TY - JOUR. T1 - The effect of tranexamic acid on hemoglobin levels during total knee arthroplasty. AU - Pachauri, Amit. AU - Acharya, Kiran K.. AU - Tiwari, Akhilesh Kumar. PY - 2014/1/1. Y1 - 2014/1/1. N2 - The aim of this study was to evaluate the efficacy of perioperative administration of 1,4-aminocarboxylic acid (tranexamic acid) in reducing the intraoperative and postoperative blood loss in patients undergoing total knee replacement (TKR). Tranexamic acid is an antifibrinolytic agent that is 7-10 times as potent as epsilon aminocaproic acid. We had investigated the effect of tranexamic acid on blood loss intraoperatively and postoperatively during and after TKR thereby significantly preventing a decrease in postop Hb in these patients. This study was a randomized, prospective, observational, double-blinded study on 99 patients, after obtaining ethical committee approval and valid informed consent from patients to be part of the study. In the study group, the drug was administered in 2 ...
Antifibrinolytic medications such as tranexamic acid, aprotinin, and aminocaproic acid have proven to be useful in decreasing blood loss and the proportion of patients who require transfusion after a number of surgical procedures. In orthopedic surgery, tranexamic acid (TXA) is the best studied of these medications and a recent Cochrane Database review determined that tranexamic acid was effective in decreasing perioperative bleeding and post-operative transfusion after elective hip replacement and knee replacement surgery. At Mayo Clinic Rochester, the routine administration of tranexamic acid has evolved over the past decade to become part of the typical protocol for more than 3,000 elective hip and knee replacement procedures each year. Recent administrative data provides fairly compelling evidence of the efficacy of tranexamic acid in decreasing transfusion at the Mayo Clinic Rochester practice with 2010 data showing 2% and 7% prevalence of transfusion in patients treated with tranexamic ...
Product Name: Tranexamic Acid Injection. Common Name: antifibrinolytic injection. Strength: 100 mg / ml. Description: Tranexamic acid belongs to the class of medications called antifibrinolytic agents. Tranexamic acid (TXA) is a medication used to treat or prevent excessive blood loss from trauma, surgery, and in various medical conditions including hemophilia and heavy menstrual bleeding. It comes in oral and intravenous forms.. Indications and Usage:. Tranexamic acid medication is used to prevent or reduce bleeding in certain conditions, such as dental surgery in people with hereditary blood clotting disorders, cervical surgery, heavy menstrual bleeding, nose bleeds and bleeding inside the eye.. In some medical conditions, the body breaks down blood clots too fast, not allowing the bleeding to stop and the wound to heal. Tranexamic acid works by blocking the breakdown of clots in the body..

Risk Summary. Available data from published studies, case series and case reports with tranexamic acid use in pregnant women in the second and third trimester and at the time of delivery have not clarified whether there is a drug-associated risk of miscarriage or adverse maternal or fetal outcomes. There are 2 (0.02%) infant cases with structural abnormalities that resulted in death when tranexamic acid was used during conception or the first trimester of pregnancy; however, due to other confounding factors the risk of major birth defects with use of tranexamic acid during pregnancy is not clear. Tranexamic acid is known to pass the placenta and appears in cord blood at concentrations approximately equal to maternal concentration (see Data).. Reproduction studies performed in mice, rats, and rabbits have not revealed any adverse effects on the fetus due to tranexamic acid administered during organogenesis. Doses examined were multiples of up to 3 times (mouse), 6 times (rat), and 3 times ...
Study Objectives: The current study will assess the effect of tranexamic acid on intraoperative bleeding and surgical outcomes during functional endoscopic sinus surgery.. Background: Tranexamic acid is an antifibrinolytic that prevents the activation of plasminogen to plasmin. Plasmin is responsible for the degradation of fibrin clots. This is the mechanism by which tranexamic acid prevents blood clot breakdown and reduces operative bleeding. Functional endoscopic sinus surgery, or FESS, is a widely used surgical technique to treat sinusitis and other diseases of the nose and nasal cavities. Bleeding during FESS can hinder surgical progress and has been associated with an increase in complications.. Methods: The current study is randomized, double-blind and placebo- controlled. Study sample size will be calculated based on a previous study of topical intranasal TA. Participants undergoing functional endoscopic sinus surgery will be recruited for the study during a preoperative outpatient clinic ...
Tranexamic acid (TXA) is a medication used to treat or prevent excessive blood loss from major trauma, post partum bleeding, surgery, tooth removal, nose bleeds, and heavy menstruation.[1][2] It is also used for hereditary angioedema.[1][3] It is taken either by mouth or injection into a vein.[1]. Side effects are rare.[3] Some include changes in color vision, blood clots and allergic reactions.[3] Greater caution is recommended in people with kidney disease.[4] Tranexamic appears to be safe for use during pregnancy and breastfeeding.[3][5] Tranexamic acid is in the antifibrinolytic family of medications.[4]. Tranexamic acid was discovered in 1962 by Utako Okamoto.[6] It is on the World Health Organizations List of Essential Medicines, the most effective and safe medicines needed in a health system.[7] Tranexamic acid is available as a generic medication.[8] The wholesale cost in the developing world is about 4.38 to 4.89 USD for a course of treatment.[9] In the United States a course of ...

