Tranexamic acid is a medication used to treat or prevent excessive blood loss during surgery. Previous studies have shown tranexamic acid (TXA) reduces blood loss and post-operative blood transfusion rate without significant complications. In addition, many meta-analyses have confirmed these results. This study also aims to determine how safe and effective tranexamic acid treatment is for different patients undergoing primary total knee arthroplasty.
The investigators aimed to compare two doses of intravenous (IV) tranexamic acid (TXA) with a combined single dose of topical and IV TXA on haemoglobin decline 24 hours after total joint arthroplasties. The investigators conducted randomized, double-blind trial. The participants were randomized to either intrvenous group receiving 2 doses of 1 gram TXA in intravenous route 3 hours apart, or a combined application group receiving the first 1 gram IV and the topical dose was 1.5 gram after reduction of the fascia.
Tranexamic acid has been used to reduce bleeding and transfusion for years. Randomized studies showed its efficacity in orthopedic surgery, trauma and post-partum hemorrhage. Few data were available for other types of surgery and the safety profile of tranexamic use was nor clearly established. In april 2022, the results from the POISE-3 (Perioperative Ischemic Evaluation - 3) trial was published in the New England Journal of Medicine. This stdy clearly demonstrated in 9535 patients undergoing non-cardiac surgery, that the use of tranexamic acid significantly reduced not only perioperative bleeding, but also transfusions. The safety profile of tranexamic acid was very good in this trial. This publication was rapidly followed by editorials in major anesthesia journals, calling for "safe surgery" with a systematic use of tranexamic acid in the population studied in the POISE-3 trial. A literature review was done with a formal presentation at Erasme University Hospital, again with the call for a systematic use in appropriate patients. In this study, the adherence to these recommendations will be tested. All patients operated between october 1st 2022 and december 31 st 2022 will be included. For every patient, it will be determined if this patient should have received tranexamic acid according to the results of the POISE-3 trial and wether this patient really did get tranexamic acid. Primary endpoint will be the percentage (%) of patients correctly treated according to the POISE-3 recommendations. A second primary endpoint will be the comparison with patients operated between October 1st 2021 and december 31st 2021; that means before the publication of the recommendations. The difference between both populations will be tested with a Chi-square test. Secondary outcomes wil be bleeding and transfusion in the correctly treated population compared with an eventually not correctly treated population.
Introduction and Aim In the intraoperative or postoperative period of hip replacement surgeries, approximately 46% of patients receive erythrocyte transfusion. 'Patient blood management' protocols have been established in order to reduce the frequency of perioperative surgical bleeding and transfusion. The aim of this study is to evaluate the patients who underwent hip replacement by the same experienced surgeon; to evaluate retrospectively in terms of patient characteristics, surgical and anesthesia management, blood transfusion frequency. Methods The characteristics of patients who underwent hip replacement (total hip replacement, revision hip replacement, partial hip replacement) operation by the same experienced surgeon between 2010-2022 at Baskent University after the approval of Baskent University Medical and Health Sciences Research Board, results will be analyzed retrospectively through perioperative follow-up forms and review of patient files. Expectations and scientific contributions Preparing patients for surgery, determining the causes of blood loss during and after surgery and creating preventive strategies are important for all operations, especially hip replacement surgeries. While determining the strategies, the main aim should be to see the pre-, intra- and post-operative period as a whole, to determine the transfusion risks according to the comorbidities and anemia of the patients, and to determine the anesthesia and analgesia managements that reduce blood loss in the intraoperative and postoperative periods.
The transfusion risk and clinical knowledge (TRACK) allogeneic blood transfusion prediction model was developed more than ten years ago and demonstrated good discriminative ability in patients with increased risk for allogeneic blood transfusion in an all Italian population. At the time of derivation, dual anti-platelet medication was suggested in the treatment of acute coronary syndrome, but not yet fully implemented. The aim of this study is to externally validate the TRACK blood transfusion prediction model in the cardiac surgery population of Medisch Spectrum Twente Thoraxcentrum Twente. Additionally, the impact of adding the preoperative use of dual anti-platelet medication, as additional predictive factor, to the TRACK blood transfusion prediction model will be investigated.
This study aimed to develop and interpret a machine learning model to predict red blood cell (RBC) transfusion.
This study compares the effect of three different dose levels of tranexamic acid（TXA）in reducing blood loss and transfusion requirements in cardiac valve surgery.
Blood Banks of large medical centers have large annual budgets, typically millions of dollars. Blood product wastage results in not only in a loss of the product's cost, but also of the fees involved in transporting, handling, and administering these products. Optimal utilization of blood products requires a balance between maximizing patient clinical outcomes while avoiding unnecessary costs and risks associated with transfusions. This project will specifically focus on packed red blood cell transfusions (pRBCs). There are clear guidelines for transfusing pRBCs however these guidelines are not always followed. pRBC transfusions outside of recommended guidelines is associated with increased risk of harm to patients. Our aim is to improve adherence to guideline indicated pRBC transfusions for patient in the UCHealth system thereby decreasing inappropriate (non-guideline indicated) pRBC transfusions. We will conduct a QI project seeking to improve pRBC transfusion guideline adherence. This project will involve data review to establish baseline rates, multimodal interventions to improve adherence to pRBC transfusion guidelines including provider education, modifications to the electronic ordering interface, and changing blood back policies at participating institutions.
Blood transfusion is common for patients in hospital, especially for those in intensive care. Patients receive blood that is matched to them based on their blood group (A, B, AB, O), but not based on sex. This means male or female patients may receive male or female blood. There is some evidence to suggest that giving male patients female blood and female patients male blood (sex-mismatched blood) may be harmful. The investigators think giving males only male blood and females only female blood (sex-matched blood) will be better for the patients and improve their survival. To test this, the study team will randomly give 50% of intensive care patients who require blood only sex-mismatched blood and 50% of intensive care patients only sex-matched blood for their entire hospital stay. Then, health data of patients will be collected to see if either group does better after transfusion. Before this is done as a large study with thousands of patients, it will be attempted as a smaller pilot study with a few hundred patients to be sure the processes suggested make sense and are possible for hospitals and for the blood supplier to follow.
