Filter by:Researchers are testing a more accurate way to measure how much fluid is in the lungs (also called pulmonary edema, or "increased lung water") in people with Heart Failure (HF) using MRI (Magnetic Resonance Imaging). There is little known about the exact level of lung water in patients with AHF or how these levels change from the time of hospital admission to discharge. The purpose of this research study is to measure the lung water in patients hospitalized for HF, to determine the change in lung water over the course of hospitalization and treatment, and to find out if lung water levels can predict if patients are higher or lower risk for returning to the hospital or dying from heart failure.
The use of thoracic ultrasound has expanded widely within the las couple of years, and several studies have proved a high diagnostic accuracy for many of the most common causes of respiratory failure and dyspnoea. The ultrasound scan is a bed-side, and dynamic examination, which demands sufficient theoretical and practical knowledge and competence by the operator, but so far, no studies have explored the effect of simulation-based training for gaining adequate competence compared to traditional hands-on training on healthy figurants. The aim of this study is to examine whether TUS training on a simulator is superior to training on healthy figurants. Secondly, to examine whether the choice of hands-on training has an effect on the number of examinations performed by the trainees from baseline to 4 months follow-up.
Burn injury leads to hypovolemic then distributive shock. Fluid resuscitation remains the cornerstone of initial treatment of burn shock. However, fluid rescucitation can lead to fluid overload, which manifests most notably as lung edema. The peptide NT-pro-BNP, a biomarker of cardiac congestion secreted by the myocardium, as well as plasma CD146, an endothelial factor involved in angiogenesis and a marker of vascular congestion, may help identifying patients with risk of pulmonary edema and hypoxia . Our hypothesis is that these biomarkers may predict the occurence of pulmonary edema in severe burns patients.
The purpose of this study is to determine whether high flow nasal oxygen (HFNO) therapy is non inferior to non invasive ventilation (NIV) in the immediate treatment of patients with acute hypercapnic cardiogenic pulmonary edema associated with respiratory failure in the emergency department.
Critical patients in emergency room are seriously situations that need quickly diagnosis and treatment. Different predictors of prognosis can be related with mortality and morbidity in-hospital and in long-term. In Brazil, this kind of registry is not available. The aim of the study is analysis and report data about critical patients in Emergency Departments over all country, showing demographic, clinical and prognosis data about that in Brazil.
The purpose of this study is to determine whether Non Invasive Ventilation are effective in prevention of reperfusion pulmonary edema after pulmonary artery angioplasty. Our hypothesis is that administration of Non Invasive Ventilation during the procedure and systematically in post procedure period is a protective factor against the development and severity of reperfusion pulmonary edema.
This project will study the use of ultrasound of the chest for the detection of fluid in the lungs in patients with pre-eclampsia vs pregnant patients without pre-eclampsia. Pre-eclampsia is a syndrome usually diagnosed in the second half of pregnancy in which patients develop elevated blood pressure and may develop protein in their urine, neurologic abnormalities, fluid in the lungs, and abnormal blood tests associated with the liver and kidney. Pulmonary edema (fluid in the lungs) in pre-eclampsia can lead to patient discomfort and significant morbidity and mortality. It can be detected using chest x-ray, although this type of imaging offers significant disadvantages, including radiation, which is of particular concern in pregnant patients. In addition, previous studies have demonstrated that chest x-ray is not very accurate in the detection of fluid in the lungs. Multiple previous studies have demonstrated the utility of chest ultrasonography in detecting fluid in the chest, although the vast majority of these studies involved patients with acute decompensated heart failure. Our goal is to evaluate bedside ultrasound of the chest in patients with pre-eclampsia in comparison to normal pregnant patients to determine whether these patients have abnormal fluid in the chest. The investigators will divide our patients into two groups. In the study group, the investigators will include patients with pre-eclampsia with or without shortness of breath, and in the control group, the investigators will include pregnant patients without pre-eclampsia. Informed consent will be obtained from all patients enrolled in the study. These patients will then undergo an ultrasound of the chest, performed by a member of the Emergency Medicine Ultrasound Division. The images will be transmitted wirelessly from the ultrasound machine to a secure web based cloud (Q-path) and will be subsequently reviewed by expert reviewers.
The aim of the study is to determine the feasibility of collecting respiratory parameters during recompensation following ADHF (Acute Decompensated Heart Failure)with non-invasive measurements. This could lead to a better understanding of how respiratory parameters may change during re-compensation therapy and could also be a comfortable method for patients.
The need for fluid resuscitation (FR) in ICU patients with acute respiratory distress syndrome (ARDS) is common. Indeed, relative or absolute hypovolemia is a common phenomenon that the intensivist must recognize early and treat promptly. Fluid challenge may have adverse side effects associated with fluid administration. The diffusion within the interstitial space may favor edema formation and cause cardiac dysfunction by volume overload. Edema formation is global and may specifically alter pulmonary alveolar epithelial integrity, leading to enhanced alveolar edema and impaired gas exchange. Currently, two types of fluids are frequently used, crystalloids and colloids. Among colloids and compared to crystalloids, albumin has the theoretical advantage of causing greater volume expansion. We hypothesized that a fluid resuscitation therapy with albumin generates less pulmonary edema than a fluid resuscitation therapy with crystalloids. The aim of our study is to compare alveolar fluid clearance, as a marker of alveolar edema fluid resorption, in 2 groups of patients: those treated with albumin and those treated with crystalloid.
We use a new technology (Nexfin from BMEYE-Inventive Hemodynamics) to monitor Cardiac Output, Blood Pressure, Fluid Responsiveness, Pulse Oximetry, Hemoglobin Concentration, Oxygen Delivery in Climbers during their process of acclimatization on a expedition to Mount Aconcagua.
