Thromb J 2022; 20:79. [PMID: 36529753 PMCID: PMC9762012 DOI: 10.1186/s12959-022-00440-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Accepted: 12/05/2022] [Indexed: 12/23/2022] Open
Abstract
OBJECTIVE Tranexamic acid (TXA) plays a significant role in the treatment of traumatic diseases. However, its effectiveness in patients with traumatic brain injury (TBI) seems to be contradictory, according to the recent publication of several meta-analyses. We aimed to determine the efficacy of TXA treatment at different times and doses for TBI treatment. METHODS PubMed, MEDLINE, EMBASE, Cochrane Library, and Google Scholar were searched for randomized controlled trials that compared TXA and a placebo in adults and adolescents (≥ 15 years of age) with TBI up to January 31, 2022. Two authors independently abstracted the data and assessed the quality of evidence. RESULTS Of the identified 673 studies, 13 involving 18,675 patients met our inclusion criteria. TXA had no effect on mortality (risk ratio (RR) 0.99; 95% confidence interval (CI) 0.92-1.06), adverse events (RR 0.93, 95% Cl 0.76-1.14), severe TBI (Glasgow Coma Scale score from 3 to 8) (RR 0.99, 95% Cl 0.94-1.05), unfavorable Glasgow Outcome Scale (GOS < 4) (RR 0.96, 95% Cl 0.82-1.11), neurosurgical intervention (RR 1.11, 95% Cl 0.89-1.38), or rebleeding (RR 0.97, 95% Cl 0.82-1.16). TXA might reduce the mean hemorrhage volume on subsequent imaging (standardized mean difference, -0.35; 95% CI [-0.62, -0.08]). CONCLUSION TXA at different times and doses was associated with reduced mean bleeding but not with mortality, adverse events, neurosurgical intervention, and rebleeding. More research data is needed on different detection indexes and levels of TXA in patients with TBI, as compared to those not receiving TXA; although the prognostic outcome for all harm outcomes was not affected, the potential for harm was not ruled out. TRIAL REGISTRATION The review protocol was registered in the PROSPERO International Prospective Register of Systematic Reviews (CRD42022300484).

Safety of antifibrinolytics in 6583 pediatric patients having craniosynostosis surgery: A decade of data reported from the multicenter Pediatric Craniofacial Collaborative Group. Paediatr Anaesth 2022; 32:1339-1346. [PMID: 35925835 DOI: 10.1111/pan.14540] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Revised: 07/17/2022] [Accepted: 07/21/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Antifibrinolytics such as tranexamic acid and epsilon-aminocaproic acid are effective at reducing blood loss and transfusion in pediatric patients having craniofacial surgery. The Pediatric Craniofacial Collaborative Group has previously reported low rates of seizures and thromboembolic events (equal to no antifibrinolytic given) in open craniofacial surgery. AIMS To query the Pediatric Craniofacial Collaborative Group database to provide an updated antifibrinolytic safety profile in children given that antifibrinolytics have become recommended standard of care in this surgical population. Additionally, we include the population of younger infants having minimally invasive procedures. METHODS Patients in the Pediatric Craniofacial Collaborative Group registry between June 2012 and March 2021 having open craniofacial surgery (fronto-orbital advancement, mid and posterior vault, total cranial vault remodeling, intracranial LeFort III monobloc), endoscopic cranial suture release, and spring mediated cranioplasty were included. The primary outcome is the rate of postoperative complications possibly attributable to antifibrinolytic use (seizures, seizure-like activity, and thromboembolic events) in infants and children undergoing craniosynostosis surgery who did or did not receive antifibrinolytics. RESULTS Forty-five institutions reporting 6583 patients were included. The overall seizure rate was 0.24% (95% CI: 0.14, 0.39%), with 0.20% in the no Antifibrinolytic group and 0.26% in the combined Antifibrinolytic group, with no statistically reported difference. Comparing seizure rates between tranexamic acid (0.22%) and epsilon-aminocaproic acid (0.44%), there was no statistically significant difference (odds ratio = 2.0; 95% CI: 0.6, 6.7; p = .257). Seizure rate was higher in patients greater than 6 months (0.30% vs. 0.18%; p = .327), patients undergoing open procedures (0.30% vs. 0.06%; p = .141), and syndromic patients (0.70% vs. 0.19%; p = .009). CONCLUSIONS This multicenter international experience of pediatric craniofacial surgery reports no increase in seizures or thromboembolic events in those that received antifibrinolytics (tranexamic acid and epsilon-aminocaproic acid) versus those that did not. This report provides further evidence of antifibrinolytic safety. We recommend following pharmacokinetic-based dosing guidelines for administration.

Prophylactic Use of Antifibrinolytics During Pediatric Cardiac Surgery With Cardiopulmonary Bypass on Postoperative Bleeding and Transfusion: A Systematic Review and Meta-Analysis. Pediatr Crit Care Med 2022; 23:e517-e529. [PMID: 35997516 DOI: 10.1097/pcc.0000000000003049] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/04/2023]
Abstract
OBJECTIVES To determine the effect of intraoperative antifibrinolytics, including tranexamic acid (TXA), aminocaproic acid (EACA), or aprotinin, on bleeding in children undergoing cardiac surgery with cardiopulmonary bypass (CPB). DATA SOURCES Relevant articles were systematically searched from Ovid MEDLINE, Ovid EMBASE, CINAHL, Cochrane Library, and Web of Science to November 15, 2021. STUDY SELECTION Abstracts were screened, and full texts were reviewed using predetermined inclusion and exclusion criteria using the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline. DATA EXTRACTION A standardized data extraction tool was used. DATA SYNTHESIS Sixty-eight studies including 28,735 patients were analyzed. TXA compared with placebo resulted in a mean decrease in chest tube output of 9.1 mL/kg (95% CI, 6.0-12.3 mL/kg), I2 equals to 65.2%, p value of less than 0.001, platelet requirement of 2.9 mL/kg (95% CI, 0.1-5.8 mL/kg), I2 =72.5%, p value less than 0.001 and plasma requirement of 4.0 mL/kg (95% CI, 0.6-7.2 mL/kg), I2 equals to 94.5%, p value less than0.001. Aprotinin compared with placebo resulted in a mean decrease in chest tube output of 4.3 mL/kg (2.4-6.2 mL/kg), I2 equals to 66.3%, p value of less than 0.001, platelet transfusion of 4.6 mL/kg (95% CI, 0.6-8.6 mL/kg), I2 equals to 93.6%, p value of less than 0.001, and plasma transfusion of 7.7 mL/kg (95% CI, 2.1-13.2 mL/kg), I2 equals to 95.3%, p value of less than 0.001. EACA compared with placebo resulted in a mean decrease in chest tube output of 9.2 mL/kg (2.3-21.0 mL/kg), I2 equals to 96.4%, p value of less than 0.001, RBC transfusion of 7.2 mL/kg (95% CI, 2.4-12.1 mL/kg), I2 equals to 94.5%, p value equals to 0.002, and platelet transfusion of 10.7 mL/kg (95% CI, 2.9-18.5 mL/kg), I2 equals to 0%, p value of less than 0.001. No statistical difference was observed in chest tube output when TXA was compared with aprotinin. Subgroup analysis of cyanotic patients showed a significant decrease in chest tube output, platelet requirement, and plasma requirement for patients receiving aprotinin. Overall, the quality of evidence was moderate. CONCLUSIONS Antifibrinolytics are effective at decreasing blood loss and blood product requirement in children undergoing cardiac surgery with CPB although the quality of evidence is only moderate.

