Effects of 60 degrees of flexion and perioperative use of tranexamic acid on recovery after knee replacement

Abstract OBJECTIVE To explore the effect of 60 knee flexion combined with multiple tranexamic acid application on postoperative recovery of knee replacement patients. METHODS Knee replacement patients admitted to our hospital from October 2020 to September 2022 were selected as the study subjects, and randomly divided into two groups. Postoperative D-dimer, prothrombin time and partial thrombin time were recorded in the two groups, and the differences between the two groups were compared. Erythrocyte, hemoglobin and erythrocyte volume were recorded before, 1 day and 3 days after surgery and the affected limb circumference were also assessed. RESULTS On the 1st and 3rd day after surgery, the red blood cells, hemoglobin, and hematocrit levels in the experimental group were higher than those in the control group, and the differences were statistically significant(P<0.05). The difference in VAS score and circumference between the two groups on the 1st day and 3rd day after surgery was compared, and the difference was statistically significant. The difference in VAS score and circumference was lower in the control group(P<0.05). After surgical treatment, knee joint function recovered, knee joint mobility and HSS score improved, and the difference between the experimental groups was statistically significant (P<0.05). CONCLUSION Perioperative 60-degree flexion combined with multiple tranexamic acids can significantly reduce blood loss in patients undergoing knee replacement surgery, increase red blood cells, hemoglobin levels and red blood cell volume on postoperative days 1 and 3, and reduce postoperative swelling of the affected limb.

The efficacy and application of tranexamic acid in emergency medicine: Emergency Medicine Association of Türkiye clinical policy- 2024

Abstract The clinical policy of the Emergency Medicine Association of Türkiye (EMAT) provides guidance on the use of tranexamic acid (TXA) in emergency settings. TXA, an antifibrinolytic drug, is used to control bleeding by inhibiting plasminogen. Its applications have expanded from hemophilia and severe menstrual bleeding to include various forms of trauma and surgery-related bleeding. Despite its potential benefits, the use of TXA in emergency settings must be carefully evaluated due to its associated risks, including venous thromboembolism. This policy aimed to offer evidence-based recommendations on the indications and contraindications of TXA in different clinical scenarios encountered in the emergency departments. The guidelines were developed using the “Grading of Recommendations, Assessment, Development, and Evaluations” approach, incorporating systematic literature reviews, and expert consensus from the EMAT Research Committee. This document focuses on critical clinical questions regarding the efficacy and safety of TXA in situations such as gastrointestinal bleeding, multitrauma, traumatic brain injury, nontraumatic intracranial hemorrhage, hemoptysis, and epistaxis. By addressing these issues, the policy seeks to assist emergency physicians in making informed decisions about the use of TXA, ultimately aiming to improve the patient outcomes.

Systemic vs. in-irrigation tranexamic acid in percutaneous nephrolithotomy A systematic review, Bayesian network meta-analysis, and meta-regression.

Percutaneous nephrolithotomy (PCNL) is the gold-standard treatment for large renal stones. One potentially significant complication of PCNL is blood loss, which can result in transfusion requirement and poorer stone-free outcomes. Tranexamic acid (TXA) has emerged as a promising intervention, administered systemically (TXA-S) or as part of irrigation fluid (TXA-I) in endourology. This study aimed to comprehensively analyze existing evidence regarding the applications of TXA in PCNL through a Bayesian network meta-analysis, offering insights into its efficacy and comparative effectiveness. In February 2022, a PRISMA-compliant systematic review (PROSPERO registration number CRD 42021270593) was performed to identify randomized controlled clinical trials (RCT) on TXA as either systemic therapy or in irrigation fluid. Studies in languages other than English and Spanish were not considered. A Bayesian network was built using results from identified studies to create models that were later run through Markov Chain Monte Carlo sampling through 200 000 iterations. Eight RCTs compared TXA-S vs. placebo, one TXA-I vs. placebo, and one TXA-I vs. TXA-S. TXA-I had lower risk of transfusion (relative risk [RR] 0.63 [0.47,0.84], SUCRA 0.950) than TXA-S (RR 0.79 [0.65,0.95], SUCRA 0.545). TXA-I had a lower risk of complications (RR 0.38 [0.21,0.67], SUCRA=0.957) compared to TXA-S (RR 0.55 [0.39, 0.78], SUCRA 0.539). TXA-I had a lower postoperative decrease in hemoglobin (mean difference [MD] -1.2 [1.3, 1.0], SUCRA 0.849) compared to TXA-S (MD -0.97 [-1.0, -0.93], SUCRA 0.646]). TXA, regardless of the route of administration, is an effective intervention in decreasing bleeding, postoperative complications, and risk of transfusion when compared with placebo. Further studies directly comparing TXA-S to TXA-I would be useful to determine the optimal route of delivery.

