Abstract Objectives: To test feasibility of a randomized controlled trial (RCT) with an endpoint of time at goal anticoagulation in children on extracorporeal membrane oxygenation (ECMO) randomized to receive bivalirudin..
Read MoreAbstract Background Drug shortages are a frequent challenge in current clinical practice. Certain drugs (e.g., protamine) lack alternatives, and inadequate supplies can limit access to services. Conventional protamine dosing uses..
Read MoreAbstract Background Unfractionated heparin, administered during venoarterial extracorporeal membrane oxygenation to prevent thromboembolic events, largely depends on plasma antithrombin for its antithrombotic effects. Decreased heparin responsiveness seems frequent on extracorporeal..
Read MoreAbstract Background: Patients maintained on extracorporeal membrane oxygenation (ECMO) often require systemic anticoagulation to prevent circuit clotting and systemic thromboembolic complications. The optimal intensity of anticoagulation to balance the risk..
Read MoreAbstract Recent studies suggest that heparan sulfate proteoglycans (HSPG) contribute to the predisposition to, protection from, and potential treatment and prevention of Alzheimer’s disease (AD). Here, we used electronic health..
Read MoreAbstract Case Report A 56-year-old male with a medical history significant for coronary artery disease complicated by non-ST segment elevation myocardial infarction in 2011 (at which time he received a..
Read MoreAbstract Background Heparin is used for anticoagulation during cardiopulmonary bypass. After weaning from bypass, protamine is administered to neutralize the effects of heparin and thus reestablish hemostasis. Rotational thrombelastometry has..
Read MoreAbstract Bleeding and thrombotic complications are major drivers in extracorporeal life support (ECLS) patients’ negative outcomes and are reported in up to 40% of the ECLS-runs [1, 2]. Consumptive coagulopathy..
Read MoreAbstract Background Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Syndrome is a severe adverse drug reaction marked by delayed hypersensitivity reactions causing skin and systemic complications. DRESS diagnosis is..
Read MoreAbstract Introduction Over the past decade, there has been an increase in the use of recombinant Anti-Thrombin III (AT-III) administration during neonatal and pediatric short- and long-term mechanical support for..
Read MoreAbstract Heparins have been invaluable therapeutic anticoagulant polysaccharides for over a century, whether used as unfractionated heparin or as low molecular weight heparin (LMWH) derivatives. However, heparin production by extraction..
Read MoreAbstract Background: The conventional method of heparin and protamine management during cardiopulmonary bypass (CPB) is based on total body weight which fails to account for the heterogeneous response to heparin in each patient...
Read MoreAbstract Background The presence of dextran sulfate (DS) in reagents and the type of blood collection tube (citrate/citrated-theophylline-adenosine-dipyridamole [CTAD]) can lead to discrepancies between unfractionated heparin (UFH) anti-Xa levels. Objectives ..
Read MoreAbstract Background No guidelines for administering and monitoring anticoagulants intraprocedurally are currently available in dogs, despite the prevalence of procedures necessitating systemic anticoagulation with heparin. Objectives To evaluate an activated..
Read MoreAbstract Introduction Individualized heparin and protamine management is increasingly used as a strategy to reduce coagulation activation and bleeding complications. While it is associated with increased heparin requirements during Cardiopulmonary..
Read MoreAbstract Extracorporeal membrane oxygenation (ECMO) supplies circulatory support and gas exchange to critically ill patients. Despite the use of systemic anticoagulation, blood exposure to ECMO surfaces causes thromboembolism complications. Inhibition..
Read MoreAbstract Objectives We aimed to evaluate thrombotic and hemorrhagic complications with heparin versus bivalirudin use in veno-venous extracorporeal membrane oxygenation (V-V ECMO). Methods We performed a retrospective cohort study of..
Read MoreAbstract The term heparin resistance (HR) is used by clinicians without specific criteria. We performed a literature search and surveyed our SSC membership to better define the term when applied..
Read MoreAbstract Background Little evidence exists on the relationship between the estimated heparin sensitivity index (HSI) based on commonly available clinical and laboratory data and observed HSI in the adult population...
Read MoreAbstract Introduction There are several types of surface treatments (coatings) aimed at improving the biocompatibility of cardiopulmonary bypass (CPB) circuit. Some coatings appear to require higher doses of heparin to..
Read MoreAbstract Heparin-induced thrombocytopenia (HIT) is an immune-mediated from unfractionated or low-molecular-weight heparin that results in thrombocytopenia and potentially catastrophic thrombosis. HIT occurs due to the development of platelet-activating antibodies against multimolecular..
Read MoreAbstract Background: Systemic anticoagulation with heparin during cardiopulmonary bypass (CPB) should be neutralized by protamine administration to restore normal hemostasis. Our previous study showed the protamine-to-heparin ratio (P-to-H) of 1:1..
Read MoreAbstract Objective To retrospectively evaluate a conservation approach to heparin reversal implemented during times of critical shortages. This approach was aimed at maintaining access to cardiac surgical services. Setting In-patient hospital..
Read MoreAbstract Objective Heparin resistance is often encountered during cardiopulmonary bypass. Heparin dose and activated clotting time target values for the initiation of cardiopulmonary bypass are not yet universally standardized; further..
Read MoreAbstract Background: Postoperative atrial fibrillation (POAF) is defined as new-onset AF in the immediate postoperative period. The relatively high incidence of POAF after cardiac surgery is well described, but pathophysiological..
Read MoreAbstract Introduction Off-pump coronary artery bypass grafting (OPCABG) was introduced many years ago aiming to reduce the known complications of conventional on-pump coronary surgeries. Heparin is required during the procedures,..
Read MoreAbstract The common conception of “heparin rebound” invokes heparin returning to circulation in the after apparently adequate intraoperative reversal with . This is believed to portend increased and provides the rationale for administering..
Read MoreAbstract Objectives In our center, an unusual rate of patients had abnormalities of hemostasis in immediate postoperative period of cardiac surgery. Our objectives were to identify the cause of these..
Read MoreAbstract Heparin anticoagulation increases the bleeding risk during extracorporeal life support (ECLS). This study determined whether factor XII (FXII) silencing using short interfering RNA (siRNA) can provide ECLS circuit anticoagulation without bleeding. Adult..
Read MoreAbstract Introduction There are no randomized controlled trials comparing low and high activated partial thromboplastin time (aPTT) targets in heparinized adult veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) patients. Our systematic..
