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.     

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.

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.     

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

The efficaciousness of topical tranexamic acid use at the end of knee arthroplasty surgery to reduce blood loss and transfusion requirements has previously been shown. The aim of this study was to retrospectively assess the effectiveness of topical tranexamic acid use, comparing 155 patients undergoing hip and knee arthroplasty surgery in which tranexamic acid was routinely used, to a group of 149 patients from a similar time frame prior to the introduction of tranexamic acid use. The transfusion rate fell from 19.3% to 2.3% for hip arthroplasty patients and from 13.1% to 0% for knee arthroplasty patients; these differences were significant. We also found significant reductions in haemoglobin loss, blood loss and length of stay of 8 g/L, 244 mL and 1.0 days respectively for hip arthroplasties and 15 g/L, 527 mL and 1.2 days respectively for knee arthroplasties following the introduction of tranexamic acid.     

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.

Tranexamic Acid to Reduce Blood Loss After Bilateral Total Knee Arthroplasty : A Prospective, Randomized Double Blind Study

The effects of 2-dosage regimens of tranexamic acid (10 mg/kg and 15 mg/kg) on blood loss and transfusion requirement were compared to saline placebo in 60 patients undergoing concurrent bilateral total knee arthroplasty, with additional reinfusion autotransfusion from intraarticular drains. Mean blood loss was 462 mL in 15 mL/kg group, 678 mL in 10 mg/kg group, and 918 mL in controls (P < .01 vs 15 mg/kg). Blood available for autotransfusion was greatest in controls and least in 15 mg/kg group. Combined autologous and allogenic transfusion volumes were similar in the treatment groups and significantly less than controls (P < .01). With use of an autologous reinfusion strategy, the lower dose is sufficient to lead to a lesser allogenic transfusion requirement.     

Evaluation of the Efficacy and Safety of Tranexamic Acid for Reducing Blood Loss in Bilateral Total Knee Arthroplasty

Tranexamic acid (TA) has been reported to reduce blood loss after total joint arthroplasty; however, the literature is sparse in evaluating its efficacy in simultaneous bilateral total knee arthroplasty (TKA). In this retrospective study of consecutive patients, TA use in bilateral TKA was associated with a significant reduction in perioperative serum hemoglobin drop, as well as allogeneic blood transfusion needs from 50% to 11% of patients. No autologous blood donation or drains were used. There were no venous thromboembolic events reported. Implementation of a systematic intravenous TA protocol in simultaneous bilateral TKA appears highly effective in reducing transfusion requirements, potentially reducing healthcare resource utilization as well as the morbidity and complications associated with allogeneic blood transfusions.     

The Efficacy of Tranexamic Acid in Total Knee Arthroplasty: A Network Meta-Analysis

Background

A growing body of published research on tranexamic acid (TXA) suggests that it is effective in reducing blood loss and the risk for transfusion in total knee arthroplasty (TKA). The purpose of this network meta-analysis was to evaluate TXA in primary TKA as the basis for the efficacy recommendations of the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and American Society of Regional Anesthesia and Pain Medicine on the use of TXA in primary total joint arthroplasty.

Hypotensive Anesthesia Combined with Tranexamic Acid Reduces Perioperative Blood Loss in Simultaneous Bilateral Total Hip Arthroplasty: A Retrospective Cohort Study

ObjectiveTo assess the efficacy and safety of hypotensive anesthesia (HA) combined with tranexamic acid (TXA) for reducing perioperative blood loss in simultaneous bilateral total hip arthroplasty (SBTHA).MethodsIn this retrospective cohort study, a total of 183 eligible patients (15 females and 168 males, 44.01 ± 9.29 years old) who underwent SBTHA from January 2015 to September 2020 at our medical center were enrolled for analysis. Fifty‐nine patients received standard general anesthesia (Std‐GA group), the other 85 and 39 patients received HA with an intraoperative mean arterial pressure between 70 and 80 mmHg (70–80 HA group) and below 70 mmHg (<70 HA group), respectively. TXA was administrated to all patients. Perioperative blood loss (total, dominant, and hidden), transfusion rate and volume, hemoglobin and hematocrit reduction, duration of operation and anesthesia, length of hospitalization, range of hip motion as well as postoperative complications were collected from hospital''s electronic records and compared between groups.ResultsAll patients were followed for more than 3 months. Total blood loss in the two HA groups (1390.25 ± 595.67 ml and 1377.74 ± 423.46 ml, respectively) was significantly reduced compared with that in Std‐GA group (1850.83 ± 800.73 ml, P < 0.001). Both dominant and hidden blood loss were dramatically decreased when HA was applied (both P < 0.001). Accordingly, the transfusion rate along with volume in 70–80 HA group (14.1%, 425.00 ± 128.81 ml) and <70 HA group (12.8%, 340.00 ± 134.16 ml) were reduced in comparison with those in Std‐GA group (37.3%, 690.91 ± 370.21ml; P = 0.001 and P = 0.014, respectively). The maximal hemoglobin and hematocrit reduction in both HA groups were significantly less than those in Std‐GA group (both P < 0.001). Of note, 70–80 and <70 HA groups exhibited comparable efficacy with no significant differences between them. Besides, significant difference in duration of surgery was found among groups (P = 0.044 and P < 0.001), while no differences in anesthesia time and postoperative range of hip motion were observed. Regarding complications, the incidence of both acute kidney injury and postoperative hypotension in <70 HA group was significantly higher than that in 70–80 HA and Std‐GA groups (P = 0.014 and P < 0.001). Incidence of acute myocardial injury was similar among groups (P = 0.099) and no other severe complications or mortality were recorded.ConclusionThe combination of HA with a mean arterial pressure (MAP) of 70–80 mmHg and TXA could significantly reduce blood loss and transfusion during SBTHA, in addition to shortening operation time and length of hospitalization, and with no increase in complications.     