The effects of chlorhexidine gel and tranexamic acid application after tooth extraction on the risk of alveolar osteitis formation: a double blind clinical study.

Alveolar osteitis(AO), one of the most common complications occurring in 1-10% of cases following tooth extraction, occurs due to the disruption of clot formation in the extraction socket. This study aims to evaluate the effect of using absorbable gelatin sponge, chlorhexidine gel, and tranexamic acid agents on the development of AO following extraction. Between March and October 2023, the teeth of 98 healthy patients (average age: 38, range: 19-62) with extraction indications were extracted at Recep Tayyip Erdoğan University, Faculty of Dentistry, Department of Oral and Maxillofacial Surgery. 113 extraction sockets(85 molars and 28 premolars) were randomly treated with absorbable gelatin sponge(AGS), chlorhexidine gel with AGS, and tranexamic acid with AGS. Pain and edema levels were recorded using visual analog scale(VAS) ranging from 0 to 10 by the patients. Additionally, presence of halitosis, trismus and exposed bone was noted on forms on 3rd and 7th days (recorded as present or absent). The study prospectively aimed to prevent AO using 3 different dental agents in the extraction sockets. Statistical analyses of the study were conducted using the SPSS software package. Alveolitis was observed in 12 out of 113 tooth extractions(%10.6). Pain and edema scores significantly decreased in absorbable gelatin sponge group on the 7th day (p < 0.05). Pain score on the 7th day in chlorhexidine group and age, edema score on the 7th day in tranexamic acid group, were found to be significantly higher (p < 0.05). Incidence of AO, can be reduced by placing agents in the extraction socket, preventing post-extraction pain experienced by patients. NCT06435832.

The effect of topical tranexamic acid with micro-needling and micro-needling alone in treatment of macular amyloidosis.

Macular amyloidosis is a form of primary localized cutaneous amyloidosis presented by pruritic pigmented macules in rippled or reticulate pattern. The aim of this study was to assess the efficacy of using topical tranexamic acid with micro-needling comparing to micro-needling alone in patients with macular amyloidosis. Patients with bilaterally located macular amyloidosis on trunk or upper extremities were recruited in this trial. The skin lesions in all patients were divided into two parts which were randomly assigned to the group of treatment with micro-needling plus tranexamic acid and the group of micro-needling alone. There were four sessions of treatment with 2 weeks interval. The percentage of improvement in pigmentation (based on photographs and dermoscopy) and rippling of each group was determined by three blinded dermatologists. The level of patient satisfaction and reduction of pruritus was measured by a questionnaire and defined as a percentage. Twenty females were enrolled in this study. The mean (SD) patients' age was 39.7 (±10.13) years. Both groups showed improvement in pigmentation based on images, dermoscopy, and rippling pattern. Patients' satisfaction was 46.5% in tranexamic acid group and 47.5% in micro-needling alone. Nevertheless, there was no significant difference between both groups (p value >0.05). Interestingly, the pruritus improved 61.66% after four sessions of treatment in both groups. Micro-needling is a suitable modality for decreasing pruritus and pigmentation in macular amyloidosis. However, topical application of tranexamic acid does not lead to additional improvement.

Topical Tranexamic Acid on Donor Wounds in Burn Patients: A Randomized Placebo-controlled Trial.

