Active clinical trials for "Acute Lung Injury"

Nasal high flow is widely used in critically ill patients admitted to the intensive care unit (ICU) for acute hypoxemic respiratory failure. It has been shown to improve patient comfort, increase oxygenation and reduce need for intubation in some patients. The Respiratory Oxygenation (ROX) index has been established as a simple tool to help clinicians identify those patients who will succeed and those who will fail under nasal high flow and therefore predict the need for intubation. However, when nasal high flow therapy is successful, little is known as to how and when weaning of this device should be performed and what are the predictors of a safe withdrawal of the device. The objectives of this retrospective exploratory study are to identify a cut-off value of the ROX index predictive of success of the withdrawal trial, to describe a one-year use of the withdrawal trial; to describe the ROX value closest to weaning from nasal high flow, and to identify factors associated with success or failure of the withdrawal trial from nasal high flow therapy in patients receiving nasal high flow therapy.

The Acute Respiratory Distress Syndrome (ARDS) is one of common clinical critically diseases. In the United States, the incidence of ARDS reaches 31%, which is one of the main causes of death in patients. There is no unified treatment process for ARDS currently and the treatment measures are not yet standardized, so the standardization of ARDS treatment processes is needed to reduce mortality in patients. Following the evidence-based medicine principles and six-step treatment standards of ARDS, this study uses the method of multi-center randomized controlled clinical trials to evaluate the standardized treatment process of ARDS, which provides the basis for the standardized treatment of ARDS.

We wish to prospectively assess the burden of, management and therapeutic approaches to, and outcomes from acute hypoxaemic respiratory failure requiring ventilatory support, during the winter months in both the northern and southern hemispheres. We wish to specifically examine the contribution of ARDS as defined by the Berlin Definition to the burden of hypoxaemic respiratory failure. Why? The purpose of this study is to provide new and current data on the disease burden of acute hypoxemic respiratory failure and ARDS. It will answer the following questions: What is the frequency and disease burden of acute hypoxaemic respiratory failure in winter? What are the aetiologies of acute hypoxaemic respiratory failure requiring ventilatory support? What is the incidence of ARDS based on the Berlin definition within this patient cohort? What is the mortality from ARDS within this cohort, and how does this vary based on ARDS severity? What is the natural history of ARDS? What are the key patterns of therapeutic resource utilization, particularly approaches to sustain gas exchange, in these patients? When? The study is performed over a 4 week period between February 1st and March 31st 2014 in the Northern Hemisphere and June 1st to August 31st in the Southern Hemisphere. What data is required? A basic dataset is collected on all patients admitted with acute acute hypoxaemic respiratory failure requiring ventilatory support, with a more detailed dataset collected on patients diagnosed with ARDS.

The characteristics and outcomes of a mixed group of critically ill patients who received mechanical ventilation are not known in China. A 1 month Cross-section survey will be performed with the aim of describing the characteristics and outcomes of conventional mechanical ventilation and treatment of acute respiratory distress syndrome in intensive care units in China.

The objective of this study is to evaluate the association between positive end-expiratory pressure (PEEP) setting and cardiac function, as measured by cardiac index, in patients with acute respiratory distress syndrome (ARDS) who were managed on the NHLBI ARDS Network Fluid and Catheter Treatment Trial (FACTT) fluid protocols.

Mortality rates in children with pediatric acute respiratory distress syndrome (PARDS) are higher in Asia compared to other regions. In adults with acute respiratory distress syndrome, the only therapy that improves mortality rates is a lung protective ventilation strategy. The pediatric ventilation recommendations by the Pediatric Acute Lung Injury Consensus Conference (PALICC) are extrapolated from evidence in adults, including ventilation with low tidal volume, low peak/plateau pressures and high end expiratory pressure. A recent retrospective study of ventilation practices in Asia including Singapore showed that a majority of patients with PARDS were being ventilated with high tidal volume, high peak pressure and low end expiratory pressure, not in compliance with PALICC recommendations. We postulate that currently used ventilation strategies could have contributed to the high PARDS mortality rates in Asia. We aim to determine if implementing a ventilation bundle comprising PALICC recommendations lowers PARDS and pediatric intensive care unit (PICU) mortality rates.

Central venous pressure (CVP) is characterized by a low-frequency pleural-dependent as well as a high-frequency cardiac pulsatile component. The aim of the study is to compare the low-frequency component of CVP with the esophageal pressure (Pes), as surrogate of pleural pressure, to estimate trans-pulmonary pressure (PL).

Novel coronavirus (SARS-CoV-2: severe acute respiratory coronavirus 2) pneumonia often develop the acute respiratory distress syndrome (ARDS). Lung protective ventilation strategy consisting of low tidal volume and high positive end-expiratory pressure (PEEP) is recommended. However, it is not clear whether injured lungs from SARS-CoV-2 pneumonia have the same mechanical properties, especially response to PEEP as common ARDS. Therefore, the investigators propose an observational study to analyze respiratory mechanics and lung recruitablity using EIT (electrical impedance tomography) in patients with ARDS due to SARS-CoV-2 pneumonia.

Flow controlled ventilation (FCV) is a fairly new mode of mechanical ventilation, consisting of a constant inspiratory and expiratory flow. Inspiration is thus comparable to volume controlled ventilation (VCV). The actively controlled, constant flow during expiration is unique. FCV is known to minimize dissipated energy to the lung [ref] and is therefore supposed to aid in lung protective ventilation. The VICAR study is designed as a prospective single cohort crossover trial. The intervention consists of a sequence of respiratory modes: baseline pressure controlled ventilation (PCV) during 5 minutes, followed by 30 minutes of FCV with an evone respirator (Ventinova Medical B.V., Eindhoven, The Netherlands) and eventually 30 minutes of VCV. Every participant will receive the intervention. Respiratory rate (RR), positive end-expiratory pressure (PEEP) and inspiratory fraction of oxygen (FiO2) will be held constant. According to the manufacturers guidelines, an I:E ratio of 1:1 will be pursued during FCV. During FCV, the respirator will be set with the same PIP as during baseline PCV. For VCV, the same tidal volume as during baseline PCV will be set.

This protocol provides access to eculizumab treatment for participants with severe COVID-19.