Abstract
Background To compare the safety and efficacy of tranexamic acid (TXA)-soaked absorbable Gelfoam and the retrograde injection of TXA through a drain with drain-clamping in degenerative cervical laminoplasty patients. Methods Patients were assigned into either TXA retrograde injection (TXA-RI), TXA-soaked absorbable Gelfoam (TXA-Gel), or control groups. The demographics, operative measurements, volume and length of drainage, length of hospital stay, complete blood cell count, coagulopathy, postoperative complications, and blood transfusion were recorded. Results We enrolled 133 patients, with 44, 44, and 45 in the TXA-RI, TXA-Gel, and control groups, respectively. The baseline characteristics did not differ significantly among the three groups. The TXA-RI group exhibited a lower volume and length of postoperative drainage compared to the TXA-Gel and control groups (126.60 ± 31.27 vs. 156.60 ± 38.63 and 275.45 ± 75.27 mL; 49.45 ± 9.70 vs 58.70 ± 10.46 and 89.31 ± 8.50 hours, all P < 0.01). The TXA-RI group also had significantly shorter hospital stays compared to the control group (5.31 ± 1.18 vs 7.50 ± 1.25 days, P < 0.05) and higher hemoglobin and hematocrit levels (12.58 ± 1.67 vs 11.28 ± 1.76 g/dL; 36.62 ± 3.66% vs 33.82 ± 3.57%, both P < 0.05) at hospital discharge. In the TXA-RI and TXA-Gel groups, the D-dimmer (DD) and fibrinogen (FIB) were significantly lower than those in the control group after surgery (P < 0.05). None of the patients required blood transfusion. No complications, including thromboembolic events, were reported. Conclusion Topical retrograde injection of TXA through a drain with drain-clamping at the conclusion of unilateral posterior cervical expansive open-door laminoplasty may effectively reduce postoperative blood loss and the length of hospital stays without increasing postoperative complications.

Post-operative tranexamic acid decreases chest tube drainage following vertebral body tethering surgery for scoliosis correction. Spine Deform 2022; 10:811-816. [PMID: 35262880 DOI: 10.1007/s43390-022-00492-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Accepted: 02/19/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE Anterior vertebral body tethering (VBT) is a non-fusion surgical treatment for Adolescent Idiopathic Scoliosis requiring chest tube(s) (CT). We sought to assess the efficacy of post-op intravenous tranexamic acid (IV TXA) in reducing CT drainage and retention. METHODS 35 VBT patients received 24 h of post-op IV TXA (2 mg/kg/h) were compared to 49 who did not. Group comparisons were performed using Wilcoxon rank-sum and chi-squared tests. Multivariate linear regression analysis was used to assess the relationships between TXA and both CT drainage and retention time. RESULTS There were no group differences at baseline (Table). CTs placed for thoracic (T) and thoracolumbar (TL) curves were assessed separately. For TH CT, there was less total CT drainage in the TXA group (TXA 569.4 ± 337.4 mL vs. Non-TXA 782.5 ± 338.9 mL; p = 0.003) and shorter CT retention time (TXA 3.0 ± 1.3 vs. Non-TXA 3.9 ± 1.4 days; p = 0.003). For TL CT, there was less total CT drainage in the TXA group (TXA 206.8 ± 152.2 mL vs. Non-TXA 395.7 ± 196.1 mL; p = 0.003) and shorter CT retention time (TXA 1.7 ± 1.3 vs. Non-TXA 2.7 ± 1.0 days; p = 0.001). Following multivariate analysis, use of TXA was the only significant predictor of both drainage in T and TL CTs (p = 0.012 and p = 0.002, respectively) as well as T and TL CT retention time (p = 0.008 and p = 0.009, respectively). There were no differences in LOS (p = 0.863) or ICU stay (p = 0.290). CONCLUSION IV TXA results in a significant decrease in CT drainage and retention time. CT retention is decreased by 1 day for those that receive TXA. LEVEL OF EVIDENCE III.

Abstract
Craniosynostosis, the premature fusion of skull sutures in children, requires surgical correction. This procedure routinely requires allogeneic blood transfusions, which are associated with multiple risks of their own. Since 2008, antifibrinolytics tranexamic acid (TXA) and epsilon aminocaproic acid (EACA or Amicar) have been widely used. There is literature comparing the two agents in scoliosis and cardiothoracic surgery, but the literature comparing the two agents in pediatric craniofacial surgery (CF) is limited. Tranexamic acid use is more common in pediatric CF surgery and has been thoroughly studied; however, it costs about three times as much as EACA and has been associated with seizures. This study compiles the literature assessing the safety and efficacy of EACA in reducing blood loss and transfusion volumes in children and explores its potential use in pediatric CF surgery. Papers from 2000 to 2021 regarding the effectiveness and safety of EACA in Pediatric scoliosis, cardiothoracic, and craniosynostosis surgery were reviewed and compiled. Papers were found via searching PubMed and Cochrane databases with the key terms: Epsilon aminocaproic acid, EACA, Amicar, Tranexamic acid, TXA, craniosynostosis, scoliosis, cardiothoracic, and pediatric. Prospective studies, retrospective studies, and meta-analyses were included. Twenty-nine papers were identified as pertinent from the literature searched. Four were meta-analyses, 14 were retrospective, and 11 were prospective. Of these papers, seven were of cardiac surgery, 12 were of scoliosis, and nine were of craniosynostosis. During our search, EACA has been shown to consistently reduce blood transfusion volumes compared to control. However, it is not as effective when compared to TXA. EACA has a similar safety profile to TXA but has a reduced risk of seizures. There are not many studies of EACA in craniosynostosis repair, but the existing literature shows promising results for EACA's efficacy and safety, warranting more studies.

Abstract
Children and adolescents undergoing posterior spinal fusion for scoliosis experience high rates of bleeding and blood product transfusion. Antifibrinolytic therapy is one key strategy to decrease blood loss and transfusion in pediatric scoliosis surgery. Here we review 172 pediatric scoliosis patients (birth to 21 y) who underwent posterior spinal fusion at our institution from 2017 to 2018. We reported rates of blood loss and transfusion, compared patients receiving tranexamic acid to a ε-aminocaproic acid, and evaluated antifibrinolytic agent and laboratory parameters as predictors of blood loss and transfusion. Intraoperatively, 62% received tranexamic acid and 38% received ε-aminocaproic acid. Overall, blood loss (mean intraoperative estimated blood loss=14.9±9.7 mL/kg, 22% with clinically significant blood loss [>20 mL/kg], and mean calculated hemoglobin mass loss=175.9±70.1 g) and transfusion rates (15% with intraoperative allogeneic red blood cell transfusion and mean intraoperative allogeneic red blood cell transfusion volume=12.5±7.1 mL/kg) were similar to previous cohorts studying intraoperative antifibrinolytics. There was no difference in intraoperative estimated blood loss, clinically significant blood loss, calculated hemoglobin mass loss, or transfusion rates between the antifibrinolytic groups. Antifibrinolytic choice was not predictive of blood loss or transfusion. Routine hematologic laboratory parameters and antifibrinolytic choice were insufficient to predict blood loss or other outcomes. Future prospective laboratory-based studies may provide a more comprehensive model of surgical-induced coagulopathy in scoliosis surgery and provide a better tool for predicting blood loss and improving outcomes.

