In this study, a simple, fast, accurate and sensitive spectrophotometric method has been developed for the determination of tranexamic acid in bulk and pharmaceutical preparations. The method is based on the reaction of ninhydrin with the primary amino group of tranexamic acid in the basic medium at pH 8.0. The reaction produces a bluish-purple color which absorbs maximally at 565 nm. Beer's la...
A 16-year-old woman with craniofacial injury developed severe acute respiratory failure under the primary reconstructive surgical procedure requiring several units of blood and plasma. A transfusion related acute lung injury (TRALI) was suspected and supportive treatment was initiated. Because of the severity of symptoms, acute extracorporeal membrane oxygenation (ECMO) was planned. During prep...
IMPORTANCE Excessive bleeding and transfusion increase morbidity and mortality in patients receiving coronary artery bypass grafting (CABG), especially in those exposed to antiplatelet agents. OBJECTIVE To evaluate the influence and interaction of clopidogrel bisulfate and tranexamic acid on bleeding and transfusion outcomes. DESIGN A multicenter randomized and blinded trial. SETTING Seve...
OBJECTIVE The effectiveness and safety of aprotinin use in cardiac surgery have been questioned. More data reflecting everyday clinical practice from large-scale, unselected populations are needed. We compared the effectiveness and safety of aprotinin in cardiac surgery with those of tranexamic acid in a follow-up study using the population-based Danish health-care databases. METHODS We ident...
Background: Heavy menstrual bleeding is a leading cause of poor quality of life and iron deficiency anemia in reproductive aged women. The aim of this study was to compare the efficacy and acceptability of Medroxyprogestrone acetate and Tranexamic acid in menorrhagia management. Materials and Methods: Inclusion criteria were: age 20-45 years, regular menses, not using hormonal drugs for previou...
INTRODUCTION Patient blood management strategies for total hip and knee arthroplasty are controversial. They range from pre-operative haemoglobin optimisation to intra- and post-operative interventions. The aim of this study was to assess the various treatment modalities with respect to blood loss, haemoglobin levels and blood transfusions. METHODS The analysis was based on the principles of ...
Treatment of a haemorrhagic shock after just a single dose of fondaparinux in an orthopaedic patient with reduced renal clearance is presented. Since all routine haemostatic parameters were nearly normal, single doses of rFVIIa (90 microg/kg) and of tranexamic acid (15 mg/kg) were administered to improve thrombin generation and reduce fibrinolysis. This case is the first showing the effectivene...
BACKGROUND Total knee arthroplasty (TKA) is associated with a significant blood loss. Several methods have been reported to reduce postoperative blood loss and avoid homologous blood transfusions. In this study, we investigated the efficacy of temporary clamping of the drain either or not in combination with tranexamic acid administration for controlling blood loss after TKA. METHODS The pros...
BACKGROUND Neonates undergoing open-heart surgery are particularly at risk of postoperative bleeding requiring blood transfusion. Aprotinin has attained high efficacy in reducing the requirement for a blood transfusion following a cardiopulmonary bypass, but is seldom studied in the neonatal age group. The aim of this study was to compare the efficacy and adverse effects of aprotinin and tranex...
INTRODUCTION Blood loss during and after total knee arthroplasty (TKA) can lead to substantial morbidity and the need for blood transfusions. There are several methods to minimize blood loss and to decrease transfusion rates in patients undergoing TKA. Tranexamic acid is an antifibrinolytic agent with known efficacy for achieving these goals. Currently, many surgeons are performing TKA without ...
