OBJECTIVEThe purpose of this study was to investigate the effect of tranexamic acid (TXA) compared to placebo in low-risk adult patients undergoing elective minor lumbar spine surgery—specifically with respect to operative time, estimated blood loss, and complications. Studies have shown that TXA reduces blood loss during major spine surgery. There have been no previous studies on the effect of TXA in minor lumbar spine surgery in which these variables have been evaluated.METHODSThe authors enrolled patients with ASA grades 1 to 2 scheduled to undergo lumbar decompressive surgery at Middelfart Hospital into a double-blind, randomized, placebo-controlled, parallel-group study. Patients with thromboembolic disease, coagulopathy, hypersensitivity to TXA, or a history of convulsion were excluded. Patients were randomly assigned, in blocks of 10, to one of 2 groups, TXA or placebo. Anticoagulation therapy was discontinued 2–7 days preoperatively. Prior to the incision, patients received either a bolus of TXA (10 mg/kg) or an equivalent volume of saline solution (placebo). Independent t-tests were used to compare differences between the 2 groups, with statistical significance set at p < 0.05.RESULTSOf the 250 patients enrolled, 17 patients were excluded, leaving 233 cases for analysis (117 in the TXA group and 116 in the placebo group). The demographics of the 2 groups were similar, except for a higher proportion of women in the TXA group (TXA 50% vs placebo 32%, p = 0.017). There was no significant between-groups difference in operative time (49.53 ± 18.26 vs 54.74 ± 24.49 minutes for TXA and placebo, respectively; p = 0.108) or intraoperative blood loss (55.87 ± 48.48 vs 69.14 ± 83.47 ml for TXA and placebo, respectively; p = 0.702). Postoperative blood loss measured from drain output was 62% significantly lower in the TXA group (13.03 ± 21.82 ml) than in the placebo group (34.61 ± 44.38 ml) (p < 0.001). There was no significant difference in number of dural lesions or postoperative spinal epidural hematomas, and there were no thromboembolic events.CONCLUSIONSTranexamic acid did not have a statistically significant effect on operative time, intraoperative blood loss, or complications. This study gives no evidence to support the routine use of TXA during minor lumbar decompressive surgery.Clinical trial registration no.: NCT03714360 (clinicaltrials.gov)

Study Design: Randomized control trial. Objective: The purpose of the study is to evaluate the safety and efficacy of tranexamic acid in reducing blood loss when administered through various routes in instrumented spine surgeries. Methods: A total of 104 patients undergoing instrumented spine surgery were randomly assigned to 4 groups (n = 26 in each group). Groups included (1) ivTXA—intravenous administration of tranexamic acid (TXA) 1 hour prior to surgery, (2) loTXA—local infiltration of TXA bilaterally into the paraspinal musculature prior to incision, (3) tTXA—topical application of TXA just before wound closure, and (4) control group. Outcome measures included intraoperative blood loss, postoperative blood loss, need for blood transfusion, length of hospital stay, and hematological parameters. Results: All the 3 different modes of TXA administration were found to be effective in reducing blood loss in the treated groups compared with the control group. Intraoperative blood loss was significantly reduced in ivTXA (223.6 ± 40.1 mL, P < .0001) and loTXA (256.07 ± 119 mL, P = .0039) groups when compared with controls (344 ± 88.5 mL).The postoperative blood loss was least in tTXA followed by ivTXA, loTXA, and controls. There was 67% reduction in need for blood transfusion in tTXA group, 55.5% reduction in ivTXA group, and 33% reduction in loTXA group when compared with the control group. Conclusion: In instrumented spine surgery, ivTXA and loTXA were found to be equally effective in reducing the intraoperative blood loss. The tTXA has better postoperative blood conserving effects. This is the first study to detail about safety and efficacy on local infiltration of TXA in spine surgery, which is an effective and safe method for reducing intraoperative blood loss.