Patients with major burn injuries are prone to massive blood loss owing to tangential excision of burn wounds and donor skin harvesting. In general, topical application of the antifibrinolytic drug tranexamic acid (TXA) to surgical wounds reduces bleeding; however, its effect on bleeding and re-epithelialization in superficial wounds of burns has not been explored. This study aimed to investigate the therapeutic potential of topical TXA in reducing blood loss and its effect on wound re-epithelialization in burn surgery. Split-thickness skin graft donor wounds in burn patients were paired and randomized to topical application of either TXA (25 mg/mL) or placebo. Endpoints were postoperative bleeding as measured by dressing weight gain per cm2 wound area, blood stain area per wound area, and visual evaluation of bleeding in the dressings. Healing time was recorded to analyze the effect on wound re-epithelialization. There was no significant difference in bleeding or time to re-epithelialization between the TXA and placebo wounds. A post hoc subanalysis of wounds with dressing weight gain above the median, showed a significant difference in favor of TXA. However, use of tumescence may have influenced end points. No significant adverse events related to the study drugs were observed. This study demonstrates that topical application of TXA (25 mg/mL) to split-thickness skin graft donor wounds does not delay re-epithelialization. Although a reduction in bleeding is suggested, further studies are needed to determine the role of topical TXA in reducing bleeding in burn surgery.

The advantages of using tranexamic acid in anterior cruciate ligament reconstruction: a randomized controlled trial.

The number of participants in sports or some form of recreation globally has led to an increase in the incidence of anterior cruciate ligament (ACL) injuries and the number of surgeries performed. Although it does not belong to risky surgical interventions, this operation is accompanied by complications that slow down post-operative rehabilitation. The objective is to analyze the effects of intra-articular (IA) injection of tranexamic acid (TXA) on the reduction of post-operative drained blood volume, pain intensity, and incidence of hemarthrosis after ACL reconstruction. This prospective research included 124 patients undergoing ACL reconstruction surgery, randomly divided into two groups. The TXA group received IA TXA, whereas an equal amount of placebo was administered using the same route in the control group. The research has shown that IA injection of TXA effectively reduces post-operative blood loss (TXA group 71.29 ± 40.76 vs. control group 154.35 ± 81.45), reducing the intensity of post-operative pain (p < 0.001) and the incidence of hemarthrosis. The application of TXA significantly reduced post-operative bleeding and pain intensity, which accelerated the post-operative period.

Evaluation of therapeutic efficacy of tranexamic acid compared to modified Kligman formula in the management of melasma

Background: Facial melanoses (FM) are a common presentation in Indian patients, causing cosmetic disfigurement with considerable psychological impact. Melasma is an acquired non-inflammatory hypermelanosis of multifactorial etiology with significant cosmetic deformity. Different treatment modalities have been tried in different studies with varying outcomes. Recent clinical trials with tranexamic acid (TXA) are promising. Objective: To compare the therapeutic efficacy of TXA topical application after micro-needling and intralesional TXA with the modified Kligman formula in the management of melasma. Materials and Methods: This is a prospective, randomized, open-label study with a sample size of 45 patients with melasma fulfilling inclusion and exclusion criteria. They were randomly divided into three groups of 15 each. Group A individuals were advised to apply a modified Kligman formula daily at night for 3 months, Group B individuals weekly micro-needling followed by TXA application for 3 months, and Group C individuals intralesional TXA (4 mg/mL) weekly for 3 months. Clinical and dermoscopic images were taken at each visit, including modified Melasma Area Severity Index (MASI) scoring, patient global assessment, and physician global assessment to assess the clinical response. Results: Group A showed a 42% improvement in MASI score by the end of 12 weeks, Group B showed a 30% improvement, and Group C showed a 36% improvement. When statistically compared with the Analysis of Variance test, there was no significant difference (P = 0.62) between the three groups. However, in individual groups, there was a significant difference (P &lt; 0.05) in MASI at 0 and 12 weeks. Dermoscopic images showed perilesional hypopigmentation and telangiectasias with a modified Kligman formula, which was not seen with TXA. Patient assessment score revealed satisfaction with the modified Kligman formula because of home application and lack of pain. Conclusion: The modified Kligman formula is found to be superior in the treatment of melasma, because of the synergistic activity of its components. However, it has its demerits of long-term usage like hypopigmentation and telangiectasias. Hence, TXA that showed comparable results with the Kligman formula can be used either as a primary modality or as an adjuvant supportive therapy for maintenance.

Clinical application of tranexamic acid in arthroscopic rotator cuff repair surgery: A randomized controlled trial.

