Relationship of plasmin generation to cardiovascular disease risk factors in elderly men and women. (1/402)

Plasmin-alpha2-antiplasmin complex (PAP) marks plasmin generation and fibrinolytic balance. We recently observed that elevated levels of PAP predict acute myocardial infarction in the elderly, yet little is known about the correlates of PAP. We measured PAP in 800 elderly subjects who were free of clinical cardiovascular disease in 2 cohort studies: the Cardiovascular Health Study and the Honolulu Heart Program. Median PAP levels did not differ between the Cardiovascular Health Study (6.05+/-1.46 nmol/L) and the Honolulu Heart Program (6.11+/-1.44 nmol/L), and correlates of PAP were similar in both cohorts. In CHS, PAP levels increased with age (r=0. 30), procoagulant factors (eg, factor VIIc, r=0.15), thrombin activity (prothrombin fragment F1+2, r=0.29), and inflammation-sensitive proteins (eg, fibrinogen, r=0.44; factor VIIIc, r=0.37). PAP was associated with increased atherosclerosis as measured by the ankle-arm index (AAI) (P for trend, +info)

Usefulness of D-dimer, blood gas, and respiratory rate measurements for excluding pulmonary embolism. (2/402)

BACKGROUND: A study was undertaken to assess the usefulness of the SimpliRED D-dimer test, arterial oxygen tension, and respiratory rate measurement for excluding pulmonary embolism (PE) and venous thromboembolism (VTE). METHODS: Lung scans were performed in 517 consecutive medical inpatients with suspected acute PE over a one year period. Predetermined end points for objectively diagnosed PE in order of precedence were (1) a post mortem diagnosis, (2) a positive pulmonary angiogram, (3) a high probability ventilation perfusion lung scan when the pretest probability was also high, and (4) the unanimous opinion of an adjudication committee. Deep vein thrombosis (DVT) was diagnosed by standard ultrasound and venography. RESULTS: A total of 40 cases of PE and 37 cases of DVT were objectively diagnosed. The predictive value of a negative SimpliRED test for excluding objectively diagnosed PE was 0.99 (error rate 2/249), that of PaO2 of > or = 80 mm Hg (10.7 kPa) was 0.97 (error rate 5/160), and that of a respiratory rate of < or = 20/min was 0.95 (error rate 14/308). The best combination of findings for excluding PE was a negative SimpliRED test and PaO2 > or = 80 mm Hg, which gave a predictive value of 1.0 (error rate 0/93). The predictive value of a negative SimpliRED test for excluding VTE was 0.98 (error rate 5/249). CONCLUSIONS: All three of these observations are helpful in excluding PE. When any two parameters were normal, PE was very unlikely. In patients with a negative SimpliRED test and PaO2 of > or = 80 mm Hg a lung scan is usually unnecessary. Application of this approach for triage in the preliminary assessment of suspected PE could lead to a reduced rate of false positive diagnoses and considerable resource savings.  (+info)

Tranexamic acid increases peritoneal ultrafiltration volume in patients on CAPD. (3/402)

