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 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.     

Use of Topical Tranexamic Acid Reduces Direct and Indirect Blood Loss and Transfusion Rates in Revision Total Hip Arthroplasty

Background

In primary total hip arthroplasty (THA), evidence supports the use of tranexamic acid (TXA) as an effective strategy for reducing blood loss, but scant evidence supports its use in revision THA.

Questions/Purposes

We aimed to evaluate whether the use of topical TXA in revision THA is associated with less blood loss and lower transfusion rates and to assess its safety, specifically as it relates to thromboembolic complications.

Methods

In this retrospective comparative study, two groups who underwent revision THA between 2005 and 2017 were defined: 98 patients who received 3 g of topical TXA (study group) and 475 patients who did not receive TXA (control group). Subjects were divided into subgroups according to the type of revision. Hemoglobin and hematocrit levels, blood loss, and transfusions were recorded. The follow-up period was 6 weeks.

Results

Median estimated blood loss, hidden blood loss, hemoglobin drop, and transfusion rates were significantly lower in the study group. The rates of post-operative thromboembolism were similar in the two groups. According to subgroup analysis, patients with revision of the femoral component, both components, and staged exchange revisions showed significantly lower rates of transfusion.

Conclusion

Topical TXA administration during revision THA effectively reduced direct and indirect blood loss, including hidden losses, without increasing the rates of thromboembolic events. This effect appeared to be enhanced when the femoral component was revised.

     

The Effect of Tranexamic Acid on Blood Loss and Transfusion Rate in Primary Total Knee Arthroplasty

Allogeneic blood transfusions remain common in primary total knee arthroplasty. We reviewed our experience with 2269 consecutive primary total knee arthroplasties in 2069 patients over a 3.5 year period. In our cohort, 1838 received no TXA, 330 received TXA via IV infusion, and 130 had TXA applied topically. The need for blood transfusion, as well as hematocrit levels immediately after surgery in the recovery room and the day of discharge were recorded. Tranexamic acid infusion demonstrated a statistically significant decrease in blood transfusion (P = 0.001), as did topical application of TXA (P = 0.019). The transfusion rate without TXA was 6.5% (120/1839) but only 0.3% (1/330) with TXA infusion. There were no transfusions (0/130) with topical TXA. Statistical differences were also noted in both immediate post operative and day of discharge hematocrit levels in patients having TXA infusion while those values for patients with TXA irrigation failed to obtain statistical significance. No significant change in the rate of symptomatic deep venous thrombosis or pulmonary embolism was noted.     

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.     

Topical Tranexamic Acid Reduces Blood Loss and Transfusion Rates in Total Hip and Total Knee Arthroplasty

The objective of this study was to determine if tranexamic acid (TXA) applied topically reduced postoperative bleeding and transfusion rates after primary total hip arthroplasty (THA) and primary total knee arthroplasty (TKA). Two hundred and ninety consecutive patients from a single surgeon were enrolled. In TKA, TXA solution was injected into the knee after closure of the arthrotomy. In THA, the joint was bathed in TXA solution at three points during the procedure. In both THA and TKA the TXA solution was at a concentration of 3 g TXA per 100 mL saline. The mean blood loss was significantly higher in the non-TXA patients in both TKA and THA groups. Postoperative transfusions decreased dramatically with TXA, dropping from 10% to 0%, and from 15% to 1%, in the TKA and THA groups, respectively. Topical application of TXA significantly reduces postoperative blood loss and transfusion risk in TKA and THA.     

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.

Combination of Intravenous and Topical Application of Tranexamic Acid in Primary Total Knee Arthroplasty: A Prospective Randomized Controlled Trial

This study was aimed to determine the efficacy and safety of combined intravenous (IV) and topical application of tranexamic acid (TXA) in unilateral total knee arthroplasty (TKA) compared with the IV-TXA. One hundred eight-four patients were enrolled. Participants received either 3 g of IV-TXA or 1.5 g topical TXA combined with 1.5 g IV-TXA. The results revealed that compared with the 3 g IV-TXA, adding 1.5 g topical TXA to 1.5 g IV-TXA in unilateral TKA can have the similar effectiveness in reducing transfusion rate and total blood loss without sacrificing safety. The most important is that by adding topical TXA, patients can gain a smaller maximum decline of hemoglobin (Hb), less drainage volume, less postoperative knee pain, less knee swelling, shorter length of hospital stays and higher short-term satisfaction.     

Comparison of Intravenous versus Topical Tranexamic Acid in Total Knee Arthroplasty: A Prospective Randomized Study

The purpose of this study was to compare the efficacy of topical Tranexamic Acid (TXA) versus Intravenous (IV) Tranexamic Acid for reduction of blood loss following primary total knee arthroplasty (TKA). This prospective randomized study involved 89 patients comparing topical administration of 2.0 g TXA, versus IV administration of 10 mg/kg. There were no differences between the two groups with regard to patient demographics or perioperative function. The primary outcome measure, perioperative change in hemoglobin level, showed a decrease of 3.06 ± 1.02 in the IV group and 3.42 ± 1.07 in the topical group (P = 0.108). There were no statistical differences between the groups in preoperative hemoglobin level, lowest postoperative hemoglobin level, or total drain output. One patient in the topical group required blood transfusion (P = 0.342). Based on our study, topical Tranexamic Acid has similar efficacy to IV Tranexamic Acid for TKA patients.     

Comparison of 3 Routes of Administration of Tranexamic Acid on Primary Unilateral Total Knee Arthroplasty: A Prospective,Randomized, Controlled Study

Background

The mode of administration for tranexamic acid (TXA) to significantly reduce the decrease in hemoglobin (Hb), number of transfusions, relevant costs, and side effects in patients undergoing primary unilateral total knee arthroplasty (TKA) has not been resolved.

