The Annals of otology, rhinology, and laryngology. 2022;:34894221086086
Abstract
OBJECTIVE Our aim is to evaluate the effect of topical tranexamic acid (TA) on bleeding and surgical quality field in the functional endoscopic sinus surgery (FESS). METHODS A total of 74 patients who underwent FESS due to chronic rhinosinusitis were included. The patients were randomized into 2 groups. TA group (n = 37) received a topical cotton pledget soaked with TA and placebo (PL) group (n = 37) received a pledget soaked with saline solution. RESULTS A significant effect was noted for the TA group versus the PL group in the grade 1 of the Boezaart scale at 35 minutes (4 for TA group and no case for PL group). This effect was absent for higher grades. We did not notice a significant effect between the 2 groups at 5 minutes. Blood loss was 359 ml in the TA group versus 441 ml in the PL group. No significant change was observed between the 2 groups concerning the blood parameters. No side effects were reported. CONCLUSION Despite its safety when administrated locally and its low cost, TA provides limited effect on quality of surgical field after 35 minutes of the start of FESS in the patients with chronic rhinosinusitis. This effect was absent at the start of the intervention and when analyzing the blood loss and hematologic parameters.

Abstract
OBJECTIVE To conduct a systematic review and meta-analysis of all randomized controlled trials (RCTs) that inspected the efficacy and safety of prophylactic TXA compared with control (placebo/no treatment) among women undergoing vaginal delivery on reducing postpartum blood loss and related morbidities. METHODS Six databases were screened from inception until 06-December-2021. The pooled data were summarized as mean difference or risk ratio, respectively, with 95% confidence interval in a fixed- or random-effects model. RESULTS Sixteen studies comprising 17 RCT treatment arms were included. There were 7075 patients; 3548 and 2537 patients were allocated to prophylactic TXA and control groups, respectively. Overall, the included RCTs had a low risk of bias. Prophylactic TXA correlated with a significant decrease in mean postpartum blood loss and mean change in hemoglobin/hematocrit. Moreover, prophylactic TXA was linked to decreased incidence rates of postpartum hemorrhage, need for blood transfusion, and need for additional uterotonic agents. Nevertheless, prophylactic TXA culminated in significantly higher incidence rates of nausea, vomiting, and diarrhea, all of which were well-tolerated. There was no increased risk of thromboembolic events. Leave-one-out sensitivity analysis confirmed the robustness of efficacy endpoints. There was no publication bias for the endpoint of mean postpartum blood loss. CONCLUSION Among patients undergoing vaginal delivery, prophylactic TXA during active management of third stage of labor (AMTSL) appeared largely safe and correlated with a significant decrease in postpartum blood loss and related morbidities compared with control intervention. Prophylactic TXA should be integrated as a "formal" component of AMTSL among women undergoing vaginal delivery.

BMC surgery. 2022;22(1):46
Abstract
BACKGROUND Blood loss and incision-related complications caused by the surgical procedure to release gluteal muscle contracture (GMC) put negative effects on the surgical outcomes. Current procedures to prevent blood loss and complications are not satisfactory. The current study aimed to determine whether tranexamic acid (TXA) in combination with pressure dressing reduce the amount of blood loss, the rate of incision-related complications, and the rate of readmission for patients undergoing surgeries to release GMC. METHODS 49 GMC patients were finally included in the study and were randomly divided into two groups: study group and control group. Patients in both groups received minimally invasive surgery to release GMC except that in the study group, patients were administered a dosage of 20 mg/kg of intravenous TXA preoperatively, and 2 subsequent dosages of TXA at 10 mg/kg at two time points: 3 and 6 h after the first dose. Gauze soaked with TXA was used to pack the wound for 10 min before the incision closure. Then the wound was pressure-wrapped with a hip-spica bandage for 24 h after the surgery in the study group. RESULTS The level of UBL in the study group was significantly lower compared to that in the control group. Similar results were also found for UMHD and UMAD. The incision-related postoperative complications were greatly decreased in the study group compared to those of the control group as well. So was the 30-day readmission rate. All patients in both groups reached "excellent" or "good" level with respect to the postoperative function evaluation. CONCLUSIONS Intravenous and topical application of TXA combined with 24 h pressure hip-spica bandage reduces perioperative blood loss, rate of incision-related complications, and the rate of readmission for GMC patients undergoing minimally invasive surgical releasing procedure.

