Filter by: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.
The aim of the work is to compare the efficacy of preoperative IV tranexamic acid and rectal misoprostol in reducing blood loss in the elective cesarean section. Research question: In women undergoing elective cesarean section, is preoperative administration of IV tranexamic acid better than rectal misoprostol in reducing blood loss?
In obstetrics, postpartum haemorrhage (PPH) continues to be a major contributor to maternal morbidity and mortality worldwide. Uterine atony is the most common cause of PPH, and the prophylactic use of uterotonics, specifically oxytocin, is the standard of care for PPH prophylaxis. It is believed that tranexamic acid (TXA) can enhance the hemostatic process further by inhibiting the fibrinolytic system. TXA is an antifibrinolytic that has been studied in many different patient population for its use in reducing blood loss ranging from gynaecological and non gynaecological surgeries, to trauma patients. It has been found to reduce mortality in treatment of patients with PPH, and recent evidence have found promising results in its use for prophylaxis of PPH.
Postpartum hemorrhage and its complications are very well known causes for maternal mortality .Uterine atony is the most common cause for postpartum hemorrhage
Purpose: The study aimed to determine whether intravenous administration of tanexamic acid (TXA) before shoulder arthroscopic rotator cuff repair surgery can improve arthroscopy visual clarity. Methods: This is a prospective, double-blinded, randomized and placebo-controlled study. From May 2016 to April 2018, patients requiring arthroscopic rotator cuff repair were enrolled and randomly assigned to either the TXA group that received 1000mg tranexamic acid intravenously 10 minutes before surgery or the placebo group that received the same volume of plain saline. Patients with pre-existing liver/renal disease, coagulopathy, or concurrent use of anti-coagulation medications were excluded. The visual clarity was rated by a numeric rating scale from grade 1(poor) to grade 3(clear) every 15 minutes throughout the surgery. Secondary outcomes included estimated perioperative blood loss, operative time, degree of shoulder swelling, postoperative subjective pain score, inpatient duration and associated comorbidities were recorded. Both parametric and nonparametric methods were used for statistical analysis.
Total hip arthroplasty (THA) is associated with blood loss ranging from 300 to 2000 mL. Tranexamic acid (TXA) is frequently administered prophylactically during this procedure to reduce blood loss by inhibiting fibrinolysis or by stopping naturally occurring clot resolution. TXA is employed currently based on a surgeon's preference. The objective of this study is to quantitate the degree of fibrinolysis using rotational thromboelastometry (ROTEM) and investigate the role of TXA prophylaxis on blood loss in patients undergoing THA in a double-blind fashion. Our hypothesis is that fibrinolysis is minimal at most and TXA prophylaxis is not necessary during THA. All patients, whether they receive TXA or normal saline, will not be at risk, as at this time no data exists to determine which approach is safer or more effective. This is the first study to compare TXA vs. placebo in a double-blinded, randomized controlled trial.
TXA is currently administered pre-hospital in Canada, Germany, United Kingdom and Israel . These studies demonstrated that TXA use did not result in any detectable complications or adverse events. It is considered an ideal pre-hospital treatment because: (a) patients with severe hemorrhage die early more often than patients without hemorrhage; (b) it seems that the earlier treatment is administered, the better; (c) it is stable and easily stored; and (d) it is easily administered by paramedics. Herein, the study aimed to evaluate the effect of administration of second dose of Tranexamic acid infusion in the hospital setting in comparison to not receiving the second dose on the outcomes of trauma patients with an evidence of significant hemorrhage. Recently, HGH ambulance service has included pre-hospital administration of TXA in trauma patients with significant hemorrhage. So, all eligible trauma patients will receive pre-hospital TXA (first dose) slowly over 10 minutes by the critical care paramedics as standard of care. Inclusion Criteria: All adult trauma male and female patients (≥18 or <90 years) with evidence of significant hemorrhage (systolic blood pressure <90 mmHg or heart rate >110 beats per minutes, or both) or had Capillary Refill Time 3-4 seconds and received first dose of prehospital TXA will be included in the study. Exclusion criteria: 1. Age > 90 or < 18 years of age 2. Inability to obtain intravenous access (intraosseous access not sufficient) 3. Documented cervical cord injury with motor deficit 4. Known prisoner 5. Known pregnancy 6. Traumatic arrest with > 5 minutes CPR without return of vital signs 7. Penetrating cranial injury 8. Traumatic brain injury with brain matter exposed 9. Isolated drowning or hanging victims 10. Wearing an opt out bracelet. Patient data will include demographics, time since injury, type of injury (blunt or penetrating), Glasgow Coma Score(GCS), Injury severity score (ISS), systolic blood pressure, respiratory rate, central capillary refill time, estimated number of hours since injury, laboratory findings, blood transfusion, units of transfused blood, management, complications and outcome. The primary outcome will be death in hospital within 4 weeks of injury. Secondary outcomes will be morbidity (thromboembolic events, sepsis, Acute respiratory distress syndrome and organ failure), and number of blood transfusions (Massive transfusion protocol) and hospital length of stay.
Aim of this study is evaluate whether superior nasal compression with tranexamic acid to simple nasal compression and Merocel packing. In this study, patients who presented with non-traumatic anterior epistaxis to emergency departments will be included in this study. Three different therapy option are created; first, nasal compression with tranexamic acid, second, simple nasal compression without any drugs. And third, packing with Merocel.
Excision and grafting in burn patients can lead to severe blood loss. A preliminary study conducted in Saint Joseph Saint Luc Hospital showed that the total median blood loss was 1412 mL (1). Transfused patients had a total median blood loss of 2468 mL and an average number of 4 packed red blood cells (PRBC) administered. Among the various methods that help limit blood loss, tranexamic acid, which has been proved useful in traumatology and surgery, has not been sufficiently studied in burn patients. A preliminary study in 27 burned patients showed a reduction of blood loss with tranexamic acid (2). Objective of TRANBURN study is to demonstrate that tranexamic acid help limit blood loss and reduces the use of blood products.
Upper gastrointestinal hemorrhage is a frequently diagnosis in emergency departments. Although new drugs and endoscopic techniques were easily applied in various settings in this condition, the role of local administered therapies such as antifibrinolytic agents remain unclear. The investigators aimed to compare standard therapy (proton pump inhibitors, endoscopic treatments etc.) and standard therapy + local administered tranexamic acid in upper gastrointestinal hemorrhage in a double-blind, randomized trial.