Abstract
Tranexamic acid (TXA) is widely utilized to control perioperative bleeding. TXA is considered a safe drug with few serious adverse effects, but many studies report TXA-associated seizures especially with cardiac surgeries. Usually, TXA-associated seizures persist for few minutes with no progression into status epilepticus. Here, we report, for the first time, a case of refractory status epilepticus after IV injection of TXA in a pediatric non-cardiac surgery. This case report and literature review aim to increase awareness about TXA-associated seizures and to provide mechanistic-based prevention and treatment recommendations. During adenotonsillectomy for a 4-year-old male child, TXA infusion started after induction of anesthesia for surgical bleeding prophylaxis. During recovery from anesthesia, the patient developed tonic-clonic convulsions which did not improve after two IV doses of midazolam but showed an improvement after a dose of propofol. The patients did not regain consciousness and was transferred to the ICU. He had recurrent treatment-resistant attacks of tonic-clonic convulsions. The patient developed acute kidney injury and died after 18 hours. In high-risk patients, using the lowest effective dose with early termination of TXA infusion and prolongation of administration of anesthetics may prevent seizures. General anesthetics (propofol and halogenated inhaled anesthetics) are considered the first line for prevention/treatment of TXA-associated seizures.

Abstract
6-aminohexanoic acid is an ω-amino acid with a hydrophobic, flexible structure. Although the ω-amino acid in question is mainly used clinically as an antifibrinolytic drug, other applications are also interesting and important. This synthetic lysine derivative, without an α-amino group, plays a significant role in chemical synthesis of modified peptides and in the polyamide synthetic fibers (nylon) industry. It is also often used as a linker in various biologically active structures. This review concentrates on the role of 6-aminohexanoic acid in the structure of various molecules.

Abstract
BACKGROUND Bleeding is one of the commonest complications affecting children undergoing cardiac surgery on cardiopulmonary bypass. Antifibrinolytic drugs are part of a multifaceted approach aimed at reducing bleeding, though sufficiently sized pediatric studies are sparse, and dosing algorithms are heterogeneous. Our objective was to evaluate the efficacy and safety of antifibrinolytic agents as well as the effectiveness of different dosing regimens in pediatric cardiac surgery using cardiopulmonary bypass. METHODS We performed a systematic review and meta-analysis evaluating randomized controlled trials published between 1980 and 2019, identified by searching the databases MEDLINE, EMBASE, PubMed, and CENTRAL. All studies investigating patients <18 years of age without underlying hematological disorders were included. The primary outcome was postoperative bleeding; secondary end points included blood product transfusion, mortality, and safety (thromboses, anaphylaxis, renal or neurological dysfunction, and seizures). Different dosing regimens were compared. Studies were dual appraised, outcomes were reported descriptively and, if appropriate, quantitatively using the Review Manager 5 (REVMAN 5) software (The Cochrane Collaboration). RESULTS Thirty of 209 articles were included, evaluating the following drugs versus control: aprotinin n = 14, tranexamic acid (TXA) n = 12, and epsilon-aminocaproic acid (EACA) n = 4. The number of participants per intervention group ranged from 11 to 100 (median, 25; interquartile range [IQR], 20.5) with a wide age span (mean, 13 days to 5.8 years) and weight range (mean, 3.1-26.3 kg). Methodological quality was low to moderate.All agents reduced mean 24-hour blood loss compared to control: aprotinin by 6.0 mL/kg (95% confidence interval [CI], -9.1 to -3.0; P = .0001), TXA by 9.0 mL/kg (95% CI, -11.3 to -6.8; P < .00001), and EACA by 10.5 mL/kg (95% CI, -21.1 to 0.0; P = .05). Heterogeneity was low for TXA (I2 = 29%; P = .19), moderate for aprotinin (I2 = 41%; P = .11), and high for EACA (I2 = 95%; P = <.00001). All agents also reduced 24-hour blood product transfusion. There was no clear dose-response effect for TXA nor aprotinin. Studies were underpowered to detect significant differences in mortality, thromboses, anaphylaxis, and renal or neurological dysfunction. CONCLUSIONS The available data demonstrate efficacy for all 3 antifibrinolytic drugs. Therefore, the agent with the most favorable safety profile should be used. As sufficient data are lacking, large comparative trials are warranted to assess the relative safety and appropriate dosing regimens in pediatrics.

Abstract
BACKGROUND Previous studies have demonstrated that the use of tranexamic acid (TXA) reduces blood loss and transfusion requirements in children undergoing scoliosis surgery. Although TXA is safe and effective, significant adverse events have been reported. Using the lowest effective dose of TXA is advisable. We evaluated a new low dosing regimen for TXA based on an improved pharmacokinetic model and therapeutic plasma concentration. The purpose of this study is to evaluate the effectiveness of this new low dosing regimen in reducing blood loss and transfusion requirements in patients with adolescent idiopathic scoliosis undergoing posterior spinal fusion when compared with a control group who did not receive TXA. METHODS We retrospectively reviewed 90 consecutive patients with idiopathic scoliosis undergoing posterior spinal fusion at our institution from 2017 to 2020. Forty patients received TXA at the new dosing regimen (10 mg/kg load, 5 mg/kg/h infusion) and 50 patients were in the non-TXA control group. The same 2 orthopaedic surgeons, working as a team, performed all surgical procedures. We assessed the use of TXA as an independent risk factor for estimated blood loss and transfusion requirement after adjusting for age, surgical duration, body mass index, major coronal curve, and sex. RESULTS A comparison of the intraoperative cumulative blood loss in the 2 groups showed a significantly lower blood loss in the TXA group. (583.5±272.0 vs. 479.5±288.7 mL, P=0.03) This difference persisted when blood loss was calculated as percent of total blood volume and per vertebral level. Transfusion requirements were lower in the TXA group (4/50 patients vs. 0/40 patients, P=0.13). No patient in the TXA group required a blood transfusion during their hospitalization. CONCLUSION This study is the first to provide evidence that a new low dosing regimen of TXA can significantly reduce blood loss and transfusion requirements for idiopathic scoliosis patients and supports the need for a prospective, randomized clinical trial to confirm these findings.

Abstract
Antifibrinolytic drugs are used to reduce blood loss and subsequent transfusions during surgery and following trauma, but the optimal dosing regimen in the pediatric population is still unresolved. The aim of this systematic review was to evaluate efficacy and safety of antifibrinolytic drugs in pediatric surgery and trauma to determine the optimal dosing regimen. A literature search was performed in PubMed, Embase, Cochrane, and Web of Science on May 3, 2020. We included randomized controlled studies investigating the effect of tranexamic acid (TXA), aprotinin, and epsilon-aminocaproic acid, in terms of reducing blood loss, blood transfusions, reoperations, and rebleeds in pediatric patients aged 0 to 18 years undergoing cardiac surgery, noncardiac surgery, or trauma. Fifty randomized controlled trials (RCTs) were included; 28 RCTs investigated cardiac surgery and 22 investigated noncardiac surgery. No RCTs regarding trauma met the inclusion criteria. All antifibrinolytic drugs reduced postoperative blood loss and transfusions when used in pediatric surgery. The dosing regimen varied between studies, but similar effect sizes were found in terms of reduced blood loss regardless of the cumulative dose used. Few studies found adverse events, and no difference in incidence or type of adverse events was seen between the antifibrinolytic and the placebo group. In conclusion, use of antifibrinolytics is efficient and safe in children undergoing surgery. We propose TXA as the drug of choice based on its level of evidence and safety profile; we recommend a dosing regimen composed of a loading dose of 10 to 15 mg/kg prior to surgery followed by 1 to 5 mg/kg/h as continuous infusion throughout surgery.