To investigate whether intravenous administration of tranexamic acid (TXA) prior to arthroscopic rotator cuff repair improves operative blood loss, postoperative fibrinolytic index, inflammatory response, and postoperative pain. This was a prospective, double-blind, randomized controlled study. From January 2023 to February 2024, 64 patients who required arthroscopic rotator cuff repair were included and divided into tranexamic acid group (T group) group and control group (C group) according to the random number table method. In T group, 1000 mg TXA was administered intravenously 10 minutes before surgery, and an equivalent dose of normal saline was administered intravenously 10 minutes before surgery in C group. Intraoperative bleeding, postoperative fibrinolytic indexes, inflammatory indexes, pain scores, and occurrence of adverse effects were compared between the 2 groups. Intraoperative bleeding in T group was lower than that in C group (P < .05); D-D and FDP in T group were significantly lower than those in C group (P < .05); postoperative TNF-α and IL-6 in 2 groups was higher than that before operation and T group was lower than C group (P < .05); The pain scores of the 2 groups after operation were lower than those before operation (P < .05), and there was no difference between the 2 groups (P > .05). TXA is able to reduce blood loss and inflammatory reactions, modulate fibrinolytic function, and promote postoperative recovery in patients undergoing arthroscopic rotator cuff repair, with no elevated risk of complications.

Clinical Efficacy of Intra-articular Tranexamic Acid Injection in the Management of Hemophilia with Total Hip Arthroplasty: A 24-month Retrospective Cohort Study.

Total hip arthroplasty (THA) effectively treats end-stage hemophilic hip arthropathy. Given hemophilia's unique characteristics, perioperative bleeding remains a significant risk for patients undergoing THA. Tranexamic acid (TXA), an efficient antifibrinolytic agent, may benefit the outcomes of THA for patients with hemophilia (PWH). This study aims to explore the clinical efficacy of intra-articular injection of TXA in treating perioperative bleeding in PWH and assess its additional clinical benefits. The retrospective study comprised data of PWH who received THA from January 2015 to December 2021 in the research center. A total of 59 individuals were included in the study, divided into a TXA group (n = 31) and a non-TXA group (n = 28). We compared various parameters, including total blood loss (TBL), visible blood loss (VBL), occult blood loss (OBL), intraoperative coagulation factor VIII (FVIII) consumption, perioperative total FVIII consumption, hemoglobin (HB), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), length of hospital stay, hospitalization costs, length of surgery, total protein, activated partial thromboplastin time (APTT), D-dimer, rate of joint swelling, hip joint range of motion (ROM), visual analogue scale (VAS), and Harris hip joint function scale (HHS) between the two groups. Follow-up assessments were conducted for up to 24 months. A Student's t test was utilized for the statistical analysis. This study demonstrated that intra-articular TXA effectively reduced TBL (1248.19 ± 439.88 mL, p < 0.001), VBL (490.32 ± 344.34 mL, p = 0.003), and OBL (757.87 ± 381.48 mL, p = 0.004) in PWH who underwent THA. TXA demonstrated effectiveness in reducing VAS scores on POD1, POD7, and POD14 and joint swelling rates on POD1, POD7, POD14, and at discharge (p < 0.05). Additionally, the TXA group achieved higher HHS ratings at all follow-up time points (p < 0.05), showing superior hip joint mobility, lower postoperative inflammation levels, reduced factor VIII consumption during surgery, and less postoperative nutritional loss. No statistically significant differences were observed between the two groups in terms of hospital stay, hospitalization costs, surgery duration, and coagulation indicators. Intra-articular injection of TXA reduces perioperative bleeding in PWH undergoing THA while also improving joint mobility, post-operative rehabilitation, and quality of life. This may provide value for the future application of TXA in PWH.

Total blood loss and early clinical outcomes under different tranexamic acid regimes in total knee arthroplasty.

Many different regimes of intravenous and local tranexamic acid (TXA) reduce total blood loss (TBL) in patients undergoing total knee arthroplasty (TKA). However, the most effective TXA regime in reducing blood loss might not be most beneficial for the patient. The aim of the present study was to investigate the effect of commonly used TXA regimes on blood loss and on early clinical outcomes. We performed this monocentric retrospective study in patients undergoing primary TKA. Primary outcome was the estimated TBL. Secondary outcomes were the rates of adverse events (AE) as well as the range of motion (ROM), mobility and pain intensity during the first three physiotherapy sessions (PTS). We analysed the data of 1250 TKAs. 5 different TXA regimes were applied. TBL (mean ± SE) was 953 ± 64ml (2xiv), 999 ± 19ml (2xiv + 1xlocal), 1075 ± 19ml (1xiv + 1xlocal), 1191 ± 39ml (1xlocal) and 1241 ± 48ml (1xiv) (p < 0.01). In the linear regression model for TBL a lower number of TXA applications was a predictor for increased blood loss (p < 0.01). AE rates were lowest under 2xiv (0%) and 2xiv + 1xlocal (4.8%). Highest mobility and lowest pain intensity were observed under 1x iv and 2x iv. The largest portions of fully mobile patients on day three were observed under 1xiv (100%), 2xiv (100%) and 2xiv + 1local TXA (86.9%). Our results suggest that multiple applications of TXA are more effective in decreasing blood loss than excessive dosing of TXA. Interestingly, local use of TXA might be associated with higher pain intensity and decreased mobility on the first days after surgery.