OBJECTIVEBlood transfusions are given to approximately one-fifth of patients undergoing elective lumbar spine surgery, and previous studies have shown that transfusions are accompanied by increased complications and additional costs. One method for decreasing transfusions is administration of tranexamic acid (TXA). The authors sought to evaluate whether the cost of TXA is offset by the decrease in blood utilization in lumbar spine surgery patients.METHODSThe authors retrospectively reviewed patients who underwent elective lumbar or thoracolumbar surgery for degenerative conditions at a tertiary care center between 2016 and 2018. Patients who received intraoperative TXA (TXA patients) were matched with patients who did not receive TXA (non-TXA patients) by age, sex, BMI, ASA (American Society of Anesthesiologists) physical status class, and surgical invasiveness score. Primary endpoints were intraoperative blood loss, number of packed red blood cell (PRBC) units transfused, and total hemostasis costs, defined as the sum of TXA costs and blood transfusion costs throughout the hospital stay. A subanalysis was then performed by substratifying both cohorts into short-length (1–4 levels) and long-length (5–8 levels) spinal constructs.RESULTSOf the 1353 patients who met inclusion criteria, 68 TXA patients were matched to 68 non-TXA patients. Patients in the TXA group had significantly decreased mean intraoperative blood loss (1039 vs 1437 mL, p = 0.01). There were no differences between the patient groups in the total costs of blood transfusion and TXA (p = 0.5). When the 2 patient groups were substratified by length of construct, the long-length construct group showed a significant net cost savings of $328.69 per patient in the TXA group (p = 0.027). This result was attributable to the finding that patients undergoing long-length construct surgeries who were given TXA received a lower amount of PRBC units throughout their hospital stay (2.4 vs 4.0, p = 0.007).CONCLUSIONSTXA use was associated with decreased intraoperative blood loss and significant reductions in total hemostasis costs for patients undergoing surgery on more than 4 levels. Furthermore, the use of TXA in patients who received short constructs led to no additional net costs. With the increasing emphasis put on value-based care interventions, use of TXA may represent one mechanism for decreasing total care costs, particularly in the cases of larger spine constructs.

Background: Tranexamic acid (TXA) has been widely used during craniofacial and orthognathic surgery (OS). However, results of the literature are inconsistent due to specific type of surgery and a small sample of studies. The purpose of this study was to evaluate the role of TXA in bimaxillary OS. Methods: We performed a comprehensive literature search of PubMed, Cochrane Central Register of Controlled Trials, and EMBASE to identify randomized controlled trials (RCTs) that compared effect of TXA on bimaxillary OS with placebo. Outcomes of interests included intraoperative blood loss, allogenic transfusion, operation time, and volume of irrigation fluid. Random effects models were chosen considering that heterogeneity between studies was anticipated, and I 2 statistics were used to test for the presence of heterogeneity. Results: Totally 6 RCTs were identified. Tranexamic acid resulted in significantly reduced intraoperative blood loss (weighted mean difference [WMD] = −264.82 mL; 95% CI: −380.60 to −149.04 mL) and decreased amounts of irrigation fluid (WMD = −229.23 mL; 95% CI: −399.63 to −58.83 mL). However, TXA had no remarkable impact on risk of allogenic blood transfusion (pooled risk ratio = 0.50; 95% CI: 0.20-1.23), operation time (WMD = −8.71 min; 95% CI: −20.98 to 3.57 min), and length of hospital stay (WMD = −0.24 day; 95% CI: −0.62 to 0.14 day). No TXA-associated severe adverse reactions or complications were observed. Conclusions: Currently available meta-analysis reveals that TXA is effective in decreasing intraoperative blood loss; however, it does not reduce the risk of allogenic blood transfusion in bimaxillary OS.

Abstract Background Tranexamic acid (TXA) is an antifibrinolytic that has become widely used in aesthetic facial plastic surgery, although its efficacy has not been well investigated. Objectives To evaluate the existing evidence for use of TXA in aesthetic facial plastic surgery, highlighting routes of administration, dosing, surgical applications, and clinical outcomes. Methods Systematic review of primary literature evaluating TXA in aesthetic facial plastic surgery. Results Eleven studies met inclusion criteria: 8 prospective randomized controlled trials, 2 retrospective case series/cohort studies, and 1 clinical opinion. Six studies evaluated TXA in rhinoplasty, 4 in rhytidectomy, and 1 in blepharoplasty. Significant reductions in intraoperative blood loss were found in 5 rhinoplasty studies. Three rhinoplasty and 2 rhytidectomy studies found significantly reduced postoperative edema and ecchymosis. One rhinoplasty and 1 rhytidectomy study reported reduced operative time and time to achieve hemostasis. One rhytidectomy study reported reduced postoperative drain output and faster time to drain removal. No studies reported an adverse outcome directly related to TXA. Conclusions Existing literature investigating TXA in aesthetic facial plastic surgery is sparse with varying levels of evidence and heterogeneous data. Literature suggests systemic TXA reduces intraoperative blood loss during rhinoplasty, although the clinical significance of this blood loss reduction is unclear. TXA may also reduce postoperative edema and/or ecchymosis in rhytidectomy and rhinoplasty, although the lack of validated grading scales yields insufficient evidence to support this claim. Topical and subcutaneously injected TXA are emerging administration routes in rhytidectomy, with evidence suggesting TXA mixed with tumescent may reduce postoperative drain output, thereby expediting drain removal. Level of Evidence: 2