A systematic review and meta-analysis. J Clin Orthop Trauma 2021; 20:101488. [PMID: 34277342 PMCID: PMC8267494 DOI: 10.1016/j.jcot.2021.101488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 06/23/2021] [Accepted: 06/27/2021] [Indexed: 10/21/2022] Open
Abstract
BACKGROUND Cerebral palsy (CP) children undergoing hip reconstruction are more prone to blood loss during surgery due to poor nutritional status, antiepileptic medication intake, depletion of clotting factors, and the extent of surgery involved. We conducted this present review to analyze whether antifibrinolytics during hip surgery in CP children would reduce surgical blood loss and transfusion requirements. METHODS Three databases (PubMed, EMBASE, and Cochrane library) were searched independently for publications mentioning the use of antifibrinolytics during hip reconstruction surgery in CP children. The primary outcome was to compare the surgical blood loss with and without antifibrinolytics use. Secondary outcomes were transfusion requirements, drop in hemoglobin level, length of hospital stay, and complication rates. RESULTS All five studies (reporting 478 patients) published on this topic were found eligible based on inclusion criteria and were included for final analysis. Primary outcome: In three of the included studies, antifibrinolytics use resulted in a significant reduction in total blood loss with a mean difference (MD) of -151.05 mL (95% CI -272.30 to -29.80, p = 0.01). In the other two studies although statistically not significant, antifibrinolytics use reduces estimated blood loss (MD: 3.27, 95% CI -21.44 to 14.91, p = 0.72). Secondary outcomes: We observed that in the antifibrinolytics group, there was a reduction in total blood transfusion requirements (OD: 0.70, 95% CI 0.35 to 1.37, p = 0.29), and a drop in haemoglobin level (MD: 0.16, 95% CI -0.62 to 0.30, p = 0.49) but statistically not significant. No adverse effects related directly to antifibrinolytics were noticed in all five studies. CONCLUSION Only two out of five included studies favored the use of antifibrinolytics in CP children undergoing hip reconstruction. The evidence synthesized on this meta-analysis is also not sufficient enough to support its routine use in this cohort of children for hip reconstruction surgery. High-quality studies with adequate sample size to determine the effective and safe dosage, timing, and cost involved of different antifibrinolytics are the need of the hour. LEVEL OF EVIDENCE Ⅲ.

Abstract
OBJECTIVES The current study aimed to compare the benefits of topical and low-dose systemic tranexamic acid administration in pediatric cardiac surgery. METHODS A total of 117 children undergoing cardiac surgery for congenital heart disease were assigned into three groups. Patients in the systemic group received 20 mg/kg-1 tranexamic acid through the cardiopulmonary bypass followed by another dose of 20 mg/kg-1 after cardiopulmonary bypass separation. Patients in the topical group were administered with 50 mg/kg-1 tranexamic acid poured into the pericardium, while the control group received no antifibrinolytics. The outcome measures of bleeding and blood products transfusion were recorded over the first 48 h postoperatively. RESULTS Chest tube drainage was significantly lower in both topical and systemic groups than the control group, but it did not differ between the case groups. Blood products requirement did not show a difference between groups. Neurological or thromboembolic events did not variate among the groups, and no deaths occurred in this study. CONCLUSION Topical or systemic tranexamic acid administration reduced postoperative blood loss effectively without adding an extra risk.

Abstract
Objectives: To compare the effectiveness of epsilon aminocaproic acid (EACA) to tranexamic acid (TA) in reducing blood loss and transfusion requirements in patients undergone cardiac surgery under cardiopulmonary bypass. Design: Randomized, double blinded study. Outcome variables collected included; baseline demographic characteristics, type of surgery, amount of 24 hour chest tube drainage, amount of 24 hour blood products administered, 30 day mortality and morbidity and length of stay. We analyzed the data using parametric and non-parametric tests as appropriate. Setting: Single center tertiary-care university hospital setting. Participants: 114 patients who had undergone cardiac surgery under cardiopulmonary bypass. Interventions: Standard dose of intra-operative EACA or TA was compared in patients undergone cardiac surgery under cardiopulmonary bypass. Results: There was no statistically significant difference between groups when analyzing chest tube drainage. However, there was a significant difference in the administration of any transfusion (PRBC's, FFP, platelets) intra-operatively to 24 hours postoperatively, with less transfusion in patients receiving EACA compared to TA (25% vs. 44.8%, respectively P = 0.027). Additionally, there was no significant difference in terms of adverse events during the one month follow up period. Conclusion: The findings of this study suggest that EACA and TA have similar effects on chest tube drainage but EACA is associated with fewer transfusions in CABG alone surgeries. Our results suggest that EACA can be used in a similar fashion to TA which may result in a cost and morbidity advantage.

Abstract
BACKGROUND ε-Aminocaproic acid (EACA) is an antifibrinolytic agent that has been shown to decrease blood loss and transfusion requirements in several populations undergoing various surgical procedures. However, the efficacy of EACA has not been assessed in pediatric patients with cerebral palsy undergoing bilateral varus rotational femoral osteotomies. The purpose of this study was to assess the efficacy of intravenous EACA in reducing calculated intraoperative blood loss and transfusions in this population. METHODS Patients aged 18 years or younger were eligible. Patients were randomized to receive EACA or placebo (saline), and randomization was stratified based on sex and whether or not additional soft tissue or osseous procedures were performed. On the basis of retrospective data, the calculated sample size was 12 patients per arm to detect a difference of 250-mL blood loss. The primary outcome was calculated intraoperative blood loss. Secondary outcomes included transfusion requirements, 24-hour drain output, length of stay, and incidence of complications. RESULTS The mean age of patients in this study was 8 years (SD: 2.4 y). There were no differences in age, sex, height, weight, type of anesthesia, operative time, and associated procedures between the EACA and placebo groups (P>0.05). Preoperative hematocrit was lower in the EACA group (37.1 vs. 40.0, P=0.04). Calculated intraoperative blood loss was 536 mL in the EACA group and 628 mL in the placebo group (P=0.45). Transfusions were required in 62% of patients in the EACA group and 67% of patients in the placebo group (P=0.68). Total 24-hour drain output was 72.5 mL in the EACA group and 103.3 mL in the placebo group (P=0.37). Length of stay was similar between both groups, and there were no drug or placebo-related complications in either group. CONCLUSIONS There was no difference in blood loss or transfusion requirements associated with EACA compared with placebo; however, this study is underpowered to detect smaller differences in blood loss. Additional studies with larger sample sizes are needed to confirm these findings and further elucidate the indications for antifibrinolytic agents in pediatric patients. LEVEL OF EVIDENCE Level I.