OBJECTIVE: The preservation of ultrafiltration (UF) capacity is crucial to maintaining long-term continuous ambulatory peritoneal dialysis (CAPD).The aim of the present study was to investigate whether the antiplasmin agent tranexamic acid (TNA) increases UF volume in CAPD patients. PATIENTS AND METHODS: Fifteen patients on CAPD, 5 with UF loss and 10 without UF loss, were recruited for the study. The effect of TNA was evaluated with respect to changes in UF volume, peritoneal permeability, peritoneal clearance, bradykinin (BK), and tissue plasminogen activator (tPA) concentration. SETTING: Dialysis unit of the Saiseikai Central Hospital. RESULTS: In patients with UF loss, 2 weeks of treatment with oral TNA produced a significant increase in UF volume in all subjects (5/5).TNA also produced a significant increase in peritoneal clearances of urea and creatinine (Cr). However, the peritoneal equilibration test (PET) revealed that TNA had no effect on dialysate/plasma (D/P) Cr, Kt/V, or the protein catabolic rate (PCR).TNA also had no effect on net glucose reabsorption. In contrast, significant decreases in BK and blood tPA concentrations in response to TNA treatment were noted. BK concentration in drainage fluid was also reduced. In the case of patients without UF loss,TNA produced an increase in UF volume in 70% (7/10). However, no differences were found in blood and drainage BK and tPA concentrations between theTNA treatment and nontreatment periods in these patients. A comparison of basal BK and tPA concentration showed that there were no differences in these parameters between patients with UF loss and those without loss of UF. Furthermore,TNA given intraperitoneally to a patient also produced a marked increase in UF volume. CONCLUSION: The present study suggests thatTNA enhances UF volume in patients both with and without UF loss. SinceTNA did not affect peritoneal permeability and glucose reabsorption, the mechanism by which TNA exerts an enhancing action on UF is largely unknown. We speculate that it may be associated with suppression of the BK and/or tPA system, at least in patients with UF loss.  (+info)

Randomised controlled trial of educational package on management of menorrhagia in primary care: the Anglia menorrhagia education study. (4/402)

OBJECTIVE: To determine whether an educational package could influence the management of menorrhagia, increase the appropriateness of choice of non-hormonal treatment, and reduce referral rates from primary to secondary care. DESIGN: Randomised controlled trial. SETTING: General practices in East Anglia. SUBJECTS: 100 practices (348 doctors) in primary care were recruited and randomised to intervention (54) and control (46). INTERVENTIONS: An educational package based on principles of "academic detailing" with independent academics was given in small practice based interactive groups with a visual presentation, a printed evidence based summary, a graphic management flow chart, and a follow up meeting at 6 months. OUTCOME MEASURES: All practices recorded consultation details, treatments offered, and outcomes for women with regular heavy menstrual loss (menorrhagia) over 1 year. RESULTS: 1001 consultation data sheets for menorrhagia were returned. There were significantly fewer referrals (20% v 29%; odds ratio 0. 64; 95% confidence interval 0.41 to 0.99) and a significantly higher use of tranexamic acid (odds ratio 2.38; 1.61 to 3.49) in the intervention group but no overall difference in norethisterone treatment compared with controls. There were more referrals when tranexamic acid was given with norethisterone than when it was given alone. Those practices reporting fewer than 10 cases showed the highest increase in prescribing of tranexamic acid. CONCLUSIONS: The educational package positively influenced referral for menorrhagia and treatment with appropriate non-hormonal drugs.  (+info)

Pharmacokinetics of epsilon-aminocaproic acid in patients undergoing aortocoronary bypass surgery. (5/402)

BACKGROUND: Epsilon-aminocaproic acid (EACA) is commonly infused during cardiac surgery using empiric dosing schemes. The authors developed a pharmacokinetic model for EACA elimination in surgical patients, tested whether adjustments for cardiopulmonary bypass (CPB) would improve the model, and then used the model to develop an EACA dosing schedule that would yield nearly constant EACA blood concentrations. METHODS: Consenting patients undergoing elective coronary artery surgery received one of two loading doses of EACA, 30 mg/kg (group I, n = 7) or 100 mg/kg (group II, n = 6) after CPB, or (group III) a 100 mg/kg loading dose before CPB and a 10 mg x kg(-1) x h(-1) maintenance infusion continued for 4 h during and after CPB (n = 7). Two patients with renal failure received EACA in the manner of group III. Blood concentrations of EACA, measured by high-performance liquid chromatography, were subjected to mixed-effects pharmacokinetic modeling. RESULTS: The EACA concentration data were best fit by a model with two compartments and corrections for CPB. The elimination rate constant k10 fell from 0.011 before CPB to 0.0006 during CPB, returning to 0.011 after CPB. V1 increased 3.8 l with CPB and remained at that value thereafter. Cl1 varied from 0.08 l/min before CPB to 0.007 l/min during CPB and 0.13 l/min after CPB. Cl2 increased from 0.09 l/min before CPB to 0.14 l/min during and after CPB. Two patients with renal failure demonstrated markedly reduced clearance. Using their model, the authors predict that an EACA loading infusion of 50 mg/kg given over 20 min and a maintenance infusion of 25 mg x kg(-1) x h(-1) would maintain a nearly constant target concentration of 260 microg/ml. CONCLUSIONS: EACA clearance declines and volume of distribution increases during CPB. The authors' model predicts that more stable perioperative EACA concentrations would be obtained with a smaller loading dose (50 mg/kg given over 20 min) and a more rapid maintenance infusion (25 mg x kg(-1) x h(-1)) than are typically employed.  (+info)

