Filter by:Blood transfusion is at the heart of the therapeutic arsenal when there is a hemorrhage and/or blood loss during a surgery. There are two types of transfusion: the homologous one (blood from a compatible donor) and the autologous or autotransfusion method (which is done with the patient's own blood). Although homologous transfusions can save lives, it can cause significant adverse events. Since then, multiple solutions have been developed to avoid exposing patients to these risks. It is in this context that was born the "Patient Blood Management" (PBM). Thus, the strategy in this PBM has been defined as "the appropriate use of blood and blood components, with the aim of minimizing the use of allogeneic transfusions". In this context, particular interest has been given to autologous transfusion or autotransfusion or cell salvage, the general purpose is to reduce (or even stop) the use of allogeneic products and to reduce the risks associated with the ABO compatibility system, as well as all the adverse effects associated with allogeneic plasma and platelet transfusions. Most autotransfusers available on the market operate by centrifugation. Autotransfusion is already a solution in Patient Blood Management and its efficiency and safety have already been optimized. However, there is still a need to improve the quality of the treated blood with an easier-to-use device that could improve the quality of the blood concentrate. Indeed, with the current devices, it may happen that the use of allogeneic transfusions, plasma and platelets transfusions, is necessary in addition to autologous red blood cells thus reducing the interest of autotransfusion. It is in this context that i-SEP has developed a new autotransfusion device based on a filtration method. Unlike competing devices, the i-SEP device allows the concentration of not only red blood cells (as competitive devices) but also platelets. In this study, the i-SEP device is used in typical clinical applications of autotransfusion: cardiovascular and orthopedic surgeries, where there is a risk of hemorrhage and/or blood loss for example ≥ 500mL in cardiac surgery and ≥ 300mL in orthopedic surgery. The study includes a screening phase (≤ 21Days), surgery phase when the i-SEP device is used (Day 0), a post-surgery phase (Day 1 - Day 6), a first follow-up visit (Day 7 ± 3) and a second follow-up visit (Day 30 ± 7).
This randomised controlled trial has a non-inferiority design. The aim is to test if the blood loss (volume in mL and hemoglobin) is effected by heart and lung cardiotomy retransfusion, or not? Forty CABG (Coronary Artery By pass Grafting) patients will be allocated to either receive retransfusion (n=20) of cardiotomy blood via the heart and lung mashine, or no retransfusion (n=20).
A phase 3 multicenter unblinded randomized controlled trial comparing the temporary uterine blood supply occlusion with conventional approach during laparoscopic myomectomy in patients with uterine leiomyoma.
Although, suction drainage is routinely used in orthopedic clinical practice, there are still no precise guidelines on its use in total joint arthroplasty, particularly in total as well as unicompartmental knee arthroplasty. In fact, drain use is likely associated to an increased risk of blood transfusion due to the lack of tamponade effect, as well as a higher infection rate. Furthermore, the drain itself could interfere with knee mobilization, delaying its functional recovery. Thus, the aim of this study was to investigate the real usefulness of suction drainage in perioperative bleeding control in the management of total as well as unicompartmental knee arthroplasty.
Liver transplantation is the standard treatment for chronic advanced liver disease, whether or not associated with a primary liver tumor. The intraoperative bleeding and the need for blood transfusion, encountered in this major surgery are associated with increased morbidity and mortality. However, this hemorrhagic risk has been drastically reduced in the last 20 years and liver transplants without the use of blood products are now possible. Indeed, improvements in medical and surgical techniques associated with a better understanding of the pathophysiology of the cirrhotic patient have enabled this advance. One of the targeted therapeutic strategies is the control of portal hypertension. Several treatments have been sought, such as the use of splanchnic vasoconstrictors (such as vasopressin) and hypovolemic phlebotomy. These techniques reduce portal pressure and seem to reduce intraoperative bleeding with, even, a protective effect on kidney function. Their single-use or their combination is currently used in certain centers of expertise in liver transplantation. However, the hemodynamic effects of the combination of these 2 treatments on portal pressure has never been demonstrated. In this study, the effect of vasopressin, combined with a hypovolemic phlebotomy, on portal pressure in cirrhotic patients undergoing liver transplantation will be evaluated.
The purpose of this investigation is to determine the most effective regimen of administration of tranexamic acid to improve clinical outcome among patients undergoing total knee arthroplasty.
In patients with coronary artery disease, dual antiplatelet therapy (acetylsalicylic acid and a P2Y12-receptor antagonist) is a commonly used method because of its excellent antithrombotic effect. In particular, in patients with acute myocardial infarction, who receive coronary angiography as an emergency, the dual antiplatelet is used immediately before the test to prevent and test further clot formation, regardless of whether or not the patient had previously taken dual antiplatelet. Ticagrelor, a direct-acting and reversible ADP receptor antagonist, was introduced in Denmark in 2013 and is now the most commonly used ADP receptor antagonist in the treatment of ACS. Compared to its predecessor clopidogrel, the pharmacokinetic profil of ticagrelor is more predictable, demonstrating a faster onset of action and a more consistent platelet inhibition. However, because of the excellent antithrombotic effect and increased bleeding potential, it is recommended that major bleeding, such as OPCAB or CABG surgery, be expected with a high probability, and in case of fatal surgery, the drug should be discontinued for 5 days. Most patients who receive emergency coronary heart surgery after undergoing coronary angiography as an emergency due to an acute myocardial infarction, it take approximately 24-48 hours to undergo surgery after examination. In fact, there have been reports of large-scale cross-country studies that do not increase bleeding risk compared to 5 days until 3 days after ticagrelor is stopped. Therefore, this study aimed to retrospectively analyze the bleeding tendency by analyzing the records of patients using clopidogrel or ticagrelor in preoperative coronary angiography for patients undergoing emergency CABG surgery from 2016 to September 2019.
Blood loss during a surgical procedure is inevitable, its reduction is a key factor for surgical success. Also, to avoid progress to severe complications like hemodynamic decompensation, cardiac arrest or the need to blood transfusions. According to the Center for Disease Control (CDC), there is a usage of more than 17 million transfused blood products units per year. Blood transfusion is a convenient technique for reposition of blood during major bleed, but it involves several probable complications like anaphylaxis, bloodborne infections and others. Consequently, meticulous hemostasis during surgery is crucial to diminish blood loss. Hemostatic agents play a pivotal role during surgical time. Amongst them topical, energy-based and systemic agents are the vast majority. Tranexamic acid (TXA) is a lysine synthetic derivate that inhibits fibrinolysis by blocking the 5 lysine-binding sites to plasminogen. It has been used in clinical practice since 1962 and become very popular after 2010 when the CRASH-2 study showed a decreased risk of death in trauma patients. Tranexamic acid use is widely extended among diverse surgical fields: orthopedics, cardiac surgery and obstetrics. In plastic surgery it uses is limited mainly to craniofacial surgery as a local agent. The aim of this trial is to show the efficacy of tranexamic acid as hemostatic agent in liposuction and to compare its efficacy among different administration routes.