Abstract
Tranexamic acid (TXA) is one of the measures indicated to reduce bleeding and the need for volume replacement. However, data on risks and benefits are controversial. This study analyzes the effectivity and risks of using tranexamic acid in neurosurgery. We selected articles, published from 1976 to 2019, on the PubMed, EMBASE, Science Direct, and The Cochrane Database using the descriptors: "tranexamic acid," "neurosurgery," "traumatic brain injury," "subdural hemorrhage," "brain aneurysm," and "subarachnoid hemorrhage." TXA can reduce blood loss and the need for blood transfusion in trauma and spinal surgery. Despite the benefits of TXA, moderate-to-high doses are potentially associated with neurological complications (seizures, transient ischemic attack, delirium) in adults and children. In a ruptured intracranial aneurysm, the use of TXA can considerably reduce the risk of rebleeding, but there is weak evidence regarding its influence on mortality reduction. The TXA use in brain surgery does not present benefit. However, this conclusion is limited because there are few studies. TXA in neurosurgeries is a promising method for the maintenance of hemostasis in affected patients, mainly in traumatic brain injury and spinal surgery; nevertheless, there is lack of evidence in brain and vascular surgeries. Many questions remain unanswered, such as how to determine the dosage that triggers the onset of associated complications, or how to adjust the dose for chronic kidney disease patients.

Abstract
OBJECTIVE Patients undergoing open cranial vault remodeling for craniosynostosis frequently experience substantial blood loss requiring blood transfusion. Multiple reports in the literature have evaluated the impact of individual blood conservation techniques on blood transfusion rates during craniosynostosis surgery. The authors engaged a multidisciplinary team and assessed the impact of input from multiple stakeholders on the evolution of a comprehensive quality improvement protocol aimed at reducing or eliminating blood transfusion in patients undergoing open surgery for craniosynostosis. METHODS Over a 4-year period from 2012 to 2016, 39 nonsyndromic patients were operated on by a single craniofacial plastic surgeon. Initially, no clear blood conservation protocol existed, and specific interventions were individually driven. In 2014, a new pediatric neurosurgeon joined the craniofacial team, and additional stakeholders in anesthesiology, transfusion medicine, critical care, and hematology were brought together to evaluate opportunities for developing a comprehensive blood conservation protocol. The initial version of the protocol involved the standardized administration of intraoperative aminocaproic acid (ACA) and the use of a cell saver. In the second version of the protocol, the team implemented the preoperative use of erythropoietin (EPO). In addition, intraoperative and postoperative resuscitation and transfusion guidelines were more clearly defined. The primary outcomes of estimated blood loss (EBL), transfusion rate, and intraoperative transfusion volume were analyzed. The secondary impact of multidisciplinary stakeholder input was inferred by trends in the data obtained with the implementation of the partial and full protocols. RESULTS Implementing the full quality improvement protocol resulted in a 66% transfusion-free rate at the time of discharge compared to 0% without any conservation protocol and 27% with the intermediate protocol. The administration of EPO significantly increased starting hemoglobin/hematocrit (11.1 g/dl/31.8% to 14.7 g/dl/45.6%, p < 0.05). The group of patients receiving ACA had lower intraoperative EBL than those not receiving ACA, and trends in the final-protocol cohort, which had received both preoperative EPO and intraoperative ACA, demonstrated decreasing transfusion volumes, though the decrease did not reach statistical significance. CONCLUSIONS Patients undergoing open calvarial vault remodeling procedures benefit from the input of a multidisciplinary stakeholder group in blood conservation protocols. Further research into comprehensive protocols for blood conservation may benefit from input from the full surgical team (plastic surgery, neurosurgery, anesthesiology) as well as additional pediatric subspecialty stakeholders including transfusion medicine, critical care, and hematology.

Abstract
Context Off-pump coronary artery bypass graft (CABG) surgeries have been shown to have increased fibrinolysis due to tissue plasminogen activator release. There are no trials comparing the two available antifibrinolytics (tranexemic acid and epsilon-amino-caproic acid) in off-pump CABG surgeries. Aims The aim of the present study was to compare the effectiveness of tranexamic acid and epsilon-amino-caproic acid with respect to postoperative bleeding at 4 and 24 hours as the primary outcome, and rate of postoperative transfusion, re-operations, complication rate, serum fibrinogen, and D-dimer levels as secondary outcomes. Settings and Design The study was carried out at a tertiary-level hospital between June 2017 and June 2018. It was a prospective, randomized, double-blind study. Materials and Methods Eighty patients undergoing off-pump CABG, were randomly allocated to receive tranexamic acid or epsilon-amino-caproic acid. The patients were followed up in the postoperative period and were assessed for primary and secondary outcomes. Statistical Analysis Used Statistical analysis was performed using SPSS software, version 19.0 (SPSS Inc., Chicago, IL). Nonparametric data were expressed as median with interquartile range and compared using Mann-Whitney U-test, parametric data was represented as mean with standard deviation and analyzed using Student's t-test. Nominal data were analyzed using Chi-square test. Results Bleeding at 4 hours did not show significant difference between groups, 180 ml (80-250) vs 200 ml (100-310). Bleeding at 24 hours was significantly lesser in tranexamic acid group as compared to epsilon-amino-caproic acid group, 350 ml (130-520) vs 430 ml (160-730) (P = 0.0022) The rate of transfusion, re-operations, seizures, renal dysfunction, fibrinogen levels, and D-dimer levels did not show significant difference between the groups. Conclusions Tranexamic acid significantly reduced postoperative bleeding in off-pump CABG at 24 hours as compared to epsilon-amino-caproic-acid.

Safety and efficacy of epsilon aminocaproic acid (EACA) as an antihemorrhagic drug in bilateral one stage total knee arthroplasty: A double-blind randomized controlled trial. Knee 2020; 27:229-234. [PMID: 31882387 DOI: 10.1016/j.knee.2019.09.019] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2018] [Revised: 07/05/2019] [Accepted: 09/25/2019] [Indexed: 02/05/2023]
Abstract
BACKGROUND Antifibrinolytic drugs are widely used to minimize blood loss and transfusion requirements in total knee arthroplasty (TKA). Although tranexamic acid (TXA) has been widely studied for its use in TKA, there are limited studies on epsilon-aminocaproic acid (EACA). METHODS In a double-blind randomized control trial, all patients (n = 91) operated with bilateral simultaneous TKA were randomly given either intravenous EACA or placebo (normal saline). A single surgeon performed the TKA with posterior-stabilized implants under tourniquet. A suction drain was placed and kept for 48 h postoperatively. The intraoperative blood loss and drain output were calculated. The postoperative hemoglobin (Hb), drop in Hb, total blood loss, and number of blood transfusions in each group were calculated. RESULTS Both of the groups were comparable in terms of age, sex, body mass index, and pre-operative Hb. There was a significant difference between the EACA group and control group in terms of intraoperative blood loss (150 ml vs. 165 ml, P = 0.01), drain output (494 ml vs. 1062 ml, P < 0.001), postoperative Hb (9.9 g/dl vs. 8.6 g/dl, P = 0.002), drop in Hb (2.2 g/dl vs. 3.1 g/dl, P = 0.026) and transfusion rate (median transfusion 0 vs. 1, P < 0.001). The total blood loss, as calculated by the Hb balance method, was significantly less (P < 0.001) in the EACA group (0.99 l) compared with the control group (2.71 l). None of the patients developed any adverse reaction/complication to the drug. CONCLUSION Intraoperative administration of EACA significantly decreased the blood loss and postoperative transfusion rates compared with no antifibrinolytic therapy in bilateral simultaneous TKA.