Background:Proximal Femoral shaft fractures are commonly associated with marked blood loss which can lead topostoperative acute anemia and some other complications.Tranexamic acid (TA) is an antifibrinolytic medication that reduces intra-and postoperative blood loss and transfusionrequirements during some elective surgeries (1-3).The aim of this study is to evaluate the effect of intravenous Tranexamic acid (TA) on intraoperative blood loss and asubsequent need for transfusion in patients who were undergoing surgery for femoral shaft fractures in trauma setting.Methods:Thirty-eight ASA grade I-II patients undergoing proximal femoral shaft fracture surgery with intra medullarynailing were included in this double blind randomized controlled clinical trial. They were allocated into two groups. GroupI, the intervention group with eighteen patients received 15 mg/kg (TA) via intravenous infusion before surgical incision.Patients in the placebo group received an identical volume of normal saline.Hemoglobin
Tranexamic Acid is only found in individuals that have used or taken this drug. It is an antifibrinolytic hemostatic used in severe hemorrhage. [PubChem]Tranexamic acid competitively inhibits activation of plasminogen (via binding to the kringle domain), thereby reducing conversion of plasminogen to plasmin (fibrinolysin), an enzyme that degrades fibrin clots, fibrinogen, and other plasma proteins, including the procoagulant factors V and VIII. Tranexamic acid also directly inhibits plasmin activity, but higher doses are required than are needed to reduce plasmin formation ...
Background and Aims: Tranexamic acid has been used to decrease blood loss volumes and the subsequent need for blood transfusion in the orthopedic, spinal and cardiac surgeries. Methods: In this prospective controlled randomized clinical trial study, 24 candidates for orthognathic surgeries received tranexamic acid (20 mg/kg) intravenously just before the surgery while matched control patients received normal saline. The patients underwent the surgeries according to the standard protocol. Patients blood hemoglobin and hematocrit levels were calculated before and after the surgeries and blood loss volumes were calculated using these criteria. Results: The blood loss was estimated as 693.65 ± 81.24 and 1024.00 ± 75.41 ml regarding blood hemoglobin values before and after the surgery in intervention and control groups, respectively; while it was estimated as 660.93 ± 62.78 and 1052.00 ± 48.54 ml concerning patients blood hematocrit levels before and after the surgery in those groups, respectively.