The effect of prophylactic epsilon-aminocaproic acid on bleeding, transfusions, platelet function, and fibrinolysis during coronary artery bypass grafting. (6/402)

BACKGROUND: Antifibrinolytic medications administered before skin incision decrease bleeding after cardiac surgery. Numerous case reports indicate thrombus formation with administration of epsilon-aminocaproic acid (epsilon-ACA). The purpose of this study was to examine the efficacy of epsilon-ACA administered after heparinization but before cardiopulmonary bypass in reducing bleeding and transfusion requirements after primary coronary artery bypass surgery. METHODS: Seventy-four adult patients undergoing primary coronary artery bypass surgery were randomized to receive 125 mg/kg epsilon-ACA followed by an infusion of 12.5 mg x kg(-1) x h(-1) or an equivalent volume of saline. Coagulation studies, thromboelastography, and platelet aggregation tests were performed preoperatively, after bypass, and on the first postoperative day. Mediastinal drainage was recorded during the 24 h after surgery. Homologous blood transfusion triggers were predefined and transfusion amounts were recorded. RESULTS: One patient was excluded for surgical bleeding and five patients were excluded for transfusion against predefined criteria One patient died from a dysrhythmia 2 h postoperatively. Among the remaining 67, the epsilon-ACA group had less mediastinal blood loss during the 24 h after surgery, 529+/-241 ml versus 691+/-286 ml (mean +/- SD), P < 0.05, despite longer cardiopulmonary bypass times and lower platelet counts, P < 0.05. Platelet aggregation was reduced in both groups following cardiopulmonary bypass but did not differ between groups. Homologous blood transfusion was similar between both groups. CONCLUSIONS: Prophylactic administration of epsilon-ACA after heparinization but before cardiopulmonary bypass is of minimal benefit for reducing blood loss postoperatively in patients undergoing primary coronary artery bypass grafting.  (+info)

The effects of hydrostatic pressure on the conformation of plasminogen. (7/402)

Plasminogen undergoes a large conformational change when it binds 6-aminohexanoate. Using ultraviolet absorption spectroscopy and native PAGE, we show that hydrostatic pressure brings about the same conformational change. The volume change for this conformational change is -33 mL.mol-1. Binding of ligand and hydrostatic pressure both cause the protein to open up to expose surfaces that had previously been buried in the interior.  (+info)

Relationship of TIMI myocardial perfusion grade to mortality after administration of thrombolytic drugs. (8/402)

