Abstract The use of extracorporeal membrane oxygenation (ECMO) for acute cardiac and/or respiratory failure has grown exponentially in the past several decades. Systemic anticoagulation is a fundamental element of caring..
Read MoreAbstract Known limitations of unfractionated heparin (UFH) have encouraged the evaluation of anticoagulant aptamers as alternatives to UFH in highly procoagulant settings such as cardiopulmonary bypass (CPB). Despite progress, these..
Read MoreAbstract Extracorporeal membrane oxygenation (ECMO) contributes to coagulopathy, necessitating systemic anticoagulation to prevent thrombosis. Traditionally, unfractionated heparin (UFH) has been the anticoagulant of choice, however, due to many inadequacies new evidence suggests..
Read MoreAbstract Introduction: The Activated Clotting Time (ACT) is commonly used to manage anticoagulation during cardiac surgery. The aim of this study was to compare the older manually operated Hemochron® Response and..
Read MoreAbstract OBJECTIVES: A significant proportion of patients with coronavirus disease 2019 requiring venovenous extracorporeal membrane oxygenation at our institution demonstrated heparin resistance, which in combination with a heparin shortage resulted..
Read MoreAbstract Heparin resistance is suspected when more heparin than usual is needed to achieve a therapeutic range of activated partial-thromboplastin time. Management may include increasing the heparin dose, supplementing antithrombin..
Read MoreAbstract BACKGROUND: Heparin-induced thrombocytopenia (HIT) is an immune-mediated adverse reaction to heparin. Patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) are routinely anticoagulated with heparin before the initiation of bypass...
Read MoreAbstract Protamine is mainly used to reverse the anticoagulant effect of heparin after cardiopulmonary bypass (CPB). Unfortunately, it is associated with adverse clinical reactions ranging from minor cardiopulmonary instability to..
Read MoreAbstract Background Heparin-induced thrombocytopenia (HIT) is an immune-mediated reaction to heparin that provokes a prothrombotic state and causes a decline in platelet count. Data describing outcomes of HIT after cardiac..
Read MoreAbstract Heparin has served as a mainstream for over eight decades. Clinically heparin-derived compounds significantly contribute to prevention and treatment of thrombotic events complicated in numerous medical conditions such as , and processes. Moreover..
Read MoreAbstract Extracorporeal membrane oxygenation (ECMO) is often used in the management of COVID-19-related severe respiratory failure. We report the first case of a patient with COVID-19-related ARDS on ECMO support..
Read MoreAbstract BACKGROUND: The standardized management of anticoagulation during the cardiopulmonary bypass seems inaccurate because of patients and surgeries variability. This study evaluates if an individualized management of heparin and protamine..
Read MoreAbstract Heparin is the earliest and most widely used anticoagulant and antithrombotic drug that is still used in a variety of clinical indications. Since it was discovered in 1916, after..
Read MoreAbstract Background and Objectives Heparin-induced thrombocytopenia (HIT) is an antibody-mediated condition that leads to thrombocytopenia and possible thrombosis. Patients with HIT who require cardiac surgery pose a challenge as high..
Read MoreAbstract Coagulation factor XII (fXII) is a plasma serine protease which belongs to the contact activation complex responsible for initiating the intrinsic coagulation pathway. fXII deficiency is a rare congenital..
Read MoreAbstract Background Diagnosis of heparin-induced thrombocytopenia (HIT) requires pre-test probability assessment and dedicated laboratory assays. Objective To develop a pre-test score for HIT. Design Observational; analysis of prospectively collected data..
Read MoreAbstract Extracorporeal membrane oxygenation (ECMO) bridge to lung transplantation (LuTX) exposes the patients to a high risk of perioperative bleeding secondary to systemic anticoagulation and coagulation factors deficiency. With this..
Read MoreAbstract Background: Heparin is the widely used anti-coagulation strategy for patients on extracorporeal membrane oxygenation (ECMO). Nevertheless, heparin-induced thrombocytopenia (HIT) and acquired anti-thrombin (AT) deficiency preclude the use of heparin..
Read MorePreamble Guidelines summarize and evaluate available evidence with the aim of assisting health professionals in proposing the best management strategies for an individual patient with a given condition. Guidelines and..
Read MoreAbstract Heparin-induced thrombocytopenia is an immune-mediated disorder caused by antibodies that recognize complexes of platelet factor 4 and heparin. Thrombosis is a central and unpredictable feature of this syndrome. Despite..
Read MoreAbstract The interaction between the patient and the ECMO (extracorporeal membrane oxygenation) circuit initiates a significant coagulation and inflammatory response due to the large surface area of foreign material contained..
Read MoreAbstract Cardiopulmonary support is frequently required during lung transplantation. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has been recently shown to be an acceptable and, perhaps, safer alternative to cardiopulmonary bypass machine..
Read MoreAbstract Background Extracorporeal cardiopulmonary resuscitation (ECPR) is being used increasingly in the emergency and critical care field in Japan. A major complication of ECPR is bleeding; however, the optimal initial..
Read MoreAbstract Heparin-induced thrombocytopenia type II (HIT) is a rare but potentially fatal antibody-mediated reaction to all forms of heparin (unfractionated heparin, low-molecular weight heparin, heparin flushes, and heparin-coated catheters), which..
Read MoreAbstract OBJECTIVES: The three direct oral anticoagulants (DOACs) dabigatran, apixaban and rivaroxaban are now widely used in clinical practice. For patients requiring perioperative interruption of DOACs, heparin bridging is still..
Read MoreAbstract Coronary artery bypass grafting surgery (CABG) in hemophilia patients is challenging. Thromboelastography (TEG) is useful to assess hemostasis perioperatively. A patient with severe hemophilia A underwent CABG with TEG studies...
Read MoreAbstract Introduction: This manuscript represents a pilot study assessing the feasibility of a single-compartment, individualised, pharmacokinetic algorithm for protamine dosing after cardiopulmonary bypass. Methods: A pilot cohort study in a..
Read MoreAbstract Background: We sought to determine whether the introduction of a new anticoagulation protocol improved the frequency with which target anticoagulation parameters were met in children supported with extracorporeal membrane..
Read MoreAbstract Background: Sonoclot is used to measure kaolin-based activated clotting time (kACT) for heparin management. Apart from measuring kACT, the device assesses the patient’s coagulation status by glass bead–activated tests..
Read MoreAbstract The study by Grieshaber and colleagues, “Platelet-activating protamine-heparin-antibodies lead to higher protamine demand in patients undergoing cardiac surgery,” in this issue of the Journal, is a prospective study that joins other..