Abstract
INTRODUCTION An initial retrospective study suggested that tranexamic acid (TXA) administration increased the incidence of seizures in paediatric patients undergoing cardiac surgery. However, the efficacy of TXA in paediatric cardiac surgery remains unclear owing to the small sample sizes of the studies. Therefore, this study will investigate the efficacy and safety of TXA in paediatric patients undergoing cardiac surgery. We hypothesised that TXA may increase the incidence of postoperative seizures with no effect on postoperative allogeneic transfusion in paediatric patients undergoing cardiac surgery. The pragmatic study will provide important implications for paediatric cardiac surgery. METHODS AND ANALYSIS This will be a single-centre prospective, double-blind randomised controlled trial. The plan is to enrol in the study 2090 paediatric patients aged 31 days to 7 years who will be undergoing cardiac surgery with cardiopulmonary bypass (CPB). All eligible participants will be randomly assigned to either the TXA or placebo group by using a Web-based randomisation service in a 1:1 ratio. The primary safety end point will be postoperative seizures until hospital discharge, and the primary efficacy end point will be the volume of allogeneic red blood cell transfusion after termination of CPB. All patients will be followed up for 1 year postdischarge. All data will be analysed in accordance with the intention-to-treat principle. ETHICS AND DISSEMINATION This study was approved by the institutional review board of Fuwai Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College (No 20191195). Written informed consent will be obtained from the parents/legal guardian of each patient because all participants will be <18 years of age. The results of the trial will be published in an international peer-reviewed journal. TRIAL REGISTRATION NUMBER Chinese Clinical Trial Register (ChiCTR1900024131).

Tranexamic acid and perioperative bleeding in children: what do we still need to know? Curr Opin Anaesthesiol 2019; 32:343-352.

Abstract
PURPOSE OF REVIEW Perioperative bleeding and blood product transfusion are associated with significant morbidity and mortality. Prevention and optimal management of bleeding decreases risk and lowers costs. Tranexamic acid (TXA) is an antifibrinolytic agent that reduces bleeding and transfusion in a broad number of adult and pediatric surgeries, as well as in trauma and obstetrics. This review highlights the current pediatric indications and contraindications of TXA. The efficacy and safety profile, given current and evolving research, will be covered. RECENT FINDINGS Based on the published evidence, prophylactic or therapeutic TXA administration is a well-tolerated and effective strategy to reduce bleeding, decrease allogeneic blood product transfusion, and improve pediatric patients' outcomes. TXA is now recommended in recent guidelines as an important part of pediatric blood management protocols. SUMMARY Based on TXA pharmacokinetics, the authors recommend a dosing regimen of between 10 to 30 mg/kg loading dose followed by 5 to 10 mg/kg/h maintenance infusion rate for pediatric trauma and surgery. Maximal efficacy and minimal side-effects with this dosage regime will have to be determined in larger prospective trials including high-risk groups. Furthermore, future research should focus on determining the ideal TXA plasma therapeutic concentration for maximum efficacy and minimal side-effects.

Abstract
Efforts to reduce blood product transfusions and adopt blood conservation strategies for infants and children undergoing cardiac surgical procedures are ongoing. Children typically receive red blood cell and coagulant blood products perioperatively for many reasons, including developmental alterations of their hemostatic system, and hemodilution and hypothermia with cardiopulmonary bypass that incites inflammation and coagulopathy and requires systemic anticoagulation. The complexity of their surgical procedures, complex cardiopulmonary interactions, and risk for inadequate oxygen delivery and postoperative bleeding further contribute to blood product utilization in this vulnerable population. Despite these challenges, safe conservative blood management practices spanning the pre-, intra-, and postoperative periods are being developed and are associated with reduced blood product transfusions. This review summarizes the available evidence regarding anemia management and blood transfusion practices in the perioperative care of these critically ill children. The evidence suggests that adoption of a comprehensive blood management approach decreases blood transfusions, but the impact on clinical outcomes is less well studied and represents an area that deserves further investigation.

Abstract
Fibrinolytic activation is a major and preventable source of bleeding in neonates and children undergoing cardiac surgery with cardiopulmonary bypass. Based on the existing literature (adult and pediatric; cardiac and noncardiac), prophylactic administration of antifibrinolytic agents can help reduce fibrinolytic activation, and consequently reduces perioperative bleeding and the requirement for blood product transfusion. Due to the increased risk of renal failure and mortality reported in adults undergoing cardiac surgery, aprotinin should not be considered as a safe option in neonates and children. Further well-designed studies would be required before the prophylactic administration of aprotinin could be considered in pediatric cardiac surgery. The lysine analogs, tranexamic acid and ϵ-aminocaproic acid,, should be considered as safe and effective antifibrinolytic agents. Although no major side effects have been reported following the administration of lysine analogs in children undergoing cardiac surgery, high-dose tranexamic acid should not be recommended in order to avoid the increased risk of clinical seizures. Despite the recent advances made in our understanding of the pharmacokinetics of tranexamic acid and ϵ-aminocaproic acid,, the optimal plasmatic concentration to be targeted remains unknown. Further studies are therefore urgently needed to better define the optimal dose regimen to be used in neonates and children. In the meantime, the dose regimen published in the most recent pharmacokinetic studies can be used. Although no studies have assessed the effect of massive bleeding and transfusion on the plasmatic concentrations of the lysine analogs, additional boluses might be considered in the presence of bleeding and/or when signs of fibrinolytic activations are observed on viscoelastic hemostatic assays.

Abstract
Aims: This study evaluated the efficacy and safety of tranexamic acid (TXA) undergoing cardiac surgery. Methods: Using a retrospective cohort study design, 2,026 consecutive pediatric patients who underwent surgical repair of atrial or ventricular septal defect or complete repair of Tetralogy of Fallot were included, and divided into a control group and a TXA group. Results: Compared with that in the control group, there were statistically significant reduction of both the 12-h and total postoperative blood loss in the TXA group [6.573 ± 0.144 vs. 5.499 ± 0.133 ml kg-1, mean difference (MD) 1.074 ml kg-1, p < 0.001; 12.183 ± 0.298 vs. 9.973 ± 0.276 ml kg-1, MD, 2.210 ml kg-1, p < 0.001]. There was a statistically significant reduction of the MD of 12-h postoperative blood loss due to TXA in patients aged < 1 year compared with that in patients aged ≥1 year (MD, 1.544 vs. 0.681 ml kg-1, P = 0.007). There were statistically significant reduction of the MD of both the 12-h and total postoperative blood loss due to TXA in patients weighing < 10 kg compared with that in patients weighing ≥10 kg (MD, 1.542 vs. 0.456 ml kg-1, P < 0.001, and MD, 2.195 vs. 0.929 ml kg-1, P = 0.036, respectively). There was a statistically significant reduction of the MD of total postoperative blood loss due to TXA in cyanotic patients compared with that in acyanotic patients (MD, 3.381 vs. 1.038 ml kg-1, P = 0.002). There was no significant difference in the postoperative volume or exposure of allogeneic transfusion, in-hospital morbidity or mortality between the groups. Conclusions: TXA took effects in reduction of postoperative blood loss but not the allogeneic transfusion requirement in pediatric patients undergoing cardiac surgery, particularly in infants weighing < 10 kg and cyanotic children. Moreover, the study suggested the use of TXA was safe in pediatric cardiac surgery.