The evidence in this review suggests that the uncertainty about the effect of tranexamic acid on blood transfusion in surgical patients was resolved over a decade ago; however, uncertainties about its effect on thromboembolic events and mortality persist. Despite this, trials of tranexamic acid continue to assess the effect on blood transfusion. One reason may be a reluctance to generalise the evidence across surgery types, although there is no evidence that the relative effect of tranexamic acid on blood transfusion varies by type of surgery. A second reason may be that trialists are unaware of the existing evidence when initiating a new trial. Our observation that only half of the trials cited one or more of the available systematic reviews and just two carried out their own systematic review, does suggest that many trialists are indeed failing to adequately consider the existing evidence.. Blood is a scarce and costly resource and blood transfusion is not without risk. The cost of a unit of ...
The risk-benefit balance of using tranexamic acid in cardiac surgical patients remains unclear. While tranexamic acid reduces the risk of bleeding among patients undergoing cardiac surgery, there are concerns that it may have prothrombotic and proconvulsant effects. In a trial with a 2-by-2 factorial design, patients scheduled to undergo coronary-artery surgery and at risk for perioperative complications were randomly allocated to receive aspirin or placebo and tranexamic acid or placebo. The results of the tranexamic acid comparison are reported here. The primary outcome was a composite of death and thrombotic complications (nonfatal myocardial infarction, stroke, pulmonary embolism, renal failure, or bowel infarction) within 30 days after surgery. Four thousand six hundred thirty-one patients underwent surgery and had available outcome data. A primary outcome event occurred in 386 patients (16.7%) in the tranexamic acid group and in 420 patients (18.1%) in the placebo group (relative risk, ...

Abstract Bilateral total knee arthroplasty (BTKA) patients may require blood transfusion which has its risks. Anti-fibrinolytic drugs such as aprotinin, aminocaproic acid and tranexamic acid (TXA) have reduced transfusion requirements in major surgery. This retrospective audit was performed to assess effectiveness of TXA in reducing blood transfusion rate in single-stage sequential BTKA cases operated by a single surgeon. Records of 91 patients given TXA and 80 controls who were operated before 2012 and not given TXA were reviewed. TXA was given 15mg/kg intravenously (IV) before tourniquet deflation and 3 hours postoperatively.Blood transfusion was done in 9(10%) patients in the TXA group compared to 20(25%)in the control group (p|0.01). One (1.25%) patient in the control group had non-fatal pulmonary embolism.TXA appeared to be effective in decreasing post-operative blood loss and requirement for blood transfusion after single-stage BTKA.
BACKGROUND The objective of this meta-analysis was to evaluate the efficacy and safety of tranexamic acid (TXA) in shoulder arthroplasty (SA). METHODS Academic articles were identified from the Cochrane Library, Medline (1966-2017.2), PubMed (1966-2017.2), Embase (1980-2017.2), and ScienceDirect (1966-2017.2). Randomized controlled trials (RCTs) and non-RCTs studying TXA in SA were included. Two independent reviewers conducted independent data abstraction. The I statistic was used to assess heterogeneity. Fixed- or random-effects models were used for meta-analysis. RESULTS Two RCTs and 2 non-RCTs met the inclusion criteria. This meta-analysis found significant differences in postoperative hemoglobin reduction (MD = -0.71 g/dL), drainage volume (MD = -133.21 mL), and total blood loss (MD = -226.82 mL) between TXA groups and controls. There were no significant differences in blood transfusion requirements, operation time, or length of hospital stay. CONCLUSIONS The use of TXA in SA decreases