Efficacy and Safety of Orally and Intravenously Administration of Tranexamic Acid in Patients with Elderly Femoral Neck Fracture.

For elderly femoral neck fracture patients, anemia is one of the most common complications, increasing the risk of postoperative adverse events. Tranexamic acid (TXA) has been widely applied to the perioperative blood management. However, the optimal route of TXA administration in elderly femoral neck fracture remains unclear. The aim of this study is to evaluate the efficacy and safety of oral and intravenous (IV) application of TXA in elderly patients with femoral neck fracture undergoing total hip arthroplasty (THA) and hemiarthroplasty (HA). All elderly patients aged over 65 years old diagnosed with femoral neck fracture admitted to the trauma orthopedics from August 1, 2020 to February 28, 2022 were enrolled in this prospective cohort study. Participants were divided into three groups: oral group: TXA 2g orally 2 h before incision; IV group: intravenous infusion of TXA 1g 15 min before incision; and control group: usual hemostatic method. The primary outcomes were total blood loss, allogeneic transfusion rate, and postoperative thromboembolic events. SPSS 23.0 (IBM, Armonk, NY, USA) was used for statistical analysis, and p ≤ 0.05 was considered statistically significant. A total of 100 patients were enrolled, including 32 cases in the oral group, 34 cases in the IV group and 34 cases in the control group. Compared with the control group, the total perioperative blood loss in the oral and IV groups was significantly decreased (763.92 ± 358.64 mL vs 744.62 ± 306.88 mL vs 1250.60 ± 563.37 mL, p = 0.048). No significant difference was identified between the oral and IV groups (p = 0.970). The rate of allogeneic transfusion was lower in the oral and IV groups than in the control group, but the difference had no statistical significant (6 vs 5 vs 12, p = 0.108), However, subgroup analysis showed that the IV and oral groups in patients who underwent THA have significant lower transfusion rate compared with the control group (1 vs 3 vs 7, p = 0.02). During 6 months follow-up, no thromboembolic events were identified. Two patients (one from the oral group and one from the control group) died of respiratory failure. The cost of blood management from the oral group was significantly lower than IV (p < 0.001) and control groups (p = 0.009). Elderly patients with femoral neck fracture undergoing THA can benefit from both IV and oral administration of tranexamic acid. The results of these two administration routes are similar in safety and effectiveness. A similar tendency was observed in patients undergoing HA. Oral TXA is more cost-benefit compared with intravenous applications.

The effect of preoperative use of anticoagulants on the hemostatic effect of intravenous application of tranexamic acid in PLIF: a case control study

Intravenous application of tranexamic acid (TXA) in posterior lumbar interbody fusion (PLIF) can effectively reduce blood loss without affecting coagulation function. However, it has not been reported whether preoperative use of anticoagulants may affect the efficacy of TXA in PLIF. The purpose of this study is to observe the effect of preoperative use of anticoagulants on coagulation indicators and blood loss after PLIF receiving intravenous unit dose TXA. A retrospective analysis was conducted on data from 53 patients with PLIF between 2020.11 and 2022.9, who received intravenous application of a unit dose of TXA (1 g/100 mL) 15 min before the skin incision after general anesthesia. Those who used anticoagulants within one week before surgery were recorded as the observation group, while those who did not use anticoagulants were recorded as the control group. The main observation indicators include surgical time, intraoperative blood loss, postoperative drainage volume, blood transfusion, and red blood cell (RBC), hemoglobin (HB), and hematocrit (HCT) measured on the 1st, 4th, 7th, and last-test postoperative days. Secondary observation indicators included postoperative incision healing, deep vein thrombosis of lower limbs, postoperative hospital stay, and activated partial thrombin time (APTT), prothrombin time (PT), thrombin time (TT), fibrinogen (FIB), and platelets (PLT) on the 1st and 4th days after surgery. The operation was successfully completed in both groups, the incision healed well after operation, and no lower limb deep vein thrombosis occurred. There was no significant difference in surgical time, intraoperative blood loss, postoperative drainage volume, and blood transfusion between the two groups (p > 0.05). There was no significant difference in the RBC, HB, and HCT measured on the 1st, 4th, 7th, and last-test postoperative days between the two groups (p > 0.05). There was no statistically significant difference in APTT, PT, TT, FIB and PLT between the two groups on the 1st and 4th postoperative days (p > 0.05). There was no significant difference in postoperative hospital stay between the two groups (p > 0.05). The use of anticoagulants within one week before surgery does not affect the hemostatic effect of intravenous unit dose TXA in PLIF.