BACKGROUND: Although improved epicardial blood flow (as assessed with either TIMI flow grades or TIMI frame count) has been related to reduced mortality after administration of thrombolytic drugs, the relationship of myocardial perfusion (as assessed on the coronary arteriogram) to mortality has not been examined. METHODS AND RESULTS: A new, simple angiographic method, the TIMI myocardial perfusion (TMP) grade, was used to assess the filling and clearance of contrast in the myocardium in 762 patients in the TIMI (Thrombolysis In Myocardial Infarction) 10B trial, and its relationship to mortality was examined. TMP grade 0 was defined as no apparent tissue-level perfusion (no ground-glass appearance of blush or opacification of the myocardium) in the distribution of the culprit artery; TMP grade 1 indicates presence of myocardial blush but no clearance from the microvasculature (blush or a stain was present on the next injection); TMP grade 2 blush clears slowly (blush is strongly persistent and diminishes minimally or not at all during 3 cardiac cycles of the washout phase); and TMP grade 3 indicates that blush begins to clear during washout (blush is minimally persistent after 3 cardiac cycles of washout). There was a mortality gradient across the TMP grades, with mortality lowest in those patients with TMP grade 3 (2.0%), intermediate in TMP grade 2 (4.4%), and highest in TMP grades 0 and 1 (6.0%; 3-way P=0.05). Even among patients with TIMI grade 3 flow in the epicardial artery, the TMP grades allowed further risk stratification of 30-day mortality: 0.73% for TMP grade 3; 2.9% for TMP grade 2; 5.0% for TMP grade 0 or 1 (P=0.03 for TMP grade 3 versus grades 0, 1, and 2; 3-way P=0.066). TMP grade 3 flow was a multivariate correlate of 30-day mortality (OR 0.35, 95% CI 0.12 to 1.02, P=0.054) in a multivariate model that adjusted for the presence of TIMI 3 flow (P=NS), the corrected TIMI frame count (OR 1.02, P=0.06), the presence of an anterior myocardial infarction (OR 2.3, P=0.03), pulse rate on admission (P=NS), female sex (P=NS), and age (OR 1.1, P<0.001). CONCLUSIONS: Impaired perfusion of the myocardium on coronary arteriography by use of the TMP grade is related to a higher risk of mortality after administration of thrombolytic drugs that is independent of flow in the epicardial artery. Patients with both normal epicardial flow (TIMI grade 3 flow) and normal tissue level perfusion (TMP grade 3) have an extremely low risk of mortality.  (+info)

Inclusion Criteria:. All trauma patients with ongoing significant haemorrhage (systolic blood pressure less than 90 mmHg and/or heart rate more than 110 beats per minute), or 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. Although entry is allowed up to 8 hours from injury, the earlier that patients can be treated the better.. Exclusion Criteria:. The fundamental eligibility criterion is the responsible doctors uncertainty as to whether or not to use an antifibrinolytic agent in a particular adult with traumatic haemorrhage. Patients for whom the responsible doctor considers there is a clear indication for antifibrinolytic therapy should not be randomised. Likewise, patients for whom there is considered to be a clear contraindication to antifibrinolytic therapy (such as, perhaps, those who have clinical evidence of a thrombotic disseminated intravascular coagulation) ...

AU - Stokes, Barrie J.. AU - Fergusson, Dean A.. AU - Ker, Katharine. PY - 2011/3/16. Y1 - 2011/3/16. N2 - Concerns regarding the safety of transfused blood have led to the development of a range of interventions to minimise blood loss during major surgery. Anti-fibrinolytic drugs are widely used, particularly in cardiac surgery, and previous reviews have found them to be effective in reducing blood loss, the need for transfusion, and the need for re-operation due to continued or recurrent bleeding. In the last few years questions have been raised regarding the comparative performance of the drugs. The safety of the most popular agent, aprotinin, has been challenged, and it was withdrawn from world markets in May 2008 because of concerns that it increased the risk of cardiovascular complications and death. To ...
A subarachnoid haemorrhage (SAH) is a bleed into the small space between the brain and skull that contains blood vessels that supply the brain (the subarachnoid space). The cause of a bleeding here is usually a rupture of a weak spot in one of these vessels. A SAH is a relatively uncommon type of stroke, but it often occurs at a young age (half the patients are younger than 50 years). The outcome of SAH is often poor: one-third of people die after the haemorrhage and of those who survive, one-fifth will require help for everyday activities. An important cause of poor recovery after SAH is a second bleed from the weakened vessel (rebleeding). This is thought to be caused by the dissolving of the blood clot at the original bleeding site that results from natural blood clot dissolving (fibrinolytic) activity. Antifibrinolytic therapy that reduces this activity was introduced as a treatment for reducing rebleeding and therefore for improving recovery after SAH. This review included 10 trials, ...
Hemorrhagic shock and death from exsanguination remain common following traumatic injury. Attaining rapid hemostasis through control of bleeding, correction of acidosis, prevention of hypothermia, and maximization of coagulation can decrease mortality. Hemostasis remains challenging secondary to coagulopathy from dysfunctional hyperfibrinolysis, which is observed following major trauma and physiologic stress. Hyperfibrinolysis leads to clot degradation and ongoing blood loss. Early administration of Antifibrinolytic agents such as Tranexamic Acid (TXA) can reduce mortality in patients with traumatic hemorrhage.

