View clinical trials related to Blood Loss.
Filter by:Estimated blood loss is an important parameter recognized as a standard practice in anesthesiology and others medical specialties, with relevant clinical and research applications. Currently is no model capable of accurately estimate blood loss. The purpose of this study is to evaluate the accuracy of a novel model.
The purpose of this study is to determine the need for a blood transfusion during surgery and to evaluate the levels of certain proteins in the blood when given tranexamic acid.
To compare intravenous Tranexamic Acid (TXA) versus normal saline placebo to determine whether or not TXA administration reduces blood loss, decrease in hemoglobin, and rate of transfusions following anatomic and reverse total shoulder arthroplasty (TSA) surgeries.
A randomized, double-blind, single-center and controlled study comparing the efficacy and safety of intravenous administration of tranexamic acid to reduce blood loss in simultaneous bilateral total knee arthroplasty.
Tourniquets are still widely used in total knee arthroplasty, but are associated with several adverse effects. Most of previous studies did not randomize the participants so the baseline difference of the patients might have influenced the outcome. Therefore, investigators conducted a randomized controlled trial, in which all the patients received staged bilateral TKA with two different durations of tourniquet use. Investigators aimed to quantify the effect of tourniquet use on reducing blood loss and to evaluate the impact of tourniquet use on functional and clinical outcome.
A randomized, prospective, placebo-controlled study which aims to evaluate the effect of combined intraarticular and intravenous Tranexamic acid on total blood loss following unilateral knee replacement versus only intravenous tranexamic acid.
This study evaluates the efficacy of tranexamic acid versus placebo on perioperative blood loss using two dosage regimens (standard and extended) after a surgery during total hip arthroplasty in patients receiving the novel fast-acting oral anticoagulant rivaroxaban for prophylaxis of thrombosis.
The aim of the study is to determine if the use of iv TXA or Aquamantys system improve the postoperative hemoglobin and hematocrit after primary TKA and what is the effect of the simultaneous use of iv TXA and Aquamantys on the postoperative hemoglobin and hematocrit. The assumption is that the combination of iv TXA and Aquamantys system will enable an improvement in the postoperative hemoglobin and hematocrit equal or larger than the improvement generated by the use of Aquamantys system alone.
Recently, there has been interest in applying tranexamic acid topically before the closure of surgical wounds in total hip replacement. It has the advantages of ease of application, maximum concentration at the site of bleeding, minimising its systematic absorption and, potentially , decline the risks for systematic side-effects 。
Peroperative bleeding has been studied in specific populations exposed to bleeding (i.e. cardiac surgery, orthopedic surgery). Epidemiology of peroperative bleeding and transfusion remain poorly studied in the whole cohort of patients scheduled for surgery remain unknown. The investigators conducted a prospective study in order to examine the incidence, and risk factors associated with peroperative bleeding and transfusion.