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.

Topical Application of Tranexamic Acid Can Reduce Postoperative Blood Loss in Calcaneal Fractures: A Randomized Controlled Trial

The traditional lateral “L” approach is common for managing calcaneal fractures with a drawback of significant blood loss. Yet there are no prospective studies on the hemostatic effect of the topical use of tranexamic acid (TXA) in calcaneal fracture surgeries. The purpose of this study was to evaluate the role of topical administration of TXA in reducing postoperative blood loss in calcaneal fractures. Forty participants were randomly distributed into the TXA group (n = 20) and the control group (n = 20). All participants underwent the same surgery via the lateral “L” approach. At the end of the operation, the surgical wound was irrigated with 80 mL 0.5 g/L TXA in the TXA group and 80 mL 0.9% sodium chloride in the control group, followed by the routine use of a drainage tube when closing the incision. Then, 20 mL 0.5 g/L TXA (TXA group) or 20 mL 0.9% sodium chloride solution (control group) was injected retrogradely into the wound through the drainage tube, which was clipped for 30 minutes thereafter. There were no significant differences in the baseline data between the 2 groups (p > .05). There was significantly less blood loss in the first 24 hours and total blood loss postoperation in the TXA group (p < .01). The surgical wounds healed well after surgery in both groups with no complication. We concluded that topical application of TXA in calcaneal fracture surgeries is a safe and useful method that can reduce postoperative blood loss.     

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.     

Topical administration of tranexamic acid in elderly patients undergoing short femoral nailing for intertrochanteric fracture: A randomised controlled trial

IntroductionTopical application of tranexamic acid (TXA) has been proposed as an alternative to intravenous administration to reduce perioperative bleeding in orthopaedic surgery. The purpose of this randomised controlled trial was to evaluate the efficacy and safety of 1 g topically applied TXA in patients undergoing fixation of intertrochanteric hip fractures by short femoral nailing.MethodsA total of 121 patients were enrolled between May 2018 and January 2020. Patients were randomly allocated (1:1) to receive either 10 mL (1 g) of TXA or 10 mL of normal saline (NS) injected through the subfascial drain following wound closure. Total blood loss, total drain output and blood transfusion requirements up to postoperative day 3 were recorded. Rates of thromboembolic complications and mortality up to 90 days postoperatively were also compared.ResultsThere was no statistically significant difference in total blood loss, total drain output or proportion of patients requiring transfusions. Median total blood loss was 1.088 L (IQR: 0.760–1.795) in the TXA group and 1.078 L (IQR: 0.797–1.722) in the NS group (P = .703). Median total drain output was 60 mL (IQR: 40–140) in the TXA group and 70 mL (IQR: 30–168) in the NS group (P = .696). Blood transfusions were administered in 29 patients (47.5%) in the TXA group and 27 patients (45.0%) in the NS group (P = .782). There was also no difference in frequency of thrombotic complications or mortality within 90 days. There were five thrombotic events in the TXA group and four in the NS group (P = .751). The 90-day mortality rate was 6.6% (4 patients) in the TXA group and 3.3% (2 patients) in the NS group (P = .680).ConclusionA 1 g dose of topically administered TXA did not produce any difference in blood loss, transfusion requirements, thromboembolic complications, or 90-day mortality. Future trials may consider the effect of larger doses in patients undergoing hip fracture fixation surgery.     

Oral Tranexamic Acid Reduces Transfusions in Total Knee Arthroplasty

Background

Tranexamic acid (TXA) reduces intraoperative blood loss and transfusions in patients undergoing total knee arthroplasty. Although numerous studies demonstrate the efficacy of intravenous and topical TXA in these patients, few demonstrate the effectiveness and appropriate dosing recommendations of oral formulations.

Randomized Blinded Study Comparing a Bipolar Sealer and Standard Electrocautery in Reducing Transfusion Requirements in Anterior Supine Intermuscular Total Hip Arthroplasty

Managing blood loss in total hip arthroplasty (THA) minimizes complications and decreases cost. Tissue-sparing anterior supine intermuscular THA (ASI-THA) may offer a quicker recovery but increases blood loss and transfusion requirements. This double-blinded prospective study compared a bipolar sealer (Aquamantys 6.0 bipolar sealer) to standard monopolar electrocautery in reducing blood loss in ASI-THA. Differences in calculated actual blood loss (ABL), hemoglobin, and transfusion requirements were examined. One hundred hips were randomized to each group. Transfusion rates were similar, 6% and 4%, respectively (p > 0.05). ABL and change in hemoglobin were identical (1.35 and 3.3 g). No significant differences in transfusion, blood loss, or hemoglobin were seen with a bipolar sealer device. Routine use of this bipolar sealer device has been discontinued in ASI-THA.     

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).

Topical Administration of Tranexamic Acid in Primary Total Hip and Total Knee Arthroplasty

Major blood loss is a known potential complication in total hip and total knee arthroplasty. We conducted a prospective, stratified, randomized, double-blind, placebo-controlled trial that evaluated 100 patients undergoing total knee or total hip arthroplasty to evaluate the effect on blood loss using the topical application of tranexamic acid. Participants received either 2 g of topical tranexamic acid or the equivalent volume of placebo into the joint prior to surgical closure. Tranexamic acid resulted in a lower mean maximum decline in postoperative hemoglobin levels when compared to placebo (P = 0.013). Patients in the tranexamic acid group demonstrated an improved but non-significant reduction in the units of blood transfused compared to placebo (P = 0.423). There was no clinically significant increase in complications in the tranexamic acid group, including no incidence of venous thromboembolism.     

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 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.