Patients with OSAS have an increased cardiovascular risk. This may be due to several pathophysiological mechanisms, one of which is a hypercoagulable state. PAI-1 has a well-known antifibrinolytic role. High levels of this molecule have been associated with cardiovascular disease,27 and it could be responsible for the increased cardiovascular risk in OSAS.. Several studies have reported higher PAI-1 levels in subjects with OSAS compared with healthy subjects.11-15 However, in the literature, contrasting results can be found on the relationship between levels of PAI-1 and AHI, the index of the severity of OSAS. von Känel et al13 showed a positive correlation, whereas Zamarrón et al25 found an inverse correlation.. In our subjects with OSAS, we observed higher PAI-1 levels than in the control subjects. Moreover, we have shown a significant positive correlation between PAI-1 and the severity of OSAS, as measured by AHI, time ,90%, and ODI.. In the subjects with OSAS, endothelial cells are exposed ...
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 ...
Emergency or urgent surgery, which can be defined as surgery which must be done promptly to save life, limb, or functional capacity, is associated with a high risk of bleeding and death. Antifibrinolytic drugs, such as tranexamic acid, promote blood clotting by preventing blood clots from breaking down. Previous studies have shown that this drug reduces the need for blood transfusion in patients undergoing elective surgery. The authors of this review searched for randomised controlled trials assessing the effects of tranexamic acid in patients undergoing urgent or emergency surgery. The results of this review show that tranexamic acid reduces the probability that a patient will receive a blood transfusion by around 30%. The effect of tranexamic acid on other important outcomes, such as death, remains uncertain. The authors conclude that larger studies should be done to assess the effects of tranexamic acid on relevant outcomes such as death in patients undergoing all types of emergency and ...

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.. Pack Size: Tranexamic Acid Injection is available in 5ml.. Minimum Order Quantity: 3000 ...
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 ...
Severe haemorrhage is a leading cause of maternal death worldwide. Most haemorrhage deaths occur soon after childbirth. Severe post-partum bleeding is sometimes managed by the surgical removal of the uterus (hysterectomy). Death and hysterectomy are important health consequences of post-partum haemorrhage, and clinical trials of interventions aimed at preventing these outcomes are needed. The World Maternal Antifibrinolytic trial aims to determine the effect of tranexamic acid on death, hysterectomy and other health outcomes in women with post-partum haemorrhage. It is an international, multicentre, randomised trial. Approximately 20,000 women with post-partum haemorrhage will be randomly allocated to receive an intravenous injection of either tranexamic acid or matching placebo in addition to usual care. The primary outcome measure is a composite of death in hospital or hysterectomy within 42 days of delivery. The cause of death will be described. Secondary outcomes include death, death due to bleeding