The efficacy and safety of different does of intravenous tranexamic acid on blood loss in fresh foot and ankle fractures: a prospective, randomized controlled study

BackgroundThere are a few studies on the effectiveness and safety of intravenous administration of tranexamic acid(TXA) in patients who underwent foot and ankle surgery, especially for preoperative hidden blood loss in patients with freshfoot and ankle fractures. Thus, the aim of this study was to investigate whether intravenous administration of different doses of TXA can effectively reduce perioperative blood loss and blood loss before surgery and to determine its safety.MethodsA total of 150 patients with fresh closed foot and ankle fractures from July 2021 to July 2023 were randomly divided into a control group (placebo controlled [PC]), standard-dose group (low-dose group [LD], 1 g/24 h; medium-dose group [MD], 2 g/24 h), and high-dose group (HD, 3 g/24 h; ultrahigh-dose group [UD], 4 g/24 h). After admission, all patients completed hematological examinations as soon as possible and at multiple other time points postsurgery.ResultsThere was a significant difference in the incidence of hidden blood loss before the operation between the TXA group and the control group, and the effect was greater in the overdose groups than in the standard-dose groups. There were significant differences in surgical blood loss (intraoperative and postoperative), postoperative HGB changes, and hidden blood loss among the groups. The TXA groups showed a significant decrease in blood loss compared to that of the control group, and the overdose groups had a more significant effect than the standard-dose groups. A total of 9 patients in the control group had early wound infection or poor healing, while only 1 patient in the other groups had this complication, and the difference among the groups was significant. No patients in any group suffered from late deep wound infection, cardiovascular or cerebrovascular events or symptomatic VTE.ConclusionThis is the first study on whether TXA can reduce preoperative hidden blood loss in patients with freshfoot and ankle fractures. In our study, on the one hand, intravenous application of TXA after foot and ankle fractures as soon as possible can reduce preoperative blood loss and postoperative blood loss. On the other hand, TXA can also lower wound complications, and over-doses of TXA are more effective than standard doses. Moreover, overdoses of TXA do not increase the incidence of DVT.

Comparative Study of Topical Application of Injection Tranexamic Acid and Anterior Nasal Packing in the Management of Epistaxis.

Epistaxis, defined as bleeding from the nose, is one of the common ENT cases coming to emergency department. Epistaxis is experienced by at least 60% of the population once in their life time and about 6% of them will require medical attention. The different treatment modalities include: local pressure, application of topical vasoconstrictor substances, or nasal packing depending on personal physician preference. Tranexamic acid (TXA), a synthetic analogue of the amino acid lysine, belongs to a class of drugs known as antifibrinolytics. It acts by reversibly binding four to five lysine receptor sites on plasminogen and can be used in emergency department for reducing the bleeding time in epistaxis. To evaluate the efficacy of topical application of injection TXA compared to cases managed with anterior nasal packing for the treatment of patients with epistaxis. 100 patients presenting with epistaxis in emergency department, above the age of 18years were randomly divided into two groups with 50 patients each. Group 1 were managed with anterior nasal packing with gel foam and Group 2 with topical application of injection TXA. Causes,duration to control epistaxis, and occurrence of rebleeding were recorded. Our study showed homogenous distribution of age and sex among the patients. Bleeding stopped within 10min in 38 patients in group 2 compared to 17 patients in group 1. For 31 patients in group 1, bleeding stopped between 10 and 15min compared to 12 in group 2. In group 1, 8 patients had rebleeding compared to 2 patients in group 2. Our study showed that topical application of TXA reduces the bleeding time and number of rebleeds compared to anterior nasal packing with gelfoam. Since it is easily available in an emergency setup and cheaper compared to gelfoam, it can be used as an elective method in managing epistaxis in emergency department.

