The objective of this study is to develop a topical bead formulation of tranexamic acid (TA) which can be used concomitantly with laser treatment. The bead formulation of TA (TAB) was successfully prepared by fluidized bed drying method. Physicochemical properties of the TAB were evaluated in terms of chemical stability of TA and differential scanning calorimetry. TA in the bead was stable up to six months at 25 °C and existed as amorphous state. In vitro skin permeation and in vivo skin retention of TA in the beads were significantly higher compared to a commercial product...

Tranexamic acid (TA) is widely used by orthopedic surgeons to decrease blood loss and the need for transfusion following total hip arthroplasty (THA). Although both intravenous and topical applications are described in the literature, there remains no consensus regarding the optimal regimen, dosage and method of delivery of TA during THA. In addition, concerns still exist regarding the risk of thromboembolic events with intravenous administration. The purpose of this meta-analysis was to compare the efficacy and safety of topical versus intravenous administration of TA in THA...

BACKGROUND: Intra-articular injection of tranexamic acid (TXA) is known to be effective in controlling blood loss after total knee arthroplasty (TKA). However, this method has some disadvantages, such as TXA leakage due to soft tissue release. Peri-articular injection provides an alternative to intra-articular administration of TXA. This study aimed to evaluate the effects of peri-articular injection of TXA in reducing blood loss after TKA and compare them to those of intra-articular TXA injection...

INTRODUCTION: The current Tactical Combat Casualty Care Guidelines recommend tranexamic acid (TXA) administration for casualties in whom massive blood transfusion is anticipated. However, despite Hextend being the recommended resuscitation fluid, the guidelines recommend against using TXA with Hextend. This appears to be due to a concern about pharmaceutical compatibility, despite the absence of a direct study of compatibility in the literature. METHODS: Two solutions of Hextend and TXA were examined for compatibility...

Spine surgery has been growing rapidly as a neurosurgical operation, with an increase of 220% over a 15-year period. Intraoperative blood transfusion is a major outcome determinant of spine procedures. Various approaches, including pharmacologic and nonpharmacologic therapies, have been tested to decrease both intraoperative and postoperative blood loss. The aim of this systematic review is to report clinical evidence on the relationship between intraoperative blood loss (primary outcome) and on transfusion requirements and postoperative complications (secondary outcomes) in patients undergoing spine surgery...

Non-variceal upper gastrointestinal bleeding, the most common etiology of which is peptic ulcer disease, remains a persistent challenge despite a reduction in both its incidence and mortality. Both pharmacologic and endoscopic techniques have been developed to achieve hemostasis, with varying degrees of success. Among the pharmacologic therapies, proton pump inhibitors remain the mainstay of treatment, as they reduce the risk of rebleeding and requirement for recurrent endoscopic evaluation. Tranexamic acid, a derivative of the amino acid lysine, is an antifibrinolytic agent whose role requires further investigation before application...

BACKGROUND: Tranexamic acid (TXA) is an antifibrinolytic drug widely used to reduce blood loss during joint replacements, including total knee arthroplasty (TKA) and total hip arthroplasty (THA). However, there is no final consensus regarding the composition of an optimal administration of TXA regime between topical and systemic (intravenous). The purpose of our study was to compare the efficacy of topical and intravenous (IV) regimen of TXA during TKA and THA. METHODS: Five relevant electronic online databases, PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science and Chinese Biomedical Database were systematically searched in November 2015...

Seizures following cardiopulmonary bypass are an immediate and alarming indication that a neurologic event has occurred. A case report of a 67-year-old man undergoing aortic valve surgery who unexpectedly experiences seizures following cardiopulmonary bypass is outlined. Possible contributing factors including atheromatous disease in the aorta, low cerebral perfusion pressures, an open-chamber procedure, and the use of tranexamic acid are identified.

BACKGROUND: Hyperfibrinolysis (HF) is a major contributor to coagulopathy and mortality in trauma patients. This study investigated (i) the rate of HF during the pre-hospital management of patients with multiple injuries and (ii) the effects of pre-hospital tranexamic acid (TxA) administration on the coagulation system. METHODS: From 27 trauma patients with pre-hospital an estimated injury severity score (ISS) ≥16 points blood was obtained at the scene and on admission to the emergency department (ED)...

Trauma is a leading cause of death and disability worldwide, in civilian environments and on the battlefield. Trauma-induced haemorrhage is the principal cause of potentially preventable death, which is generally attributable to a combination of vascular injury and coagulopathy. Survival rates following severe traumatic injury have increased due to advanced trauma management initiatives and treatment protocols, influenced by lessons learned from recent conflicts in Iraq and Afghanistan. The use of tourniquets and intraosseous needles, early blood and blood product transfusion, administration of tranexamic acid in pre-hospital settings, and consultant-led damage control resuscitation incorporating damage control surgery have all played their part...

PURPOSE: To clarify if blood loss and transfusion requirements can be decreased in revision knee surgery through a multimodal blood loss approach with tranexamic acid (TXA). PATIENTS AND METHODS: A retrospective study was designed in 87 knees (79 patients) that received a knee revision between 2007 and 2013. To avoid heterogeneity in the surgical technique, only revisions with one single implant system were included. A treatment series of 44 knees that received TXA and other techniques in a multimodal blood loss protocol was compared to a control series of 43 knees that received neither TXA nor the rest of the multimodal blood loss protocol...

BACKGROUND: The efficacy of tranexamic acid (TXA) in reducing blood loss and transfusion requirements in total hip and knee arthroplasty has been well established in small controlled clinical trials and meta-analyses. The purpose of the current study was to determine the risks and benefits of TXA use in routine orthopaedic surgical practice on the basis of data from a large, statewide arthroplasty registry. METHODS: From April 18, 2013, to September 30, 2014, there were 23,236 primary total knee arthroplasty cases and 11,489 primary total hip arthroplasty cases completed and registered in the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI)...

The purpose of this study was to evaluate the efficacy and safety profiles of topical tranexamic acid (TXA) in patients undergoing elective total knee arthroplasty (TKA) with comorbid conditions precluding them from intravenous (IV) TXA use. A total of 104 patients were divided into two groups: 47 in the normal-risk group and 57 in the high-risk group, with the latter representing those with one or more risk factors for venous thromboembolism (VTE). Demographics were similar between groups, and there were no differences with regard to postoperative changes in hemoglobin (- 3...

Multiple studies have shown tranexamic acid (TXA) to reduce blood loss and transfusion rates in patients undergoing total knee arthroplasty (TKA). Accordingly, TXA has become a routine blood conservation agent for TKA. In contrast, ε-aminocaproic acid (EACA), a similar acting antifibrinolytic to TXA, has been less frequently used. This study evaluated whether EACA is as efficacious as TXA in reducing postoperative blood transfusion rates and compared the cost per surgery between agents. A multicenter retrospective chart review of elective unilateral TKA from April 2012 through December 2014 was performed...