Abstract
The aim of this randomized controlled trial was to evaluate the effect of tranexamic acid (TXA) on postoperative blood loss during transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH). A total of 60 patients with BPH and undergoing TURP were randomized into TXA and control groups. Patients were intravenously administered 1 g TXA or placebo (0.9% sodium chloride solution), respectively, after the induction of anesthesia for TURP. Intraoperative and postoperative bladder irrigation volumes and blood loss volumes were compared between the two groups. Coagulation function (measured by prothrombin, activated partial thromboplastin and thrombin time and fibrinogen levels) was measured before the operation and at 4 h post-operation. Complications from thromboembolic events, such as lower-limb and pulmonary embolisms, were also noted. The TXA group had significantly decreased blood loss intraoperatively and at 4 h postoperatively compared with the control group (P<0.05). The 24 h postoperative blood loss and coagulation function of the two groups were not significantly different. No thromboembolic events or other complications occurred in either group. In conclusion, a preoperative single dose of TXA was indicated to reduce perioperative blood loss in TURP without a notable increase in thrombosis risk.

Abstract
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. METHODS In April 2014, our Veterans Affairs Medical Center introduced a protocol to administer EACA during THA and TKA. No antifibrinolytics were used previously. We retrospectively compared blood loss and incidence of transfusion among patients who underwent primary arthroplasty in the year before standardized administration of EACA with patients having the same procedures the following year. Blood loss was measured as delta hemoglobin (preoperative hemoglobin - hemoglobin on postoperative day 1). All patients undergoing primary THA or TKA were included. Patients having revision surgery were excluded. RESULTS We identified 185 primary arthroplasty patients from the year before and 184 from the year after introducing the EACA protocol. There were no changes in surgical technique or attending surgeons during this period. Delta hemoglobin was significantly lower in the EACA group (2.7 ± 0.8 mg/dL) compared to the control group (3.4 ± 1.1 mg/dL) (P < .0001). The incidence of blood transfusion was also significantly lower in the EACA group (2.7%) compared to the control group (25.4%) (P < .0001). There was no difference in venous thromboembolic complications between groups. CONCLUSION We demonstrated reductions in hemoglobin loss and transfusion following introduction of the EACA protocol in patients undergoing primary arthroplasty. EACA offers a lower cost alternative to TXA for reducing blood loss and transfusion in this population.

Background Coagulopathy is a major problem in surgery for cyanotic congenital heart disease. Tranexamic acid has been used both topically and systemically and plays a vital role in pediatric cardiac surgery by reducing blood loss and blood product requirement. We aimed to determine the anti-fibrinolytic effectiveness of low-dose systemic or topical tranexamic acid or a combination of both. Methods Seventy-five patients were divided in 3 groups of 25. Group A patients were given tranexamic acid 20 mg kg−1 intravenously after sternotomy and 20 mg kg−1 after heparin reversal. Group B patients were given tranexamic acid 50 mg kg−1 in 20 mL of saline intrapericardially before sternal closure, with the drain clamped for 20 min. Group C patients were given tranexamic acid 20 mg kg−1 intravenously after sternotomy and 50 mg kg−1 intrapericardially before sternal closure. A number of clinical variables were recorded in the first 3 postoperative days. Ventilator time, intensive care unit stay, and outcome were also recorded. Results Chest tube drainage and blood product requirements were lowest in group C. Blood urea and serum creatinine levels were higher in groups A and C ( p < 0.05). Intensive care unit stay and ventilator time were similar in all 3 groups. No patient died and none had a seizure or other neurological event or thromboembolic complication postoperatively. Conclusion The combination of low-dose intravenous and topical tranexamic acid reduces postoperative blood loss and blood product requirement without incurring neurological, renal or thromboembolic complications. We recommend the routine use of topical and low-dose systemic tranexamic acid in cyanotic pediatric cardiac surgery.

Abstract
OBJECTIVES The present study aimed to examine the association between tranexamic acid (TXA) use and adverse effects (seizures, thromboembolism, and renal dysfunction) in a pediatric cardiac surgery population using a national inpatient database in Japan. The authors also assessed the association between TXA use and other clinical outcomes (length of hospital stay and in-hospital mortality). DESIGN A nationwide, retrospective cohort study using propensity score analyses. SETTING Japanese Diagnosis Procedure Combination inpatient database. PARTICIPANTS Pediatric patients who underwent cardiac surgery using cardiopulmonary bypass between July 2010 and March 2014 (N = 11,275). INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Propensity-score matching created 3,739 pairs of patients with and without TXA administration. Propensity-matched analysis showed that the proportion of seizures was significantly higher in the TXA group than in the non-TXA group (1.6% v 0.2%, difference, 1.4%; 95% confidence interval, 1.0-1.9; p<0.001). However, none of the other outcomes was significantly different between the groups. CONCLUSIONS TXA use is associated with a significantly increased risk of seizures. However, there is no difference in any other outcomes between the TXA and non-TXA groups.

Abstract
Background Open heart surgeries under cardiopulmonary bypass are associated with excessive perioperative bleeding that often requires reoperation. Antifibrinolytics like epsilon aminocaproic acid and tranexamic acid are widely used to control bleeding. There are limited studies primarily showing the impact of these drugs on the incidence of reopening following open heart surgical procedures. The goal of this study was to compare incidence of reopening following open heart surgeries in patients who were administered either epsilon amino caproic acid or tranexamic acid for control of perioperative bleeding. Methods A prospective, randomized, controlled trial was performed among seventy-eight patients of either sex in the age group of 18 to 65 years scheduled for open heart surgeries under cardiopulmonary bypass. They were randomly allocated into three groups where group A (n=26) received epsilon aminocaproic acid, group B (n=26) received tranexamic acid and group C (control group, n=26) received intravenous 0.9% normal saline. Patients had similar anaesthetic protocols, and were monitored for twenty-four hours postoperatively to assess reopening rates because of excessive bleeding. Results Two patients in each group receiving either tranexamic acid or epsilon aminocaproic acid had excessive bleeding requiring reopening after surgery whereas three patients in the control group had undergone reopening for excessive bleeding (p>0.05). Conclusions Epsilon aminocaproic acid and tranexamic acid exhibit similar and comparable effect to placebo on incidence of reopening for excessive bleeding following open heart surgeries under cardiopulmonary bypass

Abstract
BACKGROUND The prevalence of tranexamic acid (TXA) use for trauma and other conditions in children is unknown. OBJECTIVES The objective of this study was to describe the use of TXA in United States (US) children's hospitals for children in general, and specifically for trauma. METHODS We conducted a secondary analysis of a large, administrative database of 36 US children's hospitals. We included children <18 years of age who received TXA (based on pharmacy charge codes) between 2009 and 2013. Patients were grouped into the following diagnostic categories: trauma, congenital heart surgery, scoliosis surgery, craniosynostosis/craniofacial surgery, and other, based on the International Classification of Diseases, Ninth Revision principal procedure and diagnostic codes. TXA administration and dosage, in-hospital clinical variables, and diagnostic and procedure codes were documented. RESULTS A total of 35,478 pediatric encounters with a TXA charge were included in the study cohort. The proportions of children who received TXA were similar across the years 2009 to 2013. Only 110 encounters (0.31%) were for traumatic conditions. Congenital heart surgery accounted for more than one-half of the encounters (22,863; 64%). Overall, the median estimated weight-based dose of TXA was 22.4 mg/kg (interquartile range, 7.3-84.9 mg/kg). CONCLUSIONS We identified a wide frequency of use and range of doses of TXA for several diagnostic conditions in children. The use of TXA among injured children, however, appears to be rare despite its common use and efficacy among injured adults. Additional work is needed to identify appropriate indications for TXA and provide dosage guidelines among children with a variety of conditions, including trauma.