Abstract
Liposuction remains one of the most frequently performed cosmetic surgical procedures and its popularity is increasing every year. However, since its inception, justified concerns regarding patient safety have placed limits on the volume of fat that can be aspirated, influenced by hemodynamic fluctuations and blood loss during liposuction. Tranexamic acid (TXA) is an antifibrinolytic agent that competitively inhibits the conversion of plasminogen to plasmin, thus preventing the binding and degradation of fibrin. Despite the existence of evidence of the effectiveness of TXA in orthopedic and cardiac surgeries, there is little evidence of its use in liposuction. The objective of this study was to evaluate the efficacy and safety of tranexamic acid in the control of surgical bleeding in patients undergoing liposuction, through a prospective, open, randomized and controlled clinical trial. Two groups of 25 participants each were formed to whom the application of TXA in a tumescent solution prior to liposuction or liposuction with the traditional technique was randomly assigned. The results showed a decrease in blood loss reflected by the differences in the final hematocrit values, as well as decrease in the same per aspirated volume (p = 0.003). No adverse events were found related with the TXA application and no blood transfusions were required in this group, in contrast to the control group where the need for blood transfusion was present in 20% of the intervened participants.

Ferrari FA, Garzon S, Raffaelli R, Cromi A, Casarin J, Ghezzi F, Uccella S, Franchi M
Journal of obstetrics and gynaecology : the journal of the Institute of Obstetrics and Gynaecology. 2022;:1-13
Abstract
Tranexamic acid (TA) has been proposed for preventing or treating primary postpartum haemorrhage (PPH), which is the leading cause of maternal morbidity and mortality worldwide. We conducted a systematic literature search to the TA role in managing PPH in vaginal and caesarean delivery. Twenty-seven randomised controlled trials (RCTs) (33,302 women) were identified. Three RCTs investigated TA for preventing PPH after vaginal delivery and 22 after caesarean section. None demonstrated a preventive effect on secondary clinical outcomes related to blood loss. Two trials evaluated TA for treating PPH after vaginal and caesarean delivery. Only the WOMAN trial showed that 1 g of TA is effective. In conclusion, TA is considered useful and is recommended or advised for treating PPH. Conversely, available evidence on the prophylactic role is still limited, and this use is not supported. Further investigation is recommended. In this regard, stronger and more reliable outcomes than blood loss should be considered.

BMC pregnancy and childbirth. 2022;22(1):178
Abstract
BACKGROUND Postpartum haemorrhage (PPH) is a major cause of maternal morbidity and mortality worldwide. Tranexamic acid (TXA) is a useful drug for prevention of PPH and merits evaluation in Nigeria, where PPH is the leading cause of maternal death (25%) and severe maternal morbidity. This study evaluates the efficacy of TXA in reducing blood loss following vaginal delivery. METHODS This was a double-blind randomized placebo-controlled study on the efficacy and safety of intravenous TXA in reducing blood loss in women undergoing vaginal delivery in a tertiary hospital. Data analysis was conducted with IBM SPSS software (version 20, Chicago II, USA). P-value < 0.05 was considered statistically significant. RESULTS The mean estimated blood loss was lower in TXA compared with the placebo group. (174.87 ± 119.83 ml versus 341.07 ± 67.97 ml respectively; P < 0.0001). PPH (blood loss > 500 ml) was 5.13% in the study arm compared to the control arm 7.14%- risk ratio (RR) 0.71; 95% CI: 0.38-1.79, p = 0.5956]. Additional uterotonics was required more in the control group compared to the treatment group 14(16.67%) versus 3(3.85%), p-value= 0.007. There were no major complications noticed in the treatment group. CONCLUSION This study demonstrated that intravenous administration of TXA reduced blood loss following vaginal delivery. It also reduced the need for additional uterotonics. However, blood loss greater than 500 was not significantly reduced. TRIAL REGISTRATION This trial was registered retrospectively.

Pharmaceutics. 2022;14(3)
Abstract
The aim of this study was to evaluate the population pharmacokinetics of tranexamic acid (TXA) administered intravenously at a single dose of 0.5 or 1 g in parturients undergoing active hemorrhagic cesarean delivery and to evaluate the influence of patient variables on TXA pharmacokinetics. Subjects from three recruiting centers were included in this PK sub-study if randomized in the experimental group (i.v TXA 0.5 g or 1 g over one minute) of the TRACES study. Blood samples and two urinary samples were collected within 6 h after TXA injection. Parametric non-linear mixed-effect modeling (Monolix v2020R1) was computed. The final covariate model building used 315 blood and 117 urinary concentrations from seventy-nine patients. A two-compartment model with a double first-order elimination from the central compartment best described the data. The population estimates of clearance (CL), central volume of distribution (V1), and half-life for a typical 70 kg patient with an estimated renal clearance of 150 mL/min (Cockroft-Gault) were 0.14 L/h, 9.25 L, and 1.8 h. A correlation between estimated creatinine clearance and CL, body weight before pregnancy, and V1 was found and partly explained the PK variability. The final model was internally validated using a 500-run bootstrap. The first population pharmacokinetic model of TXA in active hemorrhagic caesarean section was successfully developed and internally validated.

Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA. 2022
Abstract
PURPOSE Aim of this systematic review was to evaluate the literature regarding the effect of tranexamic acid (TXA) on the outcome after knee osteotomy. METHODS A systematic literature search was carried out in various databases on studies on the use of tranexamic acid in osteotomies around the knee. Primary outcome criterion was the hemoglobin (drop). Secondary outcome criteria were total blood loss, drainage volume, adverse effects such as thromboembolic events, blood transfusions, wound complications and clinical scores. A meta-analysis was performed for quantitative measures. The present study was registered prospectively ( www.crd.york.ac.uk/PROSPERO ; no.: CRD42021229624). RESULTS Seven studies with 584 patients (TXA group: 282 patients, non TXA group: 302 patients) Hemoglobin decrease (1.54 g/dl vs. 2.28 g/dl), blood loss (394.49 ml vs. 595.54 ml) and drainage volume (266.5 ml vs. 359.05 ml) were significantly less in the TXA group compared to the non TXA group. No thromboembolic event was noted in any study. In the non TXA group four blood transfusions were given. Eleven wound complications occurred in the non TXA group in comparison to two wound complications in the TXA group. CONCLUSIONS The results of the present study show that the application of TXA reduces hemoglobin drop, blood loss and drainage volume. These effects could be responsible for the lesser rate of side effects after administration of TXA during knee osteotomy.

Furqan A, Hafeez S, Khan F, Orakzai SH, Nur AN, Khan MA
Cureus. 2022;14(1):e21052
Abstract
Background Total knee replacement (TKR) is an artificial joint surgical procedure that replaces the damaged articular surfaces of the knee joint. Despite several studies on the efficacy of intra-articular and intravenous Tranexamic acid (TX) use in reducing blood loss following TKR, the route of TXA administration is still an ongoing topic of debate. Our study aimed to compare total knee replacement efficacy (hemoglobin level, hematocrit level, hospital stay, and complications) of intra-articular and intravenous tranexamic acid administration. Material and Methods A Prospective study was conducted at the Department of Orthopedics, Shifa International Hospital, Islamabad. The study duration was six months (August 2020 to February 2021). A sample size of 60 patients was calculated using the WHO calculator. Patients were selected through non-probability consecutive sampling. Patients were randomly divided into two groups; Group A was given intraarticular TXA, while group B was given intra-venous TXA following total knee replacement. Patients were followed for 48 hours. Data were analyzed using SPSS version 24. An Independent T-test was applied, and a P value≤0.05 was considered significant. Results A total of 60 patients were included in the study. There were 20 (33.3%) male and female 40 (66.7%). The mean age of patients was 64.4±10.8SD. Post-operative hemoglobin level in group A was 11.09±0.39SD, and in group B was 9.93±1.73SD (p=0.03). Postoperatively, the mean HCT level in group A was 30.53±4.26SD and group B 26.88±5.48SD (p=0.01). Conclusion Intra-articular administration of TXA is more effective than intravenous administration in controlling postoperative blood loss following total knee replacement.

European journal of haematology. 2022
Abstract
OBJECTIVES To conduct a systematic review of tranexamic acid (TXA) and the risk of renal failure from urinary clots in adult patients with hematuria. METHODS A systematic review of Medline, Embase, CENTRAL, www. CLINICAL TRIALS gov and Google Scholar were searched. Randomized control trials (RCTs) and observational studies that assessed the risk of renal failure with use of TXA among adults with hematuria were included. The primary outcome was renal failure due to urinary tract clots with TXA compared to no TXA (or placebo) or comparator. RESULTS We identified three RCTs (N=466 patients) and three retrospective cohort studies (N=220 patients), and a total of 342 patients that had hematuria and received TXA. The patient population of the six studies included medical and surgical patients, with two of the three RCTs comprised of patients undergoing percutaneous nephrolithotomy, and the third RCT comprised of patients undergoing transurethral resection of the prostate. Documentation of renal function before and after TXA administration was documented in only two studies (N= 28 patients), and neither identified worsening renal function in those exposed to TXA. CONCLUSIONS There are limited studies evaluating the risk of renal failure in patients with hematuria who were exposed to TXA, and the available data does not suggest an increased risk.
