Filter by:This is a compassionate use, proof of concept, phase IIb, prospective, interventional, pilot study in which the investigators will evaluate the effects of compassionate-use treatment with IV tirofiban 25 mcg/kg, associated with acetylsalicylic acid IV, clopidogrel PO and fondaparinux 2.5 mg s/c, in patients affected by severe respiratory failure in Covid-19 associated pneumonia who underwent treatment with continuous positive airway pressure (CPAP).
This study is being conducted to assess the effectiveness of intermediate versus prophylactic doses of anticoagulation (blood thinners) in patients critically ill with COVID-19 in the intensive care units (ICUs) throughout the hospital. Anticoagulation is part of the patient's usual standard of care but determining the dose of anticoagulation is based on physician preference. The investigators are conducting this study (a randomized trial with adaptive design employing cluster randomization) with the support of all of the ICUs to collect data in order to determine what should be the standard of care in terms of anticoagulation in these critically ill patients. The patients care will not be altered other than the choice of anticoagulation (both approved and used throughout the hospital as standard of care) based on the ICU bed they are assigned. Patient data will be collected until discharge.
The coronavirus disease of 2019 (COVID-19) is a viral illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), now deemed a pandemic by the World Health Organization. Some COVID-19 patients may develop coagulopathy which is associated with poor prognosis and high risk of thrombosis. Some patients develop severe thrombotic complications, such as pulmonary embolism, despite anti-thrombotic prophylaxis by low molecular weight heparin. The aim of this project is to evaluate modified thromboelastometry for identifying patients at high risk of thrombosis. The hypothesize is that hypofibrinolysis with increased plasma PAI-1, TAFI (thrombin-activatable fibrinolysis inhibitor ) levels in association with high thrombin generation may explain high incidence of thrombosis in this population. A simple laboratory assay, widely available in hospitals, such as thromboelastometry, might be of great clinical interest to detect Covid-19 patients with high risk of thrombosis. In order to make ROTEM more sensitive to hypofibrinolysis, exogenous t-PA will be added in the assay. The preliminary results showed that patients with Covid-19 have significant hypercoagulability detectable with ROTEM and Covid-19 patients with thrombosis have both hypercoagulability and hypofibrinolysis.
The main objective of the study is to determine the incidence of deep vein thromboses at Doppler echo in patients with SARS-Cov-2 pneumopathy upon their entry into ICU and after 7 days of hospitalization in ICU. This is a monocentric interventional study (RIPH 2).
The purpose of this study is to evaluate the safety, dose-requirements, and exploratory efficacy of twice-daily subcutaneous enoxaparin as venous thromboembolism prophylaxis in children (birth to 18 years) hospitalized with signs and/or symptoms of SARS-CoV-2 infection (i.e., COVID-19).
Assessment of short-term outcomes of radical nephrectomy combined with IVC thrombectomy with a novel technique without thoracotomy: single center case series.
Digital Variance Angiography (DVA) is a new tool in medical imaging with proven image quality reserve. The previously observed quality reserve of Digital Variance Angiography (DVA) in lower extremity angiographies, allowed to lower radiation exposure by 70 % during DSA in lower extremity diagnostic angiographies with non-inferior image quality. The aim of this study is to apply this non-inferior image quality and use it for radiation exposure reduction in diagnostic lower limb angiography. The project would prospectively block-randomise (50:50) patients, who undergo elective diagnostic angiography into two groups: a comparator group examined by means of conventional DSA using a standard care protocol (Siemens Artis Zee, Extremities Care setting, 1.2 µGy/frame) (Group B) and a study group examined by means of DVA using a low-dose protocol (0.36 µGy/frame corresponding to 70% decrease of radiation dose) (Group A). During each procedure the investigators record radiation exposure (cumulative dosage, dose area product) and contrast media usage and procedural time then compare the results of the groups. Qualitative image review is done to compare conventional DSA and reduced radiation exposure DVA images after image acquisition. Our hypothesis is that with the previously proven non-inferior image quality, the investigators will be able to reduce radiation exposure of the participants and also staff members in everyday clinical practice.
Venous thromboembolism (VTE) is an important cause of morbidity and mortality following surgery.A combination of chemical and mechanical prophylaxis using lower extremity compression devices (CD) is recommended in patients who are considered at 'moderate risk' (Caprini score 2 - 4) or 'high risk' (Caprini score > 4) of developing VTE. The aim of this study was to determine whether upper extremity (UE) CD are as effective as lower extremity (LE) CD in preventing VTE following surgery. A total of 106 patients were recruited.
Venous thrombosis of the upper limb is one of the manifestations of venous thromboembolic disease. The epidemiology and management of upper limb venous thrombosis is much less well documented than that of lower limb venous thrombosis. The investigators wished to provide epidemiological data concerning upper limb venous thrombosis in the hospital setting. The researchers would like to know the prevalence of this pathology among patients hospitalized in a university hospital center. In order to obtain this prevalence, the investigators wish to carry out a monocentric cross-sectional descriptive study.
The aim of this study is to investigate the prevalence and possible risk factors of the occurrence of a DVT in 12 intubated and mechanically ventilated COVID-19 patients admitted to the ICU at a single time point (29/03/2020).
