Active clinical trials for "Acute Lung Injury"

This is a case series of patients with COVID-19 admitted to the largest university hospital in Sao Paulo, Brazil, during the 2020 COVID-19 pandemic. Data will be collected prospectively and retrospectively. The main objective is to describe the characteristics of critically ill patients with COVID-19 and their clinical outcomes, and to identify risk factors associated with survival, to inform clinical decision-making and to guide the strategy to mitigate the epidemic, both within each hospital and ICU and in public health management.

In mechanically ventilated patients the PaO2/FiO2 ratio might not be the best reflection of the severity of ARDS. It does not incorporate variables and settings used during mechanical ventilatory support such as the positive end expiratory pressure (PEEP), inspiratory time to expiratory time ratio (Ti:Te), and the peak alveolar pressure (Palv). The aim is to identify a new oxygenation index for stratification of severity of ARDS

The investigators are planning to perform a secondary analysis of an academic dataset of 1,303 patients with moderate-to-severe acute respiratory distress syndrome (ARDS) included in several published cohorts (NCT00736892, NCT02288949, NCT02836444, NCT03145974), aimed to characterize the best early model to predict duration of mechanical ventilation and mortality in the intensive care unit (ICU) after ARDS diagnosis using machine learning approaches.

The Superior Vena cava Respiratory Collapse Index (cVCS) is a haemodynamic parameter measured exclusively by transoesophageal ultrasound (TEE), which is used to assess cardiac precharge-dependence status. This may be an important prognostic factor in ARDS because it is a sign of hypervolemia and right heart failure.

This study aims at describing the frequency, timing and type of pulmonary complications detected with lung ultrasound in critically-ill parturients in admitted to a high-dependency unit in Freetown, Sierra Leone.

Tracheal intubation in the ICU is associated with significant complications and morbidity. Desaturation is among the most frequent and hazardous complication, occurring in almost one out of four intubations, that may in some instances lead to cardiac arrest; despite appropriate preoxygenation. Non-invasive ventilation may help improve preoxygenation but does not allow for apneic oxygenation and may not be performed in patients with neurological impairment. High flow nasal canula oxygen is increasingly used in the ICU in patients with acute hypoxemic respiratory failure and may be used to improve preoxygenation. It is currently used in our ICU for that purpose. Because high flow nasal canula oxygen is our first line oxyten therapy for patients with acute respirtory distress syndrome, we sought to determine its use as a means to ensure preoxygenation in those ARDS patients that require intubation.

To study the association of the thoracic fluid content and acute lung injury during liver transplantation.

The purpose of this study is to compare lung recruitment in acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) based on lower inflection point with transthoracic ultrasonographic assessment of lung recruitment.

Assessment of right ventricular (RV) function in patients with acute respiratory syndrome (ARDS) is warranted because RV failure is frequent and associated with worse outcome. Transthoracic echocardiography is the cornerstone of RV assessment but it remains challenging. Quantification of RV deformation by speckle-tracking imaging echocardiography (STE) is a widely available and reproducible technique that readily provides an integrated analysis of all segments of the RV. This study aims to investigate the accuracy of STE-derived strain parameters in assessing RV function during ARDS.
