Active clinical trials for "Acute Lung Injury"

To investigate the possible mechanisms of pulmonary and systemic permeability change including cytokine, extravascular lung water index (EVLWI), and oxygenation parameters in patients with sepsis related acute lung injury (ALI)/acute respiratory distress syndrome (ARDS).

Classically lung elastance and transpulmonary pressure are measured from the difference in tidal variations of airway pressure subtracted by tidal variations i esophagus pressure divided by the tidal volume. This requires the presence of a esophageal balloon catheter which is cumbersome and costly. In this study values obtained as described above are compared to values obtained with a new method in which a stepwise increase in positive endexpiratory pressure (PEEP) is performed with a size of the lung volume increase which corresponds to the tidal volume which the patient is ventilated with. The measurements are performed in sedated and mechanically ventilated patients in the intensive care unit.

Study conducted on hospitalized patient in critical ill units in Nancy and Metz to evaluate if early corticosteroid treatment in first seven days after admission improve patients outcome in Acute Respiratory Distress Syndrome secondary to Covid-19 compared to later corticosteroid therapy or no treatment. Also comparison of acquired infection with or without corticosteroid treatment during hospitalisation.

There is little evidence about the mechanical characteristics and muscular function in patients with Acute Respiratory Distress Syndrome (ARDS) at the time of weaning of the mechanical ventilation, as well as the behavior of the mechanical properties, breathing pattern, muscular effort, and gas exchange during a successful and failed spontaneous breathing trial.

OBJETIVES: To research the worsening of respiratory status risk factors after transfusion in spanish critical care units. To determine the incidence of transfusion-related acute lung injury (TRALI) in critically ill patients. To research the morbi-mortality of TRALI.

Ventilator-induced lung injury is a common complication. The latest and most noticeable theory of its pathogenesis is called 'ergotrauma' by Gattinoni in 2016. The theory uses ventilator-imposed 'energy' or 'power' to encompass several known forms of injury-inducing factors such as pressure,volume, flow, rate, etc. However, to quantify power imposed by ventilator is no easy task in clinical practice. So, Gattinoni proposed a mathematical formula for easy power calculation. However, Gattinoni did not compare the difference between various etiologies of acute lung injury. We will enroll 100 patients (50 with acute respiratory distress syndrome and 50 with normal lung). The ventilator-imposed power at various tidal volume (6, 8, 10 ml/Kg) and positive end-expiratory pressure (5, 10 cmH2O) will be calculated by the formula. The area enclosed by hysteresis of pressure-volume curve, and hence the work it implies, will be measured as a standard. Our study will aim to compare the formula in different patient groups and in Taiwanese people.

This is a longitudinal, multi-center, observational study collecting diverse biological measurements and clinical and epidemiological data for the purpose of enabling a greater understanding of the onset of severe outcomes, primarily acute respiratory distress syndrome (ARDS) and/or mortality, in patients presenting to the hospital with suspicion or diagnosis of COVID-19. We seek to understand whether there are early signatures that predict progression to ARDS, mortality, and/or other comorbid conditions. The duration of the study participation is approximately 3 months.

Acute respiratory insufficiency is one of the principal causes of intensive care admission for COVID 19 positive patients. This may determine a variable mortality rate ranging from 25-30%. In these patients, many days of non-invasive or invasive mechanical ventilation are needed to correct severe hypoxemia. Mechanical ventilation is not a direct therapy but allows the clinicians to prolong the "time-to-recovery" interval necessary for COVID 19 respiratory insufficiency treatment. Long intensive care stay, mechanical ventilation, the use of steroids and sedatives have an impact on the survivors. Previous studies demonstrated that patients admitted to intensive care with non-COVID acute respiratory distress syndrome had a reduction in the quality of life even up to one year after discharge. The aim of this study is to understand if COVID-19 related acute respiratory distress syndrome has a worse impact on the quality of life one year after discharge when compared with non-COVID-19 acute respiratory distress syndrome.

In this study, the investigators aim to observe the change in alveolar macrophage function during acute lung injury.

Postoperative acute lung injury (ALI) during the first 72 hours after liver transplantation is not uncommon. Injury may occur because liver transplantation is often associated with prolonged operative time, large volumes of fluid administration and transfusion, as well as inflammatory responses related to ischemia-reperfusion injury. For more precise perioperative fluid and hemodynamic management, modern monitoring systems, such as the pulse contour cardiac output (PiCCO) system, have been devised and reported in recent years. The PiCCO system uses the thermodilution technique to determine the cardiac index (CI) and thoracic fluid indices such as the intrathoracic blood volume index (ITBVI), extravascular lung water index (EVLWI), and pulmonary vascular permeability index (PVPI), all of which may reflect pulmonary fluid and injury status. However, perioperative changes in thoracic fluid indices in liver transplantation and their associations with postoperative ALI are not yet clear. In this study, the investigators aimed to determine patterns of change in perioperative thoracic fluid indices and compare these changes in recipients who did or did not develop postoperative ALI. Furthermore, the investigators will also try to determine the potential risk factors following liver transplantation.