Tranexamic Acid and Rhinoplasty: How Do Different Administration Routes Affect Effectiveness?

The aim of this study was to evaluate the effectiveness of the intravenous, oral and local application of tranexamic acid in operation time, intraoperative bleeding, postoperative edema and ecchymosis in rhinoplasty. This was a randomized, double-blinded, prospective study. We included 146 patients who underwent rhinoplasty at the Bezmialem Vakif University Medical Faculty Otorhinolaryngology Clinic between April 2021 and April 2022. The patients were divided into four groups: Group 1 (intravenous TXA), Group 2 (oral TXA), Group 3 (topical TXA), and Group 4 (control). Operation time was recorded. Bleeding volume was measured in the suction chamber and nasopharyngeal pack. Postoperative edema and ecchymosis were evaluated using a scale at the end of the operation, on the 1st, 3rd, and 7th days. There was no statistically significant difference between groups in terms of mean operation time (p = 0.894). There was a statistically significant lower mean intraoperative bleeding level in Group 2 from the other groups (p = 0.020). Group 3 had significantly lower scores for postoperative edema than the other groups at the end of the operation, on the 1st, 3rd, and 7th days (p < 0.05), and significantly lower scores for postoperative ecchymosis at the end of the operation (p = 0.013) and on the 3rd day (p = 0.024). Although group 3 had a lower score than the other groups in the ecchymosis measurements on the 1st, and 7th days, no statistically significant results were obtained. Local application of tranexamic acid is founded more beneficial for reducing postoperative edema and ecchymosis in rhinoplasty than intravenous and/or oral applications in this study.

Topical Tranexamic Acid to Control Vaginal Laceration Bleeding after Sexual Assault

BackgroundSexual assault survivors may sustain vaginal trauma that requires intervention in the emergency department, or operating room. Case ReportWe describe the case of a 16-year-old female who was referred to the emergency department for evaluation of continued bleeding from a vaginal laceration following sexual assault 38 h prior. The bleeding limited the medical forensic medical examination, but she was hemodynamically stable. After the application of tranexamic acid (TXA)-soaked gauze, the patient's bleeding was controlled and the wound was able to be evaluated and the examination completed. Why Should an Emergency Physician Be Aware of This?To our knowledge, this is the first case in the literature that describes the use of topical TXA in a patient to achieve hemostasis in a vaginal laceration sustained from sexual violence.

The Use of Tranexamic Acid in Breast Reduction and Abdominoplasty: A Review of a Multicenter Federated Electronic Health Record Database.

Tranexamic acid (TXA), a fibrinolysis inhibitor, is widely used in various surgical fields to minimize blood loss. However, its efficacy and safety in plastic surgery, especially in reduction mammaplasty and abdominoplasty, remain underexplored. This study investigates the utility of intravenous (IV) TXA in these procedures, focusing on reducing postoperative complications and evaluating its safety in the context of venous thromboembolism (VTE). To evaluate the efficacy and safety of TXA in reduction mammaplasty and abdominoplasty. Using data from the TriNetX LLC (Cambridge, MA) National Health Research Network database, this retrospective study compared adult patients undergoing reduction mammaplasty or abdominoplasty who received intraoperative IV TXA against those who did not. Primary outcomes included postoperative seroma and hematoma incidences, whereas secondary outcomes assessed the necessity for procedural drainage and the occurrence of VTE within 1-year postsurgery. No significant differences in the rates or risks of hematoma, seroma, or the need for procedural drainage between patients administered IV TXA and those who were not, for both reduction mammaplasty and abdominoplasty. Additionally, IV TXA did not increase the risk of VTE in either patient group. IV TXA application in reduction mammaplasty and abdominoplasty does not provide added benefits in reducing postoperative complications such as seroma, hematoma, or the necessity for procedural drainage. Furthermore, it does not alter the risk of thromboembolic events. These findings highlight the need for further research, particularly through randomized control trials, to understand TXA's efficacy in plastic surgery.