Abstract Background Placenta accreta is an obstetric emergency and the main cause of maternal morbidity and mortality due to the associated bleeding and coagulopathy. Tranexamic acid has been widely used to decrease blood loss in trauma patients and patients with postpartum hemorrhage. We aimed at studying the effect of tranexamic acid in reducing blood loss and blood transfusion in patients with placenta accreta. Methods In a double-blinded randomized controlled study, 46 patients were recruited and divided into two groups, Group A is the tranexamic group where patients received 10 mg/kg tranexamic acid after cord clamping and continued on tranexamic infusion 10 mg/kg/h till the end of the surgery. Group B is the placebo where patients received normal saline instead. Primary outcome was the amount of intraoperative blood loss, and other outcomes included the number of blood and blood products transfused intraoperative and in the first 24 h postoperative, the immediate postoperative Hb level, platelet count, and coagulation profile. Data were collected, coded, tabulated, and then analyzed using Minitab® 16.1.0 statistics software package. Variables were presented as mean and standard deviation and analyzed using unpaired t test. Any difference with p value < 0.05 was considered statistically significant. Results Amount of intraoperative blood loss was significantly less in the tranexamic group 2232 ± 1204 ml compared to the placebo group 3405 ± 1193 ml (p value 0.002), and patients in the tranexamic group received less units of packed red blood cells, fresh frozen plasma, and platelets compared to those in the placebo group (4.2 ± 1.9 vs 6.1 ± 2.2 with p value 0.003, 3.4 ± 1.3 vs 4.2 ± 1.2 with P value 0.036 and 4.8 ± 2.1 vs 6.2 ± 2.4 with p value 0.041, respectively). There was no statistically significant difference in the first postoperative Hb level, platelet count, and coagulation profile between the two groups; however, the amount of blood and products transfused in the first 24 h postoperative were significantly less in the tranexamic group Conclusion Tranexamic acid infusion was effective in reducing intraoperative blood loss and intraoperative and postoperative blood and blood products’ transfusion.

Background Patients with end-stage liver disease frequently incur large-volume blood loss during liver transplantation associated with mechanical factors, preexisting coagulopathy, and intraoperative fibrinolysis. Methods Between April 1992 and May 1994, the authors of this double-blind, randomized, placebo-controlled study examined the effect of high-dose tranexamic acid (maximum of 20 g) on blood loss and blood product requirements in patients undergoing primary isolated orthotopic liver transplantation. Primary outcome measures were volume of blood loss (intraoperative blood loss and postoperative drainage) and erythrocyte, plasma, platelet, and cryoprecipitate use during surgery and the first 24 h of intensive care unit stay. Results Patients receiving tranexamic acid (n = 25) had less intraoperative blood loss (median, 4.3 l; interquartile range, 2.5 to 7.9; P = 0.006) compared with the placebo group (n = 20; median, 8 l; interquartile range, 5 to 15.8), and reduced intraoperative plasma, platelet, and cryoprecipitate requirements. Median perioperative erythrocyte use was 9 units (interquantile range, 4 to 14 units) in patients receiving tranexamic acid and 13 units (interquantile range, 7.5 to 31 units) in controls (P = 0.03). Total perioperative donor exposure was 20.5 units (interquantile range, 16 to 41 units) in patients receiving tranexamic acid and 43.5 units (interquantile range, 29.5 to 79 units) in controls (P = 0.003). Results for postoperative wound drainage were similar. Hospital stay and need for retransplantation were comparable in both groups. No patient in either group showed clinical evidence of hepatic artery or portal venous thrombosis within 1 month of transplantation. Conclusions High-dose tranexamic acid significantly reduces intraoperative blood loss and perioperative donor exposure in patients with end-stage parenchymal liver disease who are undergoing orthotopic liver transplantation, with marked reductions in platelet and cryoprecipitate requirements.