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 ...
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 ...
Aprotinin has been shown to be effective in reducing peri-operative blood loss and the need for re-operation due to continued bleeding in cardiac surgery. The lysine analogues tranexamic acid (TXA) and epsilon aminocaproic acid (EACA) are cheaper, but it is not known if they are as effective as aprotinin. Studies were identified by searching electronic databases and bibliographies of published articles. Data from head-to-head trials were pooled using a conventional (Cochrane) meta-analytic approach and a Bayesian approach which estimated the posterior probability of TXA and EACA being equivalent to aprotinin; we used as a non-inferiority boundary a 20% increase in the rates of transfusion or re-operation because of bleeding. Peri-operative blood loss was significantly greater with TXA and EACA than with aprotinin: weighted mean differences were 106 mls (95% CI 37 to 227 mls) and 185 mls (95% CI 134 to 235 mls) respectively. The pooled relative risks (RR) of receiving an allogeneic red blood cell (RBC)

In severe post-partum haemorrhage, death can occur within hours of bleeding onset so interventions to control the bleeding must be given immediately. In clinical trials of treatments for life-threatening bleeding, established treatments are given priority and the trial treatment is usually given last. However, enrolling patients in whom severe maternal morbidity or death is imminent or inevitable at the time of randomisation may dilute the effects of a trial treatment. We conducted an exploratory analysis of data from the WOMAN trial, an international, randomised placebo-controlled trial of the effects of tranexamic acid on death and surgical intervention in 20,060 women with post-partum haemorrhage. We assessed the impact of early maternal death or hysterectomy due to exsanguination on the effect of tranexamic acid on each of these respective outcomes. We conducted repeated analyses excluding patients with these outcomes at increasing intervals from the time of randomisation. We quantified treatment

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 ...
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.
Plasmin is the effector protease of the fibrinolytic system, well known for its involvement in fibrin degradation and clot removal. However, plasmin is also recognized as a potent modulator of immunological processes by directly interacting with various cell types including leukocytes (monocytes, macrophages, and dendritic cells) and cells of the vasculature (endothelial cells, smooth muscle cells) as well as soluble factors of the immune system and components of the extracellular matrix. In fact, the removal of misfolded proteins and maintenance of tissue homeostasis seem to be major physiological functions of plasmin. However, a large body of evidence also suggests that excessive plasmin generation frequently contributes to the pathophysiology of acute and chronic inflammatory processes. Hence, one question arising from the broadening effects of plasmin in physiology is whether antifibrinolytic drugs (i.e., tranexamic acid, epsilon aminocaproic acid, or aprotinin) that target plasmin either directly
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 recombinant mature AcSecapin-1 peptide was expressed in baculovirus-infected insect cells. AcSecapin-1 functions as a serine protease inhibitor-like peptide that has inhibitory effects against plasmin, elastases, microbial serine proteases, trypsin, and chymotrypsin. Consistent with these functions, AcSecapin-1 inhibited the plasmin-mediated degradation of fibrin to fibrin degradation products, thus indicating the role of AcSecapin-1 as an anti-fibrinolytic agent. AcSecapin-1 also inhibited both human neutrophil and porcine pancreatic elastases. Furthermore, AcSecapin-1 bound to bacterial and fungal surfaces and exhibited anti-microbial activity against fungi and gram-positive and gram-negative bacteria ...

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, ...

Background: 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods: This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. Findings: Between April 1, ...

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
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],

A major challenge remains the early management of immediate catastrophic bleeding in severe pelvic injuries. Standard treatment involves instituting pelvic mechanical stability as soon as possible to reduce pelvic volume and facilitate stable clot formation11. Immediate transfer to a specialist centre should be arranged ideally within 24 hours of the injury. Definitive fixation of pelvic injuries should then occur within 72 hours of the injury. Recent developments in resuscitation include the use of the antifibrinolytic agent tranexamic acid, rapid computed tomography (CT) in the emergency department to identify sources of bleeding and early blood transfusion (as opposed to fluid resuscitation) via massive transfusion protocols12. Further management for patients who fail to respond to temporary mechanical stabilisation of the pelvis and resuscitation include angiographic embolization or surgical pelvic packing via a laparotomy13,14. The exact role for each of these techniques remains undefined, ...
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.
