Filter by:Objectives: To investigate the role of thromboelastography parameters (R, K, Angle, MA) in monitoring anticoagulation in maintenance hemodialysis (MHD) patients. Subjects: Two hundred stable MHD patients. Methods: An observational study. Primary outcome: Relationship between thromboelastography parameter R Value and coagulation of hemodialysis circuit and dialyzer. Secondary outcome: Relationship between thromboelastography parameters (K Value, Angle and MA) and coagulation of hemodialysis circuit and dialyzer.
Coronary endarterectomy (CE) combined with coronary artery bypass grafting (CABG) can be the final option for achieving complete revascularization in diffuse coronary artery disease patients. Since the exposure of subendothelial tissue to the blood flow after CE, the coagulation cascade can be activated, resulting in the increased risk of graft failure. Therefore, anticoagulation with warfarin in this group of patients might be beneficial. However, evidence is limited. This study aims to compare the clinical outcomes between dual antiplatelet therapy with or without warfarin after CE+CABG.
The purpose of this study was to compare the efficacy and safety of nafamostat mesylate and unfractionated heparin during ECMO anticoagulation in critically ill patients.
A novel Coronavirus (COVID-19) infection leading to pneumonia and severe acute respiratory failure [acute respiratory distress syndrome (ARDS)] and death is a global threat. On 11/03/2020, WHO declared the Covid-19 outbreak a global pandemic. As of 18th of March, there are 202,309 confirmed cases with 8,013 deaths. Patients with severe illness may develop dyspnoea and hypoxemia within 1week after onset, which may quickly progress to ARDS or end-organ failure 1. Based on Chinese data abnormal coagulation parameters (Prolonged Prothrombin time [PT] and raised D dimer) are reported to predict a poor prognosis and may therefore be important therapeutic targets. The number of patients with infected with COVID- 19 in UK is rapidly rising as with many other European countries. Eventually >50% of people will have become infected and COVID-19 will remain a public health threat in the long term. It is therefore very important to understand every aspect of this disease, including the associated coagulopathy leading bleeding, blood clots (thrombosis) and death. Emerging data from Europe and some centres in UK, indicates that venous thromboembolism (VTE), mainly pulmonary embolism (PE), is major problem in COVID patients. In this retrospective-prospective: multicentre study, investigators will document the patient characteristics, presenting haematological parameters and associated comorbidities and their association with bleeding, thrombosis and mortality in patients admitted for hospital treatment. Determining the predictive value of patient characteristics and presenting laboratory measurements for clinical outcomes in these patients will allow us to optimise management of these patients in the future. Furthermore, by comparing these data with data from patients without Covid-19, investigators will be able to modify existing protocols and tailor them to the management of COVID -19.
Short bowel syndrome (SBS) is defined as a loss of function of the small intestine resulting in a malabsorptive disorder. In SBS, oral drug absorption may be altered due to extensive intestinal resection. It remains unclear to what extent apixaban exposure is impacted in SBS.Therefore this study tries to investigate the pharmacokinetics (PK) of apixaban in adult patients with SBS requiring long-term parenteral nutrition (PN).
Prospective assessment of vitamin K dependent coagulation factor levels after temporary warfarin reversal in participants with left ventricular assist devices (LAVD).
The aim of our study is to assess three anticoagulation strategies for intermittent hemodialysis(IHD) in patients at risk of hemorrhage. A registry of consecutive hemodialysis patients with high risk of hemorrhage was conducted at the Guangdong General Hospital, the First Affiliated Hospital of Guangzhou University of Chinese Medicine, the Second Affiliated Hospital of Guangzhou Medicine University or Guangzhou Hospital of Chinese Medicine, between Sep 10, 2017 and June 30th,2018. In this multi-center prospective and randomized study, participants were randomly divided into three groups during IHD according to different anticoagulation, including with regular saline flushes, one stage regional citrate anticoagulation (RCA) and two-stage RCA.
Spinal canal anesthesia is marked the most commonly used method of cesarean section. Traditional spinal anesthesia may cause post-dural puncture headache and low back pain.Plenty of parturients are undergoing anticoagulation therapy.They may be forced to accept general anesthesia in order to avoid epidural hematoma.Therefore, we propose minimally invasive spinal anesthesia.
The aim of this study is to investigate the clinical significance of high INR (International Normalized Ratio) values (>9) in VKA (vitamin K antagonist) treated patients with atrial fibrillation. The clinical characteristics of these patients will be studied as well as the clinical presentation. Factors influencing on high INR values will be recorded and the aim is to seek out patients who have elevated risk of bleeding complications.
Clonidin works as a presynaptic agonist of alpha-sympathomimetic receptors of the brain but also in many other tissues. It is part of balanced anesthesia in general anesthesiology as well as a sedastive agent in intensive care units, but also serves as a third-line agent in many psychiatric diseases including ADHD, schizophrenia and PTSD. The investigators want to show whether clonidin has an procoagulatoric effect on thrombozytes of patients under double anticoagulaotirc treatment with ASS and clopidogrel. The investigators will use a flowcytometric assay to determine activation of thrombozytes when they come into contact with clonidine in vitro as well as Multiplate analyses to determine activation of thrombozytes, either thrombin.induced aggregation, ADP-induced aggregation or arachidonic acid-induced aggregation of thrombozytes.
