Active clinical trials for "Acute Lung Injury"

Try to collect about 350 cases of acute necrotizing pancreatitis at the First Affiliated Hospital with Nanjing Medical University and Nanjing General Hospital of Nanjing Military Command. Then the investigators studied the incidence and the risk factors of ARDS in patients with acute necrotizing pancreatitis.

An assessment of early management of moderate-severe ARDS in the United States, including ventilator management and use of rescue therapy.

The acute respiratory distress syndrome (ARDS), characterized by alveolar flooding with protein-rich pulmonary edema fluid, is one of the most common disease in the intensive care unit (ICU) throughout the world. In recent years, much effort has been focused on the biological markers for their potential values to diagnose ARDS and outcomes. ARDS is generally accompanied by the disruption in alveolar-capillary barrier permeability, which subsequently caused an influx of neutrophils into the interstitium and alveolar space. It was reported that the aggregation, adhesion activation and release proteases of neutrophils are the key pathogenesis of ARDS pulmonary edema. Neutrophil Elastase (HNE), the most crucial protease generated in neutrophil azurophilic granules, plays an important role in various inflammations, especially the lung injury. The destructive action of HNE on almost all extracellular matrix influences cell signaling through cleavage of surface receptors. Once released in circulation, HNE is rapidly inactivated by conjugation with PI3. This local inhibitor reduces HNE mediated tissue injury and inflammation. Thus, the investigators plan to conduct a cohort study with repeated measures to examine the diagnostic and prognostic value of HNE and PI3 for ARDS.

Neonatal acute respiratory distress syndrome(ARDS) is a rare but often severe respiratory disorder. The incidence remains unclear and mortality is about 30%-60%. It is characterized by acute, refractory hypoxemia, persistent respiratory distress and decreased lung compliance. Evaluation and comparison of various clinical studies conducted were hindered by a lack of uniformity in diagnostic criteria.

The acute respiratory distress syndrome(ARDS)has a high morbidity and mortality in patients admitted to intensive care units(ICUs). It represents a significant public health issue. No large nationwide, multicenters study of ARDS has been conducted in China. The purposes of this study are to analyse: 1)the incidence and outcomes of ARDS in ICU; 2) factors associated the mortality ; and 3) risk factors for development of ARDS .

The influenza A/H1N1v pandemic virus causes severe pneumonia that can lead to acute respiratory distress syndrome and death even in healthy young individuals. The respective roles of viral replication, bacterial infection and immune alterations of the host during such severe influenza H1N1v infection need to be clarified in order to optimize patients care. In this context, we aim to study immune and virological parameters in bronchoalveolar lavage fluid during severe influenza A/H1N1v infection with pulmonary involvement in intensive care unit. Results will be correlated to bacterial or viral pulmonary co-infections and to peripheral blood immune and virological parameters.

The investigators aim to compare four different lung recruitment techniques (described in literature) to Computed tomography scan analysis.

The investigators aim to compare the respiratory mechanics in acute lung injury (ALI)/acute respiratory diseases syndrome (ARDS) patients with and without pleural effusion.

PALIVE 1 is an observational multicenter study on mechanical ventilation strategies used in children with an acute lung injury (ALI). The objective of the study is to describe mechanical ventilation strategies in children with an ALI. Our hypothesis is that daily clinical practice is heterogenous among pediatric intensivists as few pediatric data exists on optimal mechanical ventilation strategies in this group of patients. Furthermore, different strategies may affect patient outcome.

Research question: Are the ventilatory variables related to mechanical power associated with the outcome of subjects who received mechanical ventilation (MV) for Acute Respiratory Distress Syndrome (ARDS) secondary to pneumonia (NMN) due to COVID-19?