2017 The American Society of Colon and Rectal Surgeons, Inc. BACKGROUND: Lower GI hemorrhage is a common source of morbidity and mortality. Tranexamic acid is an antifibrinolytic that has been shown to reduce blood loss in a variety of clinical conditions. Information regarding the use of tranexamic acid in treating lower GI hemorrhage is lacking. OBJECTIVE: The aim of this trial was to determine the clinical efficacy of tranexamic acid when used for lower GI hemorrhage. DESIGN: This was a prospective, double-blind, placebo-controlled, randomized clinical trial. SETTINGS: The study was conducted at a tertiary referral university hospital in Australia. PATIENTS: Consecutive patients aged ,18 years with lower GI hemorrhage requiring hospital admission from November 2011 to January 2014 were screened for trial eligibility (N = 265). INTERVENTIONS: A total of 100 patients were recruited after exclusions and were randomly assigned 1:1 to either tranexamic acid or placebo. MAIN OUTCOME MEASURES: The ...
The purpose of this meta-analysis is to evaluate the efficacy and safety of tranexamic acid (TXA) for patients with degenerative lumbar disc herniation, stenosis or instability undergoing posterior lumbar fusion (PLF) surgery. We searched PubMed, Embase, and Cochrane Library until May 1, 2018. Two reviewers selected studies, assessed quality, extracted data, and evaluated the risk of bias independently. Weighted mean difference (WMD) and relative risk (RR) were calculated as the summary statistics for continuous data and dichotomous data, respectively. We chose fixed-effects or random-effects models based on I2 statistics. RevMan 5.0 and STATA 14.0 software were used for data analysis. Nine studies enrolling 713 patients for the study. The pooled outcomes demonstrated that TXA can decrease total blood loss (TBL) in patients underwent PLF surgery [WMD = -250.68, 95% CI (− 325.06, − 176.29), P|0.001], intraoperative blood loss (IBL) [WMD = -72.57, 95% CI (− 103.94, − 41.20), P|0.001],

The early administration of tranexamic acid (TXA) to bleeding trauma patients reduces all-cause mortality without increasing the risk of vascular occlusive events. Indeed, the risk of arterial thrombosis appears to be reduced with TXA. In this commentary we hypothesize that TXA has an antithrombotic effect and explore potential mechanisms. These include inhibition of the inflammatory effects of plasmin, effects on platelets and effects on factors V and VIII. If proven, these antithrombotic effects would have major implications for the systemic use of TXA in surgical patients, where TXA has been clearly shown to reduce bleeding.

BACKGROUND and OBJECTIVE:. Searching for the ideal pleurodesis agent still continues, Bleomycin is one of the most commonly used agents for pleurodesis. Tranexamic acid have been reported as a cheap pleurodesis agent by many authors. In this study, we evaluate the efficacy, safety and cost of using a combination of bleomycin and Tranexamic acid versus each agent alone.. METHODS:. Sixty three patients with massive malignant pleural effusions were divided in 3 equal groups in a simple randomized manner. Tranexamic acid (30 mg/kg [maximum of 2 g] in 50 mL of normal saline) was administered through a chest tube in Group 1. Group 2 received bleomycin (1 U/kg [maximum of 60 U] in 70 mL of normal saline). Group 3 received the above 2 preparations (tranexamic acid, 30 mg/kg [maximum of 2 g] in 40 mL of normal saline and bleomycin, 1 U/kg [maximum of 60 U] in 50 mL of normal saline) instilled one following the other by 15 minutes. Follow-up CXR examinations were performed at 7 days, 30 days, 60 days and ...

Despite having many studies to evaluate the role of TXA in surgeries, limited literature is available on its role in hip fracture surgeries. In an RCT, TXA was administered as an initial bolus dose of 500mg before surgery followed by continuous infusion at 1mg/kg/h for the duration of surgery. Results showed that the differences in mean reduction in Hb and mean volume of blood loss postoperatively between TXA and placebo groups were significant. In addition, only 7 out of 45 patients in TXA group required blood transfusion compared to 18 out of 45 in placebo group and the difference was again significant.5 On the contrary, another RCT in 2010 concluded that there was no significant difference in blood transfusion rates between TXA and placebo groups after surgery for hip fracture.3 Therefore, although effectiveness of TXA in reducing post-surgical blood loss and transfusion requirements have been shown by multiple studies, but its effectiveness, specifically in hip fracture surgeries, is yet to ...
BACKGROUND: Tranexamic acid reduces surgical bleeding and decreases mortality in patients with traumatic extracranial bleeding. Intracranial bleeding is common after traumatic brain injury (TBI) and can cause brain herniation and death. We aimed to assess the effects of tranexamic acid in patients with TBI. METHODS: This randomised, placebo-controlled trial was done in 175 hospitals in 29 countries. Adults with TBI who were within 3 h of injury, had a Glasgow Coma Scale (GCS) score of 12 or lower or any intracranial bleeding on CT scan, and no major extracranial bleeding were eligible. The time window for eligibility was originally 8 h but in 2016 the protocol was changed to limit recruitment to patients within 3 h of injury. This change was made blind to the trial data, in response to external evidence suggesting that delayed treatment is unlikely to be effective. We randomly assigned (1:1) patients to receive tranexamic acid (loading dose 1 g over 10 min then infusion of 1 g over 8 h) or ...