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.     

Comparison Between Intravenous and Intra-articular Regimens of Tranexamic Acid in Reducing Blood Loss During Total Knee Arthroplasty

Tranexamic acid is an antifibrinolytic drug used widely to prevent bleeding. Its use in reducing bleeding during total knee arthroplasty surgery is well proven but there is no final consensus regarding the regimen. The purpose of our study was to compare the effectiveness of intravenous and intra-articular regimen of tranexamic acid during the total knee arthroplasty surgery. A total of 40 patients were received three doses of intravenous tranexamic acid during total knee arthroplasty surgery. Intra-articular tranexamic acid was used in 40 patients during the surgery. We concluded that intra-articular tranexamic acid is equally effective as three dose intravenous regimen in reducing blood loss during total knee arthroplasty surgery.     

A Prospective Study on Role of Tranexamic Acid in Reducing Postoperative Blood Loss in Total Knee Arthroplasty and Its Effect on Coagulation Profile

Total knee arthroplasty(TKA) is associated with extensive postoperative blood loss. Despite various studies proving the efficacy of Tranexamic Acid (TEA) with single or multiple boluses of different sizes with or without subsequent infusions, no consensus has been reached on the dose of tranexamic acid to be administered or the duration of treatment. In this study, we have investigated in a homogenous healthy population undergoing total knee arthroplasty, if administration of a high dose of tranexamic acid has a blood sparing effect. They were found to be significant with high power concluding a decrease in total blood loss in patients who were administered Tranexamic Acid (TEA) during Total Knee Arthroplasty (TKA). A dose regimen of 15 mg/kg every 8 h for 24 h would seem appropriate as longer administration of TEA was not accompanied by further reduction in blood loss.     

Intra-Articular Tranexamic Acid Mitigates Blood Loss and Morphine Use After Total Knee Arthroplasty. A Randomized Controlled Trial

Background

Tranexamic acid (TXA) has been widely used in total knee arthroplasty (TKA) for blood loss reduction. Given limited evidence on potential relationship between the TXA and improvement of pain control and functional outcome after TKA, this study aimed at comparing the blood loss, pain scores, morphine consumption, and knee flexion across the TXA administration routes.

Tranexamic Acid for Reduction of Blood Loss During Total Hip Arthroplasty

In this study, we evaluated the hemostatic effects of tranexamic acid (TNA), an antifibrinolytic drug, by examining the timing of its administration during total hip arthroplasty. One hundred seven patients being treated for osteoarthritis of the hip joint were randomly divided into 5 groups based on the timing of TNA administration. The intraoperative blood loss, postoperative blood loss, and hemoglobin of these patients who received TNA at different times during the procedure were monitored. We found that the intraoperative blood loss in the preoperative TNA administration groups was significantly lower than both control and postoperative TNA administration groups. Furthermore, 1 g TNA 10 minutes before surgery and 6 hours after the first administration was most effective for the reduction of blood loss during total hip arthroplasty.     

Liposomal Bupivacaine Versus Traditional Periarticular Injection for Pain Control After Total Knee Arthroplasty

The purpose of this study was to compare a novel liposomal bupivacaine to traditional peri-articular injection (PAI) in a multi-modal pain protocol for total knee arthroplasty (TKA). A retrospective cohort study compared 85 consecutive patients undergoing TKA with a traditional PAI of ropivacaine, epinephrine and morphine to 65 patients with a liposomal bupivacaine PAI. After the initial 24 h, inpatient self-reported pain scores were higher in the liposomal bupivacaine group compared to the traditional PAI group (P = 0.04) and a smaller percentage (16.9%) of patients in the liposomal bupivacaine group rated their pain as “mild” compared to the traditional group (47.6%). Liposomal bupivacaine PAI provided inferior pain control compared to the less expensive traditional PAI in a multi-modal pain control program in patients undergoing TKA.     

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.

单次股神经阻滞联合关节腔周围注射在膝关节置换术后镇痛的研究

目的观察单次股神经阻滞联合关节腔周围注射在全膝关节置换术后的镇痛效果。方法选取2017年1月至2018年5月于我院拟行全膝关节置换术的患者共50例,其中男22例,女28例;年龄60~80岁,平均为(69.90±9.46)岁。50例患者随机分为实验组(单次股神经阻滞联合关节腔周围注射组)和对照组(单次股神经阻滞组),每组各25例。比较两组患者术后静息和运动状态视觉模拟评分(visual analogue scale,VAS)、术后膝关节活动度(range of motion,ROM)及不良反应发生情况。结果实验组在术后6 h、12 h、24 h、48 h静息及运动状态VAS评分均比对照组同期VAS评分低,差异有统计学意义(P<0.05);实验组术后1 d、2 d膝关节活动度比对照组同期膝关节活动度高(P<0.05),但术后3 d、7 d两组患者术后膝关节活动度比较差异无统计学意义(P>0.05)。两组患者术后并发症发生率比较差异无统计学意义(P>0.05)。结论对于膝关节置换患者,单次股神经阻滞联合关节腔周围注射比单纯单次股神经阻滞更能缓解患者术后早期的疼痛,有助于患者术后早期行功能锻炼,且不增加术后并发症发生,但对于患者远期功能恢复并无明显优势。