Abstract
BACKGROUND Severe blood loss is a common complication of craniofacial reconstruction surgery. The antifibrinolytic ε-aminocaproic acid (EACA) reduces transfusion requirements in children undergoing cardiac surgery and in older children undergoing spine surgery. Tranexamic acid (TXA), another antifibrinolytic with a similar mechanism of action, has been shown to reduce blood loss and transfusion requirements in children undergoing craniofacial surgery. However, TXA has been associated with an increase in post-operative seizures and is more expensive than EACA. There is currently little published data evaluating the efficacy of EACA in children undergoing craniofacial surgery. METHODS This is a retrospective study of prospectively collected data from our craniofacial perioperative registries for children under 6 years of age who underwent anterior or posterior cranial vault reconstruction. We compared calculated blood loss, blood donor exposures, and post-operative drain output between subjects who received EACA and those who did not. RESULTS The registry queries returned data from 152 subjects. Eighty-six did not receive EACA and 66 received EACA. The EACA group had significantly lower calculated blood loss (82 ± 43 vs. 106 ± 63 ml/kg, P = 0.01), fewer intraoperative blood donor exposures (median 2, interquartile range 1-2 vs. median 2, interquartile range 1-3; P = 0.02) and lower surgical drain output in the first post-operative 24 h (28 ml/kg vs. 37 ml/kg, P = 0.001) than the non-EACA group. CONCLUSION In this analysis of prospectively captured observational data, EACA administration was associated with less calculated blood loss, intraoperative blood donor exposures, and post-operative surgical drain output.

Abstract
Children with cyanotic congenital heart disease (CCHD) have complex alterations in their whole blood composition and coagulation profile due to long-standing hypoxemia. Secondary erythrocytosis is an associated physiological response intended to increase circulating red blood cells and oxygen carrying capacity. However, this response is frequently offset by an increase in whole blood viscosity that paradoxically reduces blood flow and tissue perfusion. In addition, the accompanying reduction in plasma volume leads to significant deficiencies in multiple coagulation proteins including platelets, fibrinogen and other clotting factors. On the one hand, these patients may suffer from severe hyperviscosity and subclinical 'sludging' in the peripheral vasculature with an increased risk of thrombosis. On the other hand, they are at an increased risk for postoperative hemorrhage due to a complex derangement in their hemostatic profile. Anesthesiologists caring for children with CCHD and secondary erythrocytosis need to understand the pathophysiology of these alterations and be aware of available strategies that lessen the risk of bleeding and/or thrombosis. The aim of this review is to provide an updated analysis of the systemic effects of long-standing hypoxemia in children with primary congenital heart disease with a specific focus on secondary erythrocytosis and hemostasis.

Abstract
Introduction: Excessive fibrinolysis contributes to post-cardiopulmonary bypass bleeding. Tranexamic Acid (TXA) and Caproamin Fides are synthetic lysine analogues that inhibit plasminogen-fibrin binding. The present study aimed to compare TXA and Caproamin Fides versus placebo in patients undergoing elective coronary artery revascularization.
Methods: We analyzed perioperative data of 300 adult patients undergoing coronary artery revascularization. Patients were randomly allocated to receive TXA (n=100), Caproamin Fides (n=100) or placebo (n=100) during perioperative time. Mediastinal bleeding during the first 24 hours post-operation, transfusion requirement and post-surgical complications were assessed.
Results: Most descriptive and intra-operative parameters were well comparable between the 3 study groups. Except for mean number of packed red blood cell (PRBC) units transfused during ICU stay (P=0.01), patients in the Caproamin Fides and TXA groups did not show any statistically significant differences regarding transfusion of blood products during peri-operative period. There was no evidence of a significant difference in mediastinal blood loss during the first 24 hours post-operation between the patients receiving TXA or placebo, while patients in the Caproamin Fides group had significantly lower mediastinal bleeding than the other 2 groups (Caproamin Fides vs. placebo, P=0.002, <0.001 and <0.001 at 6, 12 and 24 hours post-operation; Caproamin Fides vs. TXA, P=0.009, 0.003, <0.001 at 6, 12 and 24 hours post-operation). The incidence of postoperative complications were comparable between Caproamin Fides and TXA groups (P>0.05).
Conclusion: In conclusion, Caproamin Fides seems to be superior to TXA regarding the blood saving effects in patients undergoing coronary artery revascularization.

Abstract
Children undergoing major surgery are frequently exposed to a high risk of blood loss often requiring transfusion. Although the risks associated with blood product transfusion have considerably decreased over the last decade, transfusion is still associated with significant morbidity and mortality. Thus, rigorous efforts should be made to decrease surgical bleeding and the need for blood product transfusion. Antifibrinolytic drugs have been shown to be effective when used in both adult and pediatric surgical patients. While there are data in adults to support safety, data remain limited for pediatric patients. Since the restriction of aprotinin use in 2008, the most commonly used antifibrinolytic drugs have been the lysine analogs, tranexamic acid (TXA), and ε-aminocaproic acid, which inhibit the conversion of plasminogen to plasmin and decrease the degree of fibrinolysis. We performed a systematic review of the literature pertaining to the efficacy of antifibrinolytic drugs in children undergoing noncardiac surgery. During spine surgery, both TXA and ε-aminocaproic acid decrease blood loss and transfusion requirements; however, this information comes from small, mainly retrospective trials. Two prospective, randomized, controlled trials have tested the efficacy of TXA in children undergoing craniofacial surgery and have reported that TXA decreases transfusion requirements. Two pharmacokinetic trials were also recently published and are summarized in this review. No data have been published regarding the efficacy of TXA administration in the pediatric trauma population. Further data are still needed in this field of study, and we discuss some perspectives for future research.

Abstract
Antifibrinolytic drugs have become almost ubiquitous in their use during major surgery when bleeding is expected or commonplace. Inhibition of the fibrinolytic pathway after tissue injury has been consistently shown to reduce postoperative or traumatic bleeding. There is also some evidence for a reduction of perioperative blood transfusion. However, evidence of complications associated with exaggerated thrombosis also exists, although this appears to be influenced by the choice of the individual agent and the dose administered. There is controversy over the use of the serine protease inhibitor aprotinin, whose license was recently withdrawn but may shortly become available on the market again. In the UK, tranexamic acid, a tissue plasminogen and plasmin inhibitor, is most commonly used, with evidence for benefit in cardiac, orthopaedic, urological, gynaecological, and obstetric surgery. In the USA, ε-aminocaproic acid, which also inhibits plasmin, is commonly used. We have reviewed the current literature for this increasingly popular class of drugs to support clinical judgement in daily anaesthetic practice.
