Filter by:Hip fractures are associated with a large hidden blood loss. That is, the total blood loss associated with hip fracture surgery is much greater than that observed intra operatively. There is currently no viable method of identifying patients at risk of transfusion. The on admission haemoglobin level has been shown to be falsely reassuring . We are conducting a study of 200 consecutive hip fracture patients. Thrombelastography (TEG) is taken on admission. The results are blinded to clinicians. Results will be evaluated at the end of the study, comparing intra-operative and total blood losses with the TEG profile of the patient.
Purpose: Examine oral and intravenous Tranexamic Acid (TXA) to determine whether or not the different routes of drug administration are equivalent in terms of post-operative reduction in hemoglobin, number of transfusions, and post-operative blood loss following TJA surgery. Hypothesis: Oral and intravenous TXA are equivalent routes of drug administration.
The main hypothesis of this clinical trial is that the use of intra-articular tranexamic acid and the fibrin glue plus usual hemostasis will reduce at least a 25% the postoperative blood loss with respect to usual hemostasis in patients undergoing subcapital femoral fractures.
We will investigate the efficacy and safety of using tranexamic acid by intravenous, intra-articular and combinational administration to reduce blood loss during total knee replacement. We hypothesize a combined intra-articular and single intravenous dose protocol of tranexamic acid may achieve a higher therapeutic concentration at the intra-articular and extra-articular bleeding site with little or no systemic absorption and subsequent systemic side effects.
Using of surgical blade may have less blood loss than unipolar electrocautery in Total Knee Arthroplasty (TKA).
Currently, there is very little research to identify ways to decrease blood loss during D&E (dilation and evacuation) procedures. The objective is to determine whether routine use of intravenous oxytocin will improve bleeding outcomes at the time of D&E at 18-24-weeks gestation. To evaluate the hypothesis, investigators will perform a randomized, double-blinded, placebo-controlled trial. The patient will be followed until discharged from the postoperative care unit during which time patient satisfaction, pain score and postoperative bleeding will be assessed.

The purpose of this study is to determine the relative effectiveness of two drug agents, Tranexamic acid (TXA) and aminocaproic acid (Amicar), that act through a similar mechanism of action. These agents are used to decrease blood loss that is a result of major surgery, like total joint arthroplasty. A secondary goal will be investigate the cost-analysis of total hospitalization. Both TXA and Amicar are both currently used in the care of patients undergoing total joint arthroplasty. Subjects will be randomly assigned to the TXA or Amicar arm. All data needed for this study including blood loss, need for transfusion, preoperative and lowest postoperative hematocrit and hemoglobin, and complications will be collected during the hospitalization stay. Our Hypothesis is that TXA and Amicar will have similar effectiveness in preventing intraoperative blood loss and the need for transfusion post-op than Amicar. A detailed cost analysis will show that the overall cost of performing the operative procedure, including transfusions, OR time, and total costs associated with admission cost will be more decreased with Amicar as compared to TXA.
It remains still unclear whether topical tranexamic acid has an added value besides the administration of intravenously tranexamic acid. We hypothesize that the addition of topical tranexamic acid, besides intravenous administration of tranexamic acid, results in a 25% reduction of post-operative blood loss after cardiac surgery. The aim of this study is to determine whether the application of topical tranexamic acid reduces the 12 hours postoperative blood loss by 25% in patient scheduled for cardiac surgery on cardiopulmonary bypass, whereby intravenous tranexamic acid is administrated. Just before sternal closure, 250 subjects receives pericardial lavage with 2 gr tranexamic acid in 200 ml normothermic saline solution (NaCl 0.9%), 250 subjects receives pericardial lavage with 200 ml normothermic saline solution without TA and 250 subjects (control group) receives no pericardial lavage. The main study parameter is 12 hours post-operative blood loss and is assessed by 12 hours post-operative chest tube production.
The main objective is to evaluate the efficacy and safety of topical Tranexamic Acid (TA) to reduce the blood transfusion rate in total knee arthroplasty. The secondary endpoints are to estimate the visible blood loss at 24 hours after surgery, and invisible blood loss through serial counting of Hb/Htc. Methodology. TRANEX1 is a phase III, unicentric, controlled, randomized, double blind clinical trial that compare efficacy and safety of topical TA versus intravenous TA in a multimodal protocol, with no-inferiority criteria(n=79).