The TXA and placebo groups were compared with respect to demographics, baseline characteristics, intraoperative and postoperative laboratory and vital data, thromboelastography data, the amount of blood loss, PRBC transfusion, and length of stay in the intensive care unit and hospital. The distribution of all continuous variables that followed a normal Gaussian distribution as assessed by the Kolmogorov-Smirnov Lilliefors goodness-of-fit test26 are presented as mean ± SD and compared between groups by the two-sample Student t test. Mean differences in total blood loss and PRBC transfused between the two groups were described with 95% confidence intervals. Categorical data, such as gender, race, American Society of Anesthesiologists (ASA) physical status, and presence of increased intracranial pressure, were compared by the Pearson chi-square test. Continuous data not conforming to a normal distribution because of skewness, including length of stay and units of transfused blood, are reported ...

A growing body of evidence has shown tranexamic acid (TXA) to be effective in decreasing perioperative blood loss and transfusion requirements in both primary and revision hip and knee arthroplasty.
All adult trauma patients who are considered to be at risk of significant haemorrhage and are within 8 hours of the injury, are eligible for trial entry if they appear to be at least 16 years old. There are no other pre-specified exclusion criteria, as the fundamental eligibility criterion is the responsible doctors uncertainty whether or not to use tranexamic acid (TXA) in a particular adult with traumatic haemorrhage. Patients for whom there is considered by the responsible doctor to be a clear indication for TXA should not be randomised. Likewise, any for whom there is considered to be a clear contraindication to TXA (such as, perhaps, those who have clinical evidence of a thrombotic disseminated intravascular coagulation) should not be randomised. All those for whom the responsible doctor is substantially uncertain as to whether or not to use an anti-fibrinolytic agent are eligible for randomisation, and as many such patients as possible should be considered for the trial. ...

This guideline covers care before, during and after a planned knee, hip or shoulder replacement. It includes recommendations on preoperative rehabilitation, anaesthesia, tranexamic acid to minimise blood loss, preventing infection, and postoperative rehabilitation, among others.
You really were paying attention! Full circle we come. Although blood is not all things to everybody, and has its own negatives and caveats, at the present date if you lose blood the best replacement is blood. Of some kind.. Of what kind remains a bit of a mystery. Men in white coats continue to play with different mixtures of red cells, and plasma, and platelets, and even various concentrates and precipitates of specific clotting factors. One of the latest miracle additions is tranexamic acid, which antagonizes natural thrombolytics (remember plasmin?) and seems to reduce bleeding. There are also cool devices, used mainly during surgery, that "salvage" your own lost blood, rinse it off, and give it right back to you, which obviously simplifies some things.. Of note is an approach to transfusion developed by the anaesthesiologists at Shock Trauma in Baltimore. They like to give PRBCs and plasma until you reach a reasonably permissive pressure. Then they bolus some opiate goodness (fentanyl is ...
Delivering therapeutics deep into damaged tissue during bleeding is challenging because of the outward flow of blood. When coagulants cannot reach and clot blood at its source, uncontrolled bleeding can occur and increase surgical complications and fatalities. Self-propelling particles have been proposed as a strategy for transporting agents upstream through blood. Many nanoparticle and microparticle systems exhibiting autonomous or collective movement have been developed, but propulsion has not been used successfully in blood or used in vivo to transport therapeutics. We show that simple gas-generating microparticles consisting of carbonate and tranexamic acid traveled through aqueous solutions at velocities of up to 1.5 cm/s and delivered therapeutics millimeters into the vasculature of wounds. The particles transported themselves through a combination of lateral propulsion, buoyant rise, and convection. When loaded with active thrombin, these particles worked effectively as a hemostatic agent ...
