Active clinical trials for "Respiratory Distress Syndrome"

RAGE, the receptor for advanced glycation end products, is a novel marker of alveolar epithelial type I cell injury. Soluble RAGE (sRAGE) is elevated in the plasma and in the pulmonary edema fluid from patients with ALI/ARDS, but one should acknowledge that the RAGE/NF-B axis is also involved in the pathophysiology of various other conditions. Few data are available about the levels of soluble forms and ligands of RAGE in the setting of ALI/ARDS. The purpose of this observational prospective study is to describe soluble forms (sRAGE, esRAGE) and ligands of RAGE (HMGB-1, S100A12, AGEs) levels in ICU patients with ALI/ARDS.

Despite improving in the treatment of acute respiratory distress syndrome (ARDS), this affection keep an elevate rate of death. The strategy of mechanical ventilation is more and more under definite protocol, following large strength randomized studies. Although, it doesn't exist today element allowing to adjust the level of Positive End-Expiratory Pressure (PEEP) with improvement in patient's survival. The investigators proposed in this study to determinate the level of PEEP adjust to obtain the better arterial oxygen transport (TaO2). The investigators going to conduct a physiologic, observational, none controlled study. All patients hospitalized in intensive care unit of Pontchaillou hospital with ARDS criteria and without specific exclusion criteria will be included. Primary objective is to looking for the optimum level of PEEP for TaO2.

Acute respiratory distress syndrome (ARDS) is a severe lung condition that can result from a bacterial infection in the lungs. Viral infections may impair the body's immune system response to bacteria, which may lead to more serious lung injury. This study will evaluate the association between the immune response and ARDS severity in people who have ARDS plus a viral infection.

Acute lung injury (ALI)/Acute Respiratory Distress Syndrome (ARDS) is a severe lung condition that causes respiratory failure. This study will examine if differences in genes and biomarkers involved in the inflammation and blood clotting process may affect the severity of and recovery from ALI/ARDS in children hospitalized with the condition.

Prone position ventilation was used 220 times in 44 out of 68 patients with severe COVID-19 induced ARDS treated with VV-ECMO. PPV treated patients did not benefit from PPV and the incidence of PPV related adverse events was high

Respiratory disorders are the leading cause of respiratory failure in children. Thousands of children are admitted to a pediatric intensive care unit each year and placed on mechanical ventilators. Despite over 40 years since the first pediatric-specific ventilator was designed, there has been no specific cardiopulmonary directed therapy that has proven superior. While mechanical ventilation is generally lifesaving, it can be associated with adverse events. There is evidence building to suggest that adopting a lung protective ventilation strategy by the avoidance of lung over-distension and collapse reduces death. Therefore, timely discovery of these two lung conditions is extremely important in order to mitigate the effects associated with positive pressure mechanical ventilation. The investigators research team has extensive research experience with a non-invasive and radiation free medical device called electrical impendence tomography (EIT). EIT is intended to generate regional information of changes in ventilation. Meaning it can detect this collapse and overdistension. This additional source of information could help fine tune the mechanical ventilator. A baseline of understanding of how often this occurs in the patients the investigators serve is required. Therefore the investigators propose an EIT observation study in their pediatric ICU patient population.

The American-European Consensus Conference (AECC) and the Berlin definitions of the Acute Respiratory Distress Syndrome (ARDS) could be adequate for epidemiologic studies, but it is not adequate for inclusion of patients into therapeutic clinical trials. Despite recent reports on the effects of standardized ventilator settings on PaO2/FIO2 and fulfillment of AECC and Berlin definitions of ARDS, it is still a matter of debate whether the assessment of hypoxemia at 24 hours is the most appropriate tool for stratifying lung severity in patients with ARDS. The investigators will perform an observational, multicenter, prospective audit in a network of intensive care units in Spain and China for validating and confirming that the assessment of hypoxemia at 24 hours after ARDS onset is the most valuable tool for stratifying and predicting outcome in patients with ARDS.

Pulmonary contusion (PC) is a significant problem after blunt trauma that may often lead to acute respiratory distress syndrome (ARDS) and in some patients, death. Although the pathophysiology is incompletely understood, it is clear that there is a biochemical process involving changes in the inflammatory milieu after contusion which occurs in addition to simple direct mechanical injury to the lung. The relationship of severity of contusion on imaging, disturbances in the inflammatory phenotype, and outcome is unknown. This is a prospective, observational study which will evaluate the size and severity of contusion as measured on chest computed tomography (CT). Inflammatory mediators will be measured in the bronchoalveolar lavage (BAL) and in the serum of patients with pulmonary contusion to define the inflammatory nature of the post-contusion lung. The degree of abnormality within the inflammatory parameters will be correlated with lung contusion size and subsequent patient outcomes. These data will be compared to other patient groups: 1) Trauma patients without chest injury who are mechanically ventilated; 2) Uninjured patients undergoing elective surgical procedures that will require intubation and mechanical ventilation; 3) Patients in the Medical ICU who are mechanically ventilated with acute respiratory failure. The hypothesis tested within this study is resolution of lung injury is dependent upon the presence of Tregs in the alveolar space.

The aim of the study is to compare the efficiency on respiratory failure regression of high-flow nasal oxygen therapy versus standard oxygen in patients admitted to the ED for de novo acute respiratory failure.

We hypothesize that combined critical care ultrasound and PAC monitoring-oriented therapy protocol (CUP protocol), would improve prognosis of patients of ARDS with right ventricular dysfunction. Therefore, the overall goal of the study is: 1) To build the combined critical care ultrasound and PAC monitoring-oriented therapy protocol （CUP Protocol）in detail for patients of ARDS with RV dysfunction. Advantage of CUP protocol is that it directly aims at key parameters that we need for the prevention and treatment of such patients; we could improve the mechanical ventilation protocol, unequal pulmonary lesions, hemodynamics management and reduce pulmonary artery pressure according to these parameters, so that to improve the prognosis of the patients.2) To verify the value of CUP Protocol in ARDS with ACP.
