Filter by:The purpose of this study is to determine the effectiveness of infrared thermal imaging in adjunctive diagnostic screening for lower limb deep venous thrombosis (DVT).
To assess the real-world safety/effectiveness of Eliquis in Korean venous thromboembolism (VTE) patients and patient characteristics that are associated with bleeding among patients taking Eliquis. To identify factors that might be associated with the safety and effectiveness profile in Korean VTE patients.
To evaluate the pharmacokinetics of thromboprophylactic doses of LMWH enoxaparin in postoperative CABG patients, drug is administered either as a continuous intravenous infusion (CIV) or subcutaneous bolus (SCB) once per 72h. Plasma anti-Xa values are measured 12-14 times during study period and concentration maximums calculated to enable comparison of anti-Xa values between administration routes.
To assess the safety and descriptive efficacy of apixaban in pediatric subjects requiring anticoagulation for the treatment of a VTE.
The aim of this study is to evaluate the frequencey and the determinants of postpartum major complications (hemorrhage and thrombosis) up to 3 months after delivery in the maternity hospitals of Finistère (Bretagne - France)
Until now there ist no systematic investigation of the pharmacokinetic parameters of Rivaroxaban in obese patient undergoing bariatric surgery. The aim of this study is to investigate the pharmacokinetic and pharmacodynamic parameters of rivaroxaban in obese patients before and after bariatric surgery. Patients receive the day before the surgical intervention the first dose of Rivaroxaban (10mg). During the following 24 hours, 9 blood samples are taken. The second tablet Rivaroxaban is administered on the third postoperative day, followed again by 9 blood samples during the next 24 hours. All other blood samples are taken independent from this clinical trial as part of the standard medical treatment during the hospitalization. The hospital stay will not be extended by the study. The outpatient regular follow-up takes place one month after surgery and is combined with the last study visit.
This is a pilot study to determine if anti-thrombin III (AT-III) serum concentrations differ between patients with normal versus subtherapeutic anti-Xa trough concentrations when placed on enoxaparin 30 mg twice daily for VTE prophylaxis. Secondarily, this study will compare two enoxaparin dosing strategies.
Venous thromboembolism (VTE) is a leading cause of death among hospitalized patients, and is an important patient safety issue in plastic surgery. Previous work has shown that enoxaparin prophylaxis can prevent many post-operative VTE events, and current American Society of Plastic Surgeons guidelines support enoxaparin prophylaxis for high-risk patients. Highest risk patients often have cancer or trauma reconstruction. Primary outcomes include 1) peak and trough steady-state aFXa levels in response to standard and escalated doses of enoxaparin and 2) the proportion of patients with appropriate aFXa levels pre and post initiation of a clinical protocol for enoxaparin dose adjustment. The investigators expect that standard dosing will result in inadequate aFXa peak and trough levels, and that the clinical dose adjustment protocol will significantly improve the proportion of in-range aFXa levels. The investigators will also develop a linear regression-based equation to calculate, based on patient-level factors, the required dose of enoxaparin to generate in-range aFXa levels. This research may show that the current "one size fits all" approach to enoxaparin prophylaxis is insufficient. In the trauma and orthopaedic populations, patients with low initial aFXa levels are significantly more likely to develop deep venous thrombosis. Thus, this study has important implications for appropriate enoxaparin dose magnitude and frequency, and may ultimately help to decrease the substantial morbidity and mortality associated with post-operative VTE.
Patients with cancer hospitalized for an acute medical illness have an increased risk of venous thromboembolic events. Although international guidelines suggest the use of thromboprophylaxis in these patients, the recommendations are based on studies which included a percentage of patients with cancer without primarily focusing on this high risk group. Since patients with cancer present an increased risk of bleeding complications it is critical to evaluate the safety of thromboprophylaxis in the cancer group. Recent studies suggest a limited use of thromboprophylaxis in these patients. The aim of this study is to evaluate the use, efficacy and safety of thromboprophylaxis in medical cancer patients hospitalized for an acute medical disease. Design: observational, prospective study Primary end-point: incidence of major and clinically relevant non major bleeding during hospitalization Secondary endpoints: frequency of use, doses and contraindications for pharmacological thromboprophylaxis; venous thromboembolic events up to three months after discharge
The investigators have recently developed a registry of missed doses of VTE prophylaxis that includes retrospective data on missed doses of VTE prophylaxis. To decrease rates of VTE prophylaxis refusal, the group has developed a patient-centered education bundle that will be delivered as an in-person, 1-on-1 discussion session with a nurse educator. Supporting education materials include a 2-page education sheet and an educational video. The investigators hypothesize that patient refusal of VTE prophylaxis is associated with significant knowledge gaps among patients regarding patients' risk of developing VTE and the benefits of VTE prophylaxis and that delivering an education bundle to patients that refuse VTE prophylaxis will improve compliance with VTE prophylaxis and decrease rates of VTE.
