasty (TKA) and total hip arthroplasty (THA). However, clinical concerns remain about the safety of TXA in patients with a history of a prothrombotic condition. We sought to determine the risk of complications between high-risk and low-risk TKA and THA patients receiving TXA.MethodsWe retrospectively reviewed 38,220 patients (8877 high-risk cases) who underwent primary TKA and THA between 2011 and 2017 at our institution. Intravenous TXA was administered in 20,501 (54%) of cases. The rates of thrombotic complications (deep vein thrombosis [DVT], pulmonary embolism [PE], myocardial infarction [MI], and cerebrovascular accident [CVA]) as well as mortality and readmission were assessed at 90 days postoperatively. Additionally, we evaluated 90-day postoperative occurrence of DVT and PE separate from occurrence of MI and CVA. Patients were categorized as high risk if they had a past medical history of a prothrombotic condition prior to surgery.ResultsThere was no significant difference in the odds of these adverse outcomes between high-risk patients who received TXA and high-risk patients who did not receive TXA (odds ratio [OR] 1.00, 95% confidence interval [CI] 0.85-1.18). There were also no differences when evaluating the odds of 90-day postoperative DVT and PE (OR 0.84, 95% CI 0.59-1.19) nor MI and CVA (OR 0.91, 95% CI 0.56-1.49) for high-risk patients receiving TXA vs high-risk patients who did not receive TXA.ConclusionTXA administration to high-risk TKA and THA patients is not associated with a statistically significant difference in adverse outcomes. We present incremental evidence in support of TXA administration for high-risk patients undergoing primary arthroplasties.
