Abstract
PURPOSE OF REVIEW Tranexamic acid (TXA) has emerged as a promising pharmacological adjunct to treat and prevent postpartum hemorrhage (PPH). We provide an overview of TXA, including its pharmacology, key findings of randomized trials and observational studies, and critical patient safety information. RECENT FINDINGS Pharmacokinetic data indicate that TXA infusions result in peak plasma concentration within 3 min (range: 1-6.6 min). Ex-vivo pharmacodynamic data suggest that low-dose TXA (5 mg/kg) inhibits maximum lysis for at least 1 h. In predominantly developing countries, TXA has demonstrated a 19% reduction in the risk of bleeding-related death among patients with PPH. Based on high-quality randomized trials, TXA prophylaxis does not effectively reduce the risk of PPH during vaginal delivery and is likely ineffective in reducing the PPH risk during cesarean delivery. TXA exposure does not increase the risk of maternal thrombotic events. Maternal deaths have occurred from accidental intrathecal TXA injection from look-alike medication errors. SUMMARY TXA has shown promise as an important adjunct for PPH treatment, especially in low-resource settings. However, TXA is not recommended as PPH prophylaxis during vaginal or cesarean delivery. Patient safety initiatives should be prioritized to prevent maternal death from accidental intrathecal TXA injection.

Abstract
Tranexamic acid is a well-known antifibrinolytic that has numerous clinical indications, and it is efficacious and safe in many perioperative scenarios including patients with some thrombotic risks. However, further studies that characterize clinical outcomes concerning dosing, timing, and routes in combination are needed in ultra high-risk populations.

Abstract
Several factors have been identified as contributing to medication administration errors, including look-alike, sound-alike (LASA) errors. LASA errors are important causes of serious adverse events arising from spinal injection of tranexamic acid, which can be confused with ampoules of local anaesthesia.We present a case of accidental injection of 250 mg of tranexamic acid rather than prilocaine during spinal anaesthesia. The patient developed lower extremities myoclonus, followed by generalised convulsions and ventricular fibrillation, that was reverted within 6 min. Severe cardiogenic shock requiring both inotropic and vasopressor therapy followed, along with a classic apical ballooning pattern on echocardiography and elevated myocardial injury markers, indicating Takotsubo cardiomyopathy. The patient's condition progressively improved to full recovery, and she was discharged from hospital after 1 month with no neurological deficit or cardiac dysfunction.To our knowledge, this is the 28th reported case of accidental spinal injection of tranexamic acid. We present a brief review of previously published cases.

Abstract
We conducted a narrative review in six areas of obstetric emergencies: category-1 caesarean section; difficult and failed airway; massive obstetric haemorrhage; hypertensive crisis; emergencies related to neuraxial anaesthesia; and maternal cardiac arrest. These areas represent significant research published within the last five years, with emphasis on large multicentre randomised trials, national or international practice guidelines and recommendations from major professional societies. Key topics discussed: prevention and management of failed neuraxial technique; role of high-flow nasal oxygenation and choice of neuromuscular drug in obstetric patients; prevention of accidental awareness during general anaesthesia; management of the difficult and failed obstetric airway; current perspectives on the use of tranexamic acid, fibrinogen concentrate and cell salvage; guidance on neuraxial placement in a thrombocytopenic obstetric patient; management of neuraxial drug errors, local anaesthetic systemic toxicity and unusually prolonged neuraxial block regression; and extracorporeal membrane oxygenation use in maternal cardiac arrest.

Abstract
Tranexamic acid (TXA) is a potent antifibrinolytic with documented efficacy in reducing blood loss and allogeneic red blood cell transfusion in several clinical settings. With a growing emphasis on patient blood management, TXA has become an integral aspect of perioperative blood conservation strategies. While clinical applications of TXA in the perioperative period are expanding, routine use in select clinical scenarios should be supported by evidence for efficacy. Furthermore, questions regarding optimal dosing without increased risk of adverse events such as thrombosis or seizures should be answered. Therefore, ongoing investigations into TXA utilization in cardiac surgery, obstetrics, acute trauma, orthopedic surgery, neurosurgery, pediatric surgery, and other perioperative settings continue. The aim of this review is to provide an update on the current applications and limitations of TXA use in the perioperative period.

Abstract
PURPOSE In this Continuing Professional Development module, we review the practical pharmacology of tranexamic acid and its clinical use in trauma, obstetrics, and major orthopedic surgery. PRINCIPAL FINDINGS Tranexamic acid is a synthetic drug that inhibits fibrinolysis. Multiple clinical trials in various clinical settings have shown that it can reduce blood loss, transfusion rates, and bleeding-associated mortality. In trauma and obstetrical bleeding, early tranexamic acid administration (< three hours) may have greater clinical benefits. Overall, tranexamic acid use appears safe with no significant increase of thromboembolic or seizure events. Nevertheless, current evidence has limitations related to wide heterogeneity in dose, route, and timing of drug administration, as well as generalizability of the large-scale trial findings to higher income nations. CONCLUSIONS Tranexamic acid is an efficacious and safe pharmacological-based blood conservation technique in the management of clinically significant hemorrhage. All anesthesiologists should have a good understanding of the pharmacotherapeutic properties and perioperative role of tranexamic acid therapy both inside and outside of the operating room. The use of tranexamic acid is likely to continue to rise with endorsement by various clinical guidelines and healthcare organizations. Further quantitative research is needed to evaluate optimal dosing and drug efficacy in these clinical scenarios.

Abstract
Tranexamic acid has been increasingly used due to its safety and effectiveness. It has been associated with multiple reported cases of errors due to lack of attention, incorrect labeling of the syringes, or look-alike with other medications leading to the incorrect route of injection and the associated catastrophic sequela. Here we report a case of wrong route injection of tranexamic acid during spinal anesthesia, leading to myoclonic seizures and eventually intensive care unit admission of a patient undergoing orthopedic surgery. It is reported that higher doses of tranexamic acid would cause massive sympathetic discharge as evidenced by the initial hypertensive response reported in our case report and also in some repeated patient. Tranexamic acid induced seizures either from direct cerebral ischemia secondary to decreases in regional or global or from neuronal hyperexcitability by blockage of inhibitory cortical-gamma aminobutyric acid (GABA)-A receptors. Some evidence has been shown for dose-related neurotoxicity in the animal model, with greater severity and duration of seizure with increasing doses.
